Learn how to clean and prepare raw data for Artificial Intelligence models in this Class 11 Artificial Intelligence (CBSE Code 843) lesson!
We’ll explore the steps of Data Preprocessing including handling missing values, outliers, inconsistent data, and duplicates, making your dataset ready for accurate model building.

📌 What You’ll Learn:
✅ Data Cleaning → Fix missing, wrong, and duplicate data
✅ Data Transformation → Convert text to numbers, create new features
✅ Data Reduction → Reduce dataset size/features for efficiency
✅ Data Integration & Normalization → Merge sources + scale values equally
✅ Feature Selection → Keep only the important data for modeling

🔧 Python Tools (if coding included):
✔ Pandas – Handle missing & duplicate values
✔ NumPy – Work with arrays & data transformations
✔ Scikit-learn – Scaling & feature selection basics
