MOA (Massive Online Analysis)[1] is a free open-source software specific for Data stream mining with Concept drift. It is written in Java and developed at the University of Waikato, New Zealand.

Description

MOA is an open-source framework software that allows to build and run experiments of machine learning or data mining on evolving data streams. It includes a set of learners and stream generators that can be used from the Graphical User Interface (GUI), the command-line, and the Java API. MOA contains several collections of machine learning algorithms:

  • Classification
    • Bayesian classifiers
      • Naive Bayes
      • Naive Bayes Multinomial
    • Decision trees classifiers
      • Decision Stump
      • Hoeffding Tree
      • Hoeffding Option Tree
      • Hoeffding Adaptive Tree
    • Meta classifiers
      • Bagging
      • Boosting
      • Bagging using ADWIN
      • Bagging using Adaptive-Size Hoeffding Trees.
      • Perceptron Stacking of Restricted Hoeffding Trees
      • Leveraging Bagging
      • Online Accuracy Updated Ensemble
    • Function classifiers
    • Drift classifiers
    • Multi-label classifiers[2]
    • Active learning classifiers [3]
  • Regression
  • Clustering[6]
    • StreamKM++
    • CluStream
    • ClusTree
    • D-Stream
    • CobWeb.
  • Outlier detection[7]
    • STORM
    • Abstract-C
    • COD
    • MCOD
    • AnyOut[8]
  • Recommender systems
    • BRISMFPredictor
  • Frequent pattern mining
  • Change detection algorithms[11]

These algorithms are designed for large scale machine learning, dealing with concept drift, and big data streams in real time.

MOA supports bi-directional interaction with Weka (machine learning). MOA is free software released under the GNU GPL.
