GridSearchCV | Hyperparameter Tuning | Machine Learning with Scikit-Learn Python

In this Scikit-Learn learn tutorial I've talked about hyperparameter tuning with grid search. You'll be able to find the optimal set of hyperparameters for any machine learning model using this method!

Thanks. Nice video. But why are you doing GS.fit (X_train, Y_train) when you already have cross validation with cv = 5. Shouldn't you just do GS.fit (X, Y) ?

[@lukehamilton8285]

you should train on x_train and y_train because this allows you to further test the model once the optimal hyperparameters have been found with an unseen test set which the model has not seen stopping data-leakage

[@jessemutiga6055]

there'll alway be a random indian out there who will help you get your assignment done on time.

[@NormalizedNerd]

lol...at least you are not outsourcing your assignments!

[@krimsonsun10]

DUDE!!! You are the Guru among common minds. This was the best explanation ever. Simple succinct and easily understandable for a newbie like me. I also like you give extra homework, and nuggets of knowledge related to the topic that I can look into afterwards. Now time to study the rest of your videos 👍⭐⭐⭐⭐⭐

[@shwetabhat9981]

Hope you are doing well sir . Kindly continue your video series as it greatly helps and is just amazing!! 🙂

[@philipbutler]

I learned about grid search for a course last semester, it was for a final project on sklearn that I waited to start 3 days before it was due, so I rushed to learn a lot of concepts that I promised myself I’d go back and understand more thoroughly (and probably will need to for upcoming courses/career). So this was an awesome refresher on this topic! Love your videos, keep up the great work!

[@NormalizedNerd]

Thanks mate! It's always useful to revisit an old topic.

[@ZirothTech]

Great video, thanks again!

[@NormalizedNerd]

Glad you enjoyed it!

[@bassamdaou2908]

Thank you. Please can you make a video explaining how we can make prediction from different regression models: regression tree, random forest, artificial neural network, SVM, Bagged CART, Generalized boosting, Extreme Gradient boosting

[@ikramed]

Random state why = 2021

[@chongzhang871]

What about the the testing data? It seems u have not used them.

[@raselsheikh5800]

This is my first comment at youtube. I came here because of your video quality and realize your explanation also fanstastic. I think you are using manim. For me it's a great chanel.

[@NormalizedNerd]

Welcome to my channel! I'm really glad you that liked my content :D :D
Yes, I use manim.

[@onestopzz6446]

Bro, even without hyper parameter tuning, I am getting more than 0.99 r2_score. But I am getting 0.96 r2_score with tuning. So how exactly this tuning is helpful?

[@achin_sharma]

it means default values are best fit for your dataset

[@MessiasBatista]

Hello, congratulations for video.
I have a question. You have a example that discovers the best hyper-parameters using Swarm Intelligence?

[@anurajms]

ty

[@fosheimdet]

From now on, I identify as a person from the future😊

[@Junistz]

Thanks for your video it is going to help me ! :D
Invalid parameter "max_depth " contains whitespace.
I got error kind of this ..

[@tinanajafpour7214]

thank you for the video it was really helpful. I had a question, could you please help me? when I want to download data from kaggle, I receive 403 forbidden Error!

[@viniciuslazzeri3019]

Amazing! How can I implement this on fastercnns?

[@mikeboudhabhay6082]

thanks for your work and dedication . your vid is very useful for my final project in DS bootcamp.

[@jamalnuman]

great

[@amirhosseinrahimi3964]

Thanks, one queation, after tuining the model and finding the best hyper parameter, is it necessary to run the model with found best parameter for moel training right and prediction? i mean after using GridSearchCV, model is already configured by best parameter? can you please elaborate?

[@ramblingsofadegenerate1174]

Recently found your channel very grateful

[@samikshakolhe5086]

Awesome Explaination! appreciate your work and subscribed;)

[@madstolyar]

How does GridSearch work with pickeld data?

[@excursion5246]

thanks. Can you make a video about deep neural network regression predictions. Like multiple inputs and one output prediction by using this gridsearch. Thanks a lot.

[@yusufpradanaajisurya9176]

Thank you!! This is the best video on this subject!

[@idrissjairi]

thank you so much for the great video

[@grumpy_techo]

I have just stumbled upon you channel. you videos are well communicated. Well done. Another good video could be - how do you settle on a model that is generalised to test data.

[@shoaibsh2872]

I knew about grid search, but in the end the technique you shared was new to me and it will be really helpful in the future when I'm going to use grid search, thank you for sharing. Great vid as always 😊

[@NormalizedNerd]

Yeah that's really helpful.

[@cvrbcheppali8214]

Very nice and one of the best video on Hyperparameter Tuning

[@antonellars22]

Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@LeE-yr7lp]

Could you do a video about boosting models please? Thanks

[@PythonArms]

Great video. thank you

[@10955356]

amazing video my friend!

[@karlopoljancic]

Thanks! Gonna try this out!

[@lukehamilton8285]

great video helped me alot!

[@736939]

Where are you? We miss you :(

[@parulkhattar28]

1:53 -> 2D arrays not lists 😀

[@cyberpunk_edgerunners]

thanks ， my friend

[@saurabhjoshi8776]

keep up the good work..😀

[@collinspo]

Great content. Thanks

[@rijwanapatel6942]

Hey buddy how old are your 😁

[@harshavardhanm9481]

Nice, clean animations 👍

[@tomliao6667]

thanks for sharing especially for the last part that how to choose an efficient model with low computer resource wasting haha

[@NormalizedNerd]

Glad it was helpful!

[@nachomacho7027]

Thank you bro

[@gouthamansaravanan7692]

Best one! Thanks!!

[@deniskoala3131]

Thank you for this beautiful work.
I have a question: what happens if we run the same code several times? Will the best_estimator always be the same?
Thank you for your answer.

[@tomliao6667]

if you keep random_state the same number, I guess there will be the same best_estimator

[@ganeshnaik6503]

This is awesome. Thanks!

[@krepker]

Awesome video. tnx man!!

[@NormalizedNerd]

Thanks mate!

[@kolboy2028]

which software do you use for your animation?

[@NormalizedNerd]

I used manim for intro animation

[@kolboy2028]

@@NormalizedNerd and for the rest of the video?

[@bzaruk]

Great vid! Thanks!

[@NormalizedNerd]

Thanks mate! :D
