SigmoidKind
ReferencesThe family of common sigmoid (S-shaped) curves. All variants share the same anchors — an inflection point and a tangent slope — and differ only in how quickly they saturate towards their asymptotes (their tail behaviour).
Enum values
| Name | Value | Description |
|---|---|---|
| Logistic | 0 | Logistic curve 1/(1+e⁻ˣ). Exponential tails. |
| Arctangent | 1 | Arctangent. Heavy, algebraic (~1/x) tails. |
| ErrorFunction | 2 | Error function (the Normal CDF). Gaussian tails — the fastest saturation. |
| Algebraic | 3 | Algebraic sigmoid x/(1+|x|). Cheap, algebraic tails. |
