IGNITE-10698 Task
Hello everyone, I've fixed codestyle issues in my branch and got "No possible blockers" in TC bot, so PR is currently ready for review. PR github link: https://github.com/apache/ignite/pull/7394 Jira task link: https://issues.apache.org/jira/browse/IGNITE-10698 TeamcityBot link: https://mtcga.gridgain.com/pr.html?serverId=apache=IgniteTests24Java8_RunAll=pull/7394/head=Latest
[ML] Tickets for beginners
Hello everyone I'd like to take following task: https://issues.apache.org/jira/browse/IGNITE-12384?jql=project%20%3D%20IGNITE%20AND%20status%20in%20(Open%2C%20Reopened)%20AND%20component%20%3D%20ML%20AND%20labels%20%3D%20newbie But I do not fully understand what exactly needs to be done. As far as I understand encoders are needed to convert categorical variables to numerical. So, to demonstrate how they works I need some dataset with several categorical features. Should I search for it or generate by myself? Then, do I need to solve some regression/classification problem in order to demonstrate "power" of using categorical variables to fit prediction or classification models?

Old annotations are present and new > annotations don't exist yet :) I talked about implementation of methods *getDescription* / *getParameterName* in *IgniteStandardMXBean *class. To support backward compatibility I need to check if there are old annotations above method, or new one before parameters. So, my question was the order of searching annotations (first - old, after - new). вт, 4 февр. 2020 г. в 21:10, Andrey Gura : > > Andrey, then I suggest firstly check if old annotations are present, and > if > > not - are there any new annotations.

Re: Contribution
Andrey, then I suggest firstly check if old annotations are present, and if not - are there any new annotations. Do you agree? And should I also replace usage of old annotations or leave it as it is? вт, 4 февр. 2020 г. в 16:57, Andrey Gura : > Lev, > > > I'm confused about your first comment.

Re: Contribution
Thanks for answer, Andrey. I'm confused about your first comment. Does it mean, that the only thing I can do is to create new annotation? Because, as you said, I must leave unchanged all related to old annotations functionality. So, I can't change implementation of *getDescription / getParameterName (MBeanOperationInfo op, MBeanParameterInfo param, int seq)* methods from* IgniteStandardMXBean* class, and replace current annotations with new one. вт, 4 февр. 2020 г. в 14:28, Andrey Gura : > Hi, Lev! > > I think you understand task correctly. > > A couple of comments: > > - Existing annotations and related functionality must not be deleted > because it is part of public API and we committed to have stable API > between major releases. > - I would suggest introduce @MXBeanParameter annotation instead of > @MXBeanParameterInformation.

Hello everyone, I have question about following task: [https://issues.apache.org/jira/browse/IGNITE-10698] Solution proposed in task description is seem to be logical. So, I need to every replace @MXBeanParametersNames and @MXBeanParametersDescriptions (everywhere, for uniformity) with something like: void methodName(@MXBeanParameterInformation(name = "name", description = "description") firstParameter, ...) {}. And, of course, need to change processing logic at getParameterName/getDescription methods from IgniteStandardMXBean. Do I understand correctly what needs to be done?
