—多因素共振,外资4月以来持续流出A股(陆股通北向资金净流入/出)—海外扰动增强中期影响更值得关注●●●●●1)海外经济与主要股市的EPS预期仍有下调压力。IMF近期下调了大部分海外经济体2019年的增长预期,而欧美日的制造业PMI依然趋势向下。美国经济受前期高实际利率压制,2019年基本面下行的压力还会进一步显现,美股EPS预期仍有下修空间。加上风险事件增多,2019年以来全球股市逆基本面的估值抬升行情会明显弱化。

责任编辑:张国帅据台湾媒体报道,日本近日曝出建筑物抗震数据造假的油压机厂家KYB,于本周五(19号)坦陈,将未符合标准的减震及隔震装置唯一外销给了台湾。据《日本经济新闻》报道,KYB子公司Kayaba System Machinery社长广门茂喜坦言,从2003年1月到2018年9月,为了达到日本国家认定标准,公司篡改“Oil Damper”液压减震器的性能数据。

此后,已过巅峰之年的高峰逐渐淡出国家队阵容,最终无缘2002年世界杯。高峰国家队生涯的履历也定格在了32场9粒入球。一直到2003年,已经32岁的老将高峰倒在了“YOYO体测”面前。由于犯规被取消了成绩,他愤然选择退役。曾经叱咤中国足坛的“快刀浪子”,就此隐退江湖。

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).

在整个人工智能领域,人类的感知能力(听、看和理解)被视作人类独有的天赋,但对于AI而言,这是一个巨大挑战。值得一提的是,还有一项巨大的挑战是下围棋,已经被Deepmind开发的AlphaGo,同样使用深度学习方法攻克了。当时震惊了整个世界,也成了“AI革命”的催化剂。

在2018年最后几天,各地税务局纷纷发布关于社保费移交税务部门的通知。福建省税务局和深圳市税务局的通知显示,明年1月1日起,机关事业单位社保费交由税务部门征收。对此,上述人士告诉《中国经营报》记者,主要还是时间紧张,统筹方案来不及出台。“目前各省社保费费率并不统一,全部交由税务部门征管的话,也存在征管难度,所以只能先执行事业单位的社保费征管工作。”
