[REPORT] MADlib - January 2019

["FENG, Xixuan (Aaron)" <xi...@gmail.com>]

## Description:

- Apache MADlib is a scalable, big data, SQL-driven machine learning
framework
  for data scientists.


## Issues:

- There are no issues requiring board attention at this time.


## Activity:

- Last release was 1.15.1 which was the 5th release as an Apache TLP
project.
  This was a minor release that included support for Ubuntu 16.04 as well as
  various feature improvements.

- Community is at work on the 1.16 release which is anticipated in the next
  month or so.  Key features are PostgreSQL 11 support, and a new method for
  k-NN nearest neighbors.

- Community is also at work on the 2.0 release at the same time, with good
  progress on a JIRA related to versioning models.

- On 2018-Oct-30, Nandish Jayaram (MADlib committer) and Frank McQuillan
(MADlib committer and PMC member) visited Arun Kumar, Assistant Professor of
 Computer Science and Engineering at the University of California, San Diego
 regarding possible collaboration projects related to in-database machine
 learning. Discussions went well and we will report back to the community if
 this collaboration moves forward. Note that Professor Kumar is a former
 colleague of MADlib PMC Chair Aaron Feng when both were at the University
of
 Wisconsin-Madison.

— Frank McQuillan (MADlib committer and PMC member) will be presenting at
  FOSDEM’19 on 2019-Feb-03 on deep learning on parallel databases, using
  MADlib and Greenplum Database as an example.


## Health report:

The community is relatively small but very engaged with robust mailing list
traffic, interest in doing frequent releases and new functionality being
developed by contributors.

The number of developers actively contributing to the code/documentation is
approximately 6 in the 4th quarter of calendar year 2018.

We will constantly be on a lookout for new community members to be invited
