Unsterblichkeit Wikipedia

Posted: November 23, 2016 at 10:01 pm

Unsterblichkeit ist die Vorstellung eines zeitlich unbegrenzten Lebens in physischer oder spiritueller Form.

Der Beweis fr biologische Unsterblichkeit bei hher entwickelten tierischen und pflanzlichen Lebensformen steht noch aus. Bei den meisten bekannten Tieren nimmt die Fhigkeit zur Selbstregeneration im Verlaufe des Lebens aus verschiedenen Grnden jedoch ab. Sollte ein Wesen existieren, das Beschdigungen in demselben Mae reparieren kann, in dem sie auftreten, wre es wohl zeitlich unbegrenzt lebensfhig.

Diese Unsterblichkeit ist naturgem in der Realitt dadurch begrenzt, dass die Organismen durch uere Einflsse und Krankheiten sehr wohl zu Tode kommen knnen. Daher wird diese Unsterblichkeit als potenzielle oder relative Unsterblichkeit bezeichnet.

Es wird angenommen, dass das Altern eine Folge des Evolutionsprozesses ist warum sich allerdings Altern als Selektionskriterium durchgesetzt hat, bleibt bisher eine offene Frage. Der programmierte Zelltod und das Problem sich verringernder Telomere finden sich bereits in einfachsten Organismen. Dies knnte die Folge eines Kompromisses zwischen einer Vermeidung von Krebs einerseits und dem Altern andererseits sein.

Unter den modernen Theorien zur Evolution des Alterns finden sich unter anderem:

Bereits heute ist die Lebensspanne in den Industrienationen weit ber dem Niveau frherer Tage. Dazu haben Fortschritte bei der Hygiene, Ernhrung, dem Lebensstandard und ganz allgemein in der medizinischen Versorgung gefhrt. Durch die Weiterentwicklung von Technologien in den Bereichen Gentherapie, Zelltherapie, regenerative Medizin, Biomedizin und Mikro- bzw. Nanotechnologie ist damit zu rechnen, dass ein weiterer signifikanter Anstieg der Lebenserwartung mglich wird. Wie blich werden sich diese Entwicklungen schrittweise vollziehen, sodass bereits mittelfristig mit greifbaren Resultaten gerechnet werden kann, die mit der Zeit immer umfassender und wirkungsvoller werden sollten. Robert Freitas, ein Wissenschaftler auf dem Gebiet der theoretischen Nanorobotik, konstruiert Modelle von Nanomaschinen, die in Zukunft dauerhaft im menschlichen Krper eingesetzt werden knnten, um Pathogene zu eliminieren, Krebs in Schach zu halten und Reparaturarbeiten durchzufhren. Somit knnte mglicherweise der Alterungsprozess zum Stillstand gebracht werden, indem es zu einem Gleichgewicht zwischen den Verschleierscheinungen einerseits und regenerativen Prozessen andererseits kommt.

Aubrey de Grey entwickelt Theorien ber das menschliche Altern, das er wie eine Krankheit auf ungnstige biochemische Prozesse zurckfhrt, die durch gezieltes Beeinflussen gestoppt oder umgekehrt werden knnen. Das von ihm vorgeschlagene Verfahren, das er als Strategien zur Bekmpfung des Alterns (Strategies for Engineered Negligible Senescence, kurz SENS) bezeichnet, basiert auf sieben von ihm propagierten Angriffspunkten. De Grey ist Mitbegrnder (gemeinsam mit David Gobel) und leitender Wissenschaftler des Projektes Methusalem-Maus-Preis, das die Beschleunigung und Frderung der Forschung auf dem Gebiet der Lebensverlngerung zur Aufgabe hat. Das durch Spenden stndig wachsende Preisgeld, das im Juni 2008 einen Stand von 2,8 Millionen EUR (4,4 Millionen USD) betrug, wird an Labore vergeben, deren Arbeit die Lebensspanne von Musen nachweislich deutlich verlngern kann. Die Intention des Preises ist es, dass berzeugende Erfolge im Mausmodell groe Investitionen fr das bertragen der Ergebnisse auf den menschlichen Einsatz mit sich bringen wrden.

