Would you please launch the third part of "XGBoost Regression" ? I hope can learn from you about hyperparameter tuning and how to find out the best prediction method. Thanks!
Is there another part? Really enjoyed it.
Excellent video. Please keep it up. Thank you. Are yo able to create a video for Nomogram for customer churn? Best wishes
Thank you!! I'll create more content for sure. Customer churn is important.
the video in not visible to me Could you make it visible Sir?
xgb_model.fit(train_x, train_y) when i run this all the hyperparameters come out as none or false what should i do

You could read the empty columns then run janitor::remove_empty() to remove all empty rows and columns.
Very interesting topic, and very informative tutorial. 1. You could scan and catch errors by eye 👁 in a small data set. You need to relay on functions or formulas to hunt errors in a reliable and efficient way. 2. Changing chr to numeric. Why doing it by observation not by column? This is one would be straitfoward. df$colx <- as.numric(df$colx) # colx is column name
Hi Afonso. Thanks for your interested comment. Yes, Indeed the approach works for small datasets. Changing observations only was to eliminate some null values that sometimes make impossible to apply directly as.numeric into a column.
please put the video for part 3.
Thanks Mathi. We'll do it!!!
hi,can you do part 3 immediately please, we really need it @@RVStats_ENG
can you help me how to handle nonlinear relationship between features and target variable in Machine learning predictive models
Hi Tajiri. Thanks for your comment. Well, for non linear relationships you could try decision trees, random forest, XGB and as well as Support vector machine. However, you have to elaborate more your question to help you better. Best regards

Hi Rudy!! Thanks for your comment.
how fix Error in library(ggradar) : there is no package called ‘ggradar’ ?
Hi Muhammad. You have to run: devtools::install_github("ricardo-bion/ggradar", dependencies = TRUE)
Thank you very much my friend!! Regards from Chile!
Hi Rafael!! Thanks so much for your kind comment. Saludos cordiales!
print(r2_score(y_train, pred_train)) = .9880135 print (mean_squared_error(y_train, pred_train))= 490.749 model.score(x_test, y_test) = 0.88860 print (mean_squared_error(y_test, pred)) = 3193.4547 will you please tell me what does it mean ?
Hi Dheeraj. Here we can see that your train R^2 is nearly perfect and your test R^2 is below 0.90. This is clear indication of overfitting because your model is working really well in the training data set but for unknown values (test data) is performing good, however not close to training. You also can see in the huge difference of the errors for MSE.
Thank you so much for this video.
Thanks so much for your opinion. hope you like more of my videos.
hey , my accuracy is around 0.96 for my data and MSE error is high too, what should I do to improve the accuracy and reduce error?
Hi Piyush. We need to compare between test and train performance to know what is the next step. 0.96 is for train ?? MSE could be high is we are talking about dependent variable with big magnitude (example million of dollars).
your channel is very underrated mate , keep it up i am your new sub. It would be great if you can upload video on working on project from scratch in linear , logistic and other r stuido algorithms.
Hi Parth. Thank you so much for your comment and suggestion. I'll keep posting more about it.

Great video! One small thing: x_text.loc[0] shows the persons information, but predictions[1:10] doesn’t include this person since Python is zero based indexing. Or am I wrong?
Hi Henrik. Thanks for your question and comment. Indeed, x_test.loc[0] displays all the information because it's an observation from a dataframe, predictions[1:10] on the other side only, displays the category (labels) given from the output of the model. Best regards
