Next month, Mila researchers will showcase their work in full force at the 38th International Conference on Machine Learning (ICML). This annual event brings together some of the brightest minds of the machine learning research community and will run virtually from July 18 to 24.

Of the 5,513 submissions this year, 1,184 papers were accepted (21.5%); 30 of those papers were co-authored by Mila researchers. 

The work being presented by Mila researchers covers a wide range of topics and demonstrates the far-reaching potential applications of machine learning in areas such as health, chemical physics, and even the airline industry. 

In “Structured Convolutional Kernel Networks for Airline Crew Scheduling,” Mila core academic member Simon Lacoste-Julien and colleagues introduce a novel deep structured predictor: structured convolutional kernel networks (Struct-CKN). The initial solutions obtained using Struct-CKN on a flight-connection dataset revealed that it can be further refined by an airline crew scheduling solver. 

Core faculty member Jian Tang and team designed a unified framework, Local-instance and Global-semantic Learning (GraphLoG), for self-supervised whole-graph representation learning, proposing hierarchical prototypes to capture global semantic clusters. The verified experiments on chemical and biological benchmark data sets demonstrate the method’s effectiveness, with potential implications for many tasks such as molecule properties prediction in drug and material discovery. 

On the other end of the spectrum, in “Continuous Coordination As a Realistic Scenario for Lifelong Learning,” Mila University professors Sarath Chandar and Aaron Courville, as well as research intern Hadi Nekoei and Master’s student Akilesh Badrinaaraayanan introduce Lifelong Hanabi, a continual multi-agent reinforcement learning testbed in which every task is coordinating with a partner that’s an expert player of Hanabi.
