Why does my manual derivative of Layer Normalization imply no gradient flow?
I recently tried computing the derivative of the layer norm function (https://arxiv.org/abs/1607.06450), an essential component of transformers, but the result suggests that no gradient flows through the … \\
\quad=\frac{-y_i}{\sigma}\mu_y\\
\textrm{BUT by properties of data following a standard normal distribution $\mu_y=0$, so}\\
\frac{dy_i}{dX}=\frac{-y_i}{\sigma}0\\
\quad=0\\
\textrm{Which means no gradient …
