Luyi Chen’s blog

There’s a report in today’s SJTU news about the just launched Information Security Service Platform. Formerly, it’s in this place. I used to be a core member of this project, responsable for content security angle.

Today I noticed there’s a new design of SJTU homepage. The texts are more readable. And it supports firefox now.

Jiang have come to SJTU. He said four points. Worth read.

I am helping Stanford ATI to do fellow recruitment this year. In this post I will dump some information about the program, so I can link to this from other places later.

What is Stanford ATI?

ATI is a student organization in Stanford. Accompanied by a course in enigeering school, ATI sends out 6 to 8 students to Asia companies do global internship every year in summer since 1999. They also select the same ammount of local students to help Stanford students to finish their overseas programs.

Local students will team with Stanford students to attend summer internship and help with the annual conference. This is an oppertunity for local students to cooperate with foreign students and learn how to do an overseas program.

Who am I?

My name is Chen Luyi. I am graduating PhD student in SJTU. I am one of the ATI co-directors in Shanghai this year. I will be responsible for seeking qualified local students and help them perform well in the program. I was an ATI fellow two years ago.

How to apply?

This is not a job recruitment. So a formal resume is not necessary. But if you send me, I will read it carefully. What’s more, I would like you to write a short application letter including the following points:

1. What’s you unique qualification? This is important to standing out from your peers and forming the teams afterwards.
2. Do you have any experience to show us that you have great understanding of entrepreneurship and full of ideas? We want you to provide more details in this section.
3. Please describe a new idea about anything, for example a new web2.0 startup or anything else. I would like to know how you refine your ideas. So it doesn’t have to be a finished proposal. Only some analysis is enough.
4. Tell me what have you learned about ATI and its history. Yes, I know we haven’t prepare a good homepage for you. But if you want to join us, you should collect some information about the program first. There are lots of tools out there, like google and technorati, etc. After you have done these homework, and you still want to join. Great, welcome!

The application to me is limited to SJTU students. We will select 2 students from SJTU this year. (My email is lychen@sjtu.edu.cn)

So any open question should post to ati2006sjtu group. Before you post, please search old posts first.

Disclaimer: What I wrote about ATI in my blog only represent my personal thoughts. They are not official annoucement from Stanford ATI.

This Monday, I listened to Biing-Hwang (Fred) Juang’s speech, who is from Georgia Institute of Technology. You can find the news on our school’s website. The title of the speech is Prospects of Speech & Multimedia Research For The New Digital Era. Here is some notes of his talk.

Speech Research

Fred said there is a paradigm shift in speech synthesis. Storage prise becomes cheaper today, and this makes speech synthesis no use, because we can just store all the words that we need in advance.

Then he gave a demo on text-to-speech. It was a email reading program. He first gave a traditional version, which sounds quite machine-ish. Then a much better version similar to real human. The challenge is to let computer understand the document.

Went on, Fred brought forward the quesion: Speech recognition is a language problem or just a math or signal processing problem?

The math model has reached its limitations. In comparison of human Vs. machine, human often does better job. He mentioned two approach: 1) Biological approach; 2) more interaction. Interaction means to give more steps for machine to tweak the result.

In the future of speech research, Fred said speech technology is of human, it should beyond simple conversion between sound and text.

Media Research

Fred first introduced some new telecom paradigm: Ubiquitous computing; converged digital services; right content, right person, right context.

Then he quickly reviewed some of the research project in GIT.

• Spatialization & the perceptual dimension. He gave a demo of Multi-channel system, transmiting voices of a male and a female at the same time.
• Content processing. They are using region of interest to solve low resolution on mobile devices.
• Embedded and Layered coding. They are using multi-stream coding to deal with high bit error.

In summary, these are the things in the center of future telecom research.