Bei ausreichend tiefen Temperaturen, in der Praxis 196 C, kommt jede Form von Bioaktivitt im Organismus zum Erliegen; damit wird jeder weitere Verfall des Gewebes gestoppt. Die Kryonik, das Einfrieren des ganzen Krpers oder des Gehirns als Sitz des Bewusstseins, ist eine Hoffnung auf eine Verlngerung des eigenen Lebens fr Menschen, deren Alterungsprozess zu weit fortgeschritten ist oder sein wird, als dass sie von dem technischen Stand der lebensverlngernden Manahmen profitieren knnten oder deren Krankheiten nach aktuellem Stand der Medizin nicht geheilt werden knnen. Die Hoffnung dieser Kryonik-Patienten ist, dass zuknftige Generationen ihre Krankheiten oder das Altern an sich behandeln knnen.

Moderne Kryonikverfahren nutzen zur Konservierung einen als Vitrifizierung bezeichneten Prozess. Bei diesem wird die organische Materie nicht im klassischen Sinne eingefroren. Bei den verwendeten extrem tiefen Temperaturen geht die Biomasse Mensch in eine glashnliche Struktur ber. Damit kommt es nicht zu der ansonsten beobachteten Zellschdigung durch die Bildung von Eiskristallen. Besonders beim Gewebe des Gehirns ist es entscheidend, die exakte Struktur zu konservieren. Nur so besteht die Hoffnung, die darin enthaltenen Informationen die Erinnerungen und das Bewusstsein des Individuums in der Zukunft wiederherstellen zu knnen.

Die Umwandlung eines Menschen in einen Cyborg sagt im Wesentlichen aus, dass der Mensch durch technische Implantate erhalten oder verbessert wird. In Anfngen kann eine solche Perspektive bereits heute bei der Entwicklung knstlicher Herzen gesehen werden, obwohl die mensch-gemachten Systeme dem biologischen Vorbild noch klar unterlegen sind. Cyborgologie umfasst potentiell die Integration von Neuro-Implantaten zum Erhalt und zur Erweiterung kognitiver Mglichkeiten und den Austausch biologischer Organe und Systeme durch leistungsfhigere technische Alternativen.

Unter Mind-Uploading versteht man die Auslagerung der bewusstseinsrelevanten Teile des Gehirns in ein digitales Medium. Durch diesen Prozess knnte man zum einen eine digitale Alternative zur Kryonik als konservierende Manahme schaffen. Andererseits knnte es auch mglich sein, das gespeicherte Bewusstsein in einer digitalen virtuellen Welt zum Leben zu erwecken. Grundstzlich ist die Frage legitim, inwieweit diese Simulation einen Realittsanspruch erheben knnte. Allerdings ist jeder Eindruck, den unser Bewusstsein von der Umwelt erhlt, auch nicht viel mehr als das Ergebnis von im Gehirn verarbeiteten Sinneseindrcken und daher subjektiv.

Alternativ wre auch denkbar, das Bewusstsein bei Bedarf in eine geeignete physische Einheit (z.B. Roboter) zu transferieren, dessen Sinneseindrcke zu verarbeiten und ber Adduktoren (z.B. Arme oder Beine) mit der Umgebung zu interagieren.

Fr das Erlangen von Unsterblichkeit bietet die Methode des Uploading einen guten Sicherheitsvorteil, da man vor physischen krperlichen Schden sicher wre und man zustzlich Backups auf rumlich verteilten digitalen Systemen speichern knnte. Der entscheidende Nachteil ist die neue physische Form bzw. das Fehlen einer solchen. Es besteht natrlich kein Konsens bezglich der prinzipiellen Realisierbarkeit von Mind-Uploading, da diese Frage von der geistesphilosophischen Auffassung abhngt, es knnte sich zum Beispiel die Frage stellen, ob eine angenommene Subjektivitt verloren ginge.

Die Idee der Unsterblichkeit gehrt in nahezu allen Religionen zum festen Glaubensbestand. Dabei haftet dem verehrten Gott oder der Gtterwelt das Attribut des Unsterblichseins an, wird aber auch der menschlichen Seele Unsterblichkeit zugebilligt. Im Daoismus bestand in vielen Strmungen die berzeugung, der Mensch knne seinen Geist und Krper durch Kultivierung soweit entwickeln, dass er physische Unsterblichkeit erlangt und ein Xian wird, in anderen Strmungen des Daoismus handelt es sich um eine nicht-physisch gemeinte spirituelle oder geistige, teilweise nachtodliche Unsterblichkeit. Die chinesische Alchemie widmete sich bis zum Ende der Tang-Zeit vornehmlich der Suche nach dem Elixier der Unsterblichkeit, der Quanzhen-Daoismus wandte sich explizit vom Ziel der physischen Unsterblichkeit ab.

