"We can get hormone levels, physiological data,disease status."

VOA: standard.2010.02.22

Sometimes you get data that throw you off.

有时候你们得到一些你们认为无用的数据。

Why not? Well, they can't get data, there wasn't a stock market.

为什么呢,因为作者无法得到数据,两国没有股票市场

And we're data junkies, so we like to get a lot of data before we make a big decision like that.

我们是数据控，所以一般先收集很多数据,在做重大决定的时候。

I, somehow if, I want to walk through some sequence of data structures, gathering up or doing the same thing, adding ages in until I get a total age and then divide by the number faculty.

我想，以某种方法，来遍历,一些数据结构，把它们相同的属性加到一起，就是一直的把年龄加到一起一直到,得到了一个年龄总数,然后除以员工的数目。

And one way we can get to that is by looking at two pieces of data.

一种可以得出答案的方法,就是观察2个数据。

A second problem is what I was talking about immediately before this is some of our data are misleading so we get a lot of the information about the world from the media.

刻板印象的另一个问题是,我刚才就讲了,我们接收到的有些信息是误导人的,我们能接收到这个世界很多信息,从媒体上接收到。

Well, there are many factors, but one important factor is, the rise of the Internet has competed with -people used to buy The Wall Street Journal to get data like this.

其实有很多因素,但是最主要一点是,来自网络的竞争,人们过去买《华尔街日报》来获取这些数据

This is useful especially when we get to details like forensics and looking at data on a hard drive, - 'cause if you don't know how much store-- how many bits are composing your file, you're never gonna recover that data or be able to access what you're looking for.

这是很有用的，尤其是在法庭上,查看硬盘驱动器里的数据时，如果你连-,文件有多少比特都不知道，你如何去恢复数据,获取你想要的信息呢。

And we've only just begun using it, but it has just a bunch GetInt GetString GetDouble of very useful functions like GetInt, GetString, GetDouble, And so as those names imply, you can just cull these functions with no arguments and you'll get back that data type based on its name.

我们刚开始使用了它，里面有很多的,有用的函数，像，所以，那些名字暗示，你可以挑选这些,没有参数的函数，然后你可以通过它的名字,获取他们的数据类型。

So we're to assume we can get to any piece of data, any instruction in constant time, and the second assumption we're going to make is that the basic primitive steps take constant time, same amount of time to compute. Again, not completely true, but it's a good model, so arithmetic operations, comparisons, things of that sort, we're all going to assume are basically in that in that particular model.

因此如果我们假设在恒定的时间内,我们可以取得任何一块数据,任何一种数据结构的话,我们要做的第二个假设就是,基本的原始操作计算花费的时间是恒定的,这个假设也不是完全正确的，但这个模型其实挺不错的，因此算法操作，比较，这一类的事情，我们在这个特定的模型中都假设是基本的,操作，花费的时间是恒定相同的。

So what data type can we use to actually get more bits of precision than an int?

所以我们能用什么数据类型来表示,比int类型更多位数的数呢？

In my in my area of research, it's common for us to want to process about 100 images a second in order to get real time display. Each image has about a million elements in it. I 've got to process about a half a gig of data a second in order to get anything out of it.

在我们的研究领域内，我们经常要在一秒钟内处理大概,100张图片以获得实时显示,每个图片大概包括了100万像素,因此我必须在1秒内,处理半个G的数据,来获取我想要的。
