Prediction and Fitting for PM2.5 data
Spring,2015    Data Mining    Advised by Prof. ​Bo Yuan     two members group

According to the PM2.5 data from five different cities in China these years, we found that it is perfectly suit for sequential Monte Carlo method, which is also known as particle filters and usually serves for economics and finance. Based on this method, we make a good fitting modeling for the training data and one-step prediction. In addition, in order to make a better prediction, we added the environmental factors with Neutral Network method.

User Behavior Based Optimization Methodology for CloudNFV Network Architecture
​Spring,2015     Computer Network       Advised by Prof. Weijia Jia     three members group

With great development of today‘s network, Network function virtualization (NFV) gives us another chance to provide faster network service by decoupling the software implementation from hardware so that it can improve the flexibility of network service. As humorous number of users do activities through the communication network all the time, we found the distribution of user behaviors always turned to be stable during a time period. Our goal is to leverage these stable user behavior patterns to make corresponding dynamic schemes for better network performance. In this work, we set up a general system model for network optimization methodology on CloudNFV architecture with user behavior based approach. Through theoretical calculation and some simulations, it is proved to make great improvement on nodes usability, network capacity, and power consumption performances.

Chinese Word Segmentation System
Fall, 2012   Intro to Computer Science   Advised by Prof. Tianfang Yao    Four members

The application in computational linguistics is typically based on maximum matching method. Our python program is to further improve its practicability, which includes accuracy rate, time, space, appearance and so on.

To improve the accuracy rate, our team combine FMM and RMM in our program, adding frequency dictionary for every word to reduce the error rate. To improve its efficiency, some exceptions and names are also added into it, which makes the dictionary more complete and help the segmentation more and more successful. To reduce its executing time, we change the matching string into find first word in a dictionary, which achieved remarkable results.

Development of the "Be_together" Android App
​Spring, 2013   Intro to Electric Engineering B    Advised by Prof. Xinbing Wang     4 members​

 We developed an Android game application which give users a chance to interact with each other so that enhance their relationship. My main contribution of this project is taking the responsibility for User Interface and Animation. The animation function is divided into two parts. One is toNext(), which indirectly manages the picture to make the whole program running. The other is  the toShow() function, which mainly control the presentation of the two kinds of pictures, indirectly by changing the number of variable--currentType. Then we can continue to manage currentType in the program. Varied by the currentType, animation can run for next status.

Academic Search Engine
​​Fall,2013   Intro to Electric Engineering C   Advised by Prof. Ya Zhang   4 members

We built up an small academic search engine website, which mainly focus on textbooks, teaching materials, project blogs etc, as well as supporting image search. We firstly parsed some educational websites to get resource information, and then merged them and make up the index. Finally we added image search function with typical image processing algorithms.

Calculator & Breathing light on FPGA
Spring,2014    OS   Advised by Prof. Xiangzhong Fang       single person

Based on pipelined CPU structure, I added some additional MIPS instructions to implement the calculator with eight functions, such as plus, subtraction, multiplication, division, translocation, comparison, exclusive or and inclusive nor, with input from button and output on LED.

Signal Processing Software by MATLAB
Spring,2014      Signals and System        Advised by  Prof. Bin Xia         five members group

This project is for the course of Signal and System, we learned some typical signals and their properties, such as the convolution, Fourier transform, sample operation, Laplace transform and so on. In this way, we develop this system by MATLAB as a tool to show the waveform of the signals, so that we can achieve a visualized understanding of the signals.

Wireless Transmission by LABVIEW and USRP
Fall,2014     Principles of Communication     Advised by Prof. Meixia Tao    two members

Use LabVIEW and USRP digital experimental platform for the transmission of text messages. Use high sensitive packet capture mechanism for the complete digital transmission link design. Compare the difference of the packet capture sensitivity and transmission distance under the two kinds of capture mechanism of the receiver.
