SAS Help Center: Greedy Nearest Neighbor Matching
Web14. There are several good choices of fast nearest neighbor search libraries. ANN, which is based on the work of Mount and Arya. This work is documented in a paper by S. Arya and D. M. Mount. "Approximate nearest neighbor queries in fixed dimensions". In Proc. 4th ACM-SIAM Sympos. Discrete Algorithms, pages 271–280, 1993. Various solutions to the NNS problem have been proposed. The quality and usefulness of the algorithms are determined by the time complexity of queries as well as the space complexity of any search data structures that must be maintained. The informal observation usually referred to as the curse of dimensionality states that there is no general-purpose exact solution for NNS in high-dimensional Euclidean space using polynomial preprocessing and polylogarithmic search ti… WebThe default nearest neighbor matching method in M ATCH I T is ``greedy'' matching, where the closest control match for each treated unit is chosen one at a time, without trying to minimize a global distance measure. In contrast, ``optimal'' matching finds the matched samples with the smallest average absolute distance across all the matched pairs. sticky toffee pudding images
