Weighting for Multiclass Classification Problem

Weighting for Multiclass Classification Problem



I was just wondering if there was any way to apply weights to classes within a multiclass project or possibly down sample specific classes. I know you can apply these techniques to binary classification problems but I have an 8 class problem and I would like to reduce the occurrences/impact of the majority class but am unsure if this is possible?

Hey @oscarjung, looking at the DataRobot docs on Smart Downsampling and Feature Impact, Datarobots down sampling feature is just for Binary Data. I'm working on a similar problem right now, if your interested I'll post how I got round the issue.  

Thank you @IraWatt ! I would be interested to see how you did it cheers
