The present invention relates to a context-aware video caching method and system, and belongs to the field of mobile edge network computing technology. First, all videos in a target community are divided into video segments of equal length, and each user device is divided into multiple virtual devices. Then, based on a multi-armed slot machine algorithm, the actual capacity of all video segments in a predicted time period is effectively predicted. Finally, the video segment is used as the device of a UCKM framework, the actual capacity of the video segment is used as the capacity of the device, and the virtual device is used as the position of the UCKM framework. With the goal of minimizing transmission delay, the video caching strategy for the predicted time period is determined, and a video caching decision can be made in real time to minimize the average delay of user devices that perform video caching in the community, so as to solve the problem that the probability of different users requesting videos of different contents is uncertain, and blind caching will cause unnecessary energy consumption and delay, thereby improving the user service quality.

This invention relates to the field of power system data analysis and energy management technology, specifically to a system and method for real-time data acquisition and forecasting of electricity user energy consumption. It collects multi-source heterogeneous data from the user side in real time, and after standardization, cleaning, and time-series alignment, fuses the data based on a unified data model to construct a correlated data cube. This allows for the construction and dynamic updating of digital twin models for electricity users, simulating their electricity consumption characteristics and market behavior. A multi-timescale collaborative forecasting mechanism is activated to generate short-term, medium-term, and long-term electricity demand and electricity market price forecasts, and to formulate trading strategies accordingly. By feeding back actual transaction and market data, the model parameters and forecasting strategies are continuously optimized. This effectively solves the problem of limited accuracy in energy consumption and market forecasting caused by insufficient fusion of multi-source heterogeneous data and lack of collaborative analysis, significantly improving the accuracy of load and electricity price forecasts.
