Objectives
- Categorical Data Handling: Master CatBoost’s unique "Ordered Target Statistics" to process high-cardinality features without manual one-hot encoding.
- Performance Optimization: Implement Symmetric (Oblivious) Trees and GPU acceleration to build models that are significantly faster at inference time.
- Regularization Techniques: Apply advanced hyperparameter tuning for l2_leaf_reg, random_strength, and bagging_temperature to eliminate model overfitting.
- Production Deployment: Learn to use the Model Analyzer for SHAP values and export models to C++ or Python for high-throughput production environments.
Pre Requisites
- Basic Python Proficiency: You should be comfortable with Python syntax, specifically working with lists, dictionaries, and basic function definitions.
- Foundational Data Science Knowledge: Familiarity with the general machine learning workflow (training/testing splits, overfitting vs. underfitting).
- Library Fundamentals: A basic understanding of the Scikit-Learn API or NumPy/Pandas will help you navigate the data structures used in the course.
- No Prior CatBoost Experience Needed: We start with the core architecture, making this accessible to anyone transitioning from XGBoost or LightGBM.
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!
