ANM-PhaseLift: Structured Line Spectrum Estimation from Quadratic Measurements
Zhe Zhang, Zhi Tian
PhaseLift is a noted convex optimization technique for phase retrieval that can recover a signal exactly from amplitude measurements only, with high probability. Conventional Phase…
Low-complexity optimization for Two-Dimensional Direction-of-arrival Estimation via Decoupled Atomic Norm Minimization
Zhi Tian, Zhe Zhang, Yue Wang
This paper presents an efficient optimization technique for super-resolution two-dimensional (2D) direction of arrival (DOA) estimation by introducing a new formulation of atomic n…
Discovering Job Preemptions in the Open Science Grid
Zhe Zhang, Brian Bockelman, Derek Weitzel +1
The Open Science Grid(OSG) is a world-wide computing system which facilitates distributed computing for scientific research. It can distribute a computationally intensive job to ge…
Increasing Parallelism in the ROOT I/O Subsystem
Guilherme Amadio, Brian Bockelman, Philippe Canal +3
When processing large amounts of data, the rate at which reading and writing can take place is a critical factor. High energy physics data processing relying on ROOT is no exceptio…
Trifo-VIO: Robust and Efficient Stereo Visual Inertial Odometry using Points and Lines
Feng Zheng, Grace Tsai, Zhe Zhang +3
In this paper, we present the Trifo Visual Inertial Odometry (Trifo-VIO), a tightly-coupled filtering-based stereo VIO system using both points and lines. Line features help improv…
PIRT: A Runtime Framework to Enable Energy-Efficient Real-Time Robotic Applications on Heterogeneous Architectures
Liu Liu, Shaoshan Liu, Zhe Zhang +3
Enabling full robotic workloads with diverse behaviors on mobile systems with stringent resource and energy constraints remains a challenge. In recent years, attempts have been mad…
