Leaky relu

WebLeaky ReLU関数はLeaky Rectified Linear Unitの略称で、ReLUの拡張版です。 関数への入力値が0より下の場合には出力値が入力値をα倍した値(※αの値は基本的に0.01)、入力値が0以上の場合には出力値が入力値と同じ値となる関数です。 Leaky ReLUのメリット – Dying ReLUの問題が発生するのを防ぎます。 ReLUのバリエーションは、負の領域に小 … Web21 dec. 2024 · 4. Leaky ReLU Activation Function. Leaky ReLu is nothing more than an improved version of the ReLU activation function. As IU mentioned above, it’s common that, by using ReLU, we may kill some neurons in our neural network and these neurons will never activate on any data again. Leaky ReLU was defined to address this problem.
