tf.compat.v1.keras.backend.relu
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. |
