Data Science and Machine Learning (Theory and Projects) A to Z - Deep Neural Networks and Deep Learning Basics: Batch No

The video tutorial discusses the concept of mini batches in gradient descent, highlighting the assumption that all mini batches have the same distribution. It introduces the issue of covariate shift, where this assumption is violated, and presents batch normalization as a solution. Batch normalization standardizes features to have a mean of zero and a standard deviation of one, and it is applied layer-wise in neural networks. This process not only addresses covariate shift but also aids in regularization and accelerates convergence. The video concludes by emphasizing the importance of batch normalization in mini batch gradient descent and hints at discussing learning rates in the next video.
