ML Reliability & Efficiency Toolkit

A modular toolkit for Responsible AI auditing and LLM context optimization.

This project explores methods to improve machine learning reliability, fairness, and efficiency by combining:

• Responsible AI auditing
• Data leakage detection
• Model evaluation visualization

The goal is to create practical tool that students can integrate into ML pipelines.

1. Is the model treating demographic groups fairly?
2. Did the model learn anything it shouldn't have (data leakage)?

Project Motivation

In many machine learning workflows, model development focuses heavily on accuracy. However, several important risks are often overlooked.

Bias and Fairness: Models can perform differently across demographic groups. Without proper auditing, these disparities may go unnoticed until they cause harm.

Data Leakage: Models can achieve artificially high performance by accidentally learning information that would not be available at prediction time, leading to failures in production.

LLM Context Inefficiency: (Riddick Input)

Methodology

Each module follows a consistent evaluation approach:

1. Define formal metrics
2. Apply thresholds for interpretation
3. Generate structured outputs
4. Integrate results into a unified dashboard

This ensures that results are comparable across modules, interpretable, and actionable.

Datasets

Tabular — Fairness Auditing and Leakage Detection

Adult Income Dataset (UCI ML Repository): Predicts whether an individual earns more than $50,000/year. Attributes include age, education, occupation, marital status, race, and gender. Used for fairness auditing and subgroup analysis.

German Credit Dataset: Predicts whether an individual represents a good or bad credit risk. Attributes include age, gender, employment status, credit history, and loan amount. Used for fairness evaluation in financial decision systems.

Synthetic Leakage Dataset: Generated to simulate controlled leakage scenarios including a feature directly encoding the target, future information in training data, and train/test duplication. Used for testing and validating the leakage detection module.

Modules

1. Fairness Audit

Evaluates model behavior across demographic groups.

• Computes fairness metrics (e.g., equal opportunity difference, demographic parity ratio)
• Performs subgroup performance analysis
• Flags disparities using defined thresholds

For metric definitions, thresholds, and evaluation criteria, see fairness_audit/README.md.

---

2. Data Leakage Detection

Identifies potential sources of leakage in datasets and ML pipelines.

• Detects features strongly correlated with the target
• Identifies train/test contamination
• Highlights high-risk features

For detection methods, risk levels, and evaluation criteria, see leakage_detection/README.md.

4. Visualization Dashboard

Interactive Streamlit application that displays:

• Fairness metrics and subgroup comparisons
• Leakage risk reports
• LLM experiment results
