IFDECORATOR: Wrapping Instruction Following Reinforcement Learning with Verifiable Rewards
Reinforcement Learning with Verifiable Rewards (RLVR) improves instruction following capabilities of large language models (LLMs), but suffers from training inefficiency due to inadequate difficulty assessment. Moreover, RLVR is prone to over-optimization, where LLMs exploit verification shortcuts without aligning to the actual intent of user instructions. We introduce Instruction Following Decorator (IFDecorator}, a framework that wraps RLVR training into a robust and sample-efficient pipeline…

If you are a guy who doesn't understand* women you could try to read books by women, listen to songs by women, watch films by women etc. Maybe that is likelier to enlighten you than getting your information from obnoxious men.
* If you think I am claiming to understand women I should clarify that I don't even understand people in general.

I've noticed that @… has a carbon emission number for his blog at the bottom of the pages. So I've decided to try it. With 0.01g (i.e. better than 98% tested pages), it pleased my environmental conscience. I’m not sure how relevant this number is, but it did alleviate some feelings of guilt :)

Oh, why aren't you a cat person? I'll tell you: my brother was attacked, bitten and scratched on both hands this week by a feral cat in his kitchen and had to go for surgery to get the infected parts out. And he did all this to protect his own cat. I'll be watching those 'cute' cat videos with a different kind of feeling. I've heard they taste similar to rabbits.

From Wye-Delta to Cross-Square Recursion Configurations in Graphene-Based Quantum Hall Arrays
In electrical metrology, the quantum Hall effect is accessed at the Landau level filling factor ν = 2 plateau to define and disseminate the unit of electrical resistance (ohm). The robustness of the plateau is only exhibited at this Landau level filling factor and thus places a constraint on the quantized resistances that are accessible when constructing quantized Hall array resistance standards (QHARS) using epitaxial graphene on SiC. To overcome devices constrained by using Hall elements in …

Decoupled Entity Representation Learning for Pinterest Ads Ranking
In this paper, we introduce a novel framework following an upstream-downstream paradigm to construct user and item (Pin) embeddings from diverse data sources, which are essential for Pinterest to deliver personalized Pins and ads effectively. Our upstream models are trained on extensive data sources featuring varied signals, utilizing complex architectures to capture intricate relationships between users and Pins on Pinterest. To ensure scalability of the upstream models, entity embeddings are …

Rigidity aspects of a cosmological singularity theorem
Inspired by the classical singularity theorems in General Relativity, Galloway and Ling have shown the following (cf. Theorem 0): If a globally hyperbolic spacetime satisfying the null energy condition contains a closed, spacelike Cauchy surface $(V,g,K)$ (with metric $g$ and extrinsic curvature ${K}$) which is strictly 2-convex (meaning that the sum of the lowest two eigenvalues of $K$ is positive) then $V$ is either a spherical space or past null geodesically incomplete \cite{Ling, Ling2}. In…

Towards the Datasets Used in Requirements Engineering of Mobile Apps: Preliminary Findings from a Systematic Mapping Study
[Background] Research on requirements engineering (RE) for mobile apps employs datasets formed by app users, developers or vendors. However, little is known about the sources of these datasets in terms of platforms and the RE activities that were researched with the help of the respective datasets. [Aims] The goal of this paper is to investigate the state-of-the-art of the datasets of mobile apps used in existing RE research. [Method] We carried out a systematic mapping study by following the g…

A JWST/MIRI view of k Andromedae b: Refining its mass, age, and physical parameters
Context. kAndb is a substellar companion near the planet-brown dwarf boundary, orbiting a B9IV star at 50-100 au. Estimates of its age and mass vary, fueling a decade-long debate. Atmospheric parameters (Teff 1650-2050 K, log(g) 3.5-5.5) remain poorly constrained due to model differences and heterogeneous datasets. Aims. We refine the characterization of kAndb using mid-infrared data to capture its bolometric emission. Combined with NIR measurements, we constrain Teff, log(g), and radius to red…
