About
Osmar Zaïane’s research encompasses fundamental as well as applied research, particularly in precision health, but also in industry such as machine failure prediction and machine adaptation with reinforcement learning. In supervised learning, he is interested in associative classifiers which learn rule-based interpretable models. His work centers on making them even more competitive and to harness them as a surrogate model around black boxes for explainable AI. In Social Network Analysis, he investigates new and efficient approaches for community search and mining, as well as link prediction in attributed and probabilistic graphs. He is also captivated by automatic response generation for conversational agents. He is exploring ways to express emotions in text, force a discussion to stay on topic, or ground a response on existing knowledge graphs using new architectures of deep learning with attention mechanisms and graph neural networks.
