- Cooperative AI: Designing AI systems that can collaborate effectively with humans and other AI systems to achieve shared goals. This is crucial for complex tasks like scientific discovery, where AI can augment human capabilities.
- Formal Verification: Using mathematical techniques to formally prove that an AI system satisfies certain safety properties. This is particularly important for safety-critical applications like autonomous aircraft.
2. Robustness
Robustness refers to the ability of an AI system to perform reliably and consistently even in the face of unexpected inputs, adversarial attacks, or changing environments. AI systems can be surprisingly brittle and vulnerable to subtle perturbations in their inputs, which can lead to catastrophic failures. For instance, a self-driving car might misinterpret a stop sign with a small sticker on it, leading to an accident. Research in robustness aims to develop AI systems that are more resilient to these kinds of attacks. Key areas of research include:
- Adversarial Training: Training AI systems to defend against adversarial examples by exposing them to a wide range of perturbed inputs during training.
- Input Validation: Developing methods for detecting and rejecting invalid or malicious inputs before they can affect the AI system's behavior.
- Uncertainty Quantification: Estimating the uncertainty in an AI system's predictions and using this information to make more robust decisions. For example, if an AI system is uncertain about the presence of an object in an image, it might defer to a human operator for confirmation.
- Anomaly Detection: Identifying unusual or unexpected patterns in data that could indicate a problem with the AI system or its environment.
3. Controllability
Controllability refers to the ability of humans to effectively control and manage AI systems, even as they become more complex and autonomous. This is crucial for ensuring that AI systems remain aligned with human values and do not deviate from their intended purpose. Research in controllability explores various approaches, including:
- Interruptibility: Designing AI systems that can be safely interrupted or shut down by humans in case of emergencies.
- Explainable AI (XAI): Developing AI systems that can explain their reasoning processes to humans, allowing humans to understand and correct their behavior.
- Human-in-the-Loop Systems: Designing AI systems that work in collaboration with humans, allowing humans to oversee and guide their actions.
