A system and method are described that dynamically alter hierarchical data structures displayed on a user interface. The system accesses data associated with a plurality of assets, each having a value and binary attributes, and constructs a directed graph comprising vertices and edges based on those attributes. An active core of the graph is determined by analyzing vertex values and selecting a subset of vertices and edges in accordance with user input. The display is updated to reflect the active core, and edge filters and edge score evaluations (ESEs) are applied to refine the selected edges for inclusion. The transitive edge removal policy (TERP) ensures that undesired transitive edges are removed from the structure. The display dynamically updates over time to reflect changes in the underlying data, enabling users to interact with and modify the graph structure based on new insights and changing conditions.

This invention discloses a global neural rendering method and system based on controllable neural optical transmission sparse inference, which can be deployed in real-time graphics systems that support neural rendering inference, such as game engines, interactive visualization systems, or hybrid rendering frameworks. During frame-by-frame rendering, the method combines the geometric attribute information of the current frame, historical intermediate features, and historical rendering frames as output results. It sequentially performs adaptive hierarchical feature querying, geometrically constrained intermediate feature super-resolution reconstruction, temporal error-driven sparse decoding, and temporal synthesis based on fused intermediate features to output a complete current rendering frame image and saves relevant historical states for use in the next frame. By jointly modeling spatial detail complexity and temporal reuse risks, computational resources are concentrated on regions with a greater impact on the quality and temporal stability of the current frame, achieving continuous adjustment of quality and overhead under a limited real-time budget.
