The exact and comprehensive QSAN study is the key to finding new compoundswith high activity. Artificial neural networks (ANNs) are a newly emerging field ofinformation processing technology. As ANNs can be taught complex nonlinearinput-output transformations and have the ability of adaptive learning, resistance tonoise and fault tolerance, they can solve the pattern recognition and funtionalmapping problems.展开更多
