@silverfang88 1. 去哪个学校让学生交易合约了？证据拿出来。 2. 哪个法务举报友商了？证据呢？ 3. 哪个币上币收了上币费了？证据？ 币圈就是因为有你这种没证据造谣的傻逼天天喜欢意淫才这么乱。

David Silver在DeepMind负责Reinforcement Learning（RL，强化学习），是AlphaGo团队的核心。他最近有个分享，有些启发： 学习的三个阶段： 1. 基于现有知识的学习 2. 基于人类已有经验的强化学习 3. 忘记人类经验的自我学习 每个更高阶的学习，都在不断丢掉旧的知识，旧的经验。 更具体而言： 1. 当前LLM主流还是Data驱动。问题在于1）Data会成为一个天花板，2）模型会和当前的Data尽量拟合而自身的学习能力被弱化。3）LLM默认会证明自己是对的，所以经常有幻觉的产生。而强化学习是让AI在实际使用中获得数据，反馈，它不试图证明自己是对的，而是不断地在真实世界中试错来验证。 2. 如果没有强化学习，那么AlphaGo只会学会人类的技巧，而没有它第二局超越人类经验的第37手。经验比知识更重要。 3. 而AlphaZero是AlphaGo的下一代，证明了忘记人类经验学习的价值。AlphaZero从完全随机的行为开始，从系统自身生成的经验中学习的方式，使得 AlphaZero 从零开始达到了并超越了人类在围棋和国际象棋等领域的最高水平。 4. 反馈有两种，基于人类经验的反馈（RLHF）和真实世界的反馈。前者是人类事先根据经验设定的标准，但它在真实世界仍然可能是错的。而后者是真正通过行动在真实世界得到的反馈。这是AlphaZero超越AlphaGo的背后原理。 5. David Silver提出“Reward is enough”。我们训练AI的职责主要是把目标和我们的价值观对齐融合在设定的奖励标准中。比如我们设定一个标准，奖励AI让我们变得更健康的策略。这个符合我们的需求，而且这里并不是具体的目标，而是模糊的高层目标——如何变得健康。AI系统自己去优化具体的目标（心率，BMI等），并根据真实的反馈调整具体目标的组合。 6. Anthropic以及一些团队证明了基础模型仍然有提升的空间，因此，Data驱动和强化学习驱动会是两个持续演进的双螺旋，而强化学习会越来越重要。 进一步： 1. 从哲学上讲，在时间之矢方向上的Randomness和熵增是确定的，因而我们无法完全从既有的数据和经验学习，我们只有不停地探索，无论是AI还是我们自身。 2. 我们几乎所有在AI训练中的启示都适用于我们对下一代的教育。 https://t.co/YbjAcqZF4U https://t.co/tG9cFMe0t0 https://t.co/jIR5twS3gj

A Strong Start at #AUE2025#! ⚡️ #ABB# was honored on stage as a Silver Sponsor of the 8th General Conference of the Arab Union of Electricity. 🎖️ We were recognized by Eng. Nasser Al-Qahtani, Deputy Minister of Energy for Electricity Affairs, Eng. Khaled Al-Ghamdi, CEO of Saudi Electricity Company, and Eng. Tarek Hamane, President of the Arab Union of Electricity. Over the past two days, we’ve had the opportunity to engage in insightful discussions and showcase our latest Distribution Solutions, including UniGear Digital Switchgear and SSC600. These innovations are designed to enhance efficiency, reliability, and digital transformation in power distribution. As we enter the final day, we look forward to more valuable conversations and collaborations that will shape the future of energy in the region. Visit us and be part of the discussion! 📍 Hilton Riyadh 🔗 Event details: https://t.co/F0mdInVs0l #AUE2025# #SustainableEnergy# #SmartGrid# #PowerDistribution# #FutureOfEnergy# #Innovation# #DigitalTransformation# #EnergyEfficiency# #ABBMiddleEast# #ABBSaudi#

你不想错过来自 Zapier、CopilotKit、Gradio、Visual Studio Code、Docker、Baserow 等上周的 MCP 更新与公告！ Adam Silverman已将你需要知道的内容总结如下。 （稍后保存） https://t.co/JookRMEkJv

I keep seeing a misconception that transmission lines are made out of copper. For the vast majority of lines (especially overhead), that's not the case. Most power lines are made from a steel core wrapped with aluminum conductors. (that's why power lines look silvery and not coppery) Steel provides the strength, and aluminum provides the conductivity. (they both provide some of each but that's primarily how it works) But isn't copper more conductive than aluminum? For the same cross sectional area, aluminum is only about 60% as conductive as copper, but it's also only 30% as dense as copper. For the same mass of metal, aluminum is about twice as conductive as copper. Copper is better when you're space constrained (like in an electric motor), but aluminum is better when you're weight constrained. Aluminum isn't just a cost saving measure (although it does cost 1/4th as much per kg). For a lot of applications, aluminum is actually better than copper.
