PReLU 4D

Description

Defines the weight of the PReLU4D layer selected by the index. Type : polymorphic.

Input parameters

 Model in : model architecture.
index : integer, index of layer.
alpha : array, 3D alpha values.  alpha = [input_dim1, input_dim2, input_dim3].

Output parameters

 Model out : model architecture.

Dimension

• alpha = [input_dim1, input_dim2, input_dim3]

Its size depends on the input of the PReLU layer.
For example, if the layer has an entry [batch_size = 10, input_dim1 = 7, input_dim2 = 5, input_dim3 = 3] then alpha will have a size [input_dim1 = 7, input_dim2 = 5, input_dim3 = 3].
The size can also depend on the “shared_axis” parameter that you set to the PReLU layer. Each axis specified in this param is represented by a 1 in the weights.
For example, if you set the parameter with the values [2], alpha will have a size [input_dim1 = 7, 1, input_dim3 = 3].
Another example, if you define the parameter with the values [2, 3], alpha will have a size [input_dim1 = 7, 1, 1].
