An Intuition for Attention | Jay Mody

Deriving the equation for scaled dot product attention.

An Intuition for Attention | Jay Mody An Intuition for Attention October 22, 2022 ChatGPT and other large language models use a special type of neural network called the transformer. The transformer defining feature is the attention mechanism. Attention is defined by the equation: \[\text{attention}(Q, K, V) = \text{softmax}(\frac{QK^T}{\sqrt{d_k}})V\] Attention can come in different forms, but this version of attention (known as scaled dot product attention) was first proposed in the original transformer paper . In this post, we'll build an intuition for the above equation by deriving it from
