The Concept of Multi-Head Attention Mechanism and Its Implementation In Pytorch

In this post, we will discuss building a multi-head attention layer in a Transorfmer, which is a more advanced variant of the attention layer that has proven to be very effective in practice. Moreover, we will show you how to implement such Layer using Pytorch.  Building a Multi-Head Attention Layer in a Transformer The Transformer is a powerful neural network architecture that has achieved state-of-the-art performance on a variety of natural language processing tasks. One key component of the Transformer is the attention layer, which allows the model to focus on specific parts of the input while processing it.  The Attention Mechanism At a high level, the attention mechanism works by allowing the model to "pay attention" to different parts of the input while processing it. This is done by first projecting the input and key-value pairs using linear transformations, and then computing the attention weights using a dot product between the projected input and the keys.
