Terrence J. Sejnowski of the Salk Institute and Charles Rosenberg of Princeton University developed NETtalk, a feedforward neural network trained to convert English text to speech, publishing the principal account in Complex Systems in 1987. The network learned pronunciation from examples alone, demonstrating that a multi-layer perceptron could acquire a complex linguistic skill without hand-coded rules.
Architectures and modelsSecond AI Winter
From approximately 1987 to 1993, AI research entered a second sustained contraction as commercial expert-system vendors collapsed, the Lisp machine market failed, and DARPA substantially reduced funding for AI programmes following unmet expectations from the preceding boom.
Theory and foundationsErnst Dickmanns and VaMoRs Autonomous Van Test, Bundeswehr University Munich
In 1986, Ernst Dickmanns and colleagues at Bundeswehr University Munich demonstrated VaMoRs, a Mercedes-Benz van retrofitted with cameras and real-time computer vision, capable of autonomous driving on traffic-free roads at speeds up to approximately 96 km/h, marking one of the earliest working autonomous vehicle demonstrations.
Autonomous vehiclesW. Daniel Hillis Proposes the Connection Machine Architecture
In 1985, W. Daniel Hillis of MIT and Thinking Machines Corporation completed his doctoral dissertation introducing the Connection Machine, a massively parallel architecture connecting 65,536 single-bit processors to accelerate symbolic and artificial-intelligence computation, realised as the CM-1 system.
Compute and infrastructureWABOT-2 Humanoid Robot Demonstrated at Waseda University
In 1984, researchers at Waseda University in Japan completed WABOT-2, a humanoid robot capable of reading printed musical scores, communicating with a human performer via speech, and playing an electronic organ using its fingers and foot pedals at a level comparable to an average adult pianist.
Humanoid roboticsHAM-ANS Natural Language Dialog System (University of Hamburg, 1983)
In 1983, Wolfgang Hoeppner, Katharina Morik, and Heinz Marburger at the University of Hamburg presented HAM-ANS, a natural language dialog system enabling users to query databases in ordinary German, demonstrated at the GWAI-83 workshop and published in Springer's Lecture Notes in Computer Science series.
Language understandingPUFF expert system interprets pulmonary function tests at Stanford
In 1983, Janice S. Aikins, John C. Kunz, and Edward H. Shortliffe of Stanford University published a description of PUFF, a rule-based expert system that automated interpretation of pulmonary function test data at Pacific Medical Center in San Francisco, producing physician-reviewed diagnostic reports without manual analysis.
DiagnosisSOAR Cognitive Architecture: Doctoral Dissertations by John E. Laird and Paul S. Rosenbloom, Supervised by Allen Newell
In 1983, John E. Laird and Paul S. Rosenbloom completed doctoral dissertations at Carnegie Mellon University under Allen Newell, introducing SOAR, a cognitive architecture designed to support a broad range of intelligent tasks through a unified problem-space model and a chunking-based learning mechanism.
Architectures and modelsCADUCEUS Medical Expert System (Pople, University of Pittsburgh)
Harry Pople at the University of Pittsburgh developed CADUCEUS (originally called INTERNIST-1) during the late 1970s and early 1980s, publishing a detailed account in 1982. The system encoded diagnostic knowledge for several hundred internal medicine diseases and was among the most comprehensive medical diagnosis programs of its era.
DiagnosisINTERNIST-I Developed by Jack D. Myers and Harry E. Pople Jr.
Jack D. Myers and Harry E. Pople Jr. at the University of Pittsburgh developed INTERNIST-I, an expert system for internal medicine diagnosis, with its principal public evaluation published in the New England Journal of Medicine in 1982. The system encoded knowledge of roughly 500 diseases and 3,500 symptoms, demonstrating that algorithmic clinical reasoning could approach specialist performance on complex cases.
DiagnosisPrimal Sketch Theory of Early Visual Representation Described by David Marr
David Marr, working at MIT's Artificial Intelligence Laboratory, formalised the primal sketch as the first stage of his three-level theory of visual processing, published posthumously in 'Vision' (1982). The model proposed that the visual system constructs a symbolic, viewer-centred description of intensity changes and local geometry before any object recognition takes place.
Theory and foundationsRB5X Personal Robot Introduced by RB Robot Corporation
In 1982, RB Robot Corporation, founded by Joseph Bosworth, introduced the RB5X, a dome-shaped autonomous personal robot programmable in TinyBASIC or the proprietary Savvy language, equipped with sonar, photodiode, and bumper sensors for navigating domestic environments without direct human guidance.
Manipulation and dexterityFifth Generation Computer Systems Project, Japan
In October 1981, Japan's Ministry of International Trade and Industry launched the Fifth Generation Computer Systems project, a ten-year state-funded programme delegated to the newly created Institute for New Generation Computer Technology (ICOT), aiming to build computers capable of logical inference, natural-language processing, and machine vision, with a budget of approximately 54 billion yen.
Reasoning and planningFirst National Conference on Artificial Intelligence (AAAI-80), Stanford University
In August 1980, the Association for the Advancement of Artificial Intelligence held its first national conference (AAAI-80) at Stanford University, establishing a dedicated annual forum for AI research at a moment when the field was simultaneously attracting commercial interest and facing concerns about overextended promises.
Regulation and policyBlackboard Model Description by Lee Erman, Richard Hayes-Roth, Victor Lesser and D. Raj Reddy
In May 1980, Lee Erman, Richard Hayes-Roth, Victor Lesser and D. Raj Reddy published 'The Hearsay-II Speech-Understanding System: Integrating Knowledge to Resolve Uncertainty' in Artificial Intelligence, vol. 14, providing the canonical description of the blackboard model as a structured framework for cooperative problem-solving among independent knowledge sources.

In 1980, John Searle at the University of California, Berkeley published 'Minds, Brains, and Programs' in Behavioral and Brain Sciences, presenting the Chinese Room thought experiment to argue that executing a computer program is insufficient to produce understanding or intentionality, directly challenging claims of strong artificial intelligence.
Theory and foundationsCommercial Lisp Machine Market: Symbolics and LMI
From 1980 onwards, Symbolics Inc. and Lisp Machines Inc. (LMI), both founded as spin-offs from the MIT Artificial Intelligence Laboratory, commercialised dedicated hardware workstations designed to run Lisp natively, offering large address spaces, garbage collection in hardware, and early graphical interfaces tailored to AI development.

John P. McDermott at Carnegie Mellon University developed R1 (later named XCON), a rule-based expert system built in OPS5, in collaboration with Digital Equipment Corporation. Deployed operationally by DEC in 1980, it automatically configured VAX-11/780 computer orders, replacing a labour-intensive manual process.
