Leaky ReLU Activation Function: Implementation in Python
💥💥 GET FULL SOURCE CODE AT THIS LINK 👇👇
Leaky ReLU (Rectified Linear Unit) is a widely used activation function in machine learning and deep learning models due to its ability to mitigate the vanishing gradient problem. In contrast to the traditional ReLU activation function, Leaky ReLU allows a small positive gradient for negative input values, avoiding the problem of dying neurons. In this description, we will discuss the formulation, implementation, and benefits of the Leaky ReLU activation function using Python.
Formulation:
The Leaky ReLU function is defined as:
f(x) = max(0, ax) for x = 0
f(x) = x for x 0
Where 'a' is a constant, usually set to 0.01, to allow a small leak for negative inputs.
Implementation:
To implement Leaky ReLU activation in Python, use NumPy and create a custom activation function:
```python
import numpy as np
def leaky_relu(x, a=0.01):
```
Benefits:
compensate_for_dying_neurons The Leaky ReLU function outperforms traditional ReLU in handling the vanishing gradient problem by allowing some gradients to remain significant when backpropagating. This property directly contributes to more successful training of deeper neural networks, which increases the overall performance and efficiency.
