In 2012, Kaggle challenged its community to build an algorithm that could grade high-school essays.2012年,Kaggle给当地学校出了个难题,设计一个算法来评判高中作文。The winning algorithms were able to match the grades given by human teachers.获胜的算法给出的分数居然和真正老师给出的分数相符。Last year, we issued an even more difficult challenge.去年,我们出了一道更难的题。Can you take images of the eye and diagnose an eye disease called diabetic retinopathy?你能从拍摄出的眼睛图像中诊断出糖尿病性视网膜病变吗?Again, the winning algorithms were able to match the diagnoses given by human ophthalmologists.再一次,获胜的演算法给出的诊断和眼科医生的诊断相符。Now, given the right data, machines are going to outperform humans at tasks like this.类似于这样的任务,只要给定正确的数据,机器将完全超越人类。A teacher might 10,000 essays over a 40-year career.一位老师在40年的职业生涯中可能审阅一万篇作文。An ophthalmologist might see 50,000 eyes.一名眼科医生大概可以检查5万只眼睛。A machine can millions of essays or see millions of eyes within minutes.但在短短几分钟之内,机器可以审阅百万篇文章或检查数百万只眼睛。We have no chance of competing against machines on frequent, high-volume tasks.对于频繁、大批量的任务,我们无法与机器抗衡。But there are things we can do that machines cant do.但有些事情机器却无能为力。Where machines have made very little progress is in tackling novel situations.机器在解决新情况方面进展甚微。They cant handle things they havent seen many times before.它们还不能处理未曾反复接触的事情。The fundamental limitations of machine learning is that it needs to learn from large volumes of past data.机器学习致命的局限性在于它需要从大量已知的数据中总结经验。Now, humans dont.人类则不然。We have the ability to connect seemingly disparate ths to solve problems weve never seen before.我们有一种能把看似毫不相关的事物联系起来的能力,从而解决从未见过的问题Percy Spencer was a physicist working on radar during World War II,Percy Spencer是一个物理学家,在二战期间从事雷达的研究工作,when he noticed the magnetron was melting his chocolate bar.他注意到磁控管融化了他的巧克力。He was able to connect his understanding of electromagnetic radiation他从对电磁辐射的理解with his knowledge of cooking in order to invent -- any guesses? -- the microwave oven.联想到烹饪,因此发明了——猜猜是什么?微波炉。201612/482337长春打胎需要一共多少钱即学即用英语会话词典D部分:叙述询问理由进入《即学即用英语会话词典文本》下载页面即学即用英语会话词典这部词典着眼日常生活、学习、工作等语言环境,囊括了当今美国最最简洁、最地道的日常口语表达方式。本词典获得2002年全国优秀畅销书奖 /200707/15584长春市阳光咨询电话However, that is simply not enough.但是,这完全不够。And I think what Herbie said-please listen, listen.我在想Herbie的话,请听一听。We have to listen to ourselves, first of all.首先,我们必须聆听我们自己。If I play, for example, holding the stick-where literally I do not let go of the stick youll experience quite a lot of shock coming up through the arm.举个例子,当我拿着鼓棒,事实上我没有松开它,你能通过手臂感受到强烈的震动。And you feel really quite-believe it or not detached from the instrument and from the stick,even though Im actually holding the stick quite tightly.你会确确实实地感受到,信不信由你,与乐器本身以及鼓棒是分离的,然而事实上,我正紧紧的握着鼓棒。By holding it tightly, I feel strangely more detached.紧紧的握着它,奇怪的是我却感受到更多的分离感。If I just simply let go and allow my hand, my arm, to be more of a support system,suddenly I have more dynamic with less effort. Much more.如果我松开一些,让我的手和手臂作为更好的撑,突然,我用相对少的力气得到更多的动力,多得多。And I just feel, at last, one with the stick and one with the drum.最后我感觉到,一个离鼓槌很近,一个离鼓很近。And Im doing far, far less.我做的越来越少。So in the same way that I need time with this instrument,I need time with people in order to interpret them.所以相同的道理,我需要时间与乐器一起,我需要时间和人们在一起才能去了解阐释他们。Not just translate them, but interpret them.不仅仅是从表面上翻译它,而是演绎它。If, for example, I play just a few bars of a piece of musicfor which I think of myself as a technician that is, someone who is basically a percussion player ...例如,我来演奏一点音乐的片段,从我把自己看做是个会这门技术的人的角度来看,后者,人们称之为打击乐演奏者。And so on. If I think of myself as a musician ...等等...如果从我把自己看做一个音乐家的角度。201605/440630英语会话800句 54 /200608/9217长春市那个医院做流产好

Trade liberalization and economic growth is a permanent goal for all of us as WTO Members.

We must vigorously defend the integrity and effectiveness of the multilateral trading system.各位,我们正处于历史时刻。自由贸易和经济发展,是我们作为世贸成员的恒常目标。我知道,世界有些地方视这目标为威胁多于机遇,但我们必须全力推进多哈发展议程的贸易谈判。我们必须奋力确保多边贸易制度保持健全及具成效。This Conference is a golden opportunity for us to demonstrate our collective resolve to improve the lives of peoples throughout the world through progressive trade liberalization.
