Denis/Yury, I am in favor of the second approach. Also, I envision GA Grid implemented into a separate package within the ML module.
If possible, It seem's the initial priority would be merging GA Grid into the ML module such that it operates independently. Next, we can discuss/prioritize how best other ML algorithms could utilize GA Grid.(ie: implement trainers based on GA Grid as you mentioned) I am not very familiar with 'trainer' concepts in ML but don't see it as an issue. Please advise. Best, Turik -- Sent from: http://apache-ignite-developers.2346864.n4.nabble.com/
