Sigmoid function detail added

davharris commented 6 years ago

I don't think the use of lowercase sigma to represent the sigmoid function is common outside of the literature on neural networks.

If a typical reader sees a lowercase sigma, I'd expect that it probably refers to a standard deviation instead.

The definition Sigmoid function is real-valued, monotonic, and differentiable having a non-negative first derivative which is bell shaped. should be able to be fully understood using only the previous words in this document, it shouldn't be added until this is possible.
