Is it feasible to use trained and saved models on new data to predict sentiment ? I am building a model using SVM technique on some text data to predict sentiments and saved it. Then when I use the predict function to predict sentiments on the new data it is throwing an error saying - #Error in predict.svm(X[[1L]], …) : test data does not match model !
The new data will have slightly different group of words and will not match exactly with the words group that was used to train the model. Am I making sense?
