To prevent this problem, a small linear value is added to the weights by the ReLU to ensure the gradient of the ReLU graph never becomes zero in the ReLU vs sigmoid comparison.

These results are in contrast to known efficient algorithms for reliably learning linear threshold functions, where … WebOct 26, 2024 · Because it outputs 0 for every negative value, a ReLU neuron might get stuck in the negative side and always output 0, and it is unlikely for it to recover. This is called as the dying ReLU problem. This is a serious problem because if a neuron is dead, then it basically learns nothing. Because of this problem, there might be the case of a ...
