Answer (1 of 2): It doesn’t really matter as long as you’re not using sigmoid or tanh. There has been little proof that anything different from ReLU consistently brings significant improvement to your results.
“Soft sign: The soft sign function is another nonlinearity which can be considered an alternative to tanh since it too does not saturate as easily as hard clipped functions” I recommend reading the source as it talks about the different types of non-linearities.
“The softsign networks seem to be more robust to the initialization procedure than the tanh networks, presumably because of their gentler non-linearity.” In terms of biological analogy: ReLU > Sigmoid > Tanh In a later paper, Glorot, Bordes, & Bengio [2011] show that the Tanh and SoftSign functions do not have necessary and desirable
In terms of biological analogy: ReLU > Sigmoid > Tanh. In a later paper, Glorot, Bordes, & Bengio [2011] show that the Tanh and SoftSign functions do not have necessary and desirable properties. Tanh and SoftSign often do not deactivate, and it is shown both biologically and in deep nets that deactivation (or activation sparsity) is necessary.
May 01, 2018 · Fig. 4 Hyperbolic Tangent (TanH) activation SoftSign. Works as a continuous approximation of the sign function, and its graph looks very similar to TanH. However, TanH grows exponentially, whereas SoftSign — polynomially. The range of SoftSign is also (-1; +1).

functions include softplus, tanh, swish, linear, Maxout, sigmoid, Leaky ReLU, and ReLU. The ... Softsign Activation Function ... Softsign vs tanh function.
05.11.2019 · Even though tanh and softsign functions are closely related, the important difference is that tanh converges exponentially whereas softsign converges polynomially. Mathematical Equation : f...
Difference between Softsign Function and Hyperbolic tangent (tanh) – However, I have mentioned that Softsign function is similar to the tanh function. Still, there are differences between them. The basic difference is Hyperbolic tangent function converges exponentially. In the case of Softsign function it converges polynomially.

Nov 10, 2017 · As an alternative to hyperbolic tangent, softsign is an activation function for neural networks. Even though tanh and softsign functions are closely related, tanh converges exponentially whereas softsign converges polynomially. Even though softsign appears in literature, it would not be adopted in practice as much as tanh.
19.08.2020 · Sigmoid and tanh should be avoided due to vanishing gradient problem. Softplus and Softsign should also be avoided as Relu is a better choice. Relu should be preferred for hidden layers. If it is causing the dying relu problem then its modifications like leaky relu, ELU, SELU, etc should be used. For deep networks, swish performs better than relu.
ReLU is one of the cheapest activation functions out there, it induces sparsity and alleviates the vanishing gradient problem of tanh and the sigmoid to an ...
