Scalable subgraph representation learning through simplification
(2023-06-01)
Link prediction on graphs is a fundamental problem. Subgraph representation learning approaches (SGRLs), by transforming link prediction to graph classification on the subgraphs around the links, have achieved state-of-the-art ...
Investigating proteomic profiles of rainbow trout (oncorhynchus mykiss) kidney and liver tissues exposed to low concentrations of waterborne nickel
(2023-08-01)
Nickel has become a component of natural freshwater that may pose serious ecological risks to aquatic wildlife. Due to Canada’s significant presence in producing and exporting nickel, the country has the opportunity to ...
Preferential proximal policy optimization in reinforcement learning
(2023-12-01)
The Proximal Policy Optimization (PPO), a policy gradient method, excels in reinforcement learning with its ”surrogate” objective function and stochastic gradient ascent. However, PPO does not fully consider the significance ...
Preliminary design of a social asymmetric virtual reality upper-limb exergame for individuals with dementia utilizing insights from caregivers
(2023-10-01)
This thesis investigates the usability, task load, cooperative performance, and social presence effects of an asymmetric VR game for upper limb activity in the context of elderly care from the perspective of caregivers. ...
