Regarding the temporal requirements of a hierarchical Willshaw network
2012
Neural Networks
Preserved Fulltext
In a recent communication, Sacramento and Wichert (2011) proposed a hierarchical retrieval prescription for Willshaw-type associative networks. ...
Through simulation it was shown that one could make use of low resolution descriptor patterns to decrease the total time requirements of recalling a learnt association. ...
Acknowledgments The authors are indebted to an anonymous reviewer which contributed with many detailed comments, including an improved asymptotic bound f (n) on a, and to Ângelo Cardoso and Francisco S ...

Mathematical modeling of anatomically-constrained neural networks has provided significant insights regarding the response of networks to neurological disorders or injury. ...
A logical extension of these models is to incorporate treatment regimens to investigate network responses to intervention. ...
Due to the hierarchical nature of the cerebral cortex, its development and reorganization following injury have been significant targets for modeling studies (Willshaw and von der Malsburg, 1976; Armentrout ...
