What is the last thing you learned about algorithms from a book, magazine or web site?

不管是书、杂志还是网络，你从中所学到的最后一点算法知识是什么？

That may be a little vague, but we will come back to this topic later when we talk about algorithms.

也许比较模糊，不过当我们不久谈论到算法的时候，我们会回来重新谈论这个话题。

The downside is that off-line experiments can evaluate a narrow set of aspects, primarily about algorithms prediction or recommendation accuracy.

该方法的缺点在于离线实验只能评测一个很狭窄的数据集切面，主要是关于算法预测或者评估的准确性。

What you're much better at doing is saying how do I take the problem I've got and map it into a class of algorithms about which I know and use the efficiencies of those to try and figure out how to make it work.

当你碰到问题的时候,更好的方法是把遇到的问题映射,到已经设计好的算法中去,并用这些算法来提高效率,来保证问题得到解决。

But I want you to take away from this how we reason about the complexity of these algorithms. And I'll remind you, we said we're going to mostly talk about time.

但是我想你们理解我们,是怎么推出这些问题的复杂度的,提醒大家，我说过了我们主要讨论时间问题。

Let me show you one more class, though about-- sorry, let me show you two more classes of algorithms. Let's look at the next one g- and there's a bug in your handout, it should be g of n and m, I apologize for that, I changed it partway through and didn't catch it.

请大家看，额,在你们的课堂材料中有个错误,应该是g，很抱歉-,我改了一部分这个错误但是没看到这里的，好，这儿的增长率，有人想猜猜么？

We can always have fun arguing about whose algorithms are better but the essence of what is being delivered is the same.

FORBES: Links 29 Nov: Google Keeps Its Word, Microsoft Attacks

Munjal Shah, a Google product manager, said the company worked with about 100 fashion taste-makers such as celebrities, stylists, and designers to pick out clothing they like and teach Google's machine-learning algorithms about their style and tastes.
