15.1. Recommended Amount of Data

Applies to: NeuralTools 5.x–7.x

I have about 700 rows of 100 columns to train my network. Is this sufficient? How can I determine in advance the number of rows necessary for a given number of columns?

There's no minimum number of columns (variables). As for the number of rows (cases), this can be determined only by experimentation: training and testing neural nets. Some authors in the literature have suggested 300 records, but that would probably apply if they had say 10 variables. With 100 variables, 300 rows would be far too few. Again, experimentation with a particular data set is the only way to determine whether you have enough cases in your data set.
