To the Editors: Baxt's (1) successful use of neural networks in accurately diagnosing myocardial infarction in an emergency room setting illustrates the vast potential utility of this technique for medical decision making. Unfortunately, despite an apparently straightforward mathematical foundation, much of the design and training of neural networks remains an intuitive art. Network theory provides very little guidance for optimizing network structure, including optimizing the depth of hidden layers and the number of nodes in those layers, which are important determinants of computing resources necessary for training the network (2). Such considerations are paramount in large input nets and in
