CLIP-MoE: Towards Building Mixture of Experts for CLIP with Diversified Multiplet Upcycling

EMNLP 2025

Contrastive Language-Image Pre-training (CLIP) has become a cornerstone in multimodal intelligence. However, recent studies discovered that CLIP can only encode one aspect of the feature space, leading to substantial information loss and indistinctive features. To mitigate this issue, this paper int

Dynamic Data Mixing Maximizes Instruction Tuning for Mixture-of-Experts

NAACL 2025long

Mixture-of-Experts (MoE) models have shown remarkable capability in instruction tuning, especially when the number of tasks scales. However, previous methods simply merge all training tasks (e.g. creative writing, coding, and mathematics) and apply fixed sampling weights, without considering the imp…

Incentivizing Truthful Language Models via Peer Elicitation Games

NeurIPS 2025poster

Large Language Models (LLMs) have demonstrated strong generative capabilities but remain prone to inconsistencies and hallucinations. We introduce Peer Elicitation Games (PEG), a training-free, game-theoretic framework for aligning LLMs through a peer elicitation mechanism involving a generator and…

NesTools: A Dataset for Evaluating Nested Tool Learning Abilities of Large Language Models

COLING 2025main

Large language models (LLMs) combined with tool learning have gained impressive results in real-world applications. During tool learning, LLMs may call multiple tools in nested orders, where the latter tool call may take the former response as its input parameters. However, current research on the n…

UAQFact: Evaluating Factual Knowledge Utilization of LLMs on Unanswerable Questions

ACL 2025finding

Handling unanswerable questions (UAQ) is crucial for LLMs, as it helps prevent misleading responses in complex situations. While previous studies have built several datasets to assess LLMs’ performance on UAQ, these datasets lack factual knowledge support, which limits the evaluation of LLMs’ abilit…

$\texttt{ConflictBank}$: A Benchmark for Evaluating the Influence of Knowledge Conflicts in LLMs

NeurIPS 2024poster

Large language models (LLMs) have achieved impressive advancements across numerous disciplines, yet the critical issue of knowledge conflicts, a major source of hallucinations, has rarely been studied. While a few research explored the conflicts between the inherent knowledge of LLMs and the retriev…

LLaMA-MoE: Building Mixture-of-Experts from LLaMA with Continual Pre-Training

EMNLP 2024main

Mixture-of-Experts (MoE) has gained increasing popularity as a promising framework for scaling up large language models (LLMs). However, training MoE from scratch in a large-scale setting still suffers from data-hungry and instability problems. Motivated by this limit, we investigate building MoE mo…

MoPE: Mixture of Prefix Experts for Zero-Shot Dialogue State Tracking

COLING 2024main

Zero-shot dialogue state tracking (DST) transfers knowledge to unseen domains, reducing the cost of annotating new datasets. Previous zero-shot DST models mainly suffer from domain transferring and partial prediction problems. To address these challenges, we propose Mixture of Prefix Experts (MoPE)…

On the Logic of Theory Change Iteration of KM-Update, Revised

IJCAI 2024poster

Belief revision and update, two significant types of belief change, both focus on how an agent modifies her beliefs in presence of new information. The most striking difference between them is that the former studies the change of beliefs in a static world while the latter concentrates on a dynamica…
