    Introduction

    What is Advanced EDA? Pair plots, correlation heatmaps, target analysis, and leakage checks. Machine learning systems learn patterns from data instead of hard-coded rules.

    Understanding the topic

    How Advanced EDA works:

    • Pair plots, correlation heatmaps, target analysis, and leakage checks.
    • Prepare or explore data as needed.
    • Train or apply the model/technique.
    • Evaluate results and iterate.

    Step-by-step explanation

    1. Understand — Learn when and why to use Advanced EDA.
    2. Prepare data — Load, clean, and split datasets.
    3. Apply — Fit model or run algorithm in Python/sklearn.
    4. Evaluate — Measure accuracy, loss, or cluster quality.

    Best practices

    • Split data into train/validation/test before tuning.
    • Scale numeric features when algorithms are distance-based.
    • Always evaluate on held-out data — not training accuracy alone.

    Common mistakes

    • Training on test data (data leakage).
    • Ignoring class imbalance in classification metrics.
    • Using accuracy alone on imbalanced datasets.

    Summary

    Advanced EDA is a core machine learning topic. Pair plots, correlation heatmaps, target analysis, and leakage checks
