Research and scholarship

Conceptual design of technical systems, in particular biologically inspired engineering, provides one context for Goel's problem-driven research into cognitive systems. He has developed a theory of Structure-Behavior-Function models for understanding conceptual designs [4] [5] and a theory of model-based analogical reasoning for understanding the processes of biologically inspired design. [6] [7] In addition to information-processing theories of conceptual design, [8] [9] he has built computational tools (such as the Design by Analogy to Nature Engine) for supporting its practice. [10] [11] His 2012 TEDx talk Does Our Future Require Us To Go Back to Nature? summarizes this research. [12] In 2014, he co-edited Biologically inspired design: Computational methods and tools [13] published by Springer-Verlag. During 2008–18, Ashok was a co-director of Georgia Tech's Center of Biologically Inspired Design, and during 2012-17 he served on the Board of Directors of The Biomimicry Institute including as the President of the Board during 2015–17.[ citation needed ]

Learning about complex systems and systems thinking provides another context for Goel's use-inspired cognitive systems research. He has used Structure-Behavior-Function modeling to develop a series of interactive environments for supporting learning about complex systems [14] [15] resulting in the recent web-based virtual experimentation research assistant (VERA). Smithsonian Institution's Encyclopedia of Life's webportal provides direct access to VERA to support learning about ecological systems and the scientific way of systems thinking. [16] Since 2015, Ashok has been a Faculty Fellow of the Brook Byers Institute for Sustainable Systems.

Teaching and scholarship

During 2012–2019, Ashok was the Director of Georgia Tech's Ph.D. Program in Human-Centered Computing. Since 2019, he has been the Chief Scientist with the Georgia Tech's Center for 21st Century Universities, where he leads research on AI in education and education in AI. In 2014, Goel developed an online course on Knowledge-Based AI as part of Georgia Tech's Online Master of Science in Computer Science program. [17] In 2016, he developed Jill Watson, a virtual teaching assistant for automatically answering students’ questions in discussion forums of online classes based on the IBM Watson technology. His 2016 TEDx talk A Teaching Assistant named Jill Watson describes this experiment. [18] In 2019, he co-edited Blended learning in practice: A guide for researchers and practitioners [19] published by the MIT Press. He received AAAI's Outstanding AI Educator Award in 2019 and the University System of Georgia Regent's Award for Scholarship of Teaching and Learning in 2020. Since 2021, Ashok has been the Executive Director for NSF's National AI Institute for Adult Learning and Online Education (AI-ALOE). He was selected as an AAAI Fellow in 2021 and a Cognitive Science Society Fellow in 2022. Ashok was awarded the AAAI Distinguished Service Award in 2024.

Goel's teaching and research have been covered in The Wall Street Journal , [20] The Washington Post , [21] Wired , [22] and EdTech [23] among other media. A review article in a special issue of The Chronicle of Higher Education called virtual assistants exemplified by Jill Watson as one of the most transformative educational technologies in the digital era.

Bio-inspired computing, short for biologically inspired computing, is a field of study which seeks to solve computer science problems using models of biology. It relates to connectionism, social behavior, and emergence. Within computer science, bio-inspired computing relates to artificial intelligence and machine learning. Bio-inspired computing is a major subset of natural computation.

The Association for the Advancement of Artificial Intelligence (AAAI) is an international scientific society devoted to promote research in, and responsible use of, artificial intelligence. AAAI also aims to increase public understanding of artificial intelligence (AI), improve the teaching and training of AI practitioners, and provide guidance for research planners and funders concerning the importance and potential of current AI developments and future directions.

Roger Carl Schank was an American artificial intelligence theorist, cognitive psychologist, learning scientist, educational reformer, and entrepreneur. Beginning in the late 1960s, he pioneered conceptual dependency theory and case-based reasoning, both of which challenged cognitivist views of memory and reasoning. He began his career teaching at Yale University and Stanford University. In 1989, Schank was granted $30 million in a ten-year commitment to his research and development by Andersen Consulting, through which he founded the Institute for the Learning Sciences (ILS) at Northwestern University in Chicago.

The Conference and Workshop on Neural Information Processing Systems is a machine learning and computational neuroscience conference held every December. The conference is currently a double-track meeting that includes invited talks as well as oral and poster presentations of refereed papers, followed by parallel-track workshops that up to 2013 were held at ski resorts.

A cognitive architecture refers to both a theory about the structure of the human mind and to a computational instantiation of such a theory used in the fields of artificial intelligence (AI) and computational cognitive science. The formalized models can be used to further refine a comprehensive theory of cognition and as a useful artificial intelligence program. Successful cognitive architectures include ACT-R and SOAR. The research on cognitive architectures as software instantiation of cognitive theories was initiated by Allen Newell in 1990.

The cognitive revolution was an intellectual movement that began in the 1950s as an interdisciplinary study of the mind and its processes, from which emerged a new field known as cognitive science. The preexisting relevant fields were psychology, linguistics, computer science, anthropology, neuroscience, and philosophy. The approaches used were developed within the then-nascent fields of artificial intelligence, computer science, and neuroscience. In the 1960s, the Harvard Center for Cognitive Studies and the Center for Human Information Processing at the University of California, San Diego were influential in developing the academic study of cognitive science. By the early 1970s, the cognitive movement had surpassed behaviorism as a psychological paradigm. Furthermore, by the early 1980s the cognitive approach had become the dominant line of research inquiry across most branches in the field of psychology.

The LIDA cognitive architecture is an integrated artificial cognitive system that attempts to model a broad spectrum of cognition in biological systems, from low-level perception/action to high-level reasoning. Developed primarily by Stan Franklin and colleagues at the University of Memphis, the LIDA architecture is empirically grounded in cognitive science and cognitive neuroscience. In addition to providing hypotheses to guide further research, the architecture can support control structures for software agents and robots. Providing plausible explanations for many cognitive processes, the LIDA conceptual model is also intended as a tool with which to think about how minds work.
