activation function

activation function
функция активации
в ИНС - функция, ограничивающая (либо определяющая) амплитуду выходного сигнала нейрона в зависимости от так называемого потенциала активации (activation potential), равного взвешенной сумме сигналов всех входов нейрона. Бывает пороговой, линейной и нелинейной.
Syn:
squashing function (функция сжатия)
см. тж. bias, neural network
