Analyzing the Impact of FFN Width on Activation Function Choice
In the context of a two-layer Feed-Forward Network (FFN) within a large language model, analyze the relationship between significantly increasing the hidden layer dimension and the choice of the non-linear activation function. Your analysis should address the distinct implications for both the model's computational efficiency and its overall performance.

An engineer is designing a neural network for a large language model and observes that the two-layer Feed-Forward Network (FFN) component is the primary computational bottleneck during training. The design specifies that the FFN's internal hidden layer dimension must be significantly larger than its input and output dimensions to ensure high model capacity. Given the goal of reducing the computational cost of the FFN while preserving its expressive power, which of the following design choices for the non-linear activation function (applied after the first linear layer) would be most effective?
