Sysformer: Safeguarding Frozen Large Language Models with Adaptive System Prompts

ICLR 2026poster

As large language models (LLMs) are deployed in safety-critical settings, it is essential to ensure that their responses comply with safety standards. Prior research has revealed that LLMs often fail to grasp the notion of safe behaviors, resulting in either unjustified refusals to harmless prompts…

MAIN-RAG: Multi-Agent Filtering Retrieval-Augmented Generation

ACL 2025long

Large Language Models (LLMs) are becoming essential tools for various natural language processing tasks but often suffer from generating outdated or incorrect information. Retrieval-Augmented Generation (RAG) addresses this issue by incorporating external, real-time information retrieval to ground L…

Probabilistic Masked Attention Networks for Explainable Sequential Recommendation

IJCAI 2023poster

Transformer-based models are powerful for modeling temporal dynamics of user preference in sequential recommendation. Most of the variants adopt the Softmax transformation in the self-attention layers to generate dense attention probabilities. However, real-world item sequences are often noisy, cont…
