Detailed Description¶
template<typename VecType = arma::vec, typename TMetricType = metric::LMetric<2, true>>class mlpack::bound::BallBound< VecType, TMetricType >¶
Ball bound encloses a set of points at a specific distance (radius) from a specific point (center). TMetricType is the custom metric type that defaults to the Euclidean (L2) distance. Template Parameters:VecType Type of vector (arma::vec or
arma::sp_vec).
TMetricType metric type used in the distance measure.
