We outline an implementation of Viterbi beam search that incorporates layered bigrams. Layered bigrams are class bigrams in which some nodes are themselves bigrams, resulting in a recursive structure. The implementation is in C++ and involves a hierarchy of classes. The paper outlines the main concepts and the corresponding C++ classes.
