Artificial Intelligence - What Were The Macy Conferences?


The Macy Conferences on Cybernetics, which ran from 1946 to 1960, aimed to provide the framework for developing multidisciplinary disciplines such as cybernetics, cognitive psychology, artificial life, and artificial intelligence.

Famous twentieth-century scholars, academics, and researchers took part in the Macy Conferences' freewheeling debates, including psychiatrist W.

Ross Ashby, anthropologist Gregory Bateson, ecologist G. Evelyn Hutchinson, psychologist Kurt Lewin, philosopher Donald Marquis, neurophysiologist Warren McCulloch, cultural anthropologist Margaret Mead, economist Oskar Morgenstern, statistician Leonard Savage, physicist Heinz von Foerster McCulloch, a neurophysiologist at the Massachusetts Institute of Technology's Research Laboratory for Electronics, and von Foerster, a professor of signal engineering at the University of Illinois at Urbana-Champaign and coeditor with Mead of the published Macy Conference proceedings, were the two main organizers of the conferences.

All meetings were sponsored by the Josiah Macy Jr. Foundation, a nonprofit organization.

The conferences were started by Macy administrators Frank Fremont-Smith and Lawrence K. Frank, who believed that they would spark multidisciplinary discussion.

The disciplinary isolation of medical research was a major worry for Fremont-Smith and Frank.

A Macy-sponsored symposium on Cerebral Inhibitions in 1942 preceded the Macy meetings, during which Harvard physiology professor Arturo Rosenblueth presented the first public discussion on cybernetics, titled "Behavior, Purpose, and Teleology." The 10 conferences conducted between 1946 and 1953 focused on biological and social systems' circular causation and feedback processes.

Between 1954 and 1960, five transdisciplinary Group Processes Conferences were held as a result of these sessions.

To foster direct conversation amongst participants, conference organizers avoided formal papers in favor of informal presentations.

The significance of control, communication, and feedback systems in the human nervous system was stressed in the early Macy Conferences.

The contrasts between analog and digital processing, switching circuit design and Boolean logic, game theory, servomechanisms, and communication theory were among the other subjects explored.

These concerns belong under the umbrella of "first-order cybernetics." Several biological issues were also discussed during the conferences, including adrenal cortex function, consciousness, aging, metabolism, nerve impulses, and homeostasis.

The sessions acted as a forum for discussing long-standing issues in what would eventually be referred to as artificial intelligence.

(At Dartmouth College in 1955, mathematician John McCarthy invented the phrase "artificial intelligence.") Gregory Bateson, for example, gave a lecture at the inaugural Macy Conference that differentiated between "learning" and "learning to learn" based on his anthropological research and encouraged listeners to consider how a computer might execute either job.

Attendees in the eighth conference discussed decision theory research, which was led by Leonard Savage.

Ross Ashby suggested the notion of chess-playing automatons at the ninth conference.

The usefulness of automated computers as logic models for human cognition was discussed more than any other issue during the Macy Conferences.

In 1964, the Macy Conferences gave rise to the American Society for Cybernetics, a professional organization.

The Macy Conferences' early arguments on feedback methods were applied to topics as varied as artillery control, project management, and marital therapy.

Artificial Intelligence - What Is The Dartmouth AI Conference?


    The Dartmouth Conference on Artificial Intelligence, officially known as the "Dartmouth Summer Research Project on Artificial Intelligence," was held in 1956 and is frequently referred to as the AI Constitution.

    • The multidisciplinary conference, held on the Dartmouth College campus in Hanover, New Hampshire, brought together specialists in cybernetics, automata and information theory, operations research, and game theory.
    • Claude Shannon (the "father of information theory"), Marvin Minsky, John McCarthy, Herbert Simon, Allen Newell ("founding fathers of artificial intelligence"), and Nathaniel Rochester (architect of IBM's first commercial scientific mainframe computer) were among the more than twenty attendees.
    • Participants came from the MIT Lincoln Laboratory, Bell Laboratories, and the RAND Systems Research Laboratory.

    The Rockefeller Foundation provided a substantial portion of the funding for the Dartmouth Conference.

    The Dartmouth Conference, which lasted around two months, was envisaged by the organizers as a method to make quick progress on computer models of human cognition.

