-------------------------------
Summary: Add feature transformer interface to improve the power
and flexibility of existing machine learning model
Key: HAMA-822
URL: https://issues.apache.org/jira/browse/HAMA-822
Project: Hama
Issue Type: New Feature
Components: machine learning
Affects Versions: 0.7.0
Reporter: Yexi Jiang
Assignee: Yexi Jiang
Add the feature transformer interface to improve the power of the existing
learning model.
If the user implicitly know how to transform and extract the features, the user
can implement the concrete feature transformer to extract the useful
information from the original features.
The implemented feature transformer can reduce the dimension of the original
features to improve the generalization of the model. Or it can transform the
original nonlinearly separable features by mapping them to a linear separable
space.
