SMOTE, Oversampling on text classification in Python And then use those numerical vectors to create new numerical vectors with SMOTE But using SMOTE for text classification doesn't usually help, because the numerical vectors that are created from text are very high dimensional, and eventually using SMOTE, results are just same as if you simply replicate the exact samples to over-sample –
Oversampling: SMOTE for binary and categorical data in Python Then, using SMOTE we take 2 samples where one has category 0, and the other has category 2, and we end up interpolating such that the rounded value is 1 The final result would be that we have a generated data sample classified in the 'Car' category whereas the parents belonged to Women's Clothes and Women's Shoes, which is totally meaningless
Xgboost with Smote on imbalanced data - Stack Overflow attached is the code for xgboost on ftir data with smote and smote_weights the results based on smote is attached as image From the confusion matrix, i understood that even after applying smote, class 0 is not being utilized in any fold
The right way of using SMOTE in Classification Problems In general, you want to SMOTE the training data but not the validation or test data So if you want to use folded cross-validation, you cannot SMOTE the data before sending it in to that process No, you are running SMOTE twice (before and inside the pipeline) Also, you have SMOTEd points in the validation folds, which you don't want
How to perform SMOTE with cross validation in sklearn in python I have a highly imbalanced dataset and would like to perform SMOTE to balance the dataset and perfrom cross validation to measure the accuracy However, most of the existing tutorials make use of only single training and testing iteration to perfrom SMOTE Therefore, I would like to know the correct procedure to perfrom SMOTE using cross

AttributeError: SMOTE object has no attribute _validate_data It would give you AttributeError: 'SMOTE' object has no attribute '_validate_data' if your scikit-learnis 0 22 or below If you are using Anaconda, installing scikit-learn version 0 23 1 might be tricky
python - Scikit Learn Pipeline with SMOTE - Stack Overflow I would like to create a Pipeline with SMOTE() inside, but I can't figure out where to implement it My target value is imbalanced Without SMOTE I have very bad results My code: df_n = df[['user_
nlp - Using SMOTE for BERT inputs - Stack Overflow Yes, the general solution for the sentence classification tasks is to use the hidden vector representing [CLS] as sentence representation You can use SMOTE to sample from [CLS] vector space, but that means you won't be able to fine-tune the transformer body of BERT, because there won't be any specific input for synthetic vectors –
How to balance unbalanced classification 1:1 with SMOTE in R library(DMwR) smoted_data <- SMOTE(targetclass~ , data, perc over=100) I have to admit it doesn't seem obvious from the built-in documentation, but if you read the original documentation, it states: The parameters perc over and perc under control the amount of over-sampling of the minority class and under-sampling of the majority classes
