298 - What is k fold cross validation?

[@newcooldiscoveries5711]

That was very informative. You have both depth of knowledge and a gift for teaching. Thanks.

Thank you Sreeni for all of your great videos. I have a suggestion, since the start of the channel we we have been learning the different ML/DL algorithms and their applications using images. Can you please consider making a series on how to apply them on biomedical signals ? Thank you

Super sir 👍 eagerly waiting for the coding section

[@bitugmasamuel1797]

Please make video on ensemble model on deep learning, where you will need to compile and the out of base models for the ensemble model

[@luthfanhabibi]

Really informative video as I now also learning more about the cross validation. One question, so after doing the cross validation, how we should develop/train the final model?

[@DigitalSreeni]

Please wait for future videos, they may answer your question.

Love your content. Please keep it coming. I have a few doubts and would appreciate @DigitalSreeni/communities thoughts. 1) Don't you think that any preprocessing should be happening within the loop of cv (@ 13.35) to avoid data leakage. Essentially in the loop (say for 5 fold cv) 4 folds are for training and 5th fold for testing. If you normalized/scaled data outside the loop - this should constitute data leakage, right? 2) where to encode categorical features - before split, after split or within for loop? 3) when we want to get the final model for production - we consider the entire data (train + test). All the preprocessing that we have done while doing cv will be executed on this entire dataset, right? i.e. if standardization was used while performing cv now for the final model and for future data preprocessing the mean and standard deviation will come from this (train + test) data, correct?

Sir....can you please upload a separate video related to FEATURE EXTRACTION USING "SURF" Algorithm for image classification?

[@DataAnalytics2486]

Thanks Screeni! I wanna ask if we should removal outliers before split or after the split/cv?

amazing🤩

u the GOAT !!!.... up there with Tom Brady and MJ

[@RoyAAD]

Great videos

[@MovieTheater69]

Thank you very much

[@wg2]

scaling before splitting oops, I think I have made that mistake more than once. 😅

[@DigitalSreeni]

Me too - all the time in my tutorials.

[@Алг-ж3д]

Awesome thanks 😊
