Tree-of-Code: A Self-Growing Tree Framework for End-to-End Code Generation and Execution in Complex Tasks (2025.findings-acl)
Copied to clipboard
| Challenge: | Effectively and efficiently handling complex realworld problems has become a key focus across industry and academia. |
| Approach: | They propose a tree-of-code framework that generates nodes through self-supervision and combines prompt and model exploration in a GT-free setting. |
| Outcome: | Experiments on two datasets with ten popular zero-shot LLMs show that Tree-of-Code boosts accuracy by nearly 20% over CodeAct with fewer than 1/4 turns. |
SafetyMem: Adaptive Jailbreak Defense via Dual-Component Safety Memory (2026.acl-long)
Copied to clipboard
| Challenge: | Existing defenses for Large Language Models suffer from a 'memory gap' parameter-modifying methods are computationally expensive and inference-time filters cannot retain or reuse defense knowledge across interactions. |
| Approach: | They propose a framework that secures Large Language Models through a dual-component safety memory system. |
| Outcome: | The proposed framework significantly reduces attack success rates while preserving interpretability and efficiency. |
