00:00:03,200 --> 00:00:06,162
A k-nearest neighbor model
is a modeling approach

2
00:00:06,162 --> 00:00:09,470
where we take an observation
and find closely related

3
00:00:09,470 --> 00:00:11,945
other observations
or neighbors,

4
00:00:12,295 --> 00:00:15,460
and use information about
those neighbors to make a prediction.

5
00:00:16,060 --> 00:00:16,866
For instance,

6
00:00:16,866 --> 00:00:20,342
if a given flower is very similar
to five other flowers,

7
00:00:20,342 --> 00:00:22,564
that are classified
as flower type A,

8
00:00:23,034 --> 00:00:26,308
it would stand to reason
we can predict our given flower

9
00:00:26,308 --> 00:00:28,274
is also flower type A.
