MAGIC: Deep Geometric Evolution with Structural Consensus for Temporal Knowledge Graph Reasoning (2026.acl-long)
Copied to clipboard
| Challenge: | Existing multi-geometry approaches face two key bottlenecks: Riemannian depth barrier and gate collapse. |
| Approach: | They propose a framework for Temporal Knowledge Graph reasoning that integrates a Tangent-Residual Engine into multi-geometric spaces to regulate gradient flow and prevent collapse. |
| Outcome: | The proposed framework improves state-of-the-art in TKG reasoning by up to 2.9 points. |

| Challenge: | Existing methods for strategic reasoning face challenges in adaptability, scalability, and transferring strategies to new contexts. |
| Approach: | They propose an explicit policy optimization model that provides strategies in open-ended action space and can be plugged into arbitrary LLM agents to motivate goal-directed behavior. |
| Outcome: | The proposed model provides strategies in open-ended action space and can be plugged into arbitrary LLM agents to motivate goal-directed behavior. |
SAMem: State-Aware Memory as a Fine-Grained Memory for LLM Agents in Decision-Making (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing experiential memory approaches rely on task-level memory, but this lacks the situational alignment required for complex multi-step decision-making. |
| Approach: | They propose a new fine-grained memory paradigm that aligns memory retrieval with the current state instead of storing and reusing globally shared experiences. |
| Outcome: | Experiments on complex decision-making benchmarks show that the proposed state-aware memory outperforms existing experiential memory approaches and significantly improves task-solving efficiency. |
