- Class Summary
  Class | Description
  --- | ---
  DatasetWrapper<C extends Serializable,D extends AutoCloseable> | A dataset wrapper that allows to introduce new functionality based on common `compute` methods.
  FeatureMatrixWithLabelsOnHeapData | A partition `data` of the containing matrix of features and vector of labels stored in heap.
  FeatureMatrixWithLabelsOnHeapDataBuilder<K,V,C extends Serializable,CO extends Serializable> | A partition `data` builder that makes `DecisionTreeData`.
  SimpleDataset<C extends Serializable> | A simple dataset introduces additional methods based on a matrix of features.
  SimpleLabeledDataset<C extends Serializable> | A simple labeled dataset introduces additional methods based on a matrix of features and labels vector.

## Package org.apache.ignite.ml.dataset.primitive Description

Package that contains basic primitives build on top of `Dataset`. Primitives are simple components that can be used in other algorithms based on the dataset infrastructure or for debugging. Primitives include partition `context` implementations, partition `data` implementations and extensions of dataset. Partition `context` and `data` implementations can be used in other algorithm in case these algorithm doesn't need to keep specific data and can work with standard primitive `data` or `context`. Extensions of dataset provides basic most often used functions that can be used for debugging or data analysis.
