Chimerge sklearn

WebAbstract. We show that a commonly-used sampling theoretical attribute discretization algorithm ChiMerge can be implemented efficiently in the online setting. Its benefits include that it is efficient, statistically justified, robust to noise, can be made to produce low-arity partitions, and has empirically been observed to work well in practice.
