    MIT 医疗数据库 PhysioNet 如何发展为全球数据共享标准

    MIT 与医疗机构合作建立的 PhysioNet,从心电图数据集发展为覆盖电子健康记录、影像、软件和 AI 模型的临床数据平台。去年有超过 15,000 篇科学论文引用 PhysioNet,注册用户来自 180 多个国家;医疗机器学习与 AI 研究者如今已成为其主要用户群体。平台还计划试点允许用户标注数据并贡献专业知识的新系统。

    lar platforms like Health Data Nexus as examples of PhysioNet’s legacy. Although there are now more resources out there hosting similar electronic health data, according to Google DeepMind researcher Vivek Natarajan, both PhysioNet and MIMIC “set the standard,” he says, “and it’s still the standard right now.” That standard, according to those who use the platform, changed how research is conducted. Access to data should not be the determinant for which ideas are possible, according to Ziad Ober

    Kimi K3 与开源权重的升级:Nathan Lambert 谈中美模型差距与开源策略

    Moonshot AI 于 7 月 16 日发布旗舰模型 Kimi K3,这是一个 2.8T 参数的 MoE 模型,权重将于 7 月 27 日开放。作者 Nathan Lambert 认为 K3 是迄今最强的开源模型,在 Vals AI 指数上排名第 2、Artificial Analysis 智能指数第 3、Frontend Code Arena 第 1,开源与闭源、美国与中国模型之间的性能差距已从争议中的 6-9 个月缩短到约 3-5 个月。文章还讨论了开源权重模型对前沿实验室资本开支的减速作用、中国实验室的资本效率,以及美国可能限制中国开源模型的监管动向。

    Anthropic 的 Ted Moskovitz 谈如何将算力转化为智能

    Anthropic Science of Scaling 团队负责人 Ted Moskovitz 表示,团队通过严谨实验减少大型训练前的不确定性,以研究如何把算力转化为更聪明的模型。他认为 AI 加速工作的关键指标是模型改变了多少反事实结果及所需人工干预次数,而更大的模型也可能因使用更少 token 获得同等答案而更具成本效益。他还指出,安全与对齐能够提升产品可用性,并与模型能力发展相互促进。

    t and safety really go hand in hand with capabilities,” he said. Indeed, reinforcement learning from human feedback draws its roots back to a 2017 collaboration between OpenAI and DeepMind: One encouraging trend I put to him is that bigger models are turning out easier to align, not harder. Ted’s own framing was more guarded - it has “gone different from how many safety researchers expected,” he said - but his read is that “people feel pretty good about the alignment situation right now,” temper

    Grant Sanderson 谈 AI 与数学的未来

    Dwarkesh Patel 与 3Blue1Brown 作者 Grant Sanderson 对谈 AI 与数学的未来,讨论 AI 在数学上的进展为何快于其他领域,以及这种进展对其他行业意味着什么。Sanderson 认为 IMO 金牌只是又一个基准,数学内部同样存在参差,几何题可被暴力求解而组合题仍难;他还以 Galois 群论为例说明概念突破的验证回路可能长达百年,并谈到 AI 能否在领域之间建立连接、以及数学家的角色可能转向类似策展人的方向。

    school software that can tell you yes or no, and you use that as your VR. What would corroborate your point is the initial attempts. Again, I’ll circle back to the IMO. Initially, DeepMind basically does that. Everything is in Lean, and then the next year it’s all in natural language. So to your point, it’s not needed. I do think there’s a yet-to-be-explored benefit of that formalization domain, which is that at the moment you still need a human reviewing that counterexample to the unit distance

    欧洲无法靠租用美国模型实现 AI 主权

    欧洲若持续依赖美国 AI 模型与基础设施,就无法掌控关键系统的访问权和经济投入。文章主张欧洲不必追求全球领先,但应在本土建设足够可靠的模型与算力,并让政府充当早期客户,以获得遭遇断供时的替代能力和谈判筹码。

    e window to be a builder rather than a buyer is measured in the time it takes to stand up a cluster, not a career. This should sting, because Europeans invented much of modern AI. DeepMind was founded in London and sold to Google in 2014, and a great deal of the talent that followed now lives in California. Today Europe faces a company worth almost $1tn and American tech giants spending an estimated $450bn a year on AI infrastructure. Its answer has been the EU AI Act and a capital commitment th

    持续学习与后单体 AI 时代:通用性越强,记忆成本越高

    Charlie O’Neill 认为,持续学习的成本会随模型通用性上升,实际部署将走向大量可持续更新的专业模型,而非单一全能模型。文章将现有方案归为稀疏更新与时间尺度分离两类,指出二者都通过限制干扰缓解灾难性遗忘。作者还比较了 SFT 与 RL,认为 RL 的在策略学习和逆 KL 目标更有利于保留既有能力。

    plus a simple heuristic (update what’s specific, leave what’s general) that sidesteps the need to learn how to learn. There was a lot of hype around the (very lengthy) paper from DeepMind on nested learning, which starts with the observation that architecture and optimization aren’t separate things. Rather, they’re the same concept operating at different timescales. A transformer’s attention mechanism is associative memory updating every forward pass. The feedforward layers are associative memo

    Amazon AI 复苏:AWS 与 Anthropic 扩建多吉瓦级 Trainium 基础设施

    AWS 正为 Anthropic 扩建多吉瓦级 AI 训练基础设施,三个接近完工的园区合计拥有逾 1.3GW IT 容量,最大园区将部署近百万颗 Trainium2。Trainium2 的多项性能落后于 NVIDIA 系统,但在单位内存带宽总拥有成本上具有优势,契合 Anthropic 侧重强化学习和训练后扩展的路线。Anthropic 还深度参与 Trainium 的系统设计,同时继续使用 Google TPU 和 NVIDIA GPU。

    e on the Trainium roadmap only grows from here. Put plainly: Trainium2 is converging toward an Anthropic custom-silicon program. This will enable Anthropic to be, alongside Google DeepMind, the only AI labs benefiting from tight hardware–software co-design in the near horizon. This report will dig into all aspects of Amazon’s AI resurgence: the Anthropic partnership, datacenters, and Trainium. At the end of the report, we provide a longer-term outlook on Anthropic, AWS Bedrock and internal model

    METR:AI 模型在公开部署前就可能带来危险

    METR 发文指出,当前前沿实验室的安全政策多聚焦部署前测试,但模型在公开部署前就可能带来风险,包括模型权重被窃取滥用、实验室员工内部滥用,以及 AI 智能体在训练或内部使用中自主追求非预期目标。文章建议把重心转向更早的能力测试与预测、模型权重安全与内部监控、以及透明披露和举报人保护等政策。
