dragon.nn.
prelu
(
inputs,
data_format='NCHW',
**kwargs
)[source]¶Apply the parametric rectified linear unit. [He et.al, 2015].
The PReLU function is defined as:
\[\text{PReLU}(x) = \begin{cases} x, & \text{ if } x \geq 0 \\ weight * x, & \text{ otherwise } \end{cases} \]Examples:
x = dragon.constant([[-1., 0., 1.]]) w = dragon.fill((3,), value=0.25, dtype=x.dtype) print(dragon.nn.prelu([x, w]))
- Parameters:
- inputs (Sequence[dragon.Tensor]) – The input and weight.
- data_format (str, optional, default='NCHW') –
'NCHW'
or'NHWC'
.
- Returns:
dragon.Tensor – The output tensor.
