Pre-sizing is a technique for preparing images for training a neural network.

In standard image pipelines, images are resized to a size suitable for our …

Categorical Cross-Entropy Loss Function, also known as Softmax Loss, is a loss function used in multiclass classification model training. It applies the Softmax Activation Function …

Cross-entropy measures the average number of bits required to identify an event if you had a coding scheme optimised for one probability distribution $q …$

Entropy is a measure of uncertainty of a random variable's possible outcomes.

It's highest when there are many equally likely outcomes. As you introduce more …
