Predict - Perceptron - Neural Network

The percepton or the neural network approach is really an interesting method. Based on some method that use learning the time to obtain a good model is more long than other linear or mathematical study.

For verify the model evolution we use a validation period.

This is the result obtained with the neural network solution.

RMSE=0.11787
The overlearning permit to detect som instability during the learning . The best result is obtained with 40 round.

Compare round and error in learning and validation. 

Compare three neurons size on learning errors.
