WebApr 8, 2024 · The sigmoid function has been repeatedly studied by many researchers because it has the following properties: it outputs real numbers between 0 and 1, maps a very large input domain to a small range of outputs, never loses information because it is a one-to-one function, increases monotonically and is also differentiable.
WebMar 7, 2024 · The building block of the deep neural networks is called the sigmoid neuron. Sigmoid neurons are similar to perceptrons, but they are slightly modified such that the output from the sigmoid neuron is much smoother than the step functional output from perceptron.In this post, we will talk about the motivation behind the creation of sigmoid …
WebNov 25, 2024 · ReLU is sometimes used as an activation function to address the vanishing gradient problems. But in some cases, on one hand it solves the vanishing gradient problem, on the other hand, it causes the exploding gradients problem. In this article, we will try to understand this tradeoff in detail that is caused by the ReLU function. WebThe two examples I gave were actually of positive cooperative phenomena, that is, the occurence of a first event favours the next events. There is also the titration curve, which is a sigmoid, but I don't think it's correlated. I'm asking that because I found it amazing that the same sort of curve appeared in the study of such different subjects.
