Active Search for Sparse Signals with Region Sensing
Yifei Ma, Roman Garnett, Jeff Schneider
Autonomous systems can be used to search for sparse signals in a large space; e.g., aerial robots can be deployed to localize threats, detect gas leaks, or respond to distress call…
Statistical properties of damped Lyman-alpha systems from Sloan Digital Sky Survey DR12
Simeon Bird, Roman Garnett, Shirley Ho
We present new estimates for the statistical properties of damped Lyman- absorbers (DLAs). We compute the column density distribution function at , the line density, $\math…
Exact Sampling from Determinantal Point Processes
Philipp Hennig, Roman Garnett
Determinantal point processes (DPPs) are an important concept in random matrix theory and combinatorics. They have also recently attracted interest in the study of numerical method…
Detecting Damped Lyman- Absorbers with Gaussian Processes
Roman Garnett, Shirley Ho, Simeon Bird +1
We develop an automated technique for detecting damped Lyman- absorbers (DLAs) along spectroscopic lines of sight to quasi-stellar objects (QSOs or quasars). The detection of DL…
