The 37th AAAI Conference on Artificial Intelligence (AAAI 2023) was held in Washington, DC from February 7 to 14, 2023. Wang Qingmei and Wu Yihan, two doctoral students from Gaoling School Artificial Intelligence were invited to attend the conference due to the acceptance of their papers. They had in-depth exchanges with scholars on site about their research work.
“When your academic work fuels a heated discussion, you can feel the value and significance of what you have done.” Wu Yihan recalled. Her work “VideoDubber: Machine Translation with Speech-Aware Length Control for Video Dubbing” on AI creation was received by AAAI 2023 as an Oral Presentation and was introduced and shared in a session titled "Speech & Natural Language Processing".

Wu’s research proposes a machine translation system for the video dubbing task, which directly considers the speech duration of each word in the translation process and explicitly controls it to match the total duration of the original speech and the translated speech.
Similarly, Wang Qingmei's paper “Hierarchical Contrastive Learning for Temporal Point Processes” was also received as an Oral Presentation and was presented and shared in a session titled "Time-Series& Data Streams".
She uses a hierarchical contrast learning method (HCL) to alleviate the overfitting problem in the learning process of sequential point processes and designs a model-based sampling method to generate positive and negative sequences, reducing the computational complexity from O(N^2) to O(N).
After the report, Wang had a face-to-face communication with researchers from other countries which was a special experience for her. “Through this meeting, I can feel that I still have a lot of room for improvement in all aspects of my abilities, and there is still a long way to go if I want to reach the top of my research field.” She said.
