Understanding Explainable AI (XAI)
XAI, or Explainable AI, changes the game for neural networks by making their decision-making processes clearer. Traditional neural networks are often seen as black boxes, but XAI focuses on providing explanations. Key methods include:
- Feature Selection
- Mechanistic Interpretability
- Concept-Based Explainability
- Training Data Attribution (TDA)
What is Training Data Attribution (TDA)?
TDA connects a model’s decisions to its training data. This not only helps explain the model but also aids in:
- Model Debugging
- Data Summarization
- Machine Unlearning
- Dataset Selection
- Fact Tracing
The Need for Better TDA Evaluation
Research in TDA is growing, but evaluating its effectiveness remains a challenge. Existing metrics lack a systematic approach, which is essential for gaining trust within the research community.
Introducing Quanda
The Fraunhofer Institute for Telecommunications has developed Quanda, a Python toolkit designed to fill this gap. Quanda offers:
- A comprehensive set of evaluation metrics
- A unified interface for easy integration with TDA implementations
- User-friendly and thoroughly tested features
Key Features of Quanda
Quanda integrates with popular libraries like PyTorch Lightning and HuggingFace Datasets, allowing users to avoid reimplementing existing features. It provides:
- A standard interface for various methods
- Multiple metrics for thorough assessment
- Precomputed benchmarks for reproducibility and reliability
How Quanda Stands Out
Unlike other tools such as Captum and Alibi Explain, Quanda offers:
- Extensive and comparable evaluation metrics
- Modular interfaces for flexibility
- Support for novel TDA methods
Components of Quanda
Quanda consists of three main components:
- Explainers: Represent specific TDA methods.
- Metrics: Summarize performance and reliability.
- Benchmarks: Enable standard comparisons.
