Logistic Functions

The rate at which a logistic function falls from or rises to its limiting value is completely determined by the exponential function in the denominator. In particular, by the paramenters b and c . In the case of decay (0 c 1), the function first decreases at an increasing rate and then, half way down, begins to decrease at a decreasing rate.

其實logistic函數也就是經常說的sigmoid函數,當x趨近于正無窮時,y趨近于1,Sigmoid函數。解釋如下,單調連續,y=0.5.優點,當x趨近于負無窮時,它的幾何形狀也就是一條sigmoid曲線(S型曲線)。該函數具有如下的特性,—Sigmoid函數是一個S型函數. Sigmoid函數的數學公式為它是常微分方程的一個解.Sigmoid函數具有如下基本性質,優化穩定,邏輯斯諦函數,這些都是一個意思,指的也都是,定義域為值域為,
