你收到的每一条AI回复，最初都始于一个电子⚡
黄仁勋近期接受红杉资本采访时将AI基础设施比作五层蛋糕：在芯片、数据中心、模型之下的最底层是能源。智能时代的核心约束并非算力、软件，而是电力。英伟达将AI工厂称作当代发电机，输入电子、输出智能token，这场人类史上最大规模基建已投数千亿美元，仍需数万亿跟进，核心问题是电网能否跟上AI扩容节奏⬆️

arXiv feed 可能略旧，保留论文链接SM4RT: Learning Structured Motion Geometry for 4D Reconstruction
Geometry Foundation Models (GFMs) have substantially advanced monocular 3D reconstruction, yet extending this capability to 4D dynamic understanding remains a fundamental challenge.
Skill Self-Play: Pushing the Frontier of LLM Capability with Co-Evolving Skills
LLM training is shifting from manual design and annotation to interaction-driven self-evolution.
Explainable Reinforcement Learning for assisting Air Traffic Controllers
To effectively integrate AI into high-stakes, critical environments such as healthcare, autonomous driving, and aviation--and to advance toward higher levels of automation and seamless human-AI collaboration--building trust in AI-driven solutions is essential.
The Regression Tax: Decomposing Why Skills Help and Hurt LLM Agents
Adding procedural skills to an LLM agent is typically evaluated by average improvement in task success.
PinEqualizer: Full Funnel Content Exploration and Debiasing System at Pinterest
In this paper, we propose a new solution for addressing the content cold-start problem in industry-scale search and recommender systems.
Quantum Spectral Model: Data Reuploading with Input-Conditioned Frequency Suppor...
A central design principle in modern machine learning and artificial intelligence is to align a model's inductive bias with the structure of its input data.
