[REPORT] MADlib - April 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.  Key features are PostgreSQL 11
support,
a new method for k-NN nearest neighbors, and an early stage implementation
of deep learning.

- After that will be the 2.0 release with JIRAs related to versioning
models.

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

- Frank McQuillan also presented at PostgresConf 2019
March 18-22, New York on AI from model perspective
