-----------------------------------------
Hi [~yu_ishikawa],
Have you started working on it ? I see no activity here from 22 july. If you
don't mind can we take up the implementation.
[~bgawalt] What are your thoughts on it.
> k-Nearest Neighbor classification and regression for MLLib
> ----------------------------------------------------------
>
> Key: SPARK-2335
> URL: https://issues.apache.org/jira/browse/SPARK-2335
> Project: Spark
> Issue Type: New Feature
> Components: MLlib
> Reporter: Brian Gawalt
> Priority: Minor
> Labels: features, newbie
>
> The k-Nearest Neighbor model for classification and regression problems is a
> simple and intuitive approach, offering a straightforward path to creating
> non-linear decision/estimation contours. It's downsides -- high variance
> (sensitivity to the known training data set) and computational intensity for
> estimating new point labels -- both play to Spark's big data strengths: lots
> of data mitigates data concerns; lots of workers mitigate computational
> latency.
> We should include kNN models as options in MLLib.
