PSO showing error "incompatible number of attributes (821! = 4260)!"
I am using RM for the sentiment analysis of the movie review dataset. i have tokenised the sentiments and have calculated the term frequency and TF-IDF for the words. for classification want to use 10-fold cross validated SVM-PSO but after 11th execution the tool returns the error "incompatible number of attributes (821! = 4260) !".
