AI Signals and Reality Checks AI 溯源 UI:可信交互设计 AI 信号与现实校验(2026 年 2 月 19 日) 今日信号 “它为什么这么做?”正在变成一等产品表面——而不是一个支持工单。 当 AI 系统从“回答问题”升级为执行动作(预约、路由、编辑、审批、发送)时,很多团队正在悄悄形成一种新的 UI 原语: 决策溯源(decision provenance): 用简洁、结构化的方式,展示系统用了什么、做了什么决定。 这不是长篇解释。 也不是带情绪的“故事”。 它更像是一张可读的“回执(receipt)”。 在实践中,做得最好的产品,通常会收敛到一组用户真正关心的溯源字段: * **输入(Inputs):**查阅了哪些数据源(邮件线程、日历事件、CRM 记录、文档段落)

Deep Research 算法交易中的深度学习与强化学习(2018–2025):哪些有效、哪些会失效,以及如何更稳健地落地 2018–2025 年,深度学习(DL)和深度强化学习(DRL)在量化交易里的位置发生了变化:从“论文里很强”逐步走向“可以进入生产体系的工具箱”。但真正被反复验证的,不是“神奇的 Alpha”,而是一些更朴素、也更残酷的结论: * 预测不等于交易:方向准确率提升,并不必然转化为扣除成本后的净收益。 * 风险调整目标更可迁移:Sharpe、回撤等目标往往比“最大化收益”更接近真实约束。 * 泛化才是难点:很多失败来自市场状态切换(regime shift)、数据泄漏、以及过于理想化的回测假设。 下面按模型家族(LSTM/CNN/Transformer)与 DRL 家族(DQN、PPO/A2C/DDPG/SAC)总结关键经验,并给出一个更“可落地”的实践清单。 1)深度学习真正擅长的地方
