Subject Re: Learning with sparse vector format data
Date Fri, 20 Jul 2018 21:56:42 GMT
Hi Luyao,

Thanks for trying out MADlib. Most of the modules including logistic
regression do not support sparse vector columns. However kmeans
http://madlib.apache.org/docs/latest/group__grp__lda.html does support it.

Let us know if you have more questions.

Thanks,
Nikhil Kak
