2results about How to "Control deviation" patented technology

The invention relates to a number multi-dimensional risk assessment method and system based on dynamic feature extraction, and the method comprises the steps: obtaining multi-source heterogeneous telecommunication abnormal data of a client, carrying out the calculation power assessment, and carrying out the dynamic sampling according to a calculation power score, and forming a local training set; feature extraction is carried out on the text data and the image data, and multi-modal feature alignment and fusion are realized through a generative adversarial network and an attention mechanism; in a federated learning framework, dynamically adjusting a regularization coefficient according to the difference between a local model and a global model by utilizing a reinforcement learning model, and guiding a client to carry out adaptive local training; the server performs intelligent weighted aggregation on client parameters based on data quality and model similarity, and updates a global model; and finally, a user heterogeneous graph is constructed based on the global model and the multi-modal features, neighbor selection is optimized through reinforcement learning, and abnormal users are identified by using graph neural network aggregation information. According to the method and the device, on the premise of protecting data privacy, the risk assessment accuracy of the number is effectively improved.

This invention discloses a test method for determining the plastic strain ratio. By introducing the concept of a finite body and specifying the consistency of the measurement point positions before and after deformation, and using conventional measuring tools and different test conditions, the plastic strain ratio is determined, ensuring the stability of the data measurement results, improving test efficiency and reliability, and eliminating the problem of large fluctuations in the r-value measurement results caused by many uncontrollable factors in existing standards. It achieves accurate determination of the r-value in a low-cost, simple, and efficient manner. Therefore, this invention has important engineering practical significance and broad engineering application prospects.
