Reference excerpt

Song-Chun Zhu (Chinese: 朱松纯; born June 1968) is a Chinese computer scientist and applied mathematician known for his work in computer vision, cognitive artificial intelligence and robotics. Zhu currently works at Peking University and was previously a professor in the Departments of Statistics and Computer Science at the University of California, Los Angeles. Zhu also previously served as Director of the UCLA Center for Vision, Cognition, Learning and Autonomy (VCLA). In 2005, Zhu founded the Lotus Hill Institute, an independent non-profit organization to promote international collaboration within the fields of computer vision and pattern recognition. Zhu has published extensively and lectured globally on artificial intelligence, and in 2011, he became an IEEE Fellow (Institute of Electrical and Electronics Engineers) for "contributions to statistical modeling, learning and inference in computer vision." Zhu has two daughters, Stephanie and Yi. Zhu Yi (Chinese: 朱易) is a competitive figure skater.

Early life and education Born and raised in Ezhou, China, Zhu found inspiration, when he was young, in the development of computers playing chess, sparking his interest in artificial intelligence. In 1991, Zhu earned his B.S. in Computer Science from the University of Science and Technology of China at Hefei. During his undergraduate years, Zhu, finding the computational theory of vision by the late MIT neuroscientist David Marr deeply influential, aspired to pursue a general unified theory of vision and AI. In 1992, Zhu continued his study of computer vision at the Harvard Graduate School of Arts and Sciences. At Harvard, Zhu studied under the supervision of American mathematician David Mumford and gained an introduction to "probably approximately correct" (PAC) learning under the instruction of Leslie Valiant. Zhu concluded his studies at Harvard in 1996 with a Ph.D. in Computer Science and followed Mumford to the Division of Applied Mathematics at Brown University as a postdoctoral fellow.

Career Following his postdoctoral fellowship, Zhu lectured briefly in Stanford University's Computer Science Department. In 1998, he joined Ohio State University as an assistant professor in the Departments of Computer Science and Cognitive Science. In 2002, Zhu joined the University of California, Los Angeles in the Departments of Computer Science and Statistics as associate professor, rising to the rank of full professor in 2006. At UCLA, Zhu established the Center for Vision, Cognition, Learning and Autonomy. His chief research interest has resided in pursuing a unified statistical and computational framework for vision and intelligence, which includes the Spatial, Temporal, and Causal And-Or graph (STC-AOG) as a unified representation and numerous Monte Carlo methods for inference and learning. In 2005, Zhu established an independent non-profit organization in his hometown of Ezhou, the Lotus Hill Institute (LHI). LHI has been involved with collecting large-scale dataset of images and annotating the objects, scenes, and activities, having received contributions from many renowned scholars, including Harry Shum. The institute also features a full-time annotation team for parsing image structures, having amassed over 500,000 images to date. Since establishing LHI, Zhu has organized numerous workshops and conferences, along with serving as the general chair for both the 2012 Conference on Computer Vision and Pattern Recognition (CVPR) in Providence, Rhode Island, where he presented Ulf Grenander with a Pioneer Medal, and the 2019 CVPR held in Long Beach, California. In July 2017, Zhu founded DMAI in Los Angeles as an AI startup engaged in developing a unified cognitive AI platform. In September 2020, Zhu returned to China to join Peking University to lead its Institute for Artificial Intelligence, thus joining another Chinese AI expert in the US and a long-time acquaintance of Zhu, Microsoft's former head of artificial intelligence and research, Harry Shum. Shum was also appointed by Peking University in August to chair the academic committee of the Institute of Artificial Intelligence. Zhu is working on setting up a new and separate AI research institute - Beijing Institute for General Artificial Intelligence (BIGAI). According to the introduction, based on "small data for big task" paradigm, BIGAI focuses on advanced AI technology, multi-disciplinary integration, international academic exchange, to nurture the new generation of young AI talents. The institute is expected to gather professional researchers, scholars and experts, to put Zhu's theoretical framework of artificial intelligence into practice, and jointly promoting Chinese original AI technologies and building a new generation of general AI platforms.

Research and work Zhu has published over three hundred articles in peer-reviewed journals and proceedings in the following four phases:

Worked examples

Example 1 — a first encounter with Song-Chun Zhu

Start with the simplest possible case. Write down what Song-Chun Zhu claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Song-Chun Zhu before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Song-Chun Zhu ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Song-Chun Zhu

In research: Song-Chun Zhu appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Song-Chun Zhu in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Song-Chun Zhu is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1968 births, Academic staff of Peking University, Artificial intelligence researchers, so understanding it makes those chapters shorter.
In everyday life: Look for Song-Chun Zhu outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
