I want to split my whole dateset to training set and test set, building model in training set, and validate model using test set. Now, How can I split my dataset to them reasonally. Please give me a hand, It is better to give me some R code.
and I see some ways like using SOM to project whole independents to 2-dimensions and find some to be training set and others are test set. like below. I also want to do this. and my date is in xls accessory. Please help me. and excel file is 218*47 matrix, 47 are indepents. I want to project it to 2D and label the corresponding sample label like that picture below. thank you! http://n4.nabble.com/file/n976245/SOM%2Btraining%2Bset%2Band%2Btest%2Bset.jpg SOM+training+set+and+test+set.jpg http://n4.nabble.com/file/n976245/matlab218x47.xls matlab218x47.xls -- View this message in context: http://n4.nabble.com/Help-Suggest-me-some-methods-to-identify-training-set-and-test-set-tp976245p976245.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
