why is tanh performing better than relu in simple neural

WebFeb 18, 2024 · In general, no. RELU will perform better on many problems but not all problems. Furthermore, if you use an architecture and set of parameters that is optimized to perform well with one activation function, you may get worse results after swapping in a different activation function. Often you will need to adjust the architecture and parameters …

WebSo, the way I understand it so far, Tanh is better than sigmoid because, Tanh distributes the gradients well compared to Sigmoid which handles the problem of vanishing or exploding gradient better, but Relu activation doesn't seem to distribute the gradients well because it's 0 for all negative values and increases linearly along the x-axis, the mean of the … WebAug 28, 2024 · The rules of ReLU are straighforward. If z is smaller than zero, a is zero. If z is larger than zero, the output stays z. In other words, ReLU replaces negative values with zero and leaves positive values unchanged. The gradient of this activation function is as easy as it can get. It is zero for values smaller than zero, otherwise one.

Here is a great answer by @NeilSlater on the same. It is basically trying to tell us that if we use ReLu's we will end up with a lot of redundant or dead nodes in a Neural Net (those which have a negative output) which do not contribute to the result, and thus do not have a derivative.
