A Gentle Introduction To Sigmoid Function

WebI understand we need to find the derivative of the activation function used. I'm using the standard sigmoid function. f (x) = 1 / (1 + e^ (-x)) and I've seen that its derivative is. dy/dx = f (x)' = f (x) * (1 - f (x)) This may be a daft question, but does this mean that we have to pass x through the sigmoid function twice during the equation ... WebSince a Boltzmann Machine is symmetric, we should have : For simplicity reasons we will ignore the biases in the equations that follow. The equation of the energy function E will become: In Gibbs sampling, the conditional probability will be computed just like in standard BM, by applying the sigmoid function on the energy gap for node i ...
