Post-Training and Test-Time Scaling of Generative Agent Behavior Models for Interactive Autonomous Driving

Posted by klaurent Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Learning interactive motion behaviors among multiple agents is a core challenge in autonomous driving. While imitation learning models generate realistic trajectories, they often inherit biases from datasets dominated by safe demonstrations, limiting robustness in safety-critical cases. Moreover, most studies rely on open-loop […]

Probing ground-state degeneracies of a strongly interacting Fermi-Hubbard model with superconducting correlations

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | Summary:The Fermi-Hubbard model and its rich phase diagram naturally emerges as a description for a wide range of electronic systems. Recent advances in semiconductor-superconductor hybrid quantum dot arrays have allowed to realize degenerate quantum systems in a controllable way, e.g., allowing to observe robust zero-bias peaks in Kitaev chains, indicative […]

Kinematics of H I and O VI Absorbers: Insights into the Turbulence Driver of the Multiphase Circumgalactic Medium

Posted by klaurent Chicago

Kavli Affiliate: Hsiaowen Chen |Summary:We investigate large-scale gas kinematics in the multiphase circumgalactic medium (CGM) using the observed correlation between line width (Doppler $b$ parameter) and column density ($N$) for H I and O VI absorbers. Leveraging extensive public galaxy survey data at $zlesssim0.1$, we construct a new galaxy sample based on the availability of […]

Super-Eddington Accretion Geometry: a Remarkable Stability of the Hidden Ultraluminous X-Ray Source Cygnus X-3

Posted by klaurent MIT

Kavli Affiliate: Herman Marshall | Summary:We report on the average and orbital phase-resolved polarization of Cyg X-3 in the hard state during the 2023 Imaging X-ray Polarimetry Explorer (IXPE) observational campaign. We find the polarization degree of $ 21.2 pm 0.4 % $ and polarization angle of $ 92.2 pm 0.5^circ $, well compatible with […]

Navigation Around Unknown Space Objects Using Visible-Thermal Image Fusion

Posted by klaurent Chicago

Kavli Affiliate: David W. Miller | Summary:As the popularity of on-orbit operations grows, so does the need for precise navigation around unknown resident space objects (RSOs) such as other spacecraft, orbital debris, and asteroids. The use of Simultaneous Localization and Mapping (SLAM) algorithms is often studied as a method to map out the surface of […]

Tolerance toward foreigners in ants requires chronic exposure for establishment but only sporadic exposure for maintenance

Posted by dbos Rockefeller

Kavli Affiliate: Daniel Kronauer | Authors: Tiphaine P.M. Bailly, Matteo Rossi, Stephany Valdes-Rodriguez, Thomas Schmitt, Erik T. Frank and Daniel Kronauer | Summary: Social insects discriminate between foreigners and members of their own colony via complex olfactory cues. How plastic this discriminatory behavior is, and whether and under what circumstances ants can learn to accept […]
