Re: How to contribute a spatial module to MADlib manipulating objects from PostGIS

2016-01-19 Thread Kuien Liu
Hi Greg,

Is the video replay available for guys outside Pivotal network to watch?
I made a call with Chenliang Wang in 7:15pm~8:13pm yesterday evening, he
explained his case in evaluating the property prices, he is thinking to
implement this function (GWR) inner databases. I explain the usage of
Madlib and how to enable PostGIS in GPDB. I think Gautum's presentation
on BayesianAnalysis is a good tutorial for him to kick-off his plan.

Cheers,
Kuien Liu
