Chinese scientists have developed a “brain-reading” AI model that could help predict the risk of depression among adolescents up to four years in advance by analyzing how humans respond to facial expressions, a technology expected to inspire future development of embodied intelligent humanoids capable of perceiving human emotion and thoughts through nuanced facial cues.
WHO data show that around 332 million people worldwide have depression, about one-third of whom have treatment-resistant forms of the condition. In China, an estimated 95 million people suffer from depression, National Business Daily reported, citing statistics from the China Mental Health Survey.
Using data from a population-based longitudinal adolescent cohort recruited across several European countries, the research team led by Lu Han, assistant professor at the School of Artificial Intelligence, Shenzhen University, has built an AI model that predicted which 19-year-olds were more likely to develop depression at the age of 23. The predictions were backed up by an independent clinical cohort of individuals with depression. The team’s paper was published in the journal Science Advances this month.
According to Lu, the study used brain scans taken at age 19 to predict depression-related symptoms at age 23. The study focuses on adolescence because the transition from adolescence to early adulthood is a key developmental period when depressive symptoms can increase rapidly. The earlier risks are identified, the greater the opportunity for prevention, Lu told the Global Times on Monday, adding that the findings need to be further validated in middle-aged and older adults and across different ethnic groups in future research.
In this study, the researchers analyzed data from adolescents in the IMAGEN, a population-based longitudinal cohort recruited across several European countries. At age 19, participants underwent an fMRI emotional-face task, and their emotional symptoms were assessed using standardized questionnaires. Genetic data obtained from blood samples were also analyzed, and participants were followed up at age 23. The researchers examined whether neural representations of angry faces at age 19 were associated with emotional symptoms and could predict elevated emotional symptoms four years later.
According to Lu, people without depression can more easily distinguish emotional changes based on others’ facial expressions and respond accordingly – for example, responding with friendliness to a smiling expression. But people with depression cannot do this, and are more likely to assume people are angry with them.
A brain-aligned deep-learning model developed by Lu’s team suggested that those participants whose brains were less able to distinguish between different facial emotions and tended to perceive others as angry were more likely to develop symptoms of depression and anxiety in adulthood.
The hypothesis that adolescents at risk of depression may respond differently to other people’s facial expressions than those without such risk based on the negative information processing bias long observed in depression research: people at risk of depression are more likely to notice, interpret, or remember negative social information, Lu said.
The researchers focused on angry facial expressions because they signal social threat and rejection, which are closely linked to interpersonal difficulties and negativity bias associated with depression. They hope to further understand how this bias develops within the visual system.
Building on this, they created a deep learning model, which mimics how the brain processes visual information, to predict how the brain encodes abstract emotional concepts such as anger.
They found that 19-year-olds whose response to facial expressions was skewed in favour of negative emotions or memories were the most likely to develop some form of depression.
Based on these findings, Lu’s team then developed a marker that can identify possible warning signs.
According to Lu, the study found that the computational biomarker was linked to the depression-related variant rs11123030 and polygenic risk for depression, suggesting that genetic susceptibility may affect emotional perception. It also provided predictive information beyond family stress and socioeconomic factors, complementing rather than replacing environmental risk factors. Therefore, depression is neither purely genetic nor purely psychological, but a complex mental disorder arising from the interplay of genetic susceptibility, brain development, emotional and cognitive processes, and life experiences.
According to Lu, the study is also expected to advance AI by aligning deep neural networks with human brain activity and using parameter perturbations to probe neural mechanisms, allowing models to both predict and explain how biases may arise.
The findings suggest that future affective computing and embodied AI should go beyond simply labeling facial expressions, incorporating visual details while preventing prior assumptions from overriding real-time sensory input, Lu said, adding that the findings could provide valuable insights for developing more interpretable robotic perception systems that more closely emulate the way humans process emotions.
。1月15日,在中国社会产品史上,一定是值得纪念的一天。深圳市永和人工智能科技有限公司前创始人王鑫出狱后,开始了一项新的事业。深圳市永和人工智能科技有限公司推出了主题讨论应用程序“厕所山”;在北京,特雷莫洛为主要熟人推出了多闪社交互动;随后,又推出了一款新的聊天应用程序“聊天宝藏”,这已经很久没有出现过了。罗永浩也出现了。面对威信的主导地位,张一鸣的勇气值得肯定(由一位广受欢迎的多闪产品经理徐鲁然拍摄)。长期以来,中国的社会领域一直不那么活跃。不久前,腾讯集团高级副总裁、伟信集团总裁张小龙改变了2019年在伟信公开赛上在专业舞台上亮相的习惯。

