Best Student Paper Award
MDM, 2023, CCF-C.
Area: IP Geolocation, Robustness, and Adversarial Training.
We present RipGeo for robust street-level IP geolocation. Furthermore, considering the widespread noise in measurement data, we propose two novel self-supervised perturbational training strategies to enhance the generalization and robustness of the model. Besides, a multi-task learning framework is introduced to solve the homogenized representation problem caused by perturbational training.

AAAI, 2024, CCF-A.
Area: Speech Enhancement and Diffusion Models.
We propose SDFEN to address the inefficiency problem while enhancing the quality of generated samples by reducing the iterative steps in the reverse process of diffusion method. Specifically, a shallow diffusion strategy is introduced to initiate the reverse process with an adaptive time step to accelerate inference.
