    Title: Theory and application of inverse source and inverse scattering problem: Geometric body generation and imaging by interior resonant modes
    Speaker: Ms HE Youzhi (何酉子), Department of Mathematics, Hong Kong Baptist University, HKSAR

    Abstract: Both inverse source and inverse scattering problem play a central role in many scientific fields with important medical, industrial and military applications. I mainly concern about the following two topics: (1) geometric body generation based on partial input parameters by the time-harmonic or time-dependent inverse source problem; (2) reconstruction of the shape of the scatterer with different physical properties by interior resonant modes. I consider both theoretical and computational perspective of these problems.

    Title: End-to-end learning for sign language recognition
    Speaker: Mr. ZHOU Mingjie (周明杰), Department of Mathematics, Hong Kong Baptist University, HKSAR
    Time/Place: 15:30  -  17:00

    Abstract: Sign language recognition is useful for bridging the communication gap between sign language users and normal hearing people. This work presents end-to-end frameworks for weakly supervised continuous sign language recognition. According to recent public data sets, these videos are not frame-by-frame labelled and these labels are noisy, which makes recognition difficult. This work will go through current literature and exploit the autoencoder, RNNs and attention-mechanism based sequence models for sign language recognition.
