Example: Using data augmentation techniques to balance the representation of different groups in the training data.
- Fairness-aware machine learning: Developing machine learning algorithms that are explicitly designed to be fair.
Example: Using algorithms that optimize for fairness metrics, such as equal opportunity or demographic parity.
Explainable AI (XAI)
Explainable AI aims to make AI systems more transparent and understandable. This is crucial for building trust and accountability. Research in this area focuses on:
- Developing explanation methods: Creating techniques that can explain how AI systems make decisions.
Example: Using techniques like LIME (Local Interpretable Model-agnostic Explanations) to approximate complex models with simpler, interpretable ones.
- Evaluating explanations: Developing metrics and methods for evaluating the quality of explanations.
Example: Assessing whether an explanation is accurate, complete, and understandable to a human user.
- Human-AI interaction: Designing interfaces and tools that allow users to interact with AI systems and understand their reasoning.
Example: Building a dashboard that allows users to explore the factors that influenced an AI system’s decision.
Privacy-Preserving AI
Protecting privacy is essential when using AI systems that process sensitive data. Research in this area focuses on:
- Differential privacy: Developing techniques that allow AI models to be trained on sensitive data without revealing information about individual data points.
Example: Adding noise to data or model parameters to protect privacy.
- Federated learning: Training AI models on decentralized data sources without sharing the raw data.
Example: Training a model on data from multiple hospitals without transferring the data between them.
- Homomorphic encryption: Allowing computations to be performed on encrypted data without decrypting it.
Example: Analyzing encrypted medical records to identify patterns without revealing the underlying patient information.
Robustness and Security
AI systems should be robust to adversarial attacks and secure against malicious actors. Research in this area focuses on:
- Adversarial defense: Developing techniques to protect AI systems from adversarial attacks, such as adversarial examples.
Example: Using adversarial training to make AI models more robust to adversarial examples.
