WitrynaThe logistic regression function 𝑝 (𝐱) is the sigmoid function of 𝑓 (𝐱): 𝑝 (𝐱) = 1 / (1 + exp (−𝑓 (𝐱)). As such, it’s often close to either 0 or 1. The function 𝑝 (𝐱) is often interpreted as the predicted probability that the output for a given 𝐱 is equal to 1. Therefore, 1 − 𝑝 (𝑥) is the probability that the output is 0.
