It is defined as:
threshold(x) = x if x > threshold,
threshold(x) = default_value otherwise.
activation_threshold(x, threshold, default_value)A tensor, the result from applying the activation to the input tensor x.
Input tensor.
The value that decides when to retain or replace x.
Value to assign when x <= threshold.
