News (More)

May 21, 2021 Probabilistic Delta Debugging and A Syntax-Guided Edit Decoder for Neural Program Repair were accepted at ESEC/FSE'21. The former proposes the first delta debugging based on probabilistic modeling and significantly outperforms the classic ddmin algorithm. The latter proposes the first neural program repair approach that outperforms traditional non-neural program repair approaches.
December 1, 2020 I received the NASAC Software Innovation Award for Young Researchers and ESEC/FSE 2020 Distinguished Reviewer Award. Thanks for the recognition from the award committees and the nominators!
October 1, 2020 Guiding Dynamic Programming via Structural Probability for Accelerating Programming by Example was accepted at OOPSLA'20. Following our previous work that uses probability to guide enumerative search, this paper uses probability to guide FlashFill-style dynamic programming, and achieved 4x-2000x speedup over the state-of-the-art synthesizers.
August 21, 2020 Detecting Numerical Bugs in Neural Network Architectures was rewarded ACM SIGSOFT Distinguished Paper Award at ESEC/FSE'20. Thanks for the recognition.
June 2, 2020 I was recognized as a distinguished reviewer by ICSE 2020. Thank all subreviewers who contributed to the reviews. Thank the ICSE organization committee for the recognition.
