Calgary ML Lab

The Calgary Machine Learning Lab is a research group led by Yani Ioannou within the Schulich School of Engineering at the University of Calgary. The lab has a research focus on improving Deep Neural Network (DNN) training and models, in particular for computer vision applications. Topics of research include: Sparse Neural Network Training, Bias and Robustness of Efficient Deep Learning methods and Domain-Agnostic Self-Supervised Learning.

We collaborate with other research groups within the university with the Artificial Intelligence Research Group, and broader, on applying machine learning and computer vision to novel problems.

news

Jul 24, 2024 Adnan was recently awarded the NSERC Doctoral Fellowship (120,000 CAD for the next three years). The program provides financial support to high-calibre PhD students across Canada.
Jul 2, 2024 Mike Lasby was recently awarded the Faculty of Graduate Studies Doctoral Scholarship which recognizes his research contributions and academic achievements to date. Mike also recently passed his PhD Candidacy examination which puts him one step closer towards graduation!
Apr 1, 2024 CML was awarded 24 RGU (approx. 6 A100-years) of GPU compute in the Digital Research Alliance of Canada Resources for Research Groups (RRG) 2024 competition, to support our research. The RRG program provides access to a large-scale GPU clusters for academic research groups in Canada.
Mar 1, 2024 Muhammad Athar Ganaie was awarded a Mitacs Globalink Graduate Fellowship, to support his MSc research at the University of Calgary. The fellowship will support his research on the development of sparse neural networks for deep reinforcment learning.
Jan 16, 2024 Mike Lasby’s collaborative work with researchers at Google, MIT and the Vector Institute, “Dynamic Sparse Training with Structured Sparsity” (Lasby et al., 2024), was accepted at ICLR 2024! DST methods learn state-of-the-art sparse masks, but accelerating DNNs with unstructured masks is difficult. SRigL learns structured masks, improving real-world CPU/GPU timings!
Dec 6, 2023 Mike Lasby and Adnan Mohammed were awarded highly competitive scholarships in the 2023 Graduate Award Competition: Mike was awarded an Alberta Innovates Graduate Studentship (Technology) in the 2023 Graduate Award Competition. The Government of Alberta funds Alberta Innovates Graduate Studentships (Technology) to support top-quality, research related to Information and Communications Technology (ICT), Nanotechnology, and other technology areas. Adnan was awarded the Alberta Graduate Excellence Scholarship (AGES), recognizing outstanding academic achievement in graduate studies.
