现在回顾,Geoff的团队是如此颠覆计算机视觉研究的:2012年,他的团队构建了一个基于神经网络的系统,在ImageNet 1000个类的物体识别竞赛中将错误率一下降低了40%。在此之前,计算机视觉领域的研究社群已经习惯了每年一小部分的增量提升,而Geoff团队的成绩震惊了整个社群——人们未曾想象过,一个“局外人”会以一种“非传统方法”以如此大的优势赢下竞赛。

2、与阅文充分联动现在的中国有声书和电子书、网文还是分开运营的方式,为了满足碎片化时间下没有时间看书的读者,起点、晋江等文学平台内置了语音朗读功能,与机械的合成声相比,人声朗读更能演绎小说的氛围,或许是时候将语音朗读直接替换为有声书内容了。

3500万美元的亏损相比爱奇艺同期3.169亿美元而言,已经可以收说非常少了。而对于如何盈利,张朝阳表示:“将会进一步减少对视频的大额投入,不花大价钱购买精品剧,转为小投入的自制剧。”对此,互联网评论家丁道师对懂懂笔记表示:“按照搜狐视频现在的亏损缩减趋势和目前其整体的发展策略来看,明年实现盈利是很有可能的,不过还要看搜狐要怎么平衡。其实,不仅仅是搜狐,就是爱奇艺、优酷等头部视频平台想要实现盈利也是比较容易的,只不过作为头部平台的它们想要进一步赚取市场份额和用户规模,所以现阶段它们选择了继续砸钱。而作为二线的搜狐视频,因为在体量和实力方面没有和它们竞争的可能,所以可以先考虑盈利。”

根据协定,新开发银行的初始法定资本为1000亿美元,初始认缴资本为五百亿美元,其中,实缴资本为100亿美元,需分7次以美元支付。截至2018年9月末,实缴资本到位金额为44亿美元。2016年7月18日,新开发银行发行了第一期金额为人民币30亿元(约等于4.48亿美元)的5年期绿色债券。该笔债券亦成为新开发银行资产负债表中唯一的负债。截至2018年9月30日,新开发银行资产总额为103.5亿美元;负债总额为4.5381亿美元。

赵薇“罚酒三杯”:卸任龙薇传媒法人 仍持股95%■本报见习记者陈炜祥源文化被投资者索赔一事还未尘埃落定,8月7日,有最新消息称,西藏龙薇文化传媒有限公司(以下统称“龙薇传媒”)发生法定代表人和高管变更,赵薇已完全退出龙薇传媒经营层面。《证券日报》记者从企查查平台查询信息发现,日前龙薇传媒已更新两条变更信息,变更项目分分别为负责人变更(法定代表人、负责人、首席代表、合伙事务执行人等变更),以及高级管理人员备案(董事、监事、经理等)。

In terms of academic accomplishments, Geoff has more than 250,000 citations, with more than half in the last five years. He has an astoundingly high H-index of 142. He was the co-inventor of the seminal work on Boltzmann Machines and backpropagation using gradient descent (published in 1983 with Terry Sejnowski, and the Nature paper with David Rumelhart in 1986). This work introduced the idea of hidden layers in neural networks, along with a mathematically elegant and computational tractable way to train their affiliated parameters. Hidden layers freed the software from “human control” (such as expert systems) and back propagation allowed non-linear combination to essentially discover prominent features (in a more goal-directed way than humans) in the process. However, it turned out that these ideas were before their time, as there were not enough data or computing power to enable these theoretical approaches to solve real-world problems or beat other approaches in competitions. The early-1980's were dominated by expert systems, which became discredited in by late-1980's when they were proven to be brittle and unscalable. What displaced expert systems was not Geoff's proposals (which were too early), but simplified versions of neural networks which were compromised to work with less data and computation. My Ph.D. thesis (using hidden Markov models) was among them, and these simplified approaches were able to make some contributions with some applications, but like expert systems, they were not able to scale to the hardest problems (such as playing Go, human-level speech or vision).
