Question

In regression,the value of the sigmoid function is bounded between

Answer 1

Answer:

Its outputs range from 0 to 1, and are often interpreted as probabilities (in, say, logistic regression). The tanh function, a.k.a. hyperbolic tangent function, is a rescaling of the logistic sigmoid, such that its outputs range from -1 to 1. (There's horizontal stretching as well.) tanh(x)=2g(2x)−1.
