A logistic function or logistic curve is a common S-shaped curve (sigmoid curve) with the equation f ( x ) = L 1 + e − k ( x − x 0 ) {\displaystyle f(x)={\frac...

The generalized logistic function or curve is an extension of the logistic or sigmoid functions. Originally developed for growth modelling, it allows...

A sigmoid function refers specifically to a function whose graph follows the logistic function. It is defined by the formula: σ ( x ) = 1 1 + e − x = e...

the value "1"), hence the labeling; the function that converts log-odds to probability is the logistic function, hence the name. The unit of measurement...

generalization of the logistic function to multiple dimensions, and is used in multinomial logistic regression. The softmax function is often used as the...

statistics, the logit (/ˈloʊdʒɪt/ LOH-jit) function is the quantile function associated with the standard logistic distribution. It has many uses in data...

statistics, the logistic distribution is a continuous probability distribution. Its cumulative distribution function is the logistic function, which appears...

function in which both asymptotes are approached by the curve symmetrically. It is a special case of the generalised logistic function. The function was...

The logistic map is a polynomial mapping (equivalently, recurrence relation) of degree 2, often referred to as an archetypal example of how complex, chaotic...

the ReLU, the GELU, which was used in the 2018 BERT model, the logistic (sigmoid) function used in the 2012 speech recognition model developed by Hinton...
