Cooperative Behaviour for Model Training with Autonomous Mobile Robots
In order to gain the benefits of supervised learning techniques without requiring a human to construct a labeled dataset, we have developed a behavior for a pair of mobile robots to train a visual classifier on their own. This autonomous approach takes advantage of the rote nature of dataset creation to allow machines to replace humans with little appreciable loss of performance. A specific implementation of this behavior was written for Chatterbox robots, whose automatically-built dataset was compared to human-constructed ones.
Orbiting a Moving Target with Multi-Robot Collaborative Visual SLAM
Towards autonomous 3D modelling of moving targets, we present a system where multiple ground-based robots cooperate to localize, follow and scan from all sides a movingtarget. Each robot has a single camera as its only sensor, and they perform collaborative visual SLAM (CoSLAM). We present a simple robot controller that maintains the visual constraints of CoSLAM while orbiting a moving target so as to observe it from all sides. Real-world experiments demonstrate that multiple ground robots can successfully track and scan a moving target. (video)
3D Mesh Segmentation Based on cascaded algorithm for super-patch agglomeration
I interned for the Special Interests Group on Visual Computing (SIGVC) at Chinese Academy of Science. I worked with Dr. Huaiyu Wu, doing research on 3D mesh segmentation, applying cascaded algorithm for super-patch agglomeration. (Note: the thumbnail image is from here)
the Visualization of the Deep Learning Process
I joined the deep learning research in the National University Science Park of BUPT as a research assistant for Dr. Da Xiao from 2013.07 to 2013.10, using the Theano and Pylearn2. With MNIST and Cifar-10 Image Dataset, I visualized the mapping from the features of input data to the units in hidden layers. I learned GPU programming, which could accelerate the calculation speed to 100 times what CPU is capable of, through applying Theano and Pylearn2 in this project .
Improving Collaborative Filtering Algorithm for VOD System
I worked with Pro. Guo in Communication Network Lab of my school from 2013.02 to 2013.07. The goal was to improve the performance of traditional Collaborative Filtering Algorithm for the video recommender system. I, together with my partner, promoted the QoS, which was based on the video watching time, as a factor during the machine learning process and got a better recommendation result, evaluated by NDCG and MSE, than the one without QoS factor.
Video Recommender System Algorithm Research Based On ABS
My job was to build up the simulation platform for Agent Based Simulation on Netlogo. I learned Netlogo programming and finished this platfrom myself. The selection tactics of the audience can be controlled and feedback can be collected to enhance the performance of the recommender system.(more about this)

Students’ Community Work:
Founder and the 1st President of Beijing Jiaotong University Scientific English Association:
In 2012, I instituted the Scientific English Association in our university, aiming at propagating knowledge and enhancing academic exchange and communication. We held public speaking contests as a premature form of TEDx and look forward to holding an official TEDx in the near future. We also held cocktail parties for the future engineers and scientists to exchange brilliant ideas. We invited a myriads of successful people to give lectures and share their experience.(more about this)
Vice Captain of the School Debate Team:
I, being the vice president of the school debating team, am deeply in favor of this activity as I find it means more than itself. On the one hand, it enhanced the skills of public speaking, facilitating expressing myself in various occasions. On the other hand, it forces me to think critically and logically, equipping an even more clear mind.
Director of the School Students’ Union Office:
The School Students’ Union Office is the core of a whole students’ union. Our work was to make plans for different departments of the students’ union so that they could coorperate with each other effectively. And we kept the documentation for all the members and event details of the students’ union.
‘You are what you read’. Literature, history, economy, politics, phsycology and computer science related books are all I loved. Sometimes, I wrote book notes after reading and some of them are on this website.(more about this)
I enjoy various kinds of music ranging from classic music to rock music. I am a guitar player and I also covered some famous songs by my self.(more about this)
I learnt and practiced sketching at a young age for one year. After that, I drew all kinds of things by myself. Since last year, I started to paint with electronic devices, such as smart phones and Ipad, using an app called SketchBook Mobile. (more about this)
About this blog:
This blog is an inherit of http://blog.csdn.net/lethic. I had a good time at CSDNs blog, but it would be better to find a place of my own. This new blog contains five main categories: Algorithm, Programming, Tech, Words & Music, Work & Life, which may be chaned by time.
- Algorithm is a collection of programming algorithm study experience and some interesting problems solving report.
- Programming contains some notes of learning programming.
- Tech is the page for Data mining, Machine Learning, Microcontroller, Embedded System, Linux, Internet and etc..
- Words and Music may be the most interesting part. I love reading literature and history related books. At the same time, Im a rock music fan. So some critics to books and music will be included.
- Work and Life is where I write about my sentiment about my work in some students community and some essay in the daily life.
