Anthropic found a hidden space where Claude puzzles over concepts

Anthropic 发现了一个 Claude 琢磨概念的“隐藏空间”

The AI firm Anthropic has got the clearest glimpse yet at what’s really going on inside large language models as they answer questions or carry out tasks. What they found ranges from the mundane to the unnerving. Researchers at the company built a tool called the Jacobian lens (or J-lens) and used it to uncover a hidden area, which they named the J-space, inside its flagship LLM, Claude. The J-space contains words related to the response a model is working on but may not ultimately produce. If Claude were a person (which it is not), you might say these hidden words reveal what’s on its mind before it actually speaks. Read the full story on what they found. —Will Douglas Heaven 人工智能公司 Anthropic 首次清晰地窥见了大型语言模型在回答问题或执行任务时内部究竟发生了什么。他们的发现从平淡无奇到令人不安，应有尽有。该公司研究人员构建了一种名为“雅可比透镜”（Jacobian lens，简称 J-lens）的工具，并利用它揭示了其旗舰大模型 Claude 内部的一个隐藏区域，他们将其命名为“J-空间”（J-space）。J-空间包含与模型正在处理的响应相关、但最终可能不会输出的词汇。如果 Claude 是一个人（当然它不是），你可能会说这些隐藏的词汇揭示了它在开口说话前的心思。阅读关于他们发现的完整报道。——Will Douglas Heaven

Quote of the day

今日金句

“When we’re talking about AI, we love the hype, we get excited about it. The damn thing never actually lands in practice.” —Vijay Janapa Reddi, an engineering professor at Harvard University, tells Wired why he’s skeptical about grand plans for AI. “当我们谈论人工智能时，我们喜欢炒作，我们对此感到兴奋。但该死的东西在实践中却从未真正落地。” ——哈佛大学工程学教授 Vijay Janapa Reddi 告诉《连线》，他为何对 AI 的宏伟计划持怀疑态度。

One More Thing: Why we should thank pigeons for our AI breakthroughs

额外内容：为什么我们应该感谢鸽子带来的 AI 突破

In 1943, psychologist B.F. Skinner led a secret government project to make bombs more precise. His idea: teach pigeons to guide missiles by pecking at targets on a screen inside a warhead. To train them, Skinner rewarded the birds with food when they made the right decisions, using trial and error to shape their behavior. Unsurprisingly, the military never deployed Skinner’s kamikaze pigeons. Yet his experiments convinced him that pigeons were “an extremely reliable instrument” for studying learning. Decades later, those same principles would help power reinforcement learning, the technology behind some of today’s most advanced AI systems. Discover how pigeons inspired one of AI’s most powerful techniques. —Ben Crair 1943 年，心理学家 B.F. 斯金纳领导了一项政府秘密项目，旨在提高炸弹的精确度。他的想法是：训练鸽子通过啄食弹头内屏幕上的目标来引导导弹。为了训练它们，斯金纳在鸽子做出正确决定时给予食物奖励，利用试错法来塑造它们的行为。不出所料，军方从未部署过斯金纳的“神风特攻队鸽子”。然而，他的实验使他确信，鸽子是研究学习的“极其可靠的工具”。几十年后，这些原则帮助推动了强化学习的发展，这是当今一些最先进 AI 系统背后的技术。探索鸽子如何启发了 AI 最强大的技术之一。——Ben Crair
