We have designed a flexible simulation system that can support the implementation of a wide range of neural network approaches. The UCLA-SFINX simulator is especially suited for the exploration of structured, irregular, and layered connectivity patterns. Func tions, such as those in early vision, are modeled using the regular connectivity of center\/surround antagonistic receptive fields and can be implemented as the difference of concentric gaussians. Higher level cognitive functions, such as supervised and unsuper vised learning, have more irregular, dynamic connectivity structures and update mechanisms that are also supported. To visualize weight spaces, input\/output training sets, image data, or other network characteristics, SFINX provides an X- windows based graphical output that assists in rapidly assessing the consequences of altering connectivity patterns, parameter tuning, and other experiments. <\/jats:p>","DOI":"10.1177\/003754979205900502","type":"journal-article","created":{"date-parts":[[2008,3,29]],"date-time":"2008-03-29T17:23:43Z","timestamp":1206811423000},"page":"286-299","source":"Crossref","is-referenced-by-count":2,"title":["A general purpose simulation environment for neural models"],"prefix":"10.1177","volume":"59","author":[{"given":"E.","family":"Mesrobian","sequence":"first","affiliation":[{"name":"Machine Perception Laboratory Computer Science Department University of California Los Angeles Los Angeles, California 90024"}]},{"given":"J.","family":"Skrzypek","sequence":"additional","affiliation":[{"name":"Machine Perception Laboratory Computer Science Department University of California Los Angeles Los Angeles, California 90024"}]}],"member":"179","published-online":{"date-parts":[[1992,11,1]]},"reference":[{"volume-title":"Proceedings of SPIE Conference on Image Understanding and the Man-Machine Interface","author":"J.
