Method Detail

forgetGateBiasInit

public T forgetGateBiasInit(double biasInit)

Set forget gate bias initalizations. Values in range 1-5 can potentially help with learning or longer-term dependencies.

gateActivationFunction

public T gateActivationFunction(String gateActivationFn)

Activation function for the LSTM gates. Note: This should be bounded to range 0-1: sigmoid or hard sigmoid, for example

Parameters:

gateActivationFn - Activation function for the LSTM gates

gateActivationFunction

public T gateActivationFunction(org.nd4j.linalg.activations.Activation gateActivationFn)

Activation function for the LSTM gates. Note: This should be bounded to range 0-1: sigmoid or hard sigmoid, for example

Parameters:

gateActivationFn - Activation function for the LSTM gates

gateActivationFunction

public T gateActivationFunction(org.nd4j.linalg.activations.IActivation gateActivationFn)

Activation function for the LSTM gates. Note: This should be bounded to range 0-1: sigmoid or hard sigmoid, for example

Parameters:

gateActivationFn - Activation function for the LSTM gates
