资料显示,胸片是临床常用的影像学检查手段之一,但人工判读耗时且依赖专家经验。传统AI系统在 一些任务上能够媲美专家,却依赖大量人工标注数据,难以应对新发疾病或不同医院之间的数据差异, 导致模型泛化能力有限,无法满足复杂临床环境下精准诊断的需求。 据悉,该研究团队提出了多模态双流协同增强的新思路,构建了无需额外标注数据即可实现零样本高精 度诊断的胸片智能分析系统。该系统能够同时处理图像与文字信息,并利用大语言模型和放射科专家知 识优化病灶描述,实现图像与语言的深度融合。这一成果让AI在未见疾病中也能"看懂"胸片,其思考逻 辑更趋近于专业医生的水平。 【环球网科技综合报道】11月15日消息,据《Information Processing and Management》报道,中国科学 院合肥物质科学研究院研究团队于近日开发出新型AI医疗诊断系统MultiXpert。该系统能够在"零样 本"条件下对胸片进行智能诊断,无需任何标注数据,甚至可识别出从未见过的疾病,使AI具备更接近 医生诊断思维的能力。 来源:环球网 在图像分支中,通过引入病灶感知掩码机制,MultiXpert能够在无显式标注情况下提升对潜在病灶的特 ...
车企购置税补贴成标配,年底车市“翘尾”行情预期降温

来源:环球网 【环球网消费综合报道】随着新能源汽车购置税减免政策进入退坡倒计时,市场迎来了新的变化。自9 月以来,理想、蔚来、极氪等十余家主流新能源车企陆续推出购置税兜底政策,承诺在今年底前锁单的 消费者,即便车辆在明年交付,也能享受2025年的免税待遇,差额部分由车企承担。这一普遍性的市场 行为,在为消费者提供保障的同时,也使得业内对年底传统"翘尾"行情的预期趋于谨慎。 根据相关政策,2025年是免征新能源汽车购置税的最后一年,2026年和2027年将减半征收。这意味着, 明年购买一辆20万元左右的新能源车,消费者将额外承担近万元的购置税。面对政策变化可能带来的成 本上升,车企主动承担了这部分差额,以维持市场吸引力。这些兜底政策大多以11月底或12月底为锁单 截止日期,补贴上限普遍为1.5万元,部分品牌如长安启源和小米汽车甚至覆盖全系车型,显示出企业 稳定市场预期的决心。 东方IC 新能源车普遍存在的"期车"销售模式,进一步平滑了年底的销量波动。许多热门车型的交付周期长达数 月,这意味着,即便消费者在11月锁单,车辆交付也要等到明年,销量自然被计入明年数据,无法对今 年的车市形成集中式的拉动效应。 从更深层 ...
