Can anyone suggest to me how should I gain more in-depth insights about the decision trees, random forests, and XGBoost?
Kaggle deals with them in its various free courses, you can have a look in there. Also if you search you could find literature about them.
Sure thank you so much, just one more thing can you help me with suggesting a great book for the same and further topics as well?
No I haven’t read much books myself…but googling can help
