    • SIGKDD Explorations (the December 2023 issue is accepting submission of surveys, news, opinion papers, vision papers and so on).

Nov 2022

  • We have 5 papers accepted by AAAI 2023! Congratulations to Zhenwen, Qiannan, Hongyan, Xiuying and Xiaoting! These papers present our recent study of data-efficient learning from graphs, trustworthy machine learning and natural language understanding. More can be found here.

Aug 2022

  • NSF Center for Computer-Assisted Synthesis led by Prof. Olaf Wiest is funded! In the 5-year project, PI Dr. Zhang’s team will work on designing novel machine learning models for chemical research problems.
  • We have another molecular generation paper got accepted by CIKM 2022. It attempts to build an understandable embedding space for molecular generation.

Aug 2022

  • We have two papers about Recommendation Systems got accepted by CIKM 2022.
    • One designs a novel zero-shot learning model for cold-start news recommendation.
    • The other investigates the negative sampling issue in the optimization process of recommendation systems, and proposes a fast dynamic negative sampler for the personalized ranking task.
    • More of our recent work in this topic can be found at Recommendation Systems.
  • Dr. Zhang is appointed as the Editor-in-Chief of ACM SIGKDD Explorations. Welcome submissions!

May 2022

  • Our work of Few-shot Heterogeneous Graph Learning via Cross-domain Knowledge Transfer is accepted by KDD 2022. Anther few-shot learning on graphs survey paper will appear in IJCAI 2022
  • Our work of applying PU-learning on graph completion, Positive-Unlabeled Learning with Adversarial Data Augmentation for Knowledge Graph Completion will also appear in IJCAI 2022
  • More of our recent work on graph learning can be found at Learning with Graphs.

January 2022
