Objectives
- Master Core Architecture: Understand Oblivious Trees, Symmetric structures, and the Ordered Boosting algorithm to prevent data leakage and prediction shift.
- Automated Feature Engineering: Learn how CatBoost handles high-cardinality categorical data, missing values, and text/image features withoutmanual preprocessing
- Hyperparameter Optimization: Gain the skills to tune learning_rate, depth, l2_leaf_reg, and utilize the Overfitting Detector for peak model performance.
- Production & Deployment: Implement model explainability with SHAP, utilize GPU acceleration, and export models to C++, JSON, or CoreML for low-latency inference
Pre Requisites
- Basic Python Proficiency: You should be comfortable with Python syntax and data structures (DataFrames, Lists, Dictionaries).
- Machine Learning Fundamentals: A foundational understanding of supervised learning, specifically classification and regression concepts.
- Scikit-Learn Familiarity: Previous experience with basic ML workflows (train-test split, fit/predict) is helpful but not strictly required.
- No Prior CatBoost Experience Needed: We start with the core mechanics and move to senior-level architectural questions, making it accessible for all levels.
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
