Siddhardhan, very good explain everything.Thank you

[@Siddhardhan]

😇😇

Sir, your way of teaching is excellent, i don't have any words to tell you about your teaching and presentation, Please go through all machine learning models with Maths from Scratch, and if possible, make 3 or 4 more case studies on every model that your build from scratch. thanks, thanks a lot......

8:20 Hello Sir, why are we inserting the targets to X_train?

[@alirezamarahemi2352]

The problem with the model you have created lies within the following lines of code: for data in neighbors: label = [] label.append(data[-1]) It should be changed in this way: label = [] for data in neighbors: label.append(data[-1]) The list of labels gets empty in every iteration. If you apply the change, your model's accuracy will be 72% just as exact as the KNNClassifier in sklearn library.

Amazing!

Sir, can you please do a tutorial on machine learning algorithm to predict bus arrival time

[@OmkarPrajapati-j5v]

i get an error that KNN_classifier() takes no arguments.pls help

[@AHMADKELIX]

permission to learn sir. thank you

[@charugullasanthoshkumar2870]

can you please help me with seperating features and target how to split them???

[@vijayramaraju3522]

Sir Please Continue Videos (Tutorials)

[@sandys4009]

Sir can u please do a prj on real face emotiin from the scratch

[@nguyentrunguc12]

Can you turn on translated subtitles. Thank you!

[@piyushpathak7311]

Sir please upload full videos of xgboost and DBSCAN, ensemble learning algorithms,trees algorithm with detailed explanation and implementation plz 🙏 sir

[@Siddhardhan]

yeah. sure

Getting error:- 'KNN_classifier' object has no attribute 'distance_metrics'

remove the s at the end or check if you have named it something else
