class SReLU[T] extends bigdl.nn.keras.SReLU[T] with Net

S-shaped Rectified Linear Unit. It follows: f(x) = tr + ar(x - tr) for x >= tr, f(x) = x for tr > x > tl, f(x) = tl + al(x - tl) for x <= tl.

When you use this layer as the first layer of a model, you need to provide the argument inputShape (a Single Shape, does not include the batch dimension).

T

Numeric type of parameter(e.g. weight, bias). Only support float/double now.

    tLeftInit

    Initialization function for the left part intercept. Default is Zeros. You can also pass in corresponding string representations such as 'zero' or 'normal', etc. for simple init methods in the factory method.

    aLeftInit

    Initialization function for the left part slope. Default is Xavier. You can also pass in corresponding string representations such as 'glorot_uniform', etc. for simple init methods in the factory method.

    tRightInit

    Initialization function for the right part intercept. Default is Xavier. You can also pass in corresponding string representations such as 'glorot_uniform', etc. for simple init methods in the factory method.

    aRightInit

    Initialization function for the right part slope. Default is Ones. You can also pass in corresponding string representations such as 'one' or 'normal', etc. for simple init methods in the factory method.

    sharedAxes

    Array of Int. The axes along which to share learnable parameters for the activation function. Default is null. For example, if the incoming feature maps are from a 2D convolution with output shape (batch, height, width, channels), and you wish to share parameters across space so that each filter only has one set of parameters, set 'sharedAxes = Array(1,2)'.

    inputShape

    A Single Shape, does not include the batch dimension.
