$boldsymbol{Steiner}$-Hardness: A Query Hardness Measure for Graph-Based ANN Indexes

Kavli Affiliate: Cheng Peng | First 5 Authors: Zeyu Wang, Qitong Wang, Xiaoxing Cheng, Peng Wang, Themis Palpanas | Summary: Graph-based indexes have been widely employed to accelerate approximate similarity search of high-dimensional vectors. However, the performance of graph indexes to answer different queries varies vastly, leading to an unstable quality of service for downstream […]

DESI Peculiar Velocity Survey — Fundamental Plane

Kavli Affiliate: Risa Wechsler | First 5 Authors: Khaled Said, Cullan Howlett, Tamara Davis, John Lucey, Christoph Saulder | Summary: The Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity Survey aims to measure the peculiar velocities of early and late type galaxies within the DESI footprint using both the Fundamental Plane and Tully-Fisher relations. Direct measurements […]