In der Bibel gibt es einige Stellen, die sich auf relative physische Unsterblichkeit beziehen (nachfolgende im Wortlaut aus der Lutherbibel, Ausgabe Revidierte Fassung 1984 (1985) der sterreichischen Bibelgesellschaft), freilich nur bedingt durch gttlichen Willen. Nachfolgende Textpassagen stammen smtlich von den vier Evangelisten.

Nach: Als Petrus diesen sah, spricht er zu Jesus: Herr, aber was wird mit diesem? Jesus spricht zu ihm: Wenn ich will, dass er bleibt bis ich komme, was geht es dich an? Folge du mir nach! Da kam unter den Brdern die Rede auf: Dieser Jnger stirbt nicht (Johannes 21,22) Ich sage euch aber wahrlich: Einige von denen, die hier stehen, werden den Tod nicht schmecken, bis sie das Reich Gottes sehen (Lukas 9,27) Und er sprach zu ihnen: Wahrlich ich sage euch: Es stehen einige hier, die werden den Tod nicht schmecken, bis sie sehen das Reich Gottes kommen mit Kraft. (Markus 9,1) Bei Lukas und Markus findet sich sogar fast wrtliche bereinstimmung. Anzumerken ist, dass insbesondere das Christentum das Leben nach dem Tode sowie die Auferstehung betont. Obengenannte Bibelstellen werden daher selten zitiert, da sie meist in der christlichen Theologie einen untergeordneten Stellenwert besitzen. In der christlichen Bibel selbst gibt es ungeachtet des Topos ewiges Leben/Unsterblichkeit Berichte ber besonders langlebige Individuen wie etwa Methusalem oder die Erzvter.

Die philosophische Argumentation fr die Unsterblichkeit (der Seele oder des Geistes) geht u.a. zurck auf Platon. Das Hauptargument lautet: Die geistige Seele kann nicht sterben, d.h. zerstrt oder zerteilt werden, weil sie eine einfache, nicht-zusammengesetzte, immaterielle Substanz ist.

Immanuel Kant, der sich zum Christentum bekannte, formulierte 1793 in seiner religionsphilosophischen Schrift Die Religion innerhalb der Grenzen der bloen Vernunft seine Doktrin fr eine Vernunftreligion. Kant postuliert darin die Mglichkeit der Existenz Gottes und der Unsterblichkeit der Seele, die somit Gegenstand eines rationalen Glaubens sein knnen. Allerdings lehnte er metaphysische Beweise hierfr ab.

Theres more to it than meets the eye with Sensor-Track. Our scientists developed the track using a base material of PVC, which was selected for its high tensile strength, flexibility and chemical resistance. This base material was then further re-enforced using an encapsulated micro-weave fabric, to maximise tear resistance while maintaining the desired balance between weight, thickness and strength. We then experimented with custom texture finishes, to determine the optimum amount of friction to allow the cars tyres to grip the track, but allow players to drift, or oversteer with opposite lock, through corners. The brief was to replicate as closely as possible the feel and interaction of a real car on a real race track.

The result is a track system that no matter how big you wish to go, is still portable enough to carry to your friends or the park, in a low weight and compact storage box. No lumpy bits of plastic or metal ensure Sensor-Track can also be truly flat packed for the most efficient stowage. You wont fill a whole wardrobe no matter how large your collection of track pieces becomes and your track and cars are 100% compatible with everyone elses, so you can go large. Very, very large.

Throughout the development we worked closely with model racing enthusiasts to build a modular system of track parts that delivers the maximum flexibility to design and build different race circuits. You can now take Le Mans to your mates, with extra Sensor-Track pieces such as short & sharp (R1) bends for tight circuits and wide sweeping (R2) bends, bottlenecks, and crossovers. Sensor Track allows you to build realistic representations of famous race tracks like Silverstone & Nurburgring! See the Track Builder where building tracks of the world are a reality.

OpenAI has been backed by tech luminaries to the tune of $1bn.

Microsoft and Elon Musks artificial intelligence research group have signed a partnership.

