Der3ActFunc function

Third derivative of activation function of neuron

Evaluate third derivative of activation function of a neuron

Der3ActFunc(type = "sigmoid", ...)

Arguments

• type: character name of the activation function
• ...: extra arguments needed to calculate the functions

Returns

numeric output of the neuron

Examples

# Return derivative of the sigmoid activation function of a neuron
ActivationFunction <- Der3ActFunc("sigmoid")
# Return derivative of the tanh activation function of a neuron
ActivationFunction <- Der3ActFunc("tanh")
# Return derivative of the activation function of several layers of neurons
actfuncs <- c("linear","sigmoid","linear")
ActivationFunctions <- sapply(actfuncs, Der3ActFunc)
