But one point I would like to make is that all of these findings on brain algorithms are also going to enable next generation AI because AI right now as much as it is exciting has very severe limitations which is that it uses unbelievable amount of energy for tasks that are relatively easy for human beings. And so us as human beings the human brain is designed to have very good energy efficiency. I believe after like learning a lot about how the brain algorithm works, the brain's main design principle is en ...

Core Insights - The article discusses the paradox of advanced AI models becoming less obedient to instructions despite their enhanced reasoning capabilities [2][4][15]. Group 1: AI Model Performance - The emergence of powerful AI models like Gemini 2.5 Pro, OpenAI o3, and DeepSeek-R1 has led to a consensus that stronger reasoning abilities should improve task execution [2]. - A recent study found that most models, when using Chain-of-Thought (CoT) reasoning, actually experienced a decline in execution accuracy [25][27]. - In the IFEval test, 13 out of 14 models showed decreased accuracy when employing CoT, while all models performed worse in the ComplexBench test [27][28]. Group 2: Experimental Findings - The research team from Harvard, Amazon, and NYU conducted two sets of tests: IFEval for simple tasks and ComplexBench for complex instructions [18][20]. - The results indicated that even large models like LLaMA-3-70B-Instruct dropped from 85.6% accuracy to 77.3% when using CoT, highlighting the significant impact of reasoning on performance [29][30]. - The study introduced the concept of "Constraint Attention," revealing that models using CoT often lose focus on key task constraints, leading to errors [38][39]. Group 3: Recommendations for Improvement - The study proposed four methods to mitigate the decline in accuracy when using reasoning models: Few-Shot examples, Self-Reflection, Self-Selective Reasoning, and Classifier-Selective Reasoning [47][56]. - The most effective method was Classifier-Selective Reasoning, which involves training a small model to determine when to use CoT, resulting in improved accuracy across tests [58].

在今年，DeepSeek R1火了之后。 几乎快形成了一个共识，就是： AI推理能力越强，执行任务时就应该越聪明。 从2022年Chain-of-Thought横空出世，到今天Gemini 2.5 Pro、OpenAI o3、DeepSeek-R1、Qwen3，这些旗 舰模型的统治性表现，我们一直相信，让模型先想一想，是一个几乎不会出错的策略。 不过，这种聪明，也会带来一些副作用。 就是提示词遵循能力，变得越来越差。 换句话说，就是越来越不听你的话了。 我在过年期间写DeepSeek的攻略文： DeepSeek的提示词技巧，就是没有技巧。 的时候，也提到了这一 点。 不过，这只是我自己使用中的感觉，它变的越来越聪明，但是感觉，却越来越不听话了，以至于我现 在，最常用的模型，开始越来越变成了GPT4o，所有的推理模型，反而会用的越来越少了。 不过，确实没有经历过验证，所以也不是特别敢说。 直到昨晚回来，在扒拉论文的时候，看到一篇提到这个话题的论文，我读完以后，我觉得，终于可以来 聊聊这个事了。 这篇论文叫，《When Thinking Fails: The Pitfalls of Reasoning for I ...

人机共生：脑机接口行业专家会议 20250518 Q&A 脑机接口技术的基本概念是什么？它的分类和应用场景有哪些？ 脑机接口技术是将大脑活动与外部设备直接连接，通过捕捉和解码大脑信号， 将人的意图和思维转化为计算机可以识别的指令，实现人和机器之间的交互。 脑机接口分为单向和双向两种类型。单向接口通过读取大脑信号来控制外部设 备，而双向接口则可以对大脑进行信号传输，进行刺激。主要应用场景包括神 经退行性疾病调控、瘫痪患者辅助等。 • 中国脑机接口技术发展紧随美国，但存在 1-2 年差距，主要体现在资金投 入、供应链资源和芯片开发速度上。国内企业如脑虎科技、南微医学等从 低通道产品起步，逐步追赶国际领先水平。 • 脑机接口应用场景广泛，医疗端包括疾病治疗和功能替代，消费端包括大 脑状态监测和人机交互。非侵入式手段在注意力训练、情绪调整和助眠等 领域有望率先实现规模化落地。 • 医保政策的出台旨在支持脑机接口产业发展，但湖北省制定的嵌入式脑机 接口费用指导价可能偏低。监管重点在于安全性和有效性，通过严格临床 试验驱动医疗器械开发，并逐步完善监管条例。 脑机接口技术的发展现状及市场规模如何？ 摘要 • 脑机接口技术商 ...