Terms of the partnership will see OpenAI use Microsofts cloud, Azure, for its large-scale experiments.

The non-profit AI research organisation that is backed by Elon Musk, Peter Thiel, and the likes of Amazon Web Services and Infosys to the tune of $1bn, has the goal of advancing digital intelligence in a way that, is most likely to benefit humanity as a whole, unconstrained by a need to generate financial return.

The partnership comes about partly due to Microsofts work on its Cognitive Toolkit, a

system for deep learning that is used to speed advances in areas such as speech and

image recognition, and because Azure already supports AI workloads with tools such as Azure Batch and Azure Machine Learning.

OpenAI has been an early adopter of Microsofts still in beta N-Series machines, a cloud computing service that is powered by Nvidia and now the two will partner on finding ways to advance AI research.

OpenAI said in a blog post: In the coming months we will use thousands to tens of thousands of these machines to increase both the number of experiments we run and the size of the models we train.

Microsoft has been pushing ahead of the cloud market when it comes to investing in artificial intelligence and introducing it into products. Cortana is probably the most well known of its AI offerings but it has also been applying the technology to medicine and bots, which it has begun rolling out to online help services.

Microsoft also today launched its Azure Bot Service. The service is designed to help developers to cost effectively host their bots on Azure.

OpenAI was created in December 2015 with a group of founding members that includes the like of Elon Musk. Ilya Sutskever is the research director and Greg Brockman is the CTO.

Artificial Intelligence (AI) is the area of computer science focusing on creating machines that can engage on behaviors that humans consider intelligent. The ability to create intelligent machines has intrigued humans since ancient times and today with the advent of the computer and 50 years of research into AI programming techniques, the dream of smart machines is becoming a reality. Researchers are creating systems which can mimic human thought, understand speech, beat the best human chess player, and countless other feats never before possible. I focused on this area for my capstone because I thought it would be an original idea and also would be interesting to investigate and determine if artificial intelligence is a good concept or a bad to the human life. I wish to accomplish how it came about, the reasoning behind artificial intelligence, and where I think it will go in the future based on my research on this topic. . The Story Behind it All. Artificial intelligence has been around for longer then most people think. We all think that artificial intelligence has been in research for about 20 years or so. In all actuality after thousands of years of fantasy, the appearance of the digital computer, with its native, human-like ability to process symbols, made it seem that the myth of the man-made intelligence would finally become reality. The history of artificial intelligence all started in the 3rd century BC. Chinese engineer Mo Ti created mechanical birds, dragons, and warriors. Technology was being used to transform myth into reality.1. Much later, mechanical ducks and humanoid figures, crafted by clockmakers, endlessly amused the Royal courts of the Enlightenment-age Europe. It has long been possible to make machines that looked and moved in human-like ways.3 Machines that could spook and awe the audience - but creating a model of the mind, in that day in time were off limits.

Artificial intelligence

Artificial intelligence is technology and a branch of computer science that studies and develops intelligent machines and software. Major AI researchers and textbooks define the field as "the study and design of intelligent agents", where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. John McCarthy, who coined the term in 1955, defines it as "the science and engineering of making intelligent machines". AI research is highly technical and specialised, deeply divided into subfields that often fail to communicate with each other. Some of the division is due to social and cultural factors: subfields have grown up around particular institutions and the work of individual researchers. AI research is also divided by several technical issues. There are subfields which are focused on the solution of specific problems, on one of several possible approaches, on the use of widely differing tools and towards the accomplishment of particular applications. The central problems of AI research include reasoning, knowledge, planning, learning, communication, perception and the ability to move and manipulate objects. General intelligence is still among the field's long term goals. Currently popular approaches include statistical methods, computational intelligence and traditional symbolic AI. There are an enormous number of tools used in AI, including versions of search and mathematical optimization, logic, methods based on probability and economics, and many others.

For the commander facing an unconventional adversary; for the intelligence analyst trying to find the needle in the data haystack; or for the operator trying to maintain complex systems under degraded conditions or attack, todays warfighter faces problems of scale, complexity pace and resilience that outpace unaided human decision making. Artificial Intelligence (AI) provides the technology to augment human analysis and decision makers by capturing knowledge in computers in forms that can be re-applied in critical situations. This gives users the ability to react to problems that require analysis of massive data; demand fast-paced analysis and decision making, and that demand resilience in uncertain and changing conditions. AI offers the technology to change the human role from in-the-loop controller to on-the-loop thinker who can focus on a more reflective assessment of problems and strategies, guiding rather than being buried in execution detail. By creating technology that allows captured knowledge to continually evolve to incorporate new experience or changing user's needs, AI-based analysis and decision support tools can continue to assist the user long after its original knowledge becomes obsolete.

