大数据时代英语演讲

Hello, everyone. As we all know, we are now living at the age ofbig data, which leads a revolution that transforms how we think. But many people have half know of big data, they haven’t adopted to the tremendous change. So today I’d like to talk about the three peculiarities of big data. I will be very glad if my speech could help you.

Firstly, all samples rather than sampling analysis. With the development of technology, we are able to process massive data, from which we can get more reliable result than through sampling analysis. So we can give up sampling analysis in most cases. Secondly, efficiency rather than accuracy. At the age of big data, we concern more on efficiency rather than accuracy. In other words, we should allow faults to improve efficiency. Comparing with massive data, some faults do not influence the final result.

Thirdly, correlation is as important as causality. We can’t deny the importance of causality ,but sometimes it is difficult or unnecessary to explore it. For example, the recommendation system of Amazon doesn’t know why the customer who likes Hemingway’s works is likely to buy Fitzgerald’s works, it just recommends and helps Amazon sell more than 100 times books than before Amazon using it. From this example, we can conclude that correlation plays an important role at the age of big data,so please don’t overlook it.

Finally, let’s review the three peculiarities of big data. …………Please remember them, maybe they willhelp you one day.

That’s all, thank you.

Students, guests , teachers and Honorable Judges Good morning ! my great pleasure to share my dream with you today. my dream is to become a teacher.... As the whole world has its boundaries, limits and freedom coexist in our life. I don’t expect complete freedom, which is impossible. I simply have a dream that supports my life. I dream that one day, I could escape from the deep sea of thick schoolbooks and lead my own life. With my favorite fictions, I lie freely on the green grass, smelling the spring, listening to the wind singing, breathing the fresh and cool air and dissolve my soul in nature at last. Simple and short enjoyment can bring me great satisfaction. I dream that one day the adults could throw their prejudice

十篇短篇话题英语演讲

1.Brief introduction of Bon Jovi Bon Jovi is an American band which has been famous for hard rock and heavy mental since 1980. They have 5 initial members, but Alec quitted in 1994. Next year they revealed a new album THESE DAYS, which I think is a turning point in their works’style. After that, their music tends to be mental, soft, something like folk. Their soul lead Jon is an optimistic person, which makes the band a fresh breeze in rock field. No painful anger, no complain, no insincerely cynical view, most of their songs have positive words and energetic tunes. Furthermore, they are also good at balancing the role as stars and the role as artist. They ranked ninth on the selection “the most influential top ten bands on the world” hold by scholars in wall streets and ranked second place on the selection “the best rock bands on the world” given by people around the world. 2.Be responsible to your choice, recognize limitation is not ashamed We all tunnel through space and time with behavior and mind consciously or unconsciously to shape life. We may get a panorama of our whole life in higher dimension, which is fixed by what we did, what we met and what we chose. Life is made up by a series of choices, some we regret, and some we’re proud of. Whatever the results are, we have to take the responsibilities following on the heels of choices, to change, to receive, to celebrate or to bear. Here I want to let you realize that bearing is not a coward’s feature, and no one should be shamed for he can bear or receive what he can’t change. On the contrary, they are brave and calm. They have the courage to live with disappointments even desperate situation. It’s wise to recognize individual’s power is limitation and people shouldn’t be cheated by slogan as “nothing is impossible”. Once you tried, whatever the results turned out to be, you have been an admirable person. 3.What are real harmful animations? At the beginning of April, more than 1000 Japanese animations were banned on internet because the SARFT(广电总局) thinks that there are some extreme scenes for children. Personally, I think that’s ridicule to define animations as something only for young children. Japan has completed systems of different kind animation works for audience. Japanese make it one of their most successful industries. But in China, we have no ranking system from relevant departments, and we regard Japanese animations are sick only because they contain bloody pictures, twisted mentality and radical ideas with a broad criteria. If we look at domestically produced cartoons like happy sheep and gray wolf, you can also find much stupid unreasonable violence which hide behind the crude work and fool plot. Artistic creation should reflect the complex of human. Banning is not a proper way to solve cultural issues. What Chinese cartoon really need are creation, thoughts,

课程论文题目 ——浅谈大数据时代的机遇与挑战 学生:XXX (信息科学技术学院计算机1班) 摘要:随着时代的发展,大数据这个词慢慢进入了人们的视野的当中,而大数据也与我们的生活关联越来越紧密,对我们的影响也越来越大。怎么样才能把握住机遇,在大数据时代中脱颖而出,怎么样才能在大数据时代到来的挑战中稳步前行。 关键词:大数据;机遇与挑战;大数据时代分析 Abstract:with the development of The Times, the word big data slo wly into the people's horizons, and big data is linked to our life more and more closely, to our influence is growing. How to seize the opportunity, in the era of big data, how can ability in the er a of big data move steadily in the coming challenges. Key Words: Big data; Opportunities and challenges; The era of big da ta analysis

一、绪论 (一)什么是大数据? “大数据”作为时下最火热的IT行业的词汇在互联网时代显得越来越重要。大数据究竟有多大?大数据能做些什么?在新互联网时代,这些词汇让我们应接不暇。大数据是指无法在一定时间内用常规软件工具对其内容进行抓取、管理和处理的数据集合。大数据还有四个特性分别是数据量大,种类多,速度快,价值大。大数据技术,是指从各种各样类型的数据中,快速获得有价值信息的能力。最早提出“大数据”时代到来的是全球知名咨询公司麦肯锡,麦肯锡称:“数据,已经渗透到当今每一个行业和业务职能领域,成为重要的生产因素。人们对于海量数据的挖掘和运用,预示着新一波生产率增长和消费者盈余浪潮的到来。”(二)大数据能做些什么? 大数据的应用示例包括了大科学、传感设备网络、天文学、大气学、基因组学、生物学、大社会数据分析、互联网文件处理、制作互联网搜索引擎索引、通信记录明细、军事侦察、社交网络、通勤时间预测、医疗记录、照片图像和图像封存、大规模的电子商务等。仅仅十余年,现在越来越多的政府、企业等组织机构意识到数据正在成为组织最重要的资产,数据分析能力正在成为组织的核心竞争力。大数据不仅是一种海量的数据状态及其相应的数据处理技术,更是一种思维方式,一项重要的基础设施。这或是明天我们治理交通拥堵、雾霾天气、看病难、食品安全等“城市病”的利器,也会为政府打开了解社情民意的更大窗口。众所周知,大数据已经不简简单单是数据大的事实了,而最重要的现实是对大数据进行分析,只有通过分析才能获取很多智能的、深入的、有价值的信息。二、本论 (一)大数据的重要性 1.大数据的处理分析正成为新一代信息技术融合应用的结点 有专家指出,大数据及其分析,会在未来10年改变几乎每一个行业的业务功能,从科学研究到保险,从银行业到互联网,各个不同的领域都在遭遇爆发式增长的数据量。在美国的17个行业中,已经有15个行业大公司拥有大量的数据,其平均拥有的数据量已经远远超过了美国国会图书馆所拥有的数据量。在医疗与健康行业,根据数据预测,如果具备相关的IT设施,数据投资和分析能力等条