二 | 在“微信之夜”的晚上,他出现了四个多小时,讲述了他对微信、产品和用户的思考。据他透露的数据,2018年8月,微信日登录量超过10亿,这是中国第一个实现这一规模的应用;小程序诞生2周年后,每周活跃用户超过6亿;小游戏月活跃用户超过4亿。从这个角度来看,微信不再是一个简单的社会产品,而是一个平台和生态系统。微信似乎已成为公众批评的对象,根深蒂固。挑战性微信自诞生以来,一直是每个社交产品的命运。

三 | 至少媒体认为,任何与挑战微信无关的社交产品都不是好的社交产品。然而,每一个挑战微信的产品都会在浪潮中消失。最近有子弹短信,1月15日推出的三款产品会是下一个子弹短信吗?我们必须挑战微信吗?在多闪发射时发生了一些有趣的事情。多生的产品经理徐鲁然是90年代后的一代,他对新生小牛的老虎充满恐惧。她的产品团队开发了产品。”我们的团队很年轻,这个产品是针对年轻人的。她还提到了过去的微信开放课程pro,这自然就是微信。她坦诚地说,“多闪解决了微信的一些痛点”:朋友圈只是一个小小的免费关系,缺乏互动和亲密;发一个面膜包需要仔细寻找,不满足年轻人的需要;图片和文本缺乏温度。”我最大的两个问题是,如果我想创造一个动态,我必须从很多方面考虑它;或者我总是怀念最亲近的人的动态。以前传言的并不是摇晃的信件和飞扬的谈话。

四 | multi flash是一种基于短视频的社交产品,主要关注与熟人的社交网络。”大量用户围绕特雷莫洛的短视频在社交平台上分享、互动和讨论。”特雷莫洛总裁张楠表示,用户的需求还没有完全满足。总之,有两种含义:一种是短视频的社会化程度不足以满足用户的社会需求;另一种是短视频的社会化程度不足以满足用户对视频内容的需求。”再加上社交平台的一些局限性。”张楠说,这是推出多闪抖动器的驱动力,这是一款基于抖动器的私人信息功能的短视频社交产品。徐鲁然和张楠指着魏信,魏信很快就禁止了多闪内部地址。几乎同时,远离深圳的一个厕所MT被禁止使用。微信给出的原因是“与黄河有关”。聊天宝藏也不放过,会议开幕被微信封住了。

五 | 在潮宝会议前夕,产品共享链接被微信封禁止。

六 | 今天头条新闻的首席执行官陈林(音)当场降低了姿态,专注于用微型信封缓解敌对气氛。”DoubleFlash不想与微信竞争。双方的立场和要求各不相同。”陈林说,微信不必这样出现。他的语气有点不满,但他呼吁,“微信应该尽快解锁,让用户尽快参与内部测试体验。

七 | ”双倍增长当然对微信有需求。这是Byte Bousing召开新产品发布会议的第一个应用产品,它显示了应用工厂希望它变得流行的愿望。在多闪提供的四种添加好友的方式中,有两种渠道:微信和QQ。在产品方面,多普勒具有正常社会产品提供的功能。例如,视频拍摄、即时消息、红包、朋友圈、表情包等。”在我看来,multi-flash仍然专注于内容制作。“凤凰新闻客户郝文豪手表”的作者告诉凤凰社。COM认为内容是一个字节跳动的基因;多闪存更像是一个朋友圈的产品,用户在其中生成内容和动态,从而产生交互。”也许很多人认为即时通讯功能是一个tweet,但我认为它只是一个补充。”郝文豪告诉凤凰科技说,如果我们进入社交网络(即使是即时通讯),很难打败微信。项目符号文本消息就是一个很好的例子。微信已经形成了一个非常完整的生态系统,这是一个方面。另一个方面是,很难有一种产品能够转移用户在其微信中沉淀的关系链。”社会产品是实用的交流工具。”天齐阿米巴创业合伙人魏武煌说。

