Neural network (perceptron) - visualizing decision boundary (as a hyperplane) when performing binary classification

Question

I would like to visualize the decision boundary for a simple neural network with only one neuron (3 inputs, binary output). I\'m extracting the weights from a Keras NN model

Answer 1

The decision boundary from your network is not ax + by + cz = d but ax + by + cz + d = 0.
