Fast computation of clustered many-to-many shortest paths and its application to map matching
Published 2020“…We examine the problem of computing shortest paths in a transportation network from a set of geographically clustered source nodes to a set of target nodes. Such many-to-many shortest path computations are an essential and computationally expensive part of many emerging applications that involve map matching of imprecise trajectories. …”

The hierarchy of Davydov’s Ansätze: from guesswork to numerically “exact” many-body wave functions
Published 2023“…The multiple Davydov Ansätze have been proposed, with the increasing Ansatz multiplicity, as incremental improvements of their single-Ansatz parents. For a given Hamiltonian, the time-dependent variational formalism is utilized to extract accurate dynamic and spectroscopic properties using Davydov’s Ansätze as its trial states. …”

A high-performance main-memory query engine on emerging many-core processors
Published 2018“…Firstly, we revisit the state-of-the-art hash join algorithms and software optimizations experimentally on the many-core processor with die-stacked HBMs. We find that although many findings on database algorithms from existing studies are still valid on the latest many-core architecture, there are major performance issues that existing optimizations are insufficient to address. …”

Tilted biorthogonal ensembles, Grothendieck random partitions, and determinantal tests
Published 2024“…These deformations of Schur polynomials introduced in the K-theory of Grassmannians share many common properties. Our Grothendieck measures are analogs of the Schur measures on partitions introduced by Okounkov (Sel Math 7(1):57–81, 2001). …”

Application of variational graph encoders as an effective generalist algorithm in computer-aided drug design
Published 2023“…Although there has been considerable progress in molecular property prediction in computer-aided drug design, there is a critical need to have fast and accurate models. Many of the currently available methods are mostly specialize in predicting specific properties, leading to the use of many models side-by-side that lead to impossibly high computational overheads for the common researcher. …”
