PSDD stands for Perceptron Simulator for Drug Design, a hierar achical 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. |
