R Documentation

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.

Details

The typical procedure implemented in rsnns subclasses is the following:

generate the rsnns object with this object factory
generate the network according to the architecture needed
train the network (with train)

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.
