Conglong Li
Conglong Li is a fifth-year Ph.D. student
in Computer Science Department
at Carnegie Mellon University advised
by Professor David G. Andersen.
He received both B.S. and M.S. in Computer Science
from Rice University in 2013 and 2014,
respectively. During his M.S. study, he was advised
by Professor Alan L. Cox and
supported by the Graduate Research Fellowship.
In general, Conglong works on improving performance and resource efficiency of various
computer systems with a focus on algorithms and data structures.
In particular, he is focusing on the intersection of systems and machine learning:
- Systems for ML: building efficient systems for ML applications.
- ML for Systems: leveraging ML techniques to build intelligent systems.

Internship
- Summer 2019 Research Intern at Microsoft AI & Research.
Mentor: Yuxiong He.
Worked on improving approximate nearest neighbor search performance (this project
started in 2018). Designed ML models (GBDT) to predict the search termination
condition for each query. Evaluations demonstrate up to 10.8 times speedup under
the same accuracy targets. Submitted a paper to a top tier conference. Working on
publishing the code and shipping it in Microsoft products.
- Summer 2017 Software Engineer Intern at Microsoft AI & Research.
Mentor: Ramu Movva, Yuxiong He.
Worked on designing caching strategies for Bing Ads. Designed ML models (GBDT) to
provide intelligent cache refresh decisions. Simulations on production traces demonstrate
a potential 35.2 to 106.1 million dollars net profit gain in a quarter. Transferred the
project to developing team to ship it in product. Project ended up with a paper published
at WWW 2018.
- Summer 2016 Research Intern at Microsoft Research.
Mentor: Yuxiong He, Ramu Movva.
Worked on designing caching strategies for Bing Ads. Designed domain-specific caching
heuristics to save ads selection cost and improve net profit. Simulations on production
traces demonstrate a potential 20.7 to 70.5 million dollars net profit gain in a quarter.
Project ended up with a paper published at SoCC 2017.
