For small values (<-5), sigmoid returns a value close to zero, and for large values (>5) the result of the function gets close to 1.
![]() It can be shown that Swish and GELU both are a smooth approximation of ReLU. tf.(x) Sigmoid activation function, sigmoid (x) 1 / (1 + exp (-x)). GELU 8 is an another popular smooth activation function. Swish 7 is a non-linear activation function proposed by the Google brain team, and it shows some good improvement of ReLU. Tensor with the same shape and dtype as x. ReLU 6 are a few of them though they marginally improve performance of ReLU. This function will iteratively improve parameters (filters kernel values, weights and bias of neurons.
