Tianyu Zhang
Biography
Tianyu is a Ph.D. candidate with a primary focus on designing occupant-centric control algorithms for buildings using learning-based approaches. His research is driven by the urgency of addressing the challenges posed by carbon neutrality and the need for energy-saving solutions, even when faced with limited training data.
Within his research area, Tianyu has extensively explored various aspects, including sensor fusion, simulation environment design and implementation, transfer learning, diversity-induced reinforcement learning, multi-agent reinforcement learning, and combinatorial optimization. His expertise spans these domains, allowing him to tackle complex problems from different angles.
Recognized for his outstanding academic performance, Tianyu was awarded the Alberta Graduate Excellent Scholarship during his Ph.D. program. Moreover, his master's thesis was acknowledged as the runner-up for the departmental graduate award in 2020, specifically the outstanding MSc thesis award, with the second position.
