An engineer is building a deep neural network for sequence processing. Each layer of the network consists of a self-attention mechanism followed by a position-wise sub-layer. The engineer designs this position-wise sub-layer to be composed of two consecutive linear transformations. What is the most significant negative consequence of omitting a non-linear activation function between these two linear transformations?

An engineer is building a deep neural network for sequence processing. Each layer of the network consists of a self-attention mechanism followed by a position-wise sub-layer. The engineer designs this position-wise sub-layer to be composed of two consecutive linear transformations. What is the most significant negative consequence of omitting a non-linear activation function between these two linear transformations?
A researcher modifies the position-wise sub-layer within a sequence processing model. The standard design for this sub-layer is a sequence of: a linear transformation, a non-linear activation, and a second linear transformation. The researcher's modification adds a second non-linear activation function immediately after the final linear transformation. Which of the following best evaluates the impact of this architectural change?
