Approximately Unimodal Likelihood Models for Ordinal Regressioncs.LG

Proposes models to better represent ordinal data with non-unimodal distributions.

problem Real-world ordinal data often have non-unimodal conditional probability distributions.

method Develops approximately unimodal likelihood models to better represent non-unimodal CPDs.

result Proposed models can effectively represent both unimodal and nearly unimodal CPDs.