八 | 这使得新的社交产品很难利用微信,除非它们满足用户的功利主义目标,如补贴。”它还取决于产品的大小,比如子弹头短信,用户太少,即使很难提供补贴。虽然公众舆论乐于看到“微信被挑战”等矛盾话题,但包括最新的聊天宝藏、厕所mt等在内的多闪暂时无法撼动微信的地位。如果你是一个社区,有自己的游戏方式,就会有美好的地方。”郝文豪说,微博、豆瓣、小红树等内容导向的社区都有自己的生活空间。是创新还是商业生态?在2019年微信开放课程结束后,今天的首席执行官陈林曾经问过吴刚一个问题,回答说:“中国的社会部门结束了吗?未来社会部门可能会有哪些发展和创新?打字节从不隐藏社会野心。不幸的是,多胜的“应用工厂”的最新工作并不能很好地回答陈林的问题。视频拍摄已经成为微信、微博、廖天宝等产品的标准功能。红包功能,微信曾经用红包功能窃取了支付宝的部分市场份额,但现在这不是什么新鲜事。也许徐芦兰提到“性格简单”的性格联想面部表情袋是她认为的一个伟大的功能,但作为一个功能。产品经理,她可能还没学过年轻人还在用的QQ。这个功能已经在QQ上上线很长时间了。

九 | 即使在像世界朋友圈这样的短视频社区,微信不仅提前推出小视频,还支持微视觉和yoo视频。凤凰科技询问了一些用户谁也关心多闪存。他们一致认为,多重闪光并不是一个令人兴奋的革命性功能变化,而是一个“改变背心社会化”的产物。最终的结果是用户只能从微信和微信中返回。其中一位用户因为他们的高期望而失望。”别提有挑战性的微信,我现在甚至都不想用它了。

十 | ”她说,即使是原来的聊天记录也与颤音同步。微信已经成为每一个产品的障碍,所以对于双闪电来说,它的作用更像是震颤关系链的引入和沉淀。有一个不能忽略的背景。

十一 | 官方数据显示,截至2019年1月,特雷莫洛的日活跃用户超过2.5亿,月活跃用户超过5亿。

十二 | 这是双闪电的历史性成就,但相比之下,它是双闪电的历史性成就。

十三 | 看,抖动的增长已经放缓了。2018年6月12日,特雷莫洛宣布国内日用户超过1.5亿,月用户超过3亿。在2018年春节期间,紧张的日常生活从不足4000万增加到近7000万。在触顶之际,挖掘颤栗的最大潜能,剥离颤栗的私信功能,推出社会产品,导入和沉淀关系链,强化颤栗的精细运作,是一种有效的途径。Trembler长期从事电子商务业务,帮助内容创建者进行转移和商业化。然而,当红色信封功能出现在多闪中时,它也有助于颤栗系统有能力支付和完成现金链中最重要的部分。这也是字节敲打的一个重要方面。2017年,今天的头条新闻发布了股票信息平台,而byte bouncing已经申请了一些涉及分期付款、支付、金融和其他泛金融业务的商标。2018年上半年,今天的头条新闻发布了贷款产品;12月,今天的头条新闻发布了保险产品。虽然腾讯被视为对手,但字节跳跃也是向腾讯学习的一种方式。除了“前、中、后”的组织结构外,它还学习了如何将如此多的应用程序与庞大的流量串联起来,建立基于平台的公司,并进一步释放流量带来的红利。

十四 | 徐鲁然,一位有很多闪光灯的产品经理,曾经提到张晓龙,他在微信之夜说了一句话。现在回顾过去是很有意思的——“我所观察到的行业中的许多产品经理毕业后都会被自己的公司误导。”因为公司的宗旨是流动。数量需要实现,所以每个人的关键绩效指标都是如何产生流量以及如何实现流量。一旦围绕这个目标,我们的工作的目的不是制造最好的产品,而是使用一切手段来获得流量。

十五 | 今天,三次社会产品大会推出了三个社会产品,张一鸣、罗永浩、王鑫是著名的企业家。面对“打神”的张小龙,他们尝到了“英国三战鲁布”的滋味。但对于多信、聊天宝、厕所山来说,这一次已不再是中原争夺鹿、一分为二的时代,因为微信一直是一个巨大的、统一的社会河流湖泊相识。
