Branch	Build Status
master

• AMRulesRegressor (Stream Processor)
  

  This extension performs regression tasks using the AMRulesRegressor algorithm.

• clusTree (Stream Processor)
  

  This extension performs clustering on a streaming data set. Initially a micro cluster model is generated using the ClusTree algorithm, and weighted k-means is periodically applied to micro clusters to generate a macro cluster model with the required number of clusters. Data points can be of any dimensionality, but the dimensionality should be constant throughout the stream. Euclidean distance is taken as the distance metric.

• hoeffdingTreeClassifier (Stream Processor)
  

  This extension performs classification using the Hoeffding Adaptive Tree algorithm for evolving data streams that use ADWIN to replace branches with new ones.

• updateAMRulesRegressor (Stream Processor)
  

  This extension performs the build/update of the AMRules Regressor model for evolving data streams.

• updateHoeffdingTree (Stream Processor)
  

  This extension performs the build/update of Hoeffding Adaptive Tree for evolving data streams that use ADWIN to replace branches for new ones.
