Singapore A*STAR researcher Chen Zhenghua came to the school to give an academic report

On the afternoon of November 25, Nanjing University of Information Science & Technology - Zhongda Hospital Smart Medical Research Institute invited researcher Chen Zhenghua from Singapore A*STAR to the school to give an academic report. The theme of the report was “Data-Efficient and Model-Efficient Learning for Time-series Data Analytics”. Professor Xu Jun, deputy dean of the School of Artificial Intelligence (College of Future Technology) and executive director of the Smart Medical Research Institute of our school, presided over this report meeting. There were more than 30 teachers, graduate students and undergraduates participating offline and online.

Dr. Chen Zhenghua’s report mainly introduced three time series data analysis technologies from the aspects of data efficiency and model efficiency: (1) self-supervised learning; (2) domain adaptation; and (3) knowledge distillation. Dr. Chen first introduced a self-supervised learning framework suitable for time series. Different from images and NLP, this self-supervised framework introduces time and context contrast and is more suitable for learning the representation of unlabeled time series data. Then, Dr. Chen introduced the research on domain adaptation of time series signals, and demonstrated the benchmark evaluation suite ADATIME developed by his team, which provides researchers with a fair and comprehensive method to evaluate the domain adaptation of different time series. Finally, Dr. Chen introduced a heterogeneous network compression method based on knowledge distillation, and elaborated and summarized the necessity and development trends of efficient models from the perspectives of algorithms and computational energy.

During the interactive session, participating teachers and students actively asked questions and had extensive and in-depth exchanges with Dr. Chen on issues such as complex control systems, big data computing and pattern recognition, software-hardware acceleration of deep learning models, and algorithm optimization. The academic atmosphere at the venue was strong.
