Stackelberg Coupling of Online Representation Learning and Reinforcement Learning
Integrated, end-to-end learning of representations and policies remains a cornerstone of deep reinforcement learning (RL). However, to address the challenge of learning effective features from a sparse reward signal, recent trends have shifted towards adding complex auxiliary objectives or fully decoupling the two processes, often at the cost of increased design complexity. This work proposes an alternative to both decoupling and naive end-to-end learning, arguing that performance can be signif…

Time Scaling Makes Accelerated Gradient Flow and Proximal Method Faster in Multiobjective Optimization
This paper extends a class of single-objective gradient flows and accelerated proximal methods to the multiobjective optimization domain within Euclidean spaces. The proposed gradient flow is a second-order differential equation composed of a second-order term, a first-order term with asymptotic vanishing behavior, and a gradient term with time scaling. We prove the existence of trajectory solutions to the equation and, through Lyapunov analysis, demonstrate that with appropriate parameter choi…

AutoVeriFix: Automatically Correcting Errors and Enhancing Functional Correctness in LLM-Generated Verilog Code
Large language models (LLMs) have demonstrated impressive capabilities in generating software code for high-level programming languages such as Python and C++. However, their application to hardware description languages, such as Verilog, is challenging due to the scarcity of high-quality training data. Current approaches to Verilog code generation using LLMs often focus on syntactic correctness, resulting in code with functional errors. To address these challenges, we present AutoVeriFix, a no…

Fra i morgen, mandag, skal vi have slebet og lakeret gulvet i hele stueetagen, undtagen entreen, dvs. kŸkken, spiseafdeling og dagligstue (arrangeret i sådan en kantet u-form) plus et værelse ovenpå hvor vi har revet et indbygget skab ned og dermed afdækket gammelt, mŸrklakeret gulv. Det betyder at vi i lŸbet af i dag skal have fjernet alle mŸbler i disse rum og gjort klar til madlavning og spisning i kælderen!
Alt sammen samme uge som YngsteSŸn skal starte på HF Inklusion.

Frequent Extreme Galaxy-scale Outflows among Luminous Early Quasars
The existence of abundant post-starburst/quiescent galaxies just $\sim$1-2 Gyrs after the Big Bang challenges our current paradigm of galaxy evolution. Cosmological simulations suggest that quasar feedback is likely the most promising mechanism responsible for such rapid quenching. Here we report a high detection rate (6/27) of exceptionally fast and powerful galaxy-scale outflows traced by [O III] emission in z $\sim$ 5-6 luminous quasars as revealed by the James Webb Space Telescope (JWST), w…

Yamaguti algebras and noncrossing partitions
Recently, Das defined a new type of algebras, the Yamaguti algebras, which are supposed to serve as envelopes of Lie-Yamaguti algebras appearing naturally in differential geometry. We show that the nonsymmetric operad of Yamaguti algebras admit a simple combinatorial description via noncrossing partitions without singleton blocks.

Feature Space Analysis by Guided Diffusion Model
One of the key issues in Deep Neural Networks (DNNs) is the black-box nature of their internal feature extraction process. Targeting vision-related domains, this paper focuses on analysing the feature space of a DNN by proposing a decoder that can generate images whose features are guaranteed to closely match a user-specified feature. Owing to this guarantee that is missed in past studies, our decoder allows us to evidence which of various attributes in an image are encoded into a feature by th…

Magnetization and magnetostriction measurements of the dipole-octupole quantum spin ice candidate Ce2Hf2O7
We investigate the magnetization and the magnetostriction of the dipole-octupole quantum spin ice candidate Ce2Hf2O7 down to 50 mK. We find that the magnetization curves observed with the magnetic field applied along all the principal axes ([100], [110], and [111]) exhibit a magnetic hysteresis below around 300 mK. In addition, a kink-like feature is observed in the magnetization under B || [111], at which the magnetostriction also shows a convex field dependence. Our classical Monte-…

A long time ago in an LAE far, far away: a signpost of early reionization or a nascent AGN at $z=13$?

A long time ago in an LAE far, far away: a signpost of early reionization or a nascent AGN at $z=13$?
The JADES survey recently reported the discovery of JADES-GS-z13-1-LA at $z = 13$, the highest redshift Ly$α$ emitter (LAE) ever observed. This observation suggests that either the intergalactic medium (IGM) surrounding JADES-GS-z13-1-LA is highly ionized, or the galaxy's intrinsic Ly$α$ emission properties are extreme. We use radiative transfer simulations of reionization that capture the distribution of ionized gas in the $z = 13$ IGM to investigate the implications of JADES-GS-z13-1-LA for…
