WebFeb 11, 2024 · A sigmoid function is any function which has certain properties which give it the characteristic s-shape. Your question has many answers. For example, any function whose definition looks like. const k = 2; function sigmoid(z) { return 1 / (1 + Math.exp(-z/k)); } will fit the bill. The larger the k, the larger the useful domain. the helmsman group llc
