Such an impressive video! You explained everything so simply and clearly, taking the viewer from the basic concepts in the beginning to the details at the end. This is one of your best. Amazing.

[@TheTeenInnovator]

Thank you so much Cheni! Always appreciate the support 😎

[@user-ic8oq5dc2c]

I watched the whole thing! So good!

[@amirhrcrash]

Thanks mate, it helped a lot !

[@TheTeenInnovator]

Of course!

At 14:42 I think the name of the function should be Manhatten distance as you had summed the differences and then squared rather than summing up the square of differences.

I'm taking a machine learning course with datacamp and it's stupid because they go over everything like you already know it. I really appreciate what you're doing but can you go into details about the core stuff especially the classifications. y_train, x_train, ...etc are stuff that I can't understand yet. Could you show us why things are the way they are in your code this will help us overcome the barrier of making sense of it all. Thanks.

Great video, quick question... Let's say if want to predict based on age equals 35, salary equals $80,000 what is function to predict whether or not a paper buys the phone? Thank you

[@fr.nijoantony2270]

mode(labels).mode[0] showing error

[@whimsicalvibes]

Thanks for the great video. It made me start using Kaggle and more of seaborn. You did not do the Euclidean Distance correctly, due to a missing brackets in step 10. Correct euclidean distance is 5.385

[@TheTeenInnovator]

I appreciate the comment! I noticed that I made an error in the way I calculated Euclidean distance a while back, just updated the repo!

[@dingyomnivore]

I get error euclidean_distance() missing 1 required positional argument: 'pt2'

[@davidzepeda3071]

"name 'train_test_split' is not defined" I seem to get this error when running it. There was nowhere else it was called before.

you need to import a package from sklearn

[@user-df3zg8ie6f]

I get an error when i use the accuracy function passing the y_test and y_hat_test arguments "Found input variables with inconsistent numbers of samples" do you know what is the problem? Thanks alot!

[@HAsmaa-zg6rt]

happened to me too. seams that X and Y should have the same amount, i did X.shape found : 13,1101 Y.shape found : 1101 I still can't solve it.

[@vishvpatel3269]

i have faced this error please help me " euclidean_distance() missing 1 required positional argument: 'pt2' "

[@rammiokal]

i got the same problem lol

[@tilakbhattacharya9184]

same

[@ashokjayam3231]

can you explain with using functions please

[@TheTeenInnovator]

A function is a way to execute lines of code using a single command without repetitively running the same code over and over, I suggest looking here: www.programiz.com/python-programming/function#:~:text=In%20Python%2C%20a%20function%20is,and%20makes%20the%20code%20reusable.

[@CB_2023]

I keep getting this error: TypeError: KNN() got multiple values for argument 'k_val' Any ideas on how to fix it?

[@TheTeenInnovator]

If you send me your code I can take a look, you can send it to [e-mail]

[@CB_2023]

@@TheTeenInnovator Done! And thanks for the reply. :)

[@faracullaazizli8954]

Pls tell the reply , how to get rid of this .

[@grandhibaladurgasaikrishna7268]

it is better if you have added source code please add it !!

[@TheTeenInnovator]

It is on my GitHub NoamYakarOfficial!
