Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face limitations in inferring battlefield situations from multi-modal data collected by multiple agents, particularly in dynamic combat environments, due to high computational complexity and inefficiencies in determining agent similarity and inferring global battlefield scenarios.
Innovation Solution

Engineering Contradiction Analysis
1Measurement precision
If graph neural network is used to train agent embedding vectors, then embedding vectors between adjacent nodes become similar, but it is difficult to obtain embedding vectors representing agents themselves including several nodes and graphs
Solution Approach 1:
The patent merges multiple graph structures (individual agent graphs) into a global knowledge graph that represents the entire multi-agent system. This combining approach allows the system to capture both local node similarities and global agent representations simultaneously, resolving the contradiction between adjacent node similarity and comprehensive agent representation.
Solution Approach 2:
The patent implements a nested structure where individual agent knowledge graphs are embedded within a global knowledge graph. Each agent's graph contains nodes and edges representing that agent's observations and relationships, while the global graph nests these individual graphs to represent the complete multi-agent battlefield environment, enabling hierarchical representation from local to global levels.
2Measurement precision
If clustering methods are used to find similar agents, then agents with high similarity can be identified, but computational complexity becomes very high and clustering must be repeatedly performed when new agents are added
Solution Approach 1:
The patent performs preliminary action by pre-computing and storing embedding vectors for all agents in the global knowledge graph. When new agents are added or similarity queries are needed, the system can efficiently compute similarities using these pre-computed embeddings without performing full clustering, significantly reducing computational complexity and enabling scalable real-time operation.
3Measurement precision
If existing technologies are used for multi-agent embedding, then agent similarity can be determined, but speed and accuracy are insufficient for regiment/division/corps-level battlefield situation awareness
Solution Approach 1:
The patent segments the battlefield situation awareness task into hierarchical levels (regiment-level, division-level, corps-level) corresponding to different scopes of the global knowledge graph. This segmentation allows the system to process and infer situations at appropriate granularities, improving both speed by avoiding unnecessary computation at higher levels and accuracy by maintaining detailed representations at lower levels.
