Parametric Rectified Linear Unit (PReLU) is an innovative adaptation of the traditional Rectified Linear Unit (ReLU) activation function, aimed at enhancing the adaptability and performance of neural networks. Introduced by He et al. in 2015, PReLU builds on the concept of Leaky ReLU by introducing a learnable parameter that adjusts the slope of the activation function for negative inputs during the training process. This modification allows neural networks to dynamically learn the most effective way to activate neurons across different layers and tasks.
