Computational Cognition
Our most recent project has been the development of the Hyperspace Analogue to
Language (or HAL) which is a computer simulation of human memory. HAL has a
lexicon of 70,000 items and learns its representations as a function of the
contexts in which words occur. This is accomplished with a concept-acquisition
process that requires no supervision using an input of 300 million words of text.
Word meanings (broadly based) are represented in 140,000 dimensional space (thus,
Hyperspace Analogue to Language). The model accounts for a wide range of semantic,
language, grammatical, and syntactic phenomena.
See the lab research page for abstracts on this work and our connectionist
modeling work on parsing.
