CS365: BACKPROPAGATION (CONTINUED)

Backpropagation is an example of supervised learning. ... The transfer function used by the hidden units in back-propagation is usually a sigmoid (or logistic) function, it is a smooth continuously differentiable curve, and limits the output (activation) of a unit between 0 and 1 (Fig. 1). ... Some neural network packages do this for you in a ... ................
