Papers with dual-path design
HeLa-Mem: Hebbian Learning and Associative Memory for LLM Agents (2026.acl-long)
Copied to clipboard
| Challenge: | Existing memory systems represent conversation history as unstructured embedding vectors, retrieving information through semantic similarity. |
| Approach: | They propose a bio-inspired memory architecture that models memory as a dynamic graph with Hebbian learning dynamics. |
| Outcome: | The proposed architecture leverages both semantic similarity and learned associations . it can be used to build a bio-inspired memory graph with Hebbian learning dynamics . |
LoRA-Guard: Parameter-Efficient Guardrail Adaptation for Content Moderation of Large Language Models (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing model-based guardrails have not been designed for resource-constrained computational portable devices such as mobile phones. |
| Approach: | They propose a parameter-efficient guardrail adaptation method that relies on knowledge sharing between LLMs and guardrail models to adapt to content moderation tasks. |
| Outcome: | The proposed method outperforms existing guardrail methods with lower parameter overhead and higher accuracy on the generative task. |
