Hi have dataframe with large categorical values over 1600 categories is there any way I can find alternatives so that I don't have over 1600 columns.
I found this below interesting link http://amunategui.github.io/feature-hashing/#sourcecode
But they are converting to class/object which I don't want. I want my final output as a dataframe so that I can test with different machine learning models? or is there any way I can use the genetrated matrix to train the other machine learning models other than Logistic regression or XGBoost?
Is there anyway I can implement ?
