Learning transferable representations for dynamic text-attributed graphs (DyTAGs) requires models to capture underlying interaction dynamics that persist across domains. However, existing methods tend to overfit to domain-specific structur…

We propose sliced Orlicz-Wasserstein (SOW) distance which is a generalization of sliced Wasserstein (SW) distance. SOW replaces the $L^p$ norm in SW with a Luxemburg norm cost induced by an Orlicz function $φ$. First, we prove that SOW dis…

Multimodal contrastive learning is a dominant paradigm for learning transferable representations from unlabeled data, but standard objectives primarily capture information that is redundant between modalities. Partial Information Decomposi…

Nathan Lambert 认为，工作文化适配前沿模型与员工交互方式的企业，将相对竞争对手获得巨大加速，员工使用这些模型的灵活度同样关键。他引用 @signulll 的观点：若给 Opus 5.5 完整接入公司邮件、Slack、文档、浏览器、数据库、日历、内部工具、权限与组织记忆，并配合可靠的计算机使用与验证循环，几乎所有白领工作已可无需人类完成。

Accurate assessment of Schistosoma japonicum-associated liver fibrosis is essential for disease management and long-term follow-up in endemic regions. Ultrasound provides non-invasive imaging, but complex local echogenic patterns and anato…

Recommender systems rely heavily on heterogeneous behavioral feedback to infer user preference. Although abundant, these signals are imperfect measurements: the same observed behavior can arise from different underlying states, such as gen…

Predicting smooth dynamics and collisions requires modeling continuous evolution and abrupt state changes. We introduce HamiFormer, a dual-expert diffusion field combining whole-window denoising with residual-corrected Hamiltonian propagat…

Ultrasound (US) acquisition depends on the operator's ability to interpret anatomy and anticipate how the view will change with probe motion. Many robotic US navigation methods select actions without explicitly predicting these anatomical …

Radiomap blind prediction aims to infer radiomaps from observable representations of the propagation environment and base station configuration without field measurements. In practice, the observable representations are inherently incomple…

Runway 即将登陆 Muse。

As AI agents are becoming widely adopted in the financial services industry, careful measurement is essential to understand where they can be reliably deployed and where oversight and professional review remain necessary. Such measurement,…

A trained neural network can be represented by a parameter vector in high dimensions. Learning distributions over these vectors enables the generation of new models across various tasks and architectures. A central challenge is permutation…

Over-the-air computation has emerged as a scalable and efficient solution for deploying federated learning algorithms in wireless networks by exploiting waveform superposition for simultaneous model aggregation. Most existing work struggle…

Unified multimodal models combine understanding, generation, and editing within a single network, offering a promising foundation for versatile multimodal applications. However, growing multimodal contexts make KV cache storage and access …

safe-not-safe 工具可通过 `npx safe-not-safe check migration.sql` 命令检查 Postgres 迁移是否安全。它基于 libpg_query 17 的 WASM 解析器，在浏览器 worker 中下载并编译，支持 PostgreSQL 16，且无遥测。

Flow critics learn return distributions by transporting Gaussian noise to Bellman endpoints via continuous velocity fields. While velocity bootstrapping stabilizes training by querying a successor teacher, existing methods face a structura…

Several works have explored multi-agent reinforcement learning (MARL) in LLM collaboration. However, constructing reliable rewards is difficult in practice, as complete and accurate metrics are often unavailable and hard to aggregate. Pref…

A four-stage LLM pipeline gives up as much as 40.5 accuracy points at its own interfaces (gemma-3-12B on MATH-500, Holm-corrected p = 1.66e-19; the largest tax in the primary family). We hold model, problem, stages, stage prompts and compl…

Model merging efficiently combines specialized large language models (LLMs) without joint retraining, but can substantially alter expert routing in Mixture-of-Experts (MoE) models. Such \emph{routing drift} is often interpreted as routing …

This paper studies learning of shuffle ideals with membership queries as well as with contrastive queries---a form of membership query that reveals not only whether a selected word $w$ is in the target language or not, but also provides a …

Raising the update-to-data (UTD) ratio breaks off-policy critics in two ways grouped as "plasticity loss": collapsing representations and growing value magnitude $|Q|$. We separate them in Soft Actor-Critic (SAC) with scaled critics (width…

Fine-tuning a language model on new data can make it forget facts that it should keep. We ask whether measurements taken at the start of a fine-tuning run can bound, for each protected fact, the probability that the run makes the model for…

Clinical Large Language Models (LLMs) achieve strong medical-exam accuracy; however, a correct answer does not guarantee that the explanation names the concepts that actually drove the decision. We introduce three lightweight, directly int…

IPO 时的市值： NVIDIA：3.45 亿美元 Amazon：4.3 亿美元 Apple：12 亿美元 然而今天，如果一家 neolab 种子轮融资不到 4 亿美元，人们就会质疑它为什么融得这么少。 在我看来，充裕的资本对 AI 初创公司创始人来说是一把双刃剑。

Exponential View 创始人 Azeem Azhar 在拉斯维加斯向约 160 位 IT 副总裁提问，三分之二表示能指出可衡量的 AI 成果，但被追问成果是否好到值得打断 CEO 暑假时，只剩约 8 人。Azhar 认为企业进展缓慢，AI 投入能否回本仍"微妙平衡"；BCG 调查显示约 70% 的 CEO 因 AI 成败关乎自身评价而有动力美化现状。

大约就在一年前，我发布了最早一批关于用 Claude Code 制作视频的帖子之一。 这些视频每一个实际上都花了很长时间用 Claude 反复迭代、调整到位，指出哪里不对等等。 变化之大，令人惊叹。 [引用 @trq212]：把 Claude Code 当作你的视频编辑器 信不信由你，下面你看到的每一个视频都是用 Claude Code 氛围编程做出来的。 🧵 以下是你也能做到的方法：

Arena 宣布 Claude Opus 5.5 (High) 以 1509 分首次登顶 Text Arena，比 Opus 5 (High) 高 18 分（现列第 11）。Opus 4.6 (High) 以 4 分之差保持第 2，Anthropic 包揽该榜前六名；Opus 5.5 (High) 按每百万 token 输入/输出定价折算的混合价格为 $16/MToken，进入 Text Arena 的 Pareto 前沿。

一项覆盖3132名参与者、共五个实验的研究发现，仅当AI建议可用时，人们放弃回答的比例从36-44%骤降至3-6%。由于所用模型Step 3.5 Flash对所测试的电影视觉细节问题几乎全错，参与者正确率反而从27.5%降至9.2%；财务激励能减少求助AI并略提升弃答比例，但未能扭转效应，即使AI答案自动展示时弃答率也降至1-7%。