    • "Every facet of learning or any other trait of intelligence may in theory be so clearly characterized that a computer can be constructed to replicate it," organizers said as a starting point for their deliberations (McCarthy 1955, 2).

    • In his Rockefeller Foundation proposal a year before to the summer meeting, mathematician and principal organizer John McCarthy created the phrase "artificial intelligence." McCarthy subsequently said that the new name was intended to establish a barrier between his study and the discipline of cybernetics.
    • He was a driving force behind the development of symbol processing techniques to artificial intelligence, which were at the time in the minority.
    • In the 1950s, analog cybernetic techniques and neural networks were the most common brain modeling methodologies.

    Issues Covered At The Conference.

    The Dartmouth Conference included a broad variety of issues, from complexity theory and neuron nets to creative thinking and unpredictability.

    • The conference is notable for being the site of the first public demonstration of Newell, Simon, and Clifford Shaw's Logic Theorist, a program that could independently verify theorems stated in Bertrand Russell and Alfred North Whitehead's Principia Mathematica.
    • The only program at the conference that tried to imitate the logical features of human intellect was Logic Theorist.
    • Attendees predicted that by 1970, digital computers would have become chess grandmasters, discovered new and important mathematical theorems, produced passable language translations and understood spoken language, and composed classical music.
    • Because the Rockefeller Foundation never received a formal report on the conference, the majority of information on the events comes from memories, handwritten notes, and a few papers authored by participants and published elsewhere.

    Mechanization of Thought Processes

    Following the Dartmouth Conference, the British National Physical Laboratory (NPL) hosted an international conference on "Mechanization of Thought Processes" in 1958.

    • Several Dartmouth Conference attendees, including Minsky and McCarthy, spoke at the NPL conference.
    • Minsky mentioned the Dartmouth Conference's relevance in the creation of his heuristic software for solving plane geometry issues and the switch from analog feedback, neural networks, and brain modeling to symbolic AI techniques at the NPL conference.
    • Neural networks did not resurface as a research topic until the mid-1980s.

    Dartmouth Summer Research Project 

    The Dartmouth Summer Research Project on Artificial Intelligence was a watershed moment in the development of AI. 

    The Dartmouth Summer Research Project on Artificial Intelligence, which began in 1956, brought together a small group of scientists to kick off this area of study. 

    To mark the occasion, more than 100 researchers and academics gathered at Dartmouth for AI@50, a conference that celebrated the past, appraised current achievements, and helped seed ideas for future artificial intelligence research. 

    John McCarthy, then a mathematics professor at the College, convened the first gathering. 

    The meeting would "continue on the basis of the premise that any facet of learning or any other attribute of intelligence may in theory be so clearly characterized that a computer can be constructed to replicate it," according to his plan. 

    The director of AI@50, Professor of Philosophy James Moor, explains that the researchers who came to Hanover 50 years ago were thinking about methods to make robots more aware and sought to set out a framework to better comprehend human intelligence.

    Context Of The Dartmouth AI Conference:

    Cybernetics, automata theory, and sophisticated information processing were all terms used in the early 50s to describe the science of "thinking machines." 

    The wide range of names reflects the wide range of intellectual approaches. 

    In, John McCarthy, a Dartmouth College Assistant Professor of Mathematics, wanted to form a group to clarify and develop ideas regarding thinking machines. 

    • For the new field, he chose the moniker 'Artificial Intelligence.' He picked the term mainly to escape a concentration on limited automata theory and cybernetics, which was largely focused on analog feedback, as well as the possibility of having to accept or dispute with the aggressive Norbert Wiener as guru. 
    • McCarthy addressed the Rockefeller Foundation in early to seek money for a summer seminar at Dartmouth that would attract roughly 150 people. 
    • In June, he and Claude Shannon, then at Bell Labs, met with Robert Morison, Director of Biological and Medical Research, to explore the concept and potential financing, but Morison was skeptical if money would be made available for such a bold initiative. 

    McCarthy, Marvin Minsky, Nathaniel Rochester, and Claude Shannon officially proposed the proposal in September. The term "artificial intelligence" was coined as a result of this suggestion. 

