In artificial neural networks, the sigmoid and complementary log log activation functions are similar in shape when plotted on a graph. I would like to know when to use the two functions and their pros and cons. Thanks in advance :)
This paper is behind a pay-wall but is one of the only references that I've found.

The types of activation functions most often used in artificial neural networks are logistic and hyperbolic tangent. Activation functions used in ANN have been said to play an important role in the convergence of the algorithms used. This paper uses sigmoid functions in the processing units of neural networks. Such functions are commonly applied in statistical regression models. The nonlinear functions implemented here are the inverse of complementary log-log and probit link functions. A Monte Carlo framework is presented to evaluate the results of prediction power with these nonlinear functions.
