RSNNS (version 0.4-5)

rsnnsObjectFactory: Object factory for generating rsnns objects

Description

The object factory generates an rsnns object and initializes its member variables with the values given as parameters. Furthermore, it generates an object of SnnsR-class. Later, this information is to be used to train the network.

Usage

rsnnsObjectFactory(subclass, nInputs, maxit, initFunc,
    initFuncParams, learnFunc, learnFuncParams, updateFunc,
    updateFuncParams, shufflePatterns = TRUE,
    computeIterativeError = TRUE, pruneFunc = NULL,
    pruneFuncParams = NULL)

Arguments

subclass

the subclass of rsnns to generate (vector of strings)

nInputs

the number of inputs the network will have

maxit

maximum of iterations to learn

initFunc

the initialization function to use

initFuncParams

the parameters for the initialization function

learnFunc

the learning function to use

learnFuncParams

the parameters for the learning function

updateFunc

the update function to use

updateFuncParams

the parameters for the update function

shufflePatterns

should the patterns be shuffled?

computeIterativeError

should the error be computed in every iteration?

pruneFunc

the pruning function to use

pruneFuncParams

the parameters for the pruning function. Unlike the other functions, these have to be given in a named list. See the pruning demos for further explanation.

Value

• a partly initialized rsnns object

Details

The typical procedure implemented in rsnns subclasses is the following:

• generate thersnnsobject with this object factory
• generate the network according to the architecture needed
• train the network (withtrain)

In every rsnns object, the iterative error is the summed squared error (SSE) of all patterns. If the SSE is computed on the test set, then it is weighted to take care of the different amount of patterns in the sets.
