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.

Abstract: Disclosed is a base plate assembly for use in mounting a die-stone dental replica, the assembly including a base plate that has a configuration commensurate with at least one dental quadrant, and having a planar upper surface characterized by an array of transverse elongate rectangular sockets. A plurality of mounting blocks are assembled in side-by-side relationship along the plate planar surface, each block having a downward projection adapted to frictionally and releasably hold the block on the base plate, and extending from the tops of the blocks are anchoring tabs designed to be embedded in the wet positive mold of a dental impression and affixed therein when the mold material cures. In a preferred embodiment, the base plate has a modular configuration and is interconnectable with an identical modular unit to form a combined base plate having a configuration commensurate with full bilateral upper or lower dental quadrants.
