tf.keras.backend.relu(
    x, alpha=0.0, max_value=None, threshold=0
)

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.