Key Technologies Artificial Intelligence is focused on the research, development, and transition of technologies that enable dynamic and real-time changes to knowledge bases that allow for informed, agile, and coordinated Command and Control decisions

The Artificial Intelligence group has an emphasis in four key thrust areas:

Artificial Intelligence is one of several Research Areas for the Informatics Laboratory.

Artificial Intelligence in Medicine: An Introduction

Posted: at 10:00 pm

Acknowledgement The material on this page is taken from Chapter 19 of Guide to Medical Informatics, the Internet and Telemedicine (First Edition) by Enrico Coiera (reproduced here with the permission of the author). Introduction

From the very earliest moments in the modern history of the computer, scientists have dreamed of creating an 'electronic brain'. Of all the modern technological quests, this search to create artificially intelligent (AI) computer systems has been one of the most ambitious and, not surprisingly, controversial.

It also seems that very early on, scientists and doctors alike were captivated by the potential such a technology might have in medicine (e.g. Ledley and Lusted, 1959). With intelligent computers able to store and process vast stores of knowledge, the hope was that they would become perfect 'doctors in a box', assisting or surpassing clinicians with tasks like diagnosis.

With such motivations, a small but talented community of computer scientists and healthcare professionals set about shaping a research program for a new discipline called Artificial Intelligence in Medicine (AIM). These researchers had a bold vision of the way AIM would revolutionise medicine, and push forward the frontiers of technology.

AI in medicine at that time was a largely US-based research community. Work originated out of a number of campuses, including MIT-Tufts, Pittsburgh, Stanford and Rutgers (e.g. Szolovits, 1982; Clancey and Shortliffe, 1984; Miller, 1988). The field attracted many of the best computer scientists and, by any measure, their output in the first decade of the field remains a remarkable achievement.

In reviewing this new field in 1984, Clancey and Shortliffe provided the following definition:

Much has changed since then, and today this definition would be considered narrow in scope and vision. Today, the importance of diagnosis as a task requiring computer support in routine clinical situations receives much less emphasis (J. Durinck, E. Coiera, R. Baud, et al., "The Role of Knowledge Based Systems in Clinical Practice," in: eds Barahona and Christenen, Knowledge and Decisions in Health Telematics - The Next Decade, IOS Press, Amsterdam, pp. 199- 203, 1994), So, despite the focus of much early research on understanding and supporting the clinical encounter, expert systems today are more likely to be found used in clinical laboratories and educational settings, for clinical surveillance, or in data-rich areas like the intensive care setting. For its day, however, the vision captured in this definition of AIM was revolutionary.

After the first euphoria surrounding the promise of artificially intelligent diagnostic programmes, the last decade has seen increasing disillusion amongst many with the potential for such systems. Yet, while there certainly have been ongoing challenges in developing such systems, they actually have proven their reliability and accuracy on repeated occasions (Shortliffe, 1987).

Much of the difficulty has been the poor way in which they have fitted into clinical practice, either solving problems that were not perceived to be an issue, or imposing changes in the way clinicians worked. What is now being realised is that when they fill an appropriately role, intelligent programmes do indeed offer significant benefits. One of the most important tasks now facing developers of AI-based systems is to characterise accurately those aspects of medical practice that are best suited to the introduction of artificial intelligence systems.

In the remainder of this chapter, the initial focus will thus remain on the different roles AIM systems can play in clinical practice, looking particularly to see where clear successes can be identified, as well as looking to the future. The next chapter will take a more technological focus, and look at the way AIM systems are built. A variety of technologies including expert systems and neural networks will be discussed. The final chapter in this section on intelligent decision support will look at the way AIM can support the interpretation of patient signals that come off clinical monitoring devices.

