Reference excerpt

Yan Liu (刘燕） is a computer scientist whose research focuses on machine learning for time series, explainable machine learning, physics-informed AI, and their applications to climate modeling, transportation planning, social media, and biomedicine. She is Fletcher Jones Foundation Endowed Chair Professor in the Departments of Computer Science, Electrical and Computer Engineering, and Biomedical Sciences in the USC Viterbi School of Engineering of the University of Southern California.

Education and career Liu received a bachelor's degree in 2001 from the Peking University Department of Computer Science and Technology. She continued her studies in computer science at Carnegie Mellon University, where she received a master's degree in 2004 and completed her Ph.D. in 2007. Her dissertation, Conditional Graphical Models for Protein Structure Prediction, supervised by Professor Jaime Carbonell, received the honorable mention of ACM Doctoral Dissertation Award. She was a research staff member at IBM Thomas J. Watson Research Center in Yorktown Heights, New York, from 2006 to 2010. In 2010 she joined the University of Southern California as an assistant professor of computer science. She was promoted to associate professor in 2016, and promoted to full professor in 2021. She was a visiting faculty at Google in 2022 to 2023, and is currently an Amazon Scholar.

Recognition Liu was named to the 2026 class of IEEE Fellows, "for contributions to the methodology and application of machine learning and data mining". She was also named as AAAI Fellow, for "significant contributions to machine learning and development of widely recognized models for time series and spatiotemporal data analysis".

Worked examples

Example 1 — a first encounter with Yan Liu (computer scientist)

Start with the simplest possible case. Write down what Yan Liu (computer scientist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, 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 Yan Liu (computer scientist) 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 Yan Liu (computer scientist) 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 Yan Liu (computer scientist)

In research: Yan Liu (computer scientist) appears in computer science 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 Yan Liu (computer scientist) 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: Yan Liu (computer scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics American computer scientists, American women computer scientists, Carnegie Mellon University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Yan Liu (computer scientist) 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.