    According to the proposal, 

    • We suggest that during the summer of at Dartmouth College in Hanover, New Hampshire, a -month, -man artificial intelligence research be conducted. 
    • The research will be based on the hypothesis that any part of learning, or any other characteristic of intelligence, can be characterized exactly enough for a computer to imitate it. 
    • It will be attempted to figure out how to get robots to speak, develop abstractions and ideas, solve issues that are now reserved for people, and improve themselves. 
    • We believe that if a properly chosen group of scientists worked on one or more of these topics together for a summer, considerable progress might be accomplished. 
    • Computers, natural language processing, neural networks, theory of computing, abstraction, and creativity are all discussed further in the proposal (these areas within the field of artificial intelligence are considered still relevant to the work of the field). 

    He remarked, "We'll focus on the difficulty of figuring out how to program a calculator to construct notions and generalizations. 

    Of course, this is subject to change once the group meets." Ray Solomonoff, Oliver Selfridge, Trenchard More, Arthur Samuel, Herbert A. Simon, and Allen Newell were among the participants at the meeting, according to Stottler Henke Associates. 

    The real participants arrived at various times, most of which were for far shorter periods of time. 

    • Rochester was replaced for three weeks by Trenchard More, and MacKay and Holland were unable to attend—but the project was prepared to commence. 
    • Around June of that year, the first participants (perhaps simply Ray Solomonoff, maybe with Tom Etter) came to Dartmouth College in Hanover, New Hampshire, to join John McCarthy, who had already set up residence there. 
    • Ray and Marvin remained at the Professors' apartments, while the most of the guests stayed at the Hanover Inn.

    Artificial Intelligence - How Is AI Contributing To Cybernetics?


    The study of communication and control in live creatures and machines is known as cybernetics.

    Although the phrase "cybernetic thinking" is no longer generally used in the United States, it pervades computer science, engineering, biology, and the social sciences today.

    Throughout the last half-century, cybernetic connectionist and artificial neural network approaches to information theory and technology have often clashed, and in some cases hybridized, with symbolic AI methods.

    Norbert Wiener (1894–1964), who coined the term "cybernetics" from the Greek word for "steersman," saw the field as a unifying force that brought disparate topics like game theory, operations research, theory of automata, logic, and information theory together and elevated them.

    Winer argued in Cybernetics, or Control and Communication in the Animal and the Machine (1948), that contemporary science had become too much of a specialist's playground as a consequence of tendencies dating back to the early Enlightenment.

    Wiener envisioned a period when experts might collaborate "not as minions of some great administrative officer, but united by the desire, indeed by the spiritual imperative, to comprehend the area as a whole, and to give one another the power of that knowledge" (Weiner 1948b, 3).

    For Wiener, cybernetics provided researchers with access to many sources of knowledge while maintaining their independence and unbiased detachment.

    Wiener also believed that man and machine should be seen as basically interchangeable epistemologically.

    The biological sciences and medicine, according to Wiener, would remain semi-exact and dependent on observer subjectivity until these common components were discovered.

    In the setting of World War II (1939– 1945), Wiener developed his cybernetic theory.

    Operations research and game theory, for example, are interdisciplinary sciences rich in mathematics that have previously been utilized to identify German submarines and create the best feasible solutions to complex military decision-making challenges.

    Wiener committed himself into the job of implementing modern cybernetic weapons against the Axis countries in his role as a military adviser.

    To that purpose, Wiener focused on deciphering the feedback processes involved in curvilinear flight prediction and applying these concepts to the development of advanced fire-control systems for shooting down enemy aircraft.

    Claude Shannon, a long-serving Bell Labs researcher, went even further than Wiener in attempting to bring cybernetic ideas to life, most notably in his experiments with Theseus, an electromechanical mouse that used digital relays and a feedback process to learn how to navigate mazes based on previous experience.

    Shannon created a slew of other automata that mimicked the behavior of thinking machines.

    Shannon's mentees, including AI pioneers John McCarthy and Marvin Minsky, followed in his footsteps and labeled him a symbolic information processor.

    McCarthy, who is often regarded with establishing the field of artificial intelligence, studied the mathematical logic that underpins human thought.

    Minsky opted to research neural network models as a machine imitation of human vision.

