My name is Liu Jingyong, and you can call me Jason. I’m studying for master degree in Tongji university, majoring in Computer Science.
At the first two years of my university life, I devoted myself to the major courses and got good marks. It might be a proof that I’m awarded the first-rate Scholarship twice. When I was in the third year, I realized that quite a few companies emphasize on professional skills and working eperience, therefore I put more time to improve the technique skills, such as C, CPP, Visual CPP and Java. Meanwhile I began to hunter for some relative part time jobs.
In the end of 20xx, I was recommended to study for master degree in CS Dept. without taking the entrance test. Since then, I became a member of Tongji Artificial Intelligence Lab. There, much of research work helped me cultivate the capability of analysis and problem solving. Also, I learned lots of communication skills from my colleagues, who are always willing to share their wisdom and ardor with me.
My research work in our lab includes three parts:
The first is auto-segmentation system for natural speech. We cooperate with Motorola 中国 Research Center to finish the project. Simply speaking, the system is utilized to divide the natural speech into small monophone units.
The second is Tet-To-Speech system of Mandarine. The project occupied us nearly one year and a half. Like its name, this system can transform Chinese tet to continuous speech.
The third is the research of digital watermark of audio signals. My responsibility is to research on how to embed watermark into digital audio. The research may make great sense in the copyright protection issue.
And then I would like to talk something about my technical skills.
I’m quite familiar with C/CPP/Visual CPP, and have rich eperience of programming with MFC, STL. Java is also one of my programming languages. Eclipse and JBuilder are my favorite Java IDE tools. I am also able to use Linu platform. Last year I acted as a support professional in Wicresoft Shanghai for 3 months, there I gained deep understandings of Windows platform. Some database development tools, such as SQL Server, PowerBuilder are also available to me.
My biggest merit is the self-study ability and the independency when tackling tough problems.
As we know, in IT field, technologies very quickly. It is difficult and unnecessary for us to master all of them. So the ability to study rapidly is very important when we need to use new technology which we never touch before. I think all along I am making efforts to build up this kind of qualification. For eample, once I was required to complete some modules in a Java project, but at that time I had little knowledge about it. The only way for me is to master Java as soon as possible and put what I’ve learned to practice. Within a short period, I got the key points of Java and accomplished the task assigned to me on time.
When it comes to independency, it doesn’t mean I would not like to communicate with others, but means I’m good at tackling problems independently. For eample, when I am confronted with a tough technique issue, first I will make use of all the related tools at hand, such as Google or my books, to resolve it. I will not seek others’ help at the very start without any effort to resolve it by myself.
As to the sense of responsibility, I attempt to form the habit of taking all aspects of a piece of work into consideration, analyze the advantages and disadvantages, secure that no problem would occur and responsible for what I need to complete. It is my target to keep everything going as planned and I will never give up easily.
My demerit is that sometimes I’m a little stubborn. For eample, when I’m working on a task and encounter some difficulties, maybe it is due to the wrong method that I’m using. However, I’m not inclined to give it up, because I think it is very pitiful that I have to do it again from the beginning regardless of so much work I have done. That is not a good habit. Actually, we should learn to give up or adjust the direction of the work at a proper time, and reevaluate the targets that are accessible.
I have encountered a big difficulty when implementing the TTS system. Our system is based on a large corpus. That is to say, to a Chinese character, we have plenty of choices in the database and we must find a most suitable one so that we can use it to synthesize the speech. If every time we search it from the whole list made up of the Chinese character, the efficiency of the TTS system will be unbearable. Therefore, it is urgent for me to find a good method to divide every high-frequency Chinese character into several groups. But how to divide is a big problem. I tried quite a few methods and spent a great deal of time on it. Finally, I found an algorithm called CART (Classification and Regression Trees) could meet our needs. After I introduced the CART algorithm to our TTS system, the efficiency issue was resolved. That’s the biggest difficulty I have met with during my research work.
My biggest failure is that I had to take the National College Entrance Eamination twice. The first time in 1998, I got 628 points and applied for the computer science major of Nankai university. Although my marks achieved the basic requirement of the university, I was refused by the CS major. Since I preferred the computer science very much, I didn’t accept being transferred to other majors. So, I returned to my high school with a broken heart. At that time I was really very frustrated and felt the life was so tragic. To comfort me, my parents bought a computer for me and encouraged me to confront the reality bravely. That’s my first computer in my life. In 1999, I participated in the Entrance Eamination for the second time. This time I got 644 and chose Tongji university, computer science major. I was successful to achieve my goal. Three and half years after that, when I knew I had been recommended to further study for master degree, I couldn’t help crying when I recalled this unforgettable eperience.
I’m interested in the hardware information. Pchome and Pconline are my favorite websites. In my spare time, I pay much attention to the hardware’s development. Sometimes, the outcome of a new technology will make me ecited for several days.
I also like writing articles. When I was in high school my Chinese teacher often said that I have some talent in composition. Actually I have great interest in reading and writing articles. The university life gives me more space to develop my hobby. Especially, BBS was a great platform to epress myself. When I have some special feelings, I would like to write it down and paste on BBS, share my happiness and sadness with my friends.
