    Abstract: A method for automatically regulating an explicit congestion notification (ECN) of a data center network based on multi-agent reinforcement learning is provided. The method specifically includes steps 1 to 3. In step 1, an ECN threshold regulation of a data center network is modelled as a multi-agent reinforcement learning problem. In step 2, an independent proximal policy optimization (IPPO) algorithm in multi-agent reinforcement learning is used for training according to features of the data center network. In step 3, offline pre-training is combined with online incremental learning such that a model deployed on each switch is capable of rapidly adapting to a dynamic data center network environment.

  • 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.
