Output Layer

Specialization of the Layer for Output.

Usage

eLayer/Output"

Configuration

These are settings required by this module.

Transformation Mask

  • Usage: e[“Transformation Mask”] = List of string

  • Description: Indicates a transformation to be performed to the output at the last layer of the neural network. [Order of application on forward propagation: 1/3]

Scale

  • Usage: e[“Scale”] = List of float

  • Description: Gives a scaling factor for each of the output values of the NN. [Order of application on forward propagation 2/3]

Shift

  • Usage: e[“Shift”] = List of float

  • Description: Shifts the output of the NN by the values given. [Order of application on forward propagation 3/3]

Output Channels

  • Usage: e[“Output Channels”] = unsigned integer

  • Description: Indicates the size of the output vector produced by the layer.

Weight Scaling

  • Usage: e[“Weight Scaling”] = float

  • Description: Factor that is mutliplied by the layers’ weights.

Engine

  • Usage: e[“Engine”] = string

  • Description: Specifies which Neural Network backend engine to use.

  • Options:

    • “Korali”: Uses Korali’s lightweight NN support. (CPU Sequential - Does not require installing third party software other than Eigen)

    • “OneDNN”: Uses oneDNN as NN support. (CPU Sequential/Parallel - Requires installing oneDNN)

    • “CuDNN”: Uses cuDNN as NN support. (GPU - Requires installing cuDNN)

Mode

  • Usage: e[“Mode”] = string

  • Description: Specifies the execution mode of the Neural Network.

  • Options:

    • “Training”: Use for training. Stores data during forward propagation and allows backward propagation.

    • “Inference”: Use for inference only. Only runs forward propagation. Faster for inference.

Layers

  • Usage: e[“Layers”] = knlohmann::json

  • Description: Complete description of the NN’s layers.

Timestep Count

  • Usage: e[“Timestep Count”] = unsigned integer

  • Description: Provides the sequence length for the input/output data.

Batch Sizes

  • Usage: e[“Batch Sizes”] = List of unsigned integer

  • Description: Specifies the batch sizes.
