Function Documentation

template<typename T>
std::vector<size_t> bats::get_dM_ZZ_inds(const std::vector<T> &hds, const T rho, const T theta)

determine set of indices to use for dM-ZZ construction

Parameters

• hds – hausdorff distance of each point to point set. assume in decreasing order.

• rho – rips multiplier - should be >10 [OS15 thm 4.6]

• theta – depends on dimension of data. In [0.5, 1/sqrt(2))[OS15 eq. 1]

  • if unsure, set to 0.5 for finer discretization
