Subject Re: [jira] [Commented] (MAHOUT-1929) Add Generalized Linear Models
Date Mon, 10 Jul 2017 18:05:05 GMT
@rawkintrevo, I'm finally getting time to now building back the GLM infrastrucure into mahout
and wanted to work with you to push this forward, I have created this class:
in my branch and wanted to discuss how we can incorporate this into the Regression class hierarchy
that you've created, please ignore the missing license etc, I will add that back in when we
can get a plan together on this.

Let me know your thoughts on how to proceed forward with this.

Also at Strata- thanks for reaching out a second time- totally missed your
first message.

I'll check this out tomorrow on the flight home. We can set something up
from there.  Thanks for the contribution!!
