Mapping Smarter, Not Harder: A Test-Time Reinforcement Learning Agent That Improve Without Labels or Model Updates (2025.emnlp-industry)
Copied to clipboard
| Challenge: | a new agent that can improve schema mappings for third-party logs is needed for enterprise intelligence platforms. |
| Approach: | They propose a reinforcement learning agent that can self-improve without labeled examples or model weight updates. |
| Outcome: | The proposed method increases mapping accuracy from 56.4% (LLM-only) to 72.73% (RAG) to 93.94% over 100 iterations using GPT-4o. |
Primus: A Pioneering Collection of Open-Source Datasets for Cybersecurity LLM Training (2025.emnlp-main)
Copied to clipboard
| Challenge: | Large Language Models (LLMs) have shown remarkable advancements in specialized fields such as finance, law, and medicine. |
| Approach: | They propose to provide datasets covering all major training stages including pretraining, instruction fine-tuning, and reasoning distillation with cybersecurity-specific self-reflection data. |
| Outcome: | Extensive ablation studies show that LLMs acquire their knowledge during pretraining, while reasoning distillation leads to a 15% gain in security certification (CISSP). |
Breaking the Ceiling of the LLM Community by Treating Token Generation as a Classification for Ensembling (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Large Language Models (LLMs) have demonstrated remarkable capabilities in a wide range of tasks and contexts. |
| Approach: | They propose to use a token-level ensembling method to exploit the probability information at each generation step and to avoid early incorrect tokens. |
| Outcome: | The proposed method breaks the existing community performance ceiling and improves on several benchmarks. |
PathwiseRAG: Multi-Dimensional Exploration and Integration Framework (2025.emnlp-main)
Copied to clipboard
| Challenge: | Existing retrieval-augmented generation systems employ rigid retrieval strategies . static retrieval produces knowledge blind spots, missing connections between quantum algorithms and encryption vulnerabilities . |
| Approach: | PathwiseRAG addresses these challenges through intent-aware strategy selection . it constructs a directed acyclic graph of interconnected sub-problems and explores multiple reasoning trajectories . |
| Outcome: | The proposed framework achieves higher accuracy and better reliability than current systems. |
