WebMay 7, 2024 · View source: R/farthest_point_sampling.R. Description. Farthest point sampling returns a reordering of the metric space P = p_1, ..., p_k, such that each p_i is the farthest point from the first i-1 points. Usage Web2.2 Farthest point sampling Farthest point sampling is based on the idea of repeatedly placing the next sample point in the middle of the least-known area of the sampling domain. In the following, we summarise the reasoning underlying this approach for both the uniform and non-uniform case presented in Eldar et al. [5, 6].
