    Aanjaneya, Mridul; Gao, Ming; Liu, Haixiang; Batty, Christopher; Sifakis, Eftychios (Association for Computing Machinery, 2017-07-20)
    We present an efficient and scalable octree-inspired fluid simulation framework with the flexibility to leverage adaptivity in any part of the computational domain, even when resolution transitions reach the free surface. ...
  • The Limited Effectiveness of Neural Networks for Simple Question Answering on Knowledge Graphs 

    Mohammed, Salman (University of Waterloo, 2017-12-08)
    Simple factoid question answering (QA) is a task, where the questions can be answered by looking up a single fact in the knowledge base (KB). However, this QA task is difficult, since retrieving a single supporting fact ...
