阅读笔记-Lesson10

我的答案：

而且每年都有更多的资金投入到新的投资项目中。AngelList, U。这家总部位于美国的平台连接了初创企业和投资者，列出了529家被称为“计算机视觉”(computer vision)的公司。这些公司的平均估值为每家520万美元。其中许多项目正处于筹资500万至1000万美元的不同阶段。可以肯定的是，有大量资金正投入到计算机视觉开发中

那么，为什么计算机视觉会如此受欢迎呢?因为在我们生活的某些方面，用电脑取代人可能会带来潜在的好处。(4)

作为人类，我们用我们的眼睛和大脑来分析我们的视觉环境。

这对我们来说很自然，我们做得很好。另一方面，计算机不能自动做到这一点。它需要算法和数据来了解它所“看到”的东西。这需要很多努力，但一旦计算机学会如何做到这一点，它就能比地球上几乎任何人类做得更好。

（补充一下啊，我个人感觉这个比较难实现，就算可以，也要有足够大的数据进行模拟修正）

D、

我的答案：ABCD

三.简答题（共1题）

What are the views of 5G exist today?

我的答案：

View 1 – The hyper-connected vision: In this view of 5G, mobile operators would create a blend of pre-existing technologies covering 2G, 3G, 4G, Wi-fi and others to allow higher coverage and availability, and higher network density in terms of cells and devices, with the key differentiator being greater connectivity as an enabler for Machine-to-Machine (M2M) services and the Internet of Things (IoT). This vision may include a new radio technology to enable low power, low throughput field devices with long duty cycles of ten years or more.

View 2 – Next-generation radio access technology: This is more of the traditional ‘generation-defining’ view, with specific targets for data rates and latency being identified, such that new radio interfaces can be assessed against such criteria. This in turn makes for a clear demarcation between a technology that meets the criteria for 5G, and another which does not.
