[R] R-help: need help in obtaining training data and predictions for neural networks

2011-07-08 Thread Hafsa Hassan
Dear list, I am new to R and am using it to develop and test my own neural network codes. I need some training datasets that have the prediction results that should (approximately) appear when the datasets are passed through a good neural network, in order to test whether my code is working ac

2011-06-30 Thread Hafsa Hassan
Dear list, I am new to programming in R, and am implementing my own neural network code and trying to compare its output with that of nnet(). I have tried the nnet CRAN help package, google and R-help mailing list to find out what the nnet() output means, and what the training algorithm is, but ha

Greetings list, I am new to programming in R, and am using nnet() function for a project on neural networking. Firslty i widh to ask if there is any pdf explaining the algorithm nnet uses, which could tell me what the objects of the nnet class, like 'conn', 'nconn, 'nsunits', n and 'nunits' mean,
