Training Objective of the Standard BERT Model

A deep sequence model is constructed by stacking multiple layers. Each layer consists of two sub-layers (e.g., a self-attention mechanism and a feed-forward network). A 'post-norm' architecture is used for each sub-layer, which involves applying the sub-layer's main function, adding a residual connection from the input, and then performing layer normalization. If x represents the input to a sub-layer and F(x) represents the output of that sub-layer's main function, which of the following expressions correctly computes the final output of that sub-layer?

A deep sequence model is built by stacking multiple layers. Each layer contains sub-layers (like self-attention or a feed-forward network) that use a 'post-norm' architecture. Arrange the following operations in the correct order as they would occur to transform an input vector within a single sub-layer.
