QuantileOutlierRejector

Reject values in the first and/or last quantiles defined by the number of buckets in the numBuckets parameter.

The bin ranges are chosen using the Algebird's QTree approximate data structure. The precision of the approximation can be controlled with the k parameter.

All values are transformed to zeros.

Values in the first and/or last quantiles are rejected as FeatureRejection.Outlier.

When using aggregated feature summary from a previous session, values outside of previously seen [min, max] will also report FeatureRejection.Outlier as rejection.
