Research in Neural modeling of cognitive and language processes.
Jim Anderson's research concentrates on applications of neural networks
to Cognitive Science. An appropriately designed network can do many pattern
recognition functions in ways reminiscent of human performance. Neural
networks have practical applications and can also serve as models for human
behavior.
His group does research in several areas. Networks have been applied
to models of human concept formation, to speech perception, and to models
of low level vision, for example, the way local motion signals can be integrated
to determine global object motion or the direction of self motion. A current
project involves the study of elementary arithmetic, a problem that is
surprisingly hard for both humans and neural networks. Study of elementary
mathematics also raises questions about the way a neural network can be
designed to perform effectively more general mathematical operations.
Output of a neural network simulation of category formation.
Recent work has considered how intermediate level structure in the nervous
system might be configured, and how it might be detected in experimental
data, as well as what kind of computations it might perform. A model using
a network of local networks is being studied, in light of data from both
multiple unit recordings and functional MRI.
