January 7, 2022 The videos of my talk on algorithm synthesis and my tutorial on inductive program synthesis (both in Chinese) are available in the CCF digital library. Please check the invited talks page for the links.
December 20, 2021 Three papers accepted at ICSE 2022 and AAAI 2022. Fault Localization via Efficient Probabilistic Modeling of Program Semantics is our first attempt to use a probabilistic graphical model to capture program semantics to build fault localization afresh. Preferential Labeling for Unattributed Node Classification in GNNs concerns, when a classification task should be insensitive to variable names (e.g., SAT), how to represent programs in graph neural network. Improving Machine Translation Systems via Isotopic Replacement is a testing and repairing approach for machine translation.
October 11, 2021 L2S: a Framework for Synthesizing the Most Probable Program under a Specification was accepted at TOSEM. This paper presents L2S framework, which guides program synthesis with probabilities and captures the core underline ideas of many our other papers. This work started as a generalization and extension of our ACS approach at the end of 2016. In 2018 we wrapped up the initial ideas and experiment results as a workshop paper. Finally, after almost five years' work, after numerous invited talks and keynotes at workshops and conferences about L2S, and after the publications of multiple other papers based on the framework, we finally managed to publish the full L2S framework. The final paper has 44 pages excluding the appendix.
October 2, 2021 Interactive Patch Filtering as Debugging Aid was awarded IEEE TCSE Distinguished Paper Award. Thanks for the recognition.
September 30, 2021 I received the CCF-IEEE CS Young Computer Scientists Award. This award is given to at most 5 young computer scientists in China under the age of 40 each year. Thank nominators and the award committee for the nomination and recognition.
