This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
The library provides implementation of the second-order, linear conditional random fields (CRFs) with position-wise constraints imposed over label values. Each label consists of a vector of smaller, atomic labels, and over each tier (layer) a separate set of model features is defined.
