Benefits of Batch Normalization

  • Faster Convergence: By stabilizing the gradients, BN allows you to use higher learning rates, which can significantly speed up training.
  • Reduced Internal Covariate Shift: As the network trains, the distribution of activations within a layer can change (internal covariate shift). BN helps mitigate this by normalizing activations before subsequent layers, making the training process less sensitive to these shifts.
  • Initialization Insensitivity: BN makes the network less reliant on the initial weight values, allowing for more robust training and potentially better performance.

Batch Normalization Implementation in PyTorch

Batch Normalization (BN) is a critical technique in the training of neural networks, designed to address issues like vanishing or exploding gradients during training. In this tutorial, we will implement batch normalization using PyTorch framework.

What is Batch Normalization?

Gradients are used to update weights during training, that can become unstable or vanish entirely, hindering the network’s ability to learn effectively. Batch Normalization (BN) is a powerful technique that addresses these issues by stabilizing the learning process and accelerating convergence. Batch Normalization(BN) is a popular technique used in deep learning to improve the training of neural networks by normalizing the inputs of each layer. Implementing batch normalization in PyTorch models requires understanding its concepts and best practices to achieve optimal performance....

How Batch Normalization works?

During each training iteration (epoch), BN takes a mini batch of data and normalizes the activations (outputs) of a hidden layer. This normalization transforms the activations to have a mean of 0 and a standard deviation of 1. While normalization helps with stability, it can also disrupt the network’s learned features. To compensate, BN introduces two learnable parameters: gamma and beta. Gamma rescales the normalized activations, and beta shifts them, allowing the network to recover the information present in the original activations....

Implementing Batch Normalization in PyTorch

PyTorch provides the nn.BatchNormXd module (where X is 1 for 1D data, 2 for 2D data like images, and 3 for 3D data) for convenient BN implementation. In this tutorial, we will see the implementation of batch normalizationa and it’s effect on model. We will train the model and highlight the loss before and after using batch normalization with MNIST dataset widely used dataset in the field of machine learing and computer vision. This dataset consists of a collection of 28X28 pixel grayscale images of handwritten digits ranges from (0 to 9) inclusive along with their corresponding labels....
