Enabling Pareto-Stationarity Exploration in Multi-Objective Reinforcement Learning: A Multi-Objective Weighted-Chebyshev Actor-Critic Approach

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Fnu Hairi, Fnu Hairi, , , | Summary: In many multi-objective reinforcement learning (MORL) applications, being able to systematically explore the Pareto-stationary solutions under multiple non-convex reward objectives with theoretical finite-time sample complexity guarantee is an important and yet under-explored problem. This motivates us to take the […]

Excitation and tunneling spectra of a fractional quantum Hall system in the thin cylinder limit

Posted by klaurent Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Jyesta M. Adhidewata, Jyesta M. Adhidewata, , , | Summary: The excitations of fractional quantum Hall effect (FQHE) states have been largely inaccessible to experimental probes until recently. New electron scanning tunneling microscopy (STM) results from Hu et.al. (2023) show promise in detecting and identifying these […]

Heterogeneous Ensemble Enables a Universal Uncertainty Metric for Atomistic Foundation Models

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Kai Liu, Kai Liu, , , | Summary: Universal machine learning interatomic potentials (uMLIPs) are reshaping atomistic simulation as foundation models, delivering near textitab initio accuracy at a fraction of the cost. Yet the lack of reliable, general uncertainty quantification limits their safe, wide-scale use. Here we […]

Information in 4D-STEM: Where it is, and How to Use it

Posted by klaurent Cornell

Kavli Affiliate: David A. Muller | First 5 Authors: Desheng Ma, Desheng Ma, , , | Summary: Contrast transfer mechanisms for electron scattering have been extensively studied in transmission electron microscopy. Here we revisit H. Rose’s generalized contrast formalism from scattering theory to understand where information is encoded in four-dimensional scanning transmission electron microscopy (4D-STEM) […]

AnimeColor: Reference-based Animation Colorization with Diffusion Transformers

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Yuhong Zhang, Yuhong Zhang, , , | Summary: Animation colorization plays a vital role in animation production, yet existing methods struggle to achieve color accuracy and temporal consistency. To address these challenges, we propose textbfAnimeColor, a novel reference-based animation colorization framework leveraging Diffusion Transformers (DiT). Our approach […]

X-Raying a Be star disk: fundamental parameters of the eclipsing binary Be star V658 Car

Posted by klaurent MIT

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Tajan H. de Amorim, Tajan H. de Amorim, , , | Summary: With its two stellar eclipses and two disk attenuations per binary orbit, V658 Carinae stands out as the first clear eclipsing Be + sdOB system. This rare alignment offers a unique opportunity to probe […]

The First Day of a Type Ia Supernova from a Double-Degenerate Binary

Posted by klaurent UCSB

Kavli Affiliate: Lars Bildsten | First 5 Authors: Gabriel Kumar, Gabriel Kumar, , , | Summary: Supernovae in binary star systems involve a hydrodynamical interaction between the ejecta and a binary companion. This collision results in shock heating and a modified density structure for the ejecta, both of which affect the light curve. As highlighted […]
