  • Patent number: 11916866
    Abstract: A computer-implemented framework and/or system for cyberbullying detection is disclosed. The system includes two main components: (1) A representation learning network that encodes the social media session by exploiting multi-modal features, e.g., text, network, and time; and (2) a multi-task learning network that simultaneously fits the comment inter-arrival times and estimates the bullying likelihood based on a Gaussian Mixture Model. The system jointly optimizes the parameters of both components to overcome the shortcomings of decoupled training. The system includes an unsupervised cyberbullying detection model that not only experimentally outperforms the state-of-the-art unsupervised models, but also achieves competitive performance compared to supervised models.

  • Publication number: 20240064416
    Abstract: An optical sensor, for sensing a sensing frame corresponding to a flicker period of ambient light, comprising: a pixel array, configured to perform N times of exposure operations via at least one pixel of the pixel array in N exposure time intervals to generate N sub-frames, wherein a summation of the N exposure time intervals equals to a sensing interval and the sensing interval is less than or identical to a first flicker period. The optical sensor adds the N sub-frames to generate a summing sub-frame. The sensing frame comprises the summing sub-frame. The adding operation can also be performed to digital signals generated from the sub-frames. The influences caused by the fluctuation of ambient light can be neutralized, since the frame or portion of the frame is sensed at least twice at different phases of a single flicked period. By this way, the conventional flicker issue can be improved.
