Causality-Informed Data-Driven Predictive Control

Kavli Affiliate: Biao Huang | First 5 Authors: Malika Sader, Yibo Wang, Dexian Huang, Chao Shang, Biao Huang | Summary: As a useful and efficient alternative to generic model-based control scheme, data-driven predictive control is subject to bias-variance trade-off and is known to not perform desirably in face of uncertainty. Through the connection between direct […]

Scaling User Modeling: Large-scale Online User Representations for Ads Personalization in Meta

Kavli Affiliate: Yi Zhou | First 5 Authors: Wei Zhang, Dai Li, Chen Liang, Fang Zhou, Zhongke Zhang | Summary: Effective user representations are pivotal in personalized advertising. However, stringent constraints on training throughput, serving latency, and memory, often limit the complexity and input feature set of online ads ranking models. This challenge is magnified […]

GRB 180128A: A Second Magnetar Giant Flare Candidate from the Sculptor Galaxy

Kavli Affiliate: Nicola Omodei | First 5 Authors: Aaron C. Trigg, Eric Burns, Oliver J. Roberts, Michela Negro, Dmitry S. Svinkin | Summary: Magnetars are slowly rotating neutron stars that possess the strongest magnetic fields ($10^{14}-10^{15} mathrm{G}$) known in the cosmos. They display a range of transient high-energy electromagnetic activity. The brightest and most energetic […]

Project Dinos I: A joint lensing-dynamics constraint on the deviation from the power law in the mass profile of massive ellipticals

Kavli Affiliate: Joshua Frieman | First 5 Authors: Chin Yi Tan, Anowar J. Shajib, Simon Birrer, Alessandro Sonnenfeld, Tommaso Treu | Summary: The mass distribution in massive elliptical galaxies encodes their evolutionary history, thus providing an avenue to constrain the baryonic astrophysics in their evolution. The power-law assumption for the radial mass profile in ellipticals […]

BPS Fivebrane Stars II: Fluctuations

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, Yoav Zigdon, , , | Summary: We investigate quantum fluctuations of metric components in coherent 1/2-BPS bound states of $n_1$ fundamental strings and $n_5$ NS5-branes. The leading order contribution in an expansion in $1/(n_1n_5)$ is calculated via a combination of analytical and numerical […]

BPS Fivebrane Stars I: Expectation Values of Observables

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, Yoav Zigdon, , , | Summary: We study ensembles of 1/2-BPS bound states of fundamental strings and NS-fivebranes (NS5-F1 states) in the AdS decoupling limit. We revisit a solution corresponding to an ensemble average of these bound states, and find that the appropriate […]
