machine learning - Use neural network to learn a square wave function -

out of curiosity, trying build simple connected nn using tensorflow learn square wave function such following one: therefore input 1d array of x value (as horizontal axis), , output binary scalar value. used tf.nn.sparse_softmax_cross_entropy_with_logits loss function, , tf.nn.relu activation. there 3 hidden layers (100*100*100) , single input node , output node. input data generated match above wave shape , therefore data size not problem. however, trained model seems fail completed, predicting negative class always. so trying figure out why happened. whether nn configuration suboptimal, or due mathematical flaw in nn beneath surface (though think nn should able imitate function). thanks. as per suggestions in comment section, here full code. 1 thing noticed saying wrong earlier is, there 2 output nodes (due 2 output classes): """ see if neural net can find piecewise linear correlation in data """ import time import os import tens...
