0:00:03.200,0:00:06.162 A k-nearest neighbor model[br]is a modeling approach 0:00:06.162,0:00:09.470 where we take an observation[br]and find closely related 0:00:09.470,0:00:11.945 other observations[br]or neighbors, 0:00:12.295,0:00:15.460 and use information about[br]those neighbors to make a prediction. 0:00:16.060,0:00:16.866 For instance, 0:00:16.866,0:00:20.342 if a given flower is very similar[br]to five other flowers, 0:00:20.342,0:00:22.564 that are classified[br]as flower type A, 0:00:23.034,0:00:26.308 it would stand to reason[br]we can predict our given flower 0:00:26.308,0:00:28.274 is also flower type A.
