mlx.nn.step

class step(x: array, threshold: float = 0.0)

Applies the Step Activation Function.

This function implements a binary step activation, where the output is set to 1 if the input is greater than a specified threshold, and 0 otherwise.

\[\begin{split}\text{step}(x) = \begin{cases} 0 & \text{if } x < \text{threshold} \\ 1 & \text{if } x \geq \text{threshold} \end{cases}\end{split}\]

Parameters:

threshold – The value to threshold at.
