By normalizing the mean and standard deviation of each sample independently, IN achieves better stability and prevents the overfitting that can occur with BN. IN has been shown to effectively improve the generalization ability of deep neural networks, especially in tasks such as image colorization, image synthesis, and texture transfer. Overall, IN is a valuable normalization technique for enhancing the performance and stability of deep learning models in various image-related tasks.

Contextual Normalization (CN)

Furthermore, another effective normalization technique employed in deep learning training is Contextual Normalization (CN). CN approaches the normalization process by subtracting the mean of the weights from each weight and then dividing by the standard deviation. This method aims to ensure that the range of values in the weight tensor remains balanced, thereby enhancing the training process and overall performance. By utilizing CN, the weights are transformed in a way that allows the model to learn more efficiently and effectively. This technique has proven to be particularly useful in domains where weight distribution plays a critical role, such as computer vision tasks and image recognition.