In his opinion, there were no ultimately useful measures of intelligence. It was sufficient that an objective observer could not tell the difference in conversation between a human and a computer for us to conclude that the computer was intelligent. To cancel out any potential observer biases, Turing's test put the observer in a room, equipped with a computer keyboard and screen, and made the observer talk to the test subjects only using these. The observer would engage in a discussion with the test subjects using the printed word, much as one would today by exchanging e-mail with a remote colleague. If a set of observers could not distinguish the computer from another human in over 50% of cases, then Turing felt that one had to accept that the computer was intelligent.

Another consequence of the Turing test is that it says nothing about how one builds an intelligent artefact, thus neatly avoiding discussions about whether the artefact needed to in anyway mimic the structure of the human brain or our cognitive processes. It really didn't matter how the system was built in Turing's mind. Its intelligence should only to be assessed based upon its overt behaviour.

There have been attempts to build systems that can pass Turing's test in recent years. Some have managed to convince at least some humans in a panel of judges that they too are human, but none have yet passed the mark set by Turing.

An alternative approach to strong AI is to look at human cognition and decide how it can be supported in complex or difficult situations. For example, a fighter pilot may need the help of intelligent systems to assist in flying an aircraft that is too complex for a human to operate on their own. These 'weak' AI systems are not intended to have an independent existence, but are a form of 'cognitive prosthesis' that supports a human in a variety of tasks.

AIM systems are by and large intended to support healthcare workers in the normal course of their duties, assisting with tasks that rely on the manipulation of data and knowledge. An AI system could be running within an electronic medical record system, for example, and alert a clinician when it detects a contraindication to a planned treatment. It could also alert the clinician when it detected patterns in clinical data that suggested significant changes in a patient's condition.

Along with tasks that require reasoning with medical knowledge, AI systems also have a very different role to play in the process of scientific research. In particular, AI systems have the capacity to learn, leading to the discovery of new phenomena and the creation of medical knowledge. For example, a computer system can be used to analyse large amounts of data, looking for complex patterns within it that suggest previously unexpected associations. Equally, with enough of a model of existing medical knowledge, an AI system can be used to show how a new set of experimental observations conflict with the existing theories. We shall now examine such capabilities in more detail.

Expert or knowledge-based systems are the commonest type of AIM system in routine clinical use. They contain medical knowledge, usually about a very specifically defined task, and are able to reason with data from individual patients to come up with reasoned conclusions. Although there are many variations, the knowledge within an expert system is typically represented in the form of a set of rules.

There are many different types of clinical task to which expert systems can be applied.

Generating alerts and reminders. In so-called real-time situations, an expert system attached to a monitor can warn of changes in a patient's condition. In less acute circumstances, it might scan laboratory test results or drug orders and send reminders or warnings through an e-mail system.

Diagnostic assistance. When a patient's case is complex, rare or the person making the diagnosis is simply inexperienced, an expert system can help come up with likely diagnoses based on patient data.

Therapy critiquing and planning. Systems can either look for inconsistencies, errors and omissions in an existing treatment plan, or can be used to formulate a treatment based upon a patient's specific condition and accepted treatment guidelines.

Agents for information retrieval. Software 'agents' can be sent to search for and retrieve information, for example on the Internet, that is considered relevant to a particular problem. The agent contains knowledge about its user's preferences and needs, and may also need to have medical knowledge to be able to assess the importance and utility of what it finds.

Image recognition and interpretation. Many medical images can now be automatically interpreted, from plane X-rays through to more complex images like angiograms, CT and MRI scans. This is of value in mass-screenings, for example, when the system can flag potentially abnormal images for detailed human attention.

There are numerous reasons why more expert systems are not in routine use (Coiera, 1994). Some require the existence of an electronic medical record system to supply their data, and most institutions and practices do not yet have all their working data available electronically. Others suffer from poor human interface design and so do not get used even if they are of benefit.

Much of the reluctance to use systems simply arose because expert systems did not fit naturally into the process of care, and as a result using them required additional effort from already busy individuals. It is also true, but perhaps dangerous, to ascribe some of the reluctance to use early systems upon the technophobia or computer illiteracy of healthcare workers. If a system is perceived by those using it to be beneficial, then it will be used. If not, independent of its true value, it will probably be rejected.

Happily, there are today very many systems that have made it into clinical use. Many of these are small, but nevertheless make positive contributions to care. In the next two sections, we will examine some of the more successful examples of knowledge-based clinical systems, in an effort to understand the reasons behind their success, and the role they can play.

