The Essential k-NN Algorithm

Learn about the k-NN algorithm and its implementation using different modules.


We can summarize the kk-NN algorithm as having the following steps:

  1. Create a list of all (distance, training sample) pairs.
  2. Sort these in ascending order.
  3. Pick to the first kk, which will be the k nearest neighbors.
  4. Chose the mode (the highest frequency) label for the kk nearest neighbors.

The implementation would look like this:
