RMOA package for running streaming classifcation & regression models now at CRAN

Last week, we released the RMOA package at CRAN (http://cran.r-project.org/web/packages/RMOA). It is an R package to allow building streaming classification and regression models on top of MOA.
MOA is the acronym of 'Massive Online Analysis' and it is the most popular open source framework for data stream mining which is being developed at the University of Waikato: http://moa.cms.waikato.ac.nz. Our RMOA package interfaces with MOA version 2014.04 and focusses on building, evaluating and scoring streaming classification & regression models on data streams.

Classification & regression models which are possible through RMOA are:

– Classification trees:
  * AdaHoeffdingOptionTree
  * ASHoeffdingTree
  * DecisionStump
  * HoeffdingAdaptiveTree
  * HoeffdingOptionTree
  * HoeffdingTree
  * LimAttHoeffdingTree
  * RandomHoeffdingTree
– Bayesian classification:
  * NaiveBayes
  * NaiveBayesMultinomial
– Active learning classification:
  * ActiveClassifier
– Ensemble (meta) classifiers:
  * Bagging
      + LeveragingBag
      + OzaBag
      + OzaBagAdwin
      + OzaBagASHT
  * Boosting
      + OCBoost
      + OzaBoost
      + OzaBoostAdwin
  * Stacking
      + LimAttClassifier
  * Other
      + AccuracyUpdatedEnsemble
      + AccuracyWeightedEnsemble
      + ADACC
      + DACC
      + OnlineAccuracyUpdatedEnsemble
      + TemporallyAugmentedClassifier
      + WeightedMajorityAlgorithm

– Regression modelling:
  * AMRulesRegressor
  * FadingTargetMean
  * FIMTDD
  * ORTO
  * Perceptron
  * RandomRules
  * SGD (Stochastic Gradient Descent)
  * TargetMean

Interfaces are implemented to model data in standard files (csv, txt, delimited), ffdf data (from the ff package), data.frames and matrices.
