Extending SME to Handle Large‐Scale Cognitive Modeling

Abstract

Theory of Mind (ToM) has been well studied in psychology. It is what gives adults the ability to predict other people's beliefs, desires, and related actions. When ToM is not yet developed, as in young children, social interaction is difficult. A cognitive system that interacts with humans on a regular basis would benefit from having a ToM. In this extended abstract, I propose a computational model of ToM, Analogical Theory of Mind (AToM), based on Bach's [2012, 2014] theoretical Structure-Mapping model of ToM. Completed work demonstrates the plausibility of AToM. Future steps include a full implementation and test of AToM.

AToM: An Analogical Theory of Mind

“…AToM is based on the Structure-Mapping Theory of ToM proposed by Bach [2011Bach [ , 2014. It is built on top of the Structure-Mapping Engine [SME, Forbus et al 2016], a computational model of SMT; the SAGE model of analogical generalization [McLure et al 2010]; and the MAC/FAC model of analogical retrieval [Forbus et al 1995].…”

“…It is built on top of the Structure-Mapping Engine [SME, Forbus et al 2016], a computational model of SMT; the SAGE model of analogical generalization [McLure et al 2010]; and the MAC/FAC model of analogical retrieval [Forbus et al 1995]. AToM assumes a long term memory (LTM) of predicate calculus cases that can be retrieved via MAC/FAC.…”

“…When complete, AToM will be integrated into the Companion cognitive architecture [Forbus et al 2009]. This will enhance a Companion's interactive abilities.…”

“…In fact, it has been suggested that our need for social interaction is responsible for our large brains and incredible language abilities [e.g. Reader and Laland, 2002]. If artificial intelligence systems are to be integrated into our society, then they, too, must have the social capabilities available to us.…”

“…While some evidence of ToM exists in a other highly social animals, such as dolphins and apes [e.g. Krupenye et al 2016], the extent to which we use and rely on ToM seems to be uniquely human.…”
