This invention discloses a multi-level context compression method and system, belonging to the field of information processing technology. Before performing multi-level compression, the method first performs semantic pre-screening, using a lightweight embedding model to evaluate the information entropy and semantic importance of messages, achieving context-aware dynamic budget allocation. Then, it performs multi-level compression sequentially: the first level is content budget control, which enforces an upper limit on the aggregated content size of each message before lightweight compression; the second level is fragment compression, selectively removing historical content with feature gating; the third level is lightweight compression, performing lightweight content compression and supporting delayed boundary message processing; the fourth level is context folding, performing fine-grained selective compression based on the dialogue state graph, retaining key decision nodes; and the fifth level is complete summarization, performing a complete content summary when resource usage exceeds a threshold. This invention also introduces reinforcement learning optimization, dynamically adjusting the compression strategy based on task completion rate feedback. This invention achieves a strategy that prioritizes fine-grained compression over coarse-grained summarization, differential compression based on semantic importance, topological compression based on graph structures, and adaptive strategy optimization.

This invention discloses a minimally invasive and controllable processing device for wheat grain skin, comprising: a feeding unit for storing wheat grains and discharging individual grains; a conveying unit for receiving wheat grains discharged from the feeding unit and driving them along a preset path in a single-grain carrying manner; a stress application unit for applying stress to the wheat grains on the conveying unit, causing cracks to form on the wheat grain skin; a visual inspection unit for acquiring and recognizing images of the wheat grains processed by the stress application unit to determine whether the crack formation state of the wheat grain skin meets the standards; and a rejection unit configured to reject unqualified wheat grains based on the detection results of the visual inspection unit, thus completing the sorting of qualified wheat grains. This invention achieves automation and precision in minimally invasive processing of wheat grain skin, greatly improving work efficiency, while also ensuring high consistency of the processed wheat grains, facilitating experiments.
