What is ReLU Activation Function?
ReLU (Rectified Linear Unit) Activation Function is a mathematical function commonly used in artificial neural networks. It is applied to the output of a neuron to introduce non-linearity and enable the network to learn complex patterns and relationships in the data. ReLU function outputs the input value if it is positive, and if the input value is negative, it outputs zero.
How ReLU Activation Function Works?
The ReLU activation function works by applying a simple mathematical operation to the input value. If the input value is greater than or equal to zero, the output is equal to the input value. If the input value is negative, the output is zero. Mathematically, the ReLU function can be represented as:
f(x) = max(0, x)
Why ReLU Activation Function is Important?
The ReLU activation function is important in deep learning and machine learning because:
- It introduces non-linearity, allowing the network to learn complex patterns and relationships in the data.
- It helps in overcoming the vanishing gradient problem, which can hinder the learning process in deep neural networks.
- It is computationally efficient compared to other activation functions, such as sigmoid and tanh.
- It provides a sparse activation when compared to other activation functions, which can improve the efficiency of the network.
