LTK.Learn.TSL.AugmentedSubsequences

This module implements a string extension learner for the TSL class. A variant of the tier-finding algorithm of Jardine and McMullin (2017) is used along with a notion of a potential valid tier-factor. This is an efficient online conversion of their algorithm.

Return the set of subsequence-interveners pairs of length \(k\) in a given word, as well as the adjacency factors of length \(k\) and \(k+1\). If a word is short enough to not contain any \(k\)-factors, the entire word, appropriately anchored, is included in the set.
