ReLu

The Rectified Linear Unit (ReLU) is a widely used activation function in neural networks, particularly in deep learning models. It transforms the input by outputting the input directly if it is positive, and zero otherwise, mathematically expressed as ReLU(x) = max(0, x). This simple yet effective function helps introduce non-linearity into the model, allowing it to learn complex patterns in data. ReLU is favored for its computational efficiency and ability to mitigate the vanishing gradient problem, making it a popular choice for various applications in computer vision, natural language processing, and more.

ReLU

PyTorch documentation

Applies the rectified linear unit function element-wise: ReLU ( x ) = ( x ) + = max ⁡ ( 0 , x ) \text{ReLU}(x) = (x)^+ = \max(0, x) ReLU ( x ) = ( x ) + = max ( 0 , x ) inplace ( bool ) – can optional...
