Re: How to implement multinomial logistic regression(softmax regression) in Spark?
Hi DB, Thanks for your reply, I saw the slide in slidesshare, and I am studying it.

Did I describe the problem not clearly? Is anyone familiar to softmax regression? Thanks.

Hi Cui You can take a look at multinomial logistic regression PR I created. https://github.com/apache/spark/pull/1379 Ref: http://www.slideshare.net/dbtsai/2014-0620-mlor-36132297 Sincerely, DB Tsai --- My Blog: https://www.dbtsai.com LinkedIn: https://www.linkedin.com/in/dbtsai On Fri, Aug 15, 2014 at 2:24 AM, Cui xp lifeiniao...@gmail.com wrote: Did I describe the problem not clearly?

Re: How to implement multinomial logistic regression(softmax regression) in Spark?
DB, Did you compare softmax regression with one-vs-all and found that softmax is better ? one-vs-all can be implemented as a wrapper over binary classifier that we have in mllib...I am curious if softmax multinomial is better on most cases or is it worthwhile to add a one vs all version of mlor as well ? Thanks.

Re: How to implement multinomial logistic regression(softmax regression) in Spark?
Hi Debasish, I didn't try one-vs-all vs softmax regression. One issue is that for one-vs-all, we have to train k classifiers for k classes problem. The training time will be k times longer.
