Hi, when trying my neural network (input data to evaluate) I recieve an array answer instead of the desired one, which would be either one or zero. How can I solve this? Mi target array IS only ones and zeros.
With or without examples, inadequate problem explanations tend to result in inadequate problem solutions.
