Ahmad Sajedi
I am Ahmad Sajedi, currently pursuing a Ph.D. at the University of Toronto, where I have the privilege of being advised
by Prof. Konstantinos N. Platanioits and Prof. Yuri A. Lawryshyn. Prior to joining UofT, I received my M.Sc. degree from the
Electrical and Computer Engineering Department at the University of Waterloo, mentored by Prof. En-Hui Yang.
My research primarily focuses on Efficient Learning, Dataset Distillation, Knowledge Distillation, and Visual Multilabel Representations. I am open to collaboration and available to address any inquiries regarding my research. Please
do not hesitate to reach out to me via email.
