Detailed Description

template<class Trie>
class shogun::CTrie< Trie >

Template class Trie implements a suffix trie, i.e. a tree in which all suffixes up to a certain length are stored.

It is excessively used in the CWeightedDegreeStringKernel and CWeightedDegreePositionStringKernel to construct the whole features space \(\Phi(x)\) and enormously helps here to speed up SVM training and evaluation.

Note that depending on the underlying structure used, a single symbol in the tree requires 20 bytes (DNATrie). It is also used to do the efficient recursion in computing positional oligomer importance matrices (POIMs) where the structure requires * 20+3*8 (POIMTrie) bytes.

Finally note that this tree may use compact internal nodes (for strings that appear without modifications, thus not requiring further branches), which may save a lot of memory on higher degree tries.
