tf.keras.backend.relu(
x,
alpha=0.0,
max_value=None,
threshold=0
)
Defined in tensorflow/python/keras/backend.py.
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.
