Neural Network Always Produces Same/Similar Outputs for Any Input

Question

I have a problem where I am trying to create a neural network for Tic-Tac-Toe. However, for some reason, training the neural network causes it to produce nearly the same out

Answer 1

It's hard to tell without seeing a code sample, but a bias bug can have that effect (e.g. forgetting to add the bias to the input), so I would take a closer look at that part of the code.
