I used this module a lot during my work. thank for these great free libraries, it make data scientists easier. Most of work is to glue the data to these libraries.
Great video. Just to clarify, is the purpose of cross-validation to tune the hyperparameters of models on a variety of different train_test splits to avoid overfitting? Cheers!
Yes, the main purpose of cross-validation is to estimate the performance of a model on an independent dataset and to tune the hyperparameters of the model to avoid overfitting.
Good post. By the way, how do we select the best model after cross-validation? I am more interested in regression than classification. Have you tried using a multivariate polynomial regression model so that we could establish an empirical relation?
how to print roc curve for overall cross validation? i have been trying to print roc curve but it shows me error apparently because i got different counts of tprs/fprs on each fold that prevents the code from showing
Before doing a crossvalidation, shoudn't you use a dimentionnality reduction technique to determine if all features are necessary for your training? Thanks by advance if you take the time to answer me!
nice video, one silly question u are using in a pipeline minmaxScaler how does know the cross_val_score to apply minmax_score on X_array? I know it's silly question about I have the question because u don't transform your pipeline to X_array
Hi, great video series. Can you start a video series about medical image processing and ML like 3D MRI processing, stopping leaky validations and etc. It would be really useful because there aren't many resources.
Hi sir, i have been trying to implement video classification using CNN. All the content or tutorials out there are quite hard to implement or maybe I got used to your detailed explanation. Please do a tutorial on how to load video data. Thanks for all the high quality content.
You are one of the best data science teacher out there. Thanks for your good work and approach. You explain very well on a wide range of topics.

Been enjoying this KFold series. Looking forward to the next one. Thanks.

Thank you very much.
Dear Sreeni, thank you so much for your work! Have a good one!

Hi Thanks for the video.Code Generated is not in the github file you shared
