Permute3D

Description

Define the permute 3D layer according to its parameters. To be used for the TimeDistributed layer. Type : polymorphic.

 

Input parameters

 

Β parameters : layer parameters.

Β training?Β :Β boolean, whether the layer is in training mode (can store data for backward).
Default value β€œTrue”.
Β lda_coeff :Β float, defines the coefficient by which the loss derivative will be multiplied before being sent to the previous layer (since during the backward run we go backwards).
Default value β€œ1”.

 

Output parameters

 

Permute3D out : layer permute 3D architecture.

Example

All these exemples are snippets PNG, you can drop these Snippet onto the block diagram and get the depicted code added to your VI (Do not forget to install HAIBAL library to run it).

Permute3D layer inside TimeDistributed layer

1 – Generate a set of data

We generate an array of data of type single and shape [batch size = 10, time = 6, channels = 7, width = 5].

2 – Define graph

First, we define the first layer of the graph which is an Input layer (explicit input layer method). This layer is setup as an input array shaped [time = 6, channels = 7, width = 5].
Then, we add to the graph the TimeDistributed layer which we setup with a Permute3D layer using the define method.

3 – Run graph

We call the forward method and retrieve the result with the β€œPrediction 4D” method.
This method returns two variables, the first one is the layer information (cluster composed of the layer name, the graph index and the shape of the output layer) and the second one is the prediction with a shape of [batch_size, time, width, channels].
