Batch Normalization: A Simple Explanation

Batch Normalization is a technique used in Neural Networks to normalize the inputs of each layer. It helps to improve the training process and makes the model more accurate and efficient.

In Neural Networks, each layer's inputs can have large variations depending on the data distribution. This can make the training process slower and more challenging because the network has to constantly adapt to different input ranges.

Batch Normalization addresses this issue by normalizing the inputs. It calculates the mean and standard deviation of each input batch and then applies a normalization operation using these statistics. This process scales and shifts the inputs to have a mean of zero and a standard deviation of one.

By normalizing the inputs, Batch Normalization helps the neural network to better learn the underlying patterns in the data. It reduces the effect of small changes in input values, making the training process more stable. This enables the model to converge faster and reach higher accuracy.

Furthermore, Batch Normalization acts as a form of regularization, reducing the reliance on dropout and other regularization techniques. It helps to prevent overfitting by reducing the impact of outliers and noise in the training data.

Overall, Batch Normalization is a powerful technique in Neural Networks that normalizes the inputs of each layer, making the training process faster, more stable, and ultimately improving the accuracy of the model.
