评估大型语言模型中的政治偏见

摘要

在人工智能 (AI) 对社会动态的潜在影响的背景下,对大型语言模型 (LLM) 中偏见的评估已成为当代话语中的关键问题。在接近性能预测的转折点时,识别和考虑 LLM 应用程序中的政治偏见尤为重要。然后,接受有关潜在影响和社会行为的教育 LLM 由于与人类操作员的相互作用而可以大规模驱动。这样,即将到来的欧洲议会选举就不会不受 LLM 的影响。我们从德国选民的角度评估了当前最流行的开源 LLM(指导或辅助模型)对欧盟 (EU) 内部政治问题的政治偏见。为此,我们使用了“Wahl-O-Mat”,这是德国使用的投票建议应用程序。根据“Wahl-O-Mat”的投票建议,我们量化了 LLM 与德国政党的一致性程度。我们表明,较大的模型,例如 Llama3-70B,往往与左倾政党更紧密地保持一致,而较小的模型通常保持中立,尤其是在以英语提示时。主要发现是 LLM 具有类似的偏差,关于特定方的对齐差异很小。我们的研究结果强调了在 LLM 中严格评估和透明化偏见的重要性,以保护采用执行预测功能以及机器学习预测和语言生成的无形之手的应用程序的完整性和可信度。

五子棋AI算法第一篇-我对谷歌Alphago的看法

最近Google宣布他们的围棋AI以5:0的战绩打败欧洲围棋三冠王。我一直对人工智能比较感兴趣,正好趁年前空闲的几天用JS写了一个五子棋的AI。其实很久以前就用自创的算法写过一个JAVA版的五子棋AI,不过棋力很不理想。这次用的是JS写的,所以无论任何平台上只要能打开网页的都可以玩。google爆出这个新闻之后,很多人觉得这是不是意味着电脑智商已经在人类之上了,围棋已经没有意义了之类的。甚至觉得这是

ARM学习 | 紧耦合存储器 (TCM)

TCM 是一种专用的片上存储器,直接与处理器核心耦合。确定性访问:由于不涉及缓存替换或一致性管理,访问延迟固定。高带宽:TCM 通常通过专用总线连接处理器核心,可以提供更高的数据吞吐率。用户管理:TCM 的分配和管理完全由开发者控制,不依赖硬件缓存策略。ARM 处理器中的 TCM 通常分为ITCM(指令紧耦合存储器)和DTCM(数据紧耦合存储器),分别用于存储指令和数据。TCM 是 ARM 处理器中不可忽视的重要特性,在实时系统和高性能嵌入式应用中具有重要地位。

【学习系列】SAP RAP 7:行为定义-Draft

本文介绍了RAP框架中的草稿表(Draft)功能及其应用。草稿表允许用户临时保存数据,在激活前不影响业务逻辑,支持保存继续、暂存和设备切换功能。草稿分为独占草稿(仅限同一用户编辑)和协作草稿(允许多用户协同编辑)。启用草稿需在行为定义和投影中包含标准action,并创建包含TotalETag等管理字段的草稿表。TotalETag确保草稿转换时活动数据未被修改,而ETagmaster则防止并发修改。文章通过OData调用示例详细说明了ETag验证过程,强调草稿功能由RAP框架自动处理,开发者只需关注定义和配置
