This is a new laboratory established in April 2023. We study theory and methodologies of machine learning and dependable artificial intelligence, especially AI security and privacy, explainable AI, and AI fairness. Also, we are working with external universities on AI-based pathological diagnosis of malignant lymphoma, AI-based attacks on automated driving systems and security.
The PI of this lab (Sakuma) is also the PI of the AI Security and Privacy Team, RIKEN Center for Advanced Intelligence Project (AIP).
Research
Please refer to google scholar and DBLP for publication outputs. Recent research interests include:
AI security (attacks on AI, adversarial examples, model poisoning, model inversion), AI privacy (differential privacy, multiparty computation), explainable AI, AI fairness, copyright protection of AI models and AI-generated knowledge, and language model security and privacy.
Real-world application problems working with outside research organizations includes the application of explainable AI to the pathological diagnosis of malignant lymphomas, and attacks on and defense of AI-assisted automated driving systems.