    The so-called McCulloch-Pitts neurons were the core components of cybernetic understanding of human cognitive processing.

    These neurons were strung together by axons for communication, establishing a cybernated system encompassing a crude simulation of the wet science of the brain, and were named after Warren McCulloch and Walter Pitts.

    Pitts admired Wiener's straightforward analogy of cerebral tissue to vacuum tube technology, and saw these switching devices as metallic analogues to organic cognitive components.

    McCulloch-Pitts neurons were believed to be capable of mimicking basic logical processes required for learning and memory.

    Pitts perceived a close binary equivalence between the electrical discharges produced by these devices and the electrochemical nerve impulses generated in the brain in the 1940s.

    McCulloch-Pitts inputs may be either a zero or a one, and the output can also be a zero or a one in their most basic form.

    Each input may be categorized as excitatory or inhibitory.

    It was therefore merely a short step from artificial to animal memory for Pitts and Wiener.

    Donald Hebb, a Canadian neuropsychologist, made even more significant contributions to the research of artificial neurons.

    These were detailed in his book The Organization of Behavior, published in 1949.

    Associative learning is explained by Hebbian theory as a process of neural synaptic cells firing and connecting together.

    In his study of the artificial "perceptron," a model and algorithm that weighted inputs so that it could be taught to detect particular kinds of patterns, U.S.

    Navy researcher Frank Rosenblatt expanded the metaphor.

    The eye and cerebral circuitry of the perceptron could approximately discern between pictures of cats and dogs.

    The navy saw the perceptron as "the embryo of an electronic computer that it anticipates to be able to walk, speak, see, write, reproduce itself, and be cognizant of its existence," according to a 1958 interview with Rosenblatt (New York Times, July 8, 1958, 25).

    Wiener, Shannon, McCulloch, Pitts, and other cyberneticists were nourished by the famed Macy Conferences on Cybernetics in the 1940s and 1950s, which attempted to automate human comprehension of the world and the learning process.

    The gatherings also acted as a forum for discussing artificial intelligence issues.

    The divide between the areas developed over time, but it was visible during the 1956 Dartmouth Summer Research Project on ArtificialIntelligence.

    Organic cybernetics research was no longer well-defined in American scientific practice by 1970.

    Computing sciences and technology evolved from machine cybernetics.

    Cybernetic theories are now on the periphery of social and hard scientific disciplines such as cognitive science, complex systems, robotics, systems theory, and computer science, but they were critical to the information revolution of the twentieth and twenty-first centuries.

    In recent studies of artificial neural networks and unsupervised machine learning, Hebbian theory has seen a resurgence of attention.

    Cyborgs—beings made up of biological and mechanical pieces that augment normal functions—could be regarded a subset of cybernetics (which was once known as "medical cybernetics" in the 1960s).

    Artificial Intelligence - AI Revolution In Cognitive Psychology.

    In the late 1950s, a paradigm-shattering movement known as the "Cognitive Revolution" saw American experimental psychologists break away from behaviorism—the theory that "training" explains human and animal behavior.

    This means adopting a computational or information-processing theory of mind in psychology.

    Task performance, according to cognitive psychology, requires decision-making and problem-solving procedures based on stored and immediate perception, as well as conceptual knowledge.

    In meaning-making activities, signs and symbols encoded in the human nervous system from contacts in the environment are stored in internal memory and matched against future events.

    Humans are skilled in seeking and finding patterns, according to this viewpoint.

    Every detail of a person's life is stored in their memory.

    Recognition is the process of matching current perceptions with previously stored information representations.

    From about the 1920s through the 1950s, behaviorism dominated mainstream American psychology.

    The hypothesis proposed that learning of connections via conditioning, which involves inputs and reactions rather than thoughts or emotions, could explain most human and animal behavior.

    Under behaviorism, it was assumed that the best way to treat disorders was to change one's behavior patterns.

    The new ideas and theories that challenged the behaviorist viewpoint originated mostly from outside of psychology.

    Signal processing and communications research, notably the "information theory" work of Claude Shannon at Bell Labs in the 1940s, had major effect on the discipline.

    Shannon claimed that information flow may be used to describe human vision and memory.

    In this approach, cognition may be seen as an information processing phenomena.

