Hi Krish me and my team working on cloud cost forecasting problem for our organization we have five different vendors azure,aws , snowflake, Databricks,gcp databricks can make videos on this how cloud costs works because we are facing challenges like that we have very less quality data of 6 months each of them CSV file which includes daily based data @krish

7:22 Aren't we supposed to use X_train and Y_train instead of X and y in the parameters of cross_val_score function?

cross_val_score function doesn't require separate training and test sets to be explicitly defined. Instead, it handles the splitting internally based on the cross-validation strategy you provide

Sir for the imbalanced Dataset, can't we first handle the imbalance and then do KFold test?
@shubhamchoudhary5461

Sir , in machine learning suppose if the model is overfitted & we apply k-fold cross validation on top of that model k-fold(10) , then we get to see lots of variation in cross validation scores right ?. Such as Score = [ 40, 80 , 70 , 80 , 50 , 83.2 , 81,84 ,.......] Means , here diffn between highest & lowest accuracy is ( 84 - 40 = 44) which is very high , means our model is overfitted & not capable to perform on unknown data situation , hence we need to regularise it &do hyperparameter tuning . Make me correct .. Thank you!!!!..

Thank you @Krish for such a great explanation. I have a question, cross_val_score(model, X, y, cv = k_fold_validation) we are passing X and y from original data without using training data. We also assume that X and y have missing values. If we do imputation on X and y, is there any data leakage problem in cross-validation? if it is how could we handle it?

It is important to keep in mind that cross-validation is not a way to build a model that can be applied to new data. Cross-validation does not return a model. When calling cross_val_score, multiple models are built internally, but the purpose of cross-validation is only to evaluate how well a given algorithm will generalize when trained on a specific dataset

@nishikantgurav4500

krish, in k fold cross validation code you passed directly X and y without splitting so how can the model will know what will be the percentage of training and testing data? cv=10 will take 10 random_states that is each random state is having different data that will give 10 different accuracies. But my question is that how can the model know the percentage of splitting? Is we have to split data with train_test_split giving percentage of splitting and then cross validate with cv=10? please help in this.

Yes, my knowledge suggest the same. I think it is due to data leakage. I learnt as you should keep test data until the very end (final prediction).
