A sub-layer within a neural network block is designed to process an input tensor, X. The computational flow is as follows: first, a primary function F (such as a self-attention mechanism) is applied to X. Second, a normalization operation is applied to the result of the function F. Finally, the original input tensor X is added to the normalized result via a residual connection to produce the final output, Y. Which of the following expressions correctly models this specific sequence of operations?
