Dealing with Imbalanced Datasets

 ⚖️ Dealing with Imbalanced Datasets

📉 Improve Model Performance When Data Isn’t Fairly Distributed

📚 What You’ll Learn:

What is an imbalanced dataset?

→ When one class significantly outweighs the others

Why it causes problems in classification models

Key challenges:

Misleading accuracy

Bias towards majority class

Poor recall/precision for minority class

🛠️ Techniques to Handle Imbalance:

Data-Level Methods:

Oversampling (e.g. SMOTE, ADASYN)

Undersampling

Synthetic data generation

Algorithm-Level Methods:

Class weighting

Cost-sensitive learning

Evaluation Metrics:

Precision, Recall, F1-score

ROC-AUC vs Accuracy

🧠 Ideal For:

Machine Learning Practitioners

Data Science Students

Anyone working with real-world classification problems
