MLP_net: MLP_net function

Description

A function to define a multilayer perceptron and compute quantities for backpropagation, if needed.

Usage

MLP_net(input, weights, bias, dims, nlayers, activ, back = TRUE, regulariser)

Value

a list object containing the evaluated forward pass and also, if selected, quantities for backpropagation.

Arguments

input

input data, a list of vectors (i.e. ragged array)

weights

a list object containing weights for the forward pass, see ?weights2list

bias

a list object containing biases for the forward pass, see ?bias2list

dims

the dimensions of the network as stored from a call to the function network, see ?network

nlayers

number of layers as stored from a call to the function network, see ?network

activ

list of activation functions as stored from a call to the function network, see ?network

back

logical, whether to compute quantities for backpropagation (set to FALSE for feed-forward use only)

regulariser

type of regularisation strategy to, see ?train, ?no_regularisation ?L1_regularisation, ?L2_regularisation
