====== TRIANGLE AREA NEURAL NETWORK INTEREST GROUP presents: ====== Prof. DANIEL S. LEVINE Department of Mathematics University of Texas at Arlington Tuesday, April 2, 1991 5:30 p.m. Refreshments will be served at 5:15. Sitterson Hall (Computer Science), room 011 UNC Chapel Hill ---------------------------------------------------------------------- NETWORK MODELING OF NEUROPSYCHOLOGICAL DATA A general class of neural network architectures will be discussed, based on such principles as associative learning, competition, and opponent processing. Examples of this sort of architecture will be introduced that model data on neuropsychological deficits arising from frontal lobe damage. These deficits include inability to switch criteria on a card sorting task; excessive attraction to novel stimuli; loss of verbal fluency; and difficulty in learning a flexible motor sequence. Frontal lobe damage is modeled in these networks by weakening of a specified connection. Dan Levine is author of the forthcoming textbook Introduction to Neural and Cognitive Modeling, published by L. Erlbaum Associates, 1991. He is a co-founder of the Dallas-Ft.Worth area neural network interest group M.I.N.D. ---------------------------------------------------------------------- Co-Sponsored by: Department of Electrical and Computer Eng., NCSU Department of Computer Science, UNC-CH Humanities Computing Facility, Duke Univ. Directions: Sitterson Hall is located across the street from the Carolina Inn, on South Columbia Street (Route 86), which is the main north-south street through downtown Chapel Hill. Free parking is available in the UNC lots, two of which are adjacent to Sitterson Hall. Municipal parking lots are located 2-3 blocks north, in downtown Chapel Hill. ---------------------------------------------------------------------- We invite you to participate in organizing and running the new Triangle-area neural network (NN) interest group. It is our hope that the group will foster communication and collaboration among the local NN researchers, students, businesses, and the public.
