Could you please elaborate on the concept of a "mask" in the context of neural networks? Specifically, how does it function and what role does it play in the network's overall operation? Are masks used primarily for regularization or are they employed for other purposes as well? Additionally, are there different types of masks and if so, how do they differ from each other? Lastly, could you provide an example or two to further illustrate the concept of a mask in a neural network? Thank you for your time and assistance in clarifying this aspect of neural network architectures.

TensorFlow/Keras provides a mechanism known as masking to handle specific parts of tensors during the forward pass of neural networks.

Masking allows users to disregard sections of tensors, often those that are set to zero, in the context of processing sequential data.

This feature is particularly useful when dealing with sequences of varying lengths, as padding is commonly employed to standardize the length of all sequences.

By masking out the padded portions, the model can focus on the actual data within the sequences, ignoring the irrelevant padded values.

In TensorFlow/Keras, masking is implemented as a layer that can be added to your model's architecture, allowing you to specify which parts of the input tensor should be disregarded.
