| Research Abstract |
As a data-dependent complexity measure, we proposed data-dependent VC dimension of Sperner family, and in hyper-rectangle subclass problem, we developed a fast algorithm for datasets with small such VC dimension. We also empirically showed efficiency of the algorithm using real data. Furthermore, as a complexity measure of contiguous repetition structure of a string, we proposed the size of a minimum repetition representation string (MRRS) for a given string. We developed a fast algorithm for constructing an MRRS and analyzed the repetition structure of DNA sequences using the algorithm.