    Donald Broadbent, who wrote in Perception and Communication (1958) that humans have a limited capacity to process an overwhelming amount of available information and thus must apply a selective filter to received stimuli, was one of the first proponents of a psychological theory of information processing.

    Short-term memory receives the information that goes through the filter, which is then altered before being transmitted and stored in long-term memory.

    His model's analogies are mechanical rather than behavioral.

    Other psychologists, particularly mathematical psychologists, were inspired by this idea, believing that quantifying information in bits may assist quantify the science of memory.

    Psychologists were also influenced by the invention of the digital computer in the 1940s.

    Soon after WWII ended, critics and scientists alike began equating computers to human intelligence, with mathematicians Edmund Berkeley, author of Giant Brains, or Machines That Think (1949), and Alan Turing, in his article "Computing Machinery and Intelligence," being the most prominent (1950).

    Early artificial intelligence researchers like Allen Newell and Herbert Simon were motivated by works like these to develop computer systems that could solve problems in a human-like manner.

    Mental representations might be treated as data structures, and human information processing as programming, according to computer modeling.

    These concepts may still be found in cognitive psychology.

    A third source of ideas for cognitive psychology comes from linguistics, namely Noam Chomsky's generative linguistics method.

    Syntactic Structures, published in 1957, explained the mental structures required to support and express the information that language speakers must possess.

    To turn one syntactic structure into another, he proposed that transformational grammar components be included.

    In 1959, Chomsky authored a critique of B. F. Skinner's book Verbal Behavior, which is credited with destroying behaviorism as a serious scientific approach to psychology.

    In psychology, Jerome Bruner, Jacqueline Goodnow, and George Austin created the notion of concept attainment in their book A Study of Thinking (1956), which was especially well suited to the information processing approach to psychology.

    They finally agreed that concept learning included "the search for and cataloguing of traits that may be utilized to differentiate exemplars from non-exemplars of distinct categories" (Bruner et al. 1967).

    Under the guidance of Bruner and George Miller, Harvard University established a Center for Cognitive Studies in 1960, which formalized the Cognitive Revolution.

    Cognitive psychology produced significant contributions to cognitive science in the 1960s, especially in the areas of pattern recognition, attention and memory, and the psychological theory of languages (psycholinguistics).

    Pattern recognition was simplified to the perception of very simple characteristics (graphics primitives) and a matching procedure in which the primitives were matched to items stored in visual memory.

    Information processing theories of attention and memory emerged in the 1960s as well.

    The Atkinson and Shiffrin model, which developed a mathematical model of information as it moved from short-term to long-term memory, following rules for encoding, storage, and retrieval that governed the flow, is perhaps the most well-known.

    Information was characterized as being lost from storage due to interference or decay.

    Those who wished to find out how Chomsky's ideas of language worked in practice gave birth to the area of psycholinguistics.

    Psycholinguistics utilizes many of the methods of cognitive psychology.

    The use of reaction time in perceptual-motor tasks to infer the content, length, and temporal sequencing of cognitive activities is known as mental chronometry.

    Processing speed is used as a measure of processing efficiency.

    Participants in one well-known research were given questions such, "Is a robin a bird?" "Is a robin an animal?" and "Is a robin an animal?" The larger the categorical difference between the words, the longer it took the responder to react.

    The researchers demonstrated how semantic models might be hierarchical by showing how the idea robin is directly related to bird and indirectly connected to animal via the notion of bird.

    By passing through "bird," information flows from "robin" to "animal." Memory and language studies began to cross in the 1970s and 1980s, when artificial intelligence researchers and philosophers debated proposed representations of visual imagery.

    As a result, cognitive psychology has become considerably more multidisciplinary.

    In connectionism and cognitive neuroscience, two new study avenues have emerged.

    To find brain models of emergent linkages, nodes, and linked networks, connectionism combines cognitive psychology, artificial intelligence, neuroscience, and philosophy of mind.

    Connectionism (also known as "parallel distributed processing" or "neural networking") is fundamentally computational.

    Artificial neural networks are based on the perception and cognition of human brains.

    Cognitive neuroscience is a branch of study that investigates the nervous system's role in cognition.

    The areas of cognitive psychology, neurobiology, and computational neuroscience collide in this project.
