Python Matrix Multiplication using a Dedicated Infix Operator

WebTo ensure that the variance of the dot product still remains one regardless of vector length, we use the scaled dot-product attention scoring function. That is, we rescale the dot-product by $1/\sqrt {d}$. We thus arrive at the first commonly used attention function that is used, e.g., in Transformers :cite: Vaswani.Shazeer.Parmar.ea.2024: WebIf the function to the left of the dot is "∘" (signifying null) then the composite function is an outer product, otherwise it is an inner product. An inner product intended for conventional matrix multiplication uses the + and × functions, replacing these with other dyadic functions can result in useful alternative operations.
