WebOct 18, 2024 · So how does the Swish activation function work? The function itself is very simple: f ( x) = x σ ( x) Where σ ( x) is the usual sigmoid activation function. σ ( x) = ( 1 + e − x) − 1. It looks like this: What’s interesting about this is that unlike every other activation function, it is not monotonically increasing.
