Performance of Neural Networks

Brief explanation of neural networks Four classes of innovations based on neural networks Are papers on neural networks respectable? Materials Science

Empirical Equations

noise

modelling uncertainty

elegantly answers the question as to whether sufficient data have been used to create the model unreasonable to ask if sufficient data used to create model, relative to number of coefficients - may be sufficient data in some regions of input space and not in others
