摘要：Sparse Learning has attracted much attention in recent years. There are two classes of methods: convex relaxation such as L1 regularization and greedy algorithms. Although the former has received more attention in the machine learning community, my opinion is that the latter approach is more flexible and powerful. This talk will discuss variations of greedy algorithms in the context of sparse recovery.

简介: Tong Zhang received a B.A. in mathematics and computer science from Cornell University in 1994 and a Ph.D. in Computer Science from Stanford University in 1998. After graduation, he worked at IBM T.J. Watson Research Center in Yorktown Heights, New York, and Yahoo Research in New York city. He is currently a statistics professor at Rutgers University. His research interests include machine learning, algorithms for statistical computation, their mathematical analysis and applications.

需要指出的是，虽然通篇充满溢美之词，但是文章最后一段作者透露出来的弦外之音，还是发人深思。建立一个有良好秩序和信用的商业体系，才是可持续发展的基础。希望随着时代进步，越来越多的中国IT从业者们不以IT民工自居，而能像美国工程师那样自豪的称自己为Professional。不论China是不是真的这么强大，我们大部分的业内人士如果不能体面、自豪地活着，那么只能说这个业界，整体还是很失败的。

Nobody questions that China is the center of the world when it comes to manufacturing. But in the last few decades, as it’s opened its economy and participated in global markets, China has also sought to become a center of high-tech innovation. It’s already proven itself a major tech player and formidable competitor. For those pursuing IT and software careers in the country, there’s a lot to be excited about.

“China is emerging as a technology power, and what comes with that is opportunity. For us, it is like a once-in-a-lifetime opportunity to be a part of it,” said Hong-Jiang Zhang, managing director of Microsoft Advanced Technology Center, chief technology officer for Microsoft Asia-Pacific Research and Development Group, and one of 10 distinguished scientists at Microsoft.

Unmatched potential

A talent base that Zhang says is on par with the US and India is one reason for the excitement about China’s technology development. Each year, a quarter-million college students graduate in China with IT degrees. Furthermore, as domestic businesses grow and multinationals like Microsoft expand operations, Zhang said many Chinese professionals who pursued education and career opportunities elsewhere are returning to help “make a difference.

China’s broad market reach is an even bigger draw. The country has 800 million mobile subscribers and 298 million Internet users, more than any other country. And it’s working hard to develop its telecommunications infrastructure, partnering with foreign firms to help expand its telecommunications networks and as restructure its domestic telecommunications industry to consolidate its previous six operators into three: China Telecom, China Mobile and China Unicom.

The country is regionally diverse, and its provinces and cities have distinct personalities that influence migration patterns, transportation and communications infrastructure, and the types of businesses and industries they can support. The market diversity, broad reach, and scale create sizeable and varied IT, Web and mobile services opportunities.
