Protected Attributes Tell Us Who, Behavior Tells Us How: A Comparison of Demographic and Behavioral Oversampling for Fair Student Success Modeling
Jade Maï Cock, Muhammad Bilal, Richard Davis +2
Algorithms deployed in education can shape the learning experience and success of a student. It is therefore important to understand whether and how such algorithms might create in…
PRISM (Polarized Radiation Imaging and Spectroscopy Mission): An Extended White Paper
PRISM Collaboration, Philippe André, Carlo Baccigalupi +140
PRISM (Polarized Radiation Imaging and Spectroscopy Mission) was proposed to ESA in May 2013 as a large-class mission for investigating within the framework of the ESA Cosmic Visio…
Planck-LFI radiometers tuning
Francesco Cuttaia, Aniello Mennella, Luca Stringhetti +33
"This paper is part of the Prelaunch status LFI papers published on JINST: http://www.iop.org/EJ/journal/-page=extra.proc5/jinst" This paper describes the Planck Low Frequency Inst…
Nonstandard regular variation of in-degree and out-degree in the preferential attachment model
Gennady Samorodnitsky, Sidney Resnick, Don Towsley +3
For the directed edge preferential attachment network growth model studied by Bollobas et al. (2003) and Krapivsky and Redner (2001), we prove that the joint distribution of in-deg…
Discrete Extremes
Adrien Hitz, Richard Davis, Gennady Samorodnitsky
Our contribution is to widen the scope of extreme value analysis applied to discrete-valued data. Extreme values of a random variable are commonly modeled using the generalized…
PRISM (Polarized Radiation Imaging and Spectroscopy Mission): A White Paper on the Ultimate Polarimetric Spectro-Imaging of the Microwave and Far-Infrared Sky
PRISM Collaboration, Philippe Andre, Carlo Baccigalupi +101
PRISM (Polarized Radiation Imaging and Spectroscopy Mission) was proposed to ESA in response to the Call for White Papers for the definition of the L2 and L3 Missions in the ESA Sc…
Future Science Prospects for AMI
Keith Grainge, Paul Alexander, Richard Battye +72
The Arcminute Microkelvin Imager (AMI) is a telescope specifically designed for high sensitivity measurements of low-surface-brightness features at cm-wavelength and has unique, im…
Rapid 3D imaging at cellular resolution for digital cytopathology with a multi-camera array scanner (MCAS)
Kanghyun Kim, Amey Chaware, Clare B. Cook +16
Optical microscopy has long been the standard method for diagnosis in cytopathology. Whole slide scanners can image and digitize large sample areas automatically, but are slow, exp…
Extreme value analysis for the sample autocovariance matrices of heavy-tailed multivariate time series
Richard Davis, Johannes Heiny, Thomas Mikosch +1
We provide some asymptotic theory for the largest eigenvalues of a sample covariance matrix of a p-dimensional time series where the dimension p = p_n converges to infinity when th…
Cauchy, normal and correlations versus heavy tails
Hui Xu, Joel Cohen, Richard Davis +1
A surprising result of Pillai and Meng (2016) showed that a transformation of two iid centered normal random vectors, and $(Y_1,\ldot…
Estimating quantile treatments without strict overlap
Marco Avella-Medina, Richard Davis, Gennady Samorodnitsky
We consider the problem of estimating quantile treatment effects without assuming strict overlap , i.e., we do not assume that the propensity score is bounded away from zero. More…
Foreground Analysis Using Cross-Correlations of External Templates on the 7-year WMAP data
Tuhin Ghosh, A. J. Banday, Tess Jaffe +4
WMAP data when combined with ancillary data on free-free, synchrotron and dust allow an improved understanding of the spectrum of emission from each of these components. Here we ex…
The C-Band All-Sky Survey: Instrument design, status, and first-look data
Oliver G. King, Charles Copley, Rod Davies +13
The C-Band All-Sky Survey (C-BASS) aims to produce sensitive, all-sky maps of diffuse Galactic emission at 5 GHz in total intensity and linear polarization. These maps will be used…
Using Large Multimodal Models to Extract Knowledge Components for Knowledge Tracing from Multimedia Question Information
Hyeongdon Moon, Richard Davis, Seyed Parsa Neshaei +1
Knowledge tracing models have enabled a range of intelligent tutoring systems to provide feedback to students. However, existing methods for knowledge tracing in learning sciences…
A derivation of the free-free emission on the Galactic plane between l=20 and 44 degrees
Marta I. R. Alves, Rodney D. Davies, Clive Dickinson +3
We present the derivation of the free-free emission on the Galactic plane between l=20 and 44 degrees and |b| < 4 degrees, using Radio Recombination Line (RRL) data from the HI Par…
Time Series Estimation of the Dynamic Effects of Disaster-Type Shock
Richard Davis, Serena Ng
This paper provides three results for SVARs under the assumption that the primitive shocks are mutually independent. First, a framework is proposed to accommodate a disaster-type v…
Feature Graph Architectures
Richard Davis, Sanjay Chawla, Philip Leong
In this article we propose feature graph architectures (FGA), which are deep learning systems employing a structured initialisation and training method based on a feature graph whi…
In-flight calibration and verification of the Planck-LFI instrument
Anna Gregorio, Francesco Cuttaia, Aniello Mennella +40
In this paper we discuss the Planck-LFI in-flight calibration campaign. After a brief overview of the ground test campaigns, we describe in detail the calibration and performance v…
