Subject Re: Learning with sparse vector format data
Date Thu, 19 Jul 2018 18:46:54 GMT

Hi MADlib User Community,


I am new for MADlib. I have a question regarding the data in sparse vector format -  Can I
run the learning in sparse vector format?

For example, logistic regression. Seem the parameters assume that the data was stored in the
table.

In my scenario, I have 10 thousand if features, so that store them in the sparse vector format
would be a better solution.



Thanks,

Luyao
