Activation function progress in deep learning, Relu, Elu, Selu, Geli , mish, etc - include table and graphs - day 24
Activation Function Formula Comparison Why (Problem and Solution) Mathematical Explanation and Proof Sigmoid \(\sigma(z) = \frac{1}{1 + e^{-z}}\) – Non-zero-centered output – Saturates for large values, leading to vanishing gradients Problem: Vanishing gradients for large positive or negative inputs, slowing down learning in deep networks. Solution: ReLU was introduced to avoid the saturation…
