For example, ... Web31 de jan. de 2024 · 1. We know that a feed forward neural network with 0 hidden layers (i.e. just an input layer and an output layer) with a sigmoid activation function at the end should be equivalent to logistic regression. I wish to prove this to be true, but I need to fit 0 hidden layers using the sklearn MLPClassifier module specifically.
