Review: Reflections on Abstractions for General Artificial Intelligence

Newell (1990) Unified Theories of Cognition

Newell (1990)

Initially, when I first read the abstract of Laird’s article I was turn off, mostly because he cites Newell (1990) – it just seems so old school.

It’s been almost 25 years since Newell’s Unified Theories of Cognition, but I’m glad I continued reading because there is much I like about this short article.

When I first got into AI, I was kind of obsessed with symbolic cognitive architectures, thinking they had much potential to achieve General Artificial Intelligence. But the more I researched the more I realized how much cognitive architectures:

a) neglected the mind, body, environment model

b) focused too much on high level cognitive functions, like language

With respect to “a”, I believe, an ecological approach to AI is paramount. That is, we should be focusing our research on perception and action.

With respect to “b”, it seems like symbolic cognitive architectures were trying to solve high level functions when they haven’t solved low level functions, ie. perception and action.

The Virtual Autonomous Learner: An Introduction

virtual autonomous learner

This post, an introduction to my thesis topic, a virtual autonomous learner or VAL for short, is aimed at a general audience. Though, I am sure anyone with research interest in: evolution, ecology, artificial intelligence, neuroscience, artificial neural networks, education, virtual simulation, computation, and all things related to the body and the mind, especially embodied cognition, would find this post interesting.

For those of you with short attention spans like myself, I offer you this quick and simple explanation of what VAL is:

virtual autonomous learner = artificial intelligence.

Simple, right? However, if you stick around I will explain why this equation is not really true. And, in fact, VAL is not AI – it’s something new.

A Cognitive Architecture Primer

Saturday, October 9th, 2010

Cognitive ArchitectureThe expression cognitive architecture, like the name implies, is an architecture of cognition. Cognition, in this context, refers to any thought process (i.e., perception, memory, learning or language). Architecture, also in this context, can be seen as a computational blueprint or computation model, the blueprint being a diagram which lays out the framework of computational construction (set of rules to follow). Basically, a blueprint gives all the information one needs in order to build the structure, in this case a cognitive task. In this sense, a cognitive architecture is a metaphorical blueprint that illustrates the essential structures and relationships of different components that make up how we think. Hence, for the purpose of this post, a cognitive architecture is any theoretical or practical system that attempts to explain or simulate the broad range of human thought processes.

The Inception of the Virtual Autonomous Learner (VAL)

Thursday, September 30th, 2010

Inception of VALThe inception of VAL was conceived in an advanced reading class where I studied the current state of artificial intelligence (AI). The background research involved in this project was heavily interdisciplinary. Some of the major research areas were evolution, evolutionary psychology, experimental psychology, neurology, ecology, learning theories, educational technologies, computation, simulation, computational neural modeling, early child development, cognition, linguistics, computer science, and philosophies like Theory of Mind. Much of my research led to experimental psychology and the field of computational neural modeling and cognitive architectures.

In the beginning, I was overwhelmed and astonished with the variety of cognitive architectures that were currently being developed within reputable institutions1.
