The Center for Vision, Cognition, Learning, and Autonomy (VCLA) is affiliated with the Departments of Statistics and Computer Science at UCLA. We start from Computer Vision and expand to other disciplines. Our objective is to pursue a unified framework for representation, learning, inference and reasoning, and to build intelligent computer systems for real world applications.
Professor Wu is a professor of Statistics in University of California, Los Angeles. He is interested in statistical modeling, computing and learning. In particular, he is interested in generative models and unsupervised learning.

ACM Honored Class is a pilot computer science class in China.
Over the past 10 years, ACM students have received hundreds of honors and awards. ACM studnets won the ACM International Student Programming Contest World Championship for three times in 2002, 2005 and 2010.
ACM students has published more than 40 academic papers as the first author in the NIPS, WWW, SIGIR, SIGMOD, SIGKDD, ICML, AAAI and other important international conferences and journals.
Zhiyuan College, within Shanghai Jiao Tong University, is an institude that provides an Elite-education for our students. It aims to train them to become future leaders in science and in technology.
In order to be admitted to Zhiyuan College, a student must be on the top fo more than 17,000 undergraduate students within SJTU. Currently, 461 students are enrolled in Zhiyuan College.
By September 2016, 359 students have graduated from Zhiyuan College, 327 (91%) to pursue further studies, 273 (76%) admitted by world top 100 University listed in QS World University Ranking 2016, and 250 (70%) to pursue Ph.D. degrees.
Shanghai Jiao Tong University (SJTU), as one of the higher education institutions which enjoy a long history and a world-renowned reputation in China, is a key university directly under the administration of the Ministry of Education (MOE) of the People's Republic of China and co-constructed by MOE and Shanghai Municipal Government. SJTU has become a comprehensive, research-oriented, and internationalized top university in China.
GPA: 3.83 / 4.0 (Major GPA) (A+ = 4.3)
The CSST office administers the CSST Summer Program which brings outstanding third year undergraduate students, interested in PhD studies, nominated by top-tier universities in the People?s Republic of China (PRC) and Japan, to conduct 10 week intensive research training with UCLA faculty mentors. This 10-week program offers emerging scholars premier research training in a cutting edge scientific environment that fosters cross-disciplinary collaborations.

This paper proposes an alternating back-propagation algorithm for learning the generator network model. The model is a non-linear generalization of factor analysis. In this model, the mapping from the latent factors to the observed vector is parametrized by a convolutional neural network. The alternating back-propagation algorithm iterates between the following two steps: (1) Inferential back-propagation, which infers the latent factors by Langevin dynamics or gradient descent. (2) Learning back-propagation, which updates the parameters given the inferred latent factors by gradient descent.
This paper proposes a framework for generative learning of hierarchical structure of visual objects, based on training hierarchical random field models. The resulting model, which we call structured sparse FRAME model, is a straightforward variation on decomposing the original sparse FRAME model into multiple parts that are allowed to shift their locations, orientations and scales, so that the resulting model becomes a reconfigurable template.
This is a competition hold by Alibaba. The goal is to output the picture with the most similarity by the given picture. The database is a million web pictures. There are three part for our model. They are saliency detection, CNN classification and text matching. I am in charge of saliency detection and classification. Our team ranked in the top 16 in the competition(Over 2000 teams).
This paper proposes a novel approach to meet users' multi-dimensional requirements in clothing image retrieval.We propose the Hybrid Topic (HT) model to learn the intricate semantic representation of the descriptors above. The model provides an effective multi-dimensional representation of clothes and is able to perform automatic image annotation by probabilistic reasoning from image search. Furthermore, we develop a demand-adaptive retrieval strategy which refines users' specific requirements and removes users' unwanted features. Our experiments show that the HT method significantly outperforms the deep neural network methods.
This work is based on "Joint cascade face detection and alignment" and "Unconstrained Face Alignment via Cascaded Compositional Learning". We aim to provide domain partition on the Joint cascade face detection and alignment method.
