Are the Values of LLMs Structurally Aligned with Humans? A Causal Perspective

ACL 2025finding

As large language models (LLMs) become increasingly integrated into critical applications, aligning their behavior with human values presents significant challenges. Current methods, such as Reinforcement Learning from Human Feedback (RLHF), typically focus on a limited set of coarse-grained values…

ReflectEvo: Improving Meta Introspection of Small LLMs by Learning Self-Reflection

ACL 2025finding

We present a novel pipeline, ReflectEvo, to demonstrate that small language models (SLMs) can enhance meta introspection through reflection learning. This process iteratively generates self-reflection for self-training, fostering a continuous and self-evolving process. Leveraging this pipeline, we c…

Labels Need Prompts Too: Mask Matching for Natural Language Understanding Tasks

AAAI 2024technical

Textual label names (descriptions) are typically semantically rich in many natural language understanding (NLU) tasks. In this paper, we incorporate the prompting methodology, which is widely used to enrich model input, into the label side for the first time. Specifically, we propose a Mask Matching…

Varying Sentence Representations via Condition-Specified Routers

EMNLP 2024main

Semantic similarity between two sentences is inherently subjective and can vary significantly based on the specific aspects emphasized. Consequently, traditional sentence encoders must be capable of generating conditioned sentence representations that account for diverse conditions or aspects. In th…
