615. PSDD: Perceptron-Type Neural Network Simulator
by Hiroshi Ichikawa, Hoshi College of Pharmacy, 2-4-41
Ebara, Shinagawa, Tokyo 142, Japan
PSDD stands for Perceptron Simulator for Drug Design, a
hierarchical neural network simulator which the author
has developed for drug design. The program, however,
may apply to many other problems in many other fields
as a nonlinear classifier or a nonlinear
multiregression analyzer.
PSDD includes the options of the reconstruction-
learning technique, leave-one-out experiment and
partial derivative calculation of each output strength
with respect to each input parameter in addition to the
usual classification, fitting and prediction
operations. The network structure can be freely
changed by setting network parameters.
