WebNearestNeighbors implements unsupervised nearest neighbors learning. It acts as a uniform interface to three different nearest neighbors algorithms: BallTree, KDTree, and a brute-force algorithm based on routines in sklearn.metrics.pairwise . The choice of neighbors search algorithm is controlled through the keyword 'algorithm', which must … Last week, we started to see how evolutionary trees can be constructed from distance matrices. This week, we will encounter additional algorithms for this purpose, including the neighbor-joining algorithm, which has become one of the top-ten most cited papers in all of science since its introduction ...
