💡 What is Batch Size? Batch size refers to the number of samples used in one iteration to speed up the training process. We usually face these Trade-offs: 1. Smaller batch size: * Slower convergence. * More accurate gradient estimates. * Not Fully utilizes GPU 2. Larger batch size: * Faster convergence. * Less accurate gradient estimates. * Fully utilizes GPU So, its recommended to use **mini-batch gradient descent** to strike a balance between the computational efficiency of batch gradient descent and the online update of stochastic gradient descent.