In the first decade of AIM, most research systems were developed to assist clinicians in the process of diagnosis, typically with the intention that it would be used during a clinical encounter with a patient. Most of these early systems did not develop further than the research laboratory, partly because they did not gain sufficient support from clinicians to permit their routine introduction.

It is clear that some of the psychological basis for developing this type of support is now considered less compelling, given that situation assessment seems to be a bigger issue than diagnostic formulation. Some of these systems have continued to develop, however, and have transformed in part into educational systems.

DXplain is an example of one of these clinical decision support systems, developed at the Massachusetts General Hospital (Barnett et al., 1987). It is used to assist in the process of diagnosis, taking a set of clinical findings including signs, symptoms, laboratory data and then produces a ranked list of diagnoses. It provides justification for each of differential diagnosis, and suggests further investigations. The system contains a data base of crude probabilities for over 4,500 clinical manifestations that are associated with over 2,000 different diseases.

DXplain is in routine use at a number of hospitals and medical schools, mostly for clinical education purposes, but is also available for clinical consultation. It also has a role as an electronic medical textbook. It is able to provide a description of over 2,000 different diseases, emphasising the signs and symptoms that occur in each disease and provides recent references appropriate for each specific disease.

Decision support systems need not be 'stand alone' but can be deeply integrated into an electronic medical record system. Indeed, such integration reduces the barriers to using such a system, by crafting them more closely into clinical working processes, rather than expecting workers to create new processes to use them.

The HELP system is an example of this type of knowledge-based hospital information system, which began operation in 1980 (Kuperman et al., 1990; Kuperman et al., 1991). It not only supports the routine applications of a hospital information system (HIS) including management of admissions and discharges and order entry, but also provides a decision support function. The decision support system has been actively incorporated into the functions of the routine HIS applications. Decision support provide clinicians with alerts and reminders, data interpretation and patient diagnosis facilities, patient management suggestions and clinical protocols. Activation of the decision support is provided within the applications but can also be triggered automatically as clinical data is entered into the patient's computerised medical record.

One of the most successful areas in which expert systems are applied is in the clinical laboratory. Practitioners may be unaware that while the printed report they receive from a laboratory was checked by a pathologist, the whole report may now have been generated by a computer system that has automatically interpreted the test results. Examples of such systems include the following.

Laboratory expert systems usually do not intrude into clinical practice. Rather, they are embedded within the process of care, and with the exception of laboratory staff, clinicians working with patients do not need to interact with them. For the ordering clinician, the system prints a report with a diagnostic hypothesis for consideration, but does not remove responsibility for information gathering, examination, assessment and treatment. For the pathologist, the system cuts down the workload of generating reports, without removing the need to check and correct reports.

All scientists are familiar with the statistical approach to data analysis. Given a particular hypothesis, statistical tests are applied to data to see if any relationships can be found between different parameters. Machine learning systems can go much further. They look at raw data and then attempt to hypothesise relationships within the data, and newer learning systems are able to produce quite complex characterisations of those relationships. In other words they attempt to discover humanly understandable concepts.

Learning techniques include neural networks, but encompass a large variety of other methods as well, each with their own particular characteristic benefits and difficulties. For example, some systems are able to learn decision trees from examples taken from data (Quinlan, 1986). These trees look much like the classification hierarchies discussed in Chapter 10, and can be used to help in diagnosis.

Medicine has formed a rich test-bed for machine learning experiments in the past, allowing scientists to develop complex and powerful learning systems. While there has been much practical use of expert systems in routine clinical settings, at present machine learning systems still seem to be used in a more experimental way. There are, however, many situations in which they can make a significant contribution.

Artificial Intelligence (AI) is a field that develops intelligent algorithms and machines. Examples include: self-driving cars, smart cameras, surveillance systems, robotic manufacturing, machine translations, internet searches, and product recommendations. Modern AI often involves self-learning systems that are trained on massive amounts of data ("Big Data"), and/or interacting intelligent agents that perform distributed reasoning and computation. AI connects sensors with algorithms and human-computer interfaces, and extends itself into large networks of devices. AI has found numerous applications in industry, government and society, and is one of the driving forces of today's economy.

The Master's programme in Amsterdam has a technical approach towards AI research. It is a joint programme of the University of Amsterdam and VrijeUniversiteit Amsterdam. This collaboration guarantees a wide range of topics, all taught by world renownedresearchers who are experts in their field.
