View source on GitHub

Rectified linear unit.

With default values, it returns element-wise max(x, 0).

Otherwise, it follows: f(x) = max_value for x >= max_value, f(x) = x for threshold <= x < max_value, f(x) = alpha * (x - threshold) otherwise.

Arguments
x A tensor or variable.
alpha A scalar, slope of negative section (default=0.).
max_value float. Saturation threshold.
threshold float. Threshold value for thresholded activation.
Returns
A tensor.
