Capstone Project: Error Report and Model Diagnostic
web-development.
Course Modules:
Module 1: Define the Scope of Error Analysis
Choose a domain (e.g., sentiment analysis, fraud detection, medical diagnosis)
Set business priorities: accuracy, safety, fairness, or cost impact
Gather a dataset with clear ground truth and model predictions
Module 2: Identify and Categorize Errors
Generate confusion matrix (TP, FP, TN, FN)
Explore class imbalance, boundary errors, and edge cases
Segment errors by user group, feature, or class type
Module 3: Statistical & Visual Diagnostics
Analyze error distribution using charts and histograms
Compare false positives vs. false negatives
Use SHAP/LIME for interpretability on misclassified instances
Module 4: Root Cause Analysis
Investigate data quality issues (e.g., mislabeled data, missing features)
Review model assumptions and overfitting/underfitting
Test sensitivity to hyperparameters or training data shifts
Module 5: Reporting and Recommendation
Write a structured error report covering:
Key metrics (accuracy, recall, AUC, etc.)
Error trends and critical weaknesses
Suggested improvements (relabeling, rebalancing, new features)
Deliverables:
Jupyter Notebook or Google Colab walkthrough
PDF or slide-based executive summary
GitHub link with reproducible code and charts
Tools & Technologies Used:
Python (Pandas, Scikit-learn, Matplotlib, Seaborn)
SHAP / LIME (optional for explainability)
Jupyter Notebook or Google Colab
Excel or Google Sheets (optional for tabular summaries)
