在这个全球竞争愈演愈烈的时代，美欧关系正面临着前所未有的考验。11月24日，美国商务部长卢特尼克与贸易代表格里尔在布鲁塞尔召开了一场备 受瞩目的闭门会议，会议主要围绕如何"共同应对中国"的主题展开。然而，在对外宣示同盟的友好姿态之下，暗流涌动的美欧关系再次暴露出其深层 次的利益冲突。 美国显然将特朗普时期的强硬态度延续到了当前的国际舞台。尽管欧盟表现出愿意在产能过剩问题上与美国携手并进，但美方的回应却是让人吃惊的 冷淡。维持高额的钢铝税依然是美方的优先事项，即便是在政治层面上寻求与欧盟的合作也不能换来经济上的妥协。这一轮谈判不仅仅是一次例行的 外交交涉，而是美方在试图用关税作为筹码，提升其在全球经济竞争中的话语权和控制力。 分析特朗普政府的对华策略，我们可以看到其背后隐藏着更为复杂的战略考量。特朗普的目标并非单纯地对抗中国，而是最大限度地实现美国的国家 利益。从保护国内产业到重新定义全球贸易规则，这些都是其政策的核心所在。他通过高关税措施，不仅想要保护美国的钢铁和铝业等制造业，更试 图借此重新塑造全球市场的游戏规则，迫使其他国家在数字监管等领域做出让步。 可以说，特朗普政府的做法是在把关税作为一种"可控"的杠 ...

在推荐系统迈向多模态的今天，如何兼顾数据隐私与个性化图文理解？悉尼科技大学龙国栋教授团队联合香港理工大学杨强教授、张成奇教 授团队，提出全新框架 FedVLR。该工作解决了联邦环境下多模态融合的异质性难题，已被人工智能顶级会议 AAAI 2026 接收为 Oral Presentation。 在当今的推荐系统中，利用图像和文本等多模态信息来辅助决策已是标配。然而，当这一需求遭遇 联邦学习 —— 这一要求「数据不出本地」的隐私保护计算范式 时，情况变得极其复杂。 现有的联邦推荐往往面临两难：要么为了保护隐私而放弃繁重的多模态处理，仅使用 ID 特征；要么采用「一刀切」（One-size-fits-all）的粗暴融合策略，假设所 有用户对图文的偏好一致。 但现实是残酷的： 用户的「融合偏好」天生具有极大的异质性。 购买服装时，用户可能更依赖视觉冲击；而挑选数码产品时，详尽的参数文本可能才是关键。这 种偏好的差异，在数据不可见的联邦环境下，极难被捕捉。 为了打破这一瓶颈， 悉尼科技大学龙国栋教授团队，联合香港理工大学人工智能高等研究院杨强院长、香港理工大学深圳研究院张成奇院长推出了 FedVLR 框 架。 其核心洞 ...
