Python k-nearest neighbors

Implementation of k-nearest neighbors algorithm in Python.

Number of neighbors is parametrized using env MODEL_PARAM_k.

Usage

It has two modes

1. compute --mode intermediate
2. compute --mode aggregate --job-ids 1 2 3

Intermediate mode calculates knn from a single node, while aggregate mode is used after intermediate to combine knn from multiple jobs. Intermediate mode can be also used to calculate knn from single node.
