| Challenge: | Recent approaches to optimize communication topology rely on single-sample policy gradients with absolute rewards. |
| Approach: | They propose a topology optimization framework that integrates Group Relative Policy Optimization. |
| Outcome: | The proposed topology optimization framework outperforms state-of-the-art methods on reasoning and code generation benchmarks. |
DINT Transformer (2025.emnlp-main)

| Challenge: | Experimental results show that the DINT Transformer improves accuracy and robustness across practical applications. |
| Approach: | They propose a differential attention mechanism that suppresses the impact of irrelevant contexts by computing DIF-Ference between two independent attention distributions. |
| Outcome: | The proposed architecture improves numerical stability and ability to capture global dependencies. |
