HiMe: Hierarchical Embodied Memory for Long-Horizon Vision-Language-Action Control

ICML 2026poster

Current Vision-Language-Action (VLA) models excel at robotic manipulation but often struggle with non-Markovian tasks requiring long-term memory and reasoning due to their reliance on immediate observations. Existing solutions face a frequency-competence paradox, where high-performance models are to…

Learning to Move Before Learning to Do: Task-Agnostic pretraining for VLAs

ICML 2026poster

Vision-Language-Action (VLA) models are bottlenecked by the scarcity of expert demonstrations—expensive triplets of observations, language instructions, and actions. We propose that learning ''how to move'' can be decoupled from learning ''what to do,'' and that the former requires no task labels at…

SRPO: Self-Referential Policy Optimization for Vision-Language-Action Models

CVPR 2026

Vision-Language-Action (VLA) models excel in robotic manipulation but are constrained by their heavy reliance on expert demonstrations, leading to demonstration bias and limiting performance. Reinforcement learning (RL) is a vital post-training strategy to overcome these limits, yet current VLA-RL m

Speech-Audio Compositional Attacks on Multimodal LLMs and Their Defense with SALMONN-Guard

ICML 2026poster

Recent progress in large language models (LLMs) has enabled understanding of both speech and non-speech audio, but has also exposed new safety risks arising from complex audio inputs that are inadequately handled by current safeguards. We introduce SACRED-Bench (Speech–Audio Composition for RED-team…

Audio Large Language Models Can Be Descriptive Speech Quality Evaluators

ICLR 2025poster

An ideal multimodal agent should be aware of the quality of its input modalities. Recent advances have enabled large language models (LLMs) to incorporate auditory systems for handling various speech-related tasks. However, most audio LLMs remain unaware of the quality of the speech they process. Th…

ConvSearch-R1: Enhancing Query Reformulation for Conversational Search with Reasoning via Reinforcement Learning

EMNLP 2025

Conversational search systems require effective handling of context-dependent queries that often contain ambiguity, omission, and coreference. Conversational Query Reformulation (CQR) addresses this challenge by transforming these queries into self-contained forms suitable for off-the-shelf retrieve

Enabling Auditory Large Language Models for Automatic Speech Quality Evaluation

ICASSP 2025accepted

Speech quality assessment typically requires evaluating audio from multiple aspects, such as mean opinion score (MOS) and speaker similarity (SIM) etc., which can be challenging to cover using one small model designed for a single task. In this paper, we propose leveraging recently introduced audito…

A Soft Contrastive Learning-Based Prompt Model for Few-Shot Sentiment Analysis

ICASSP 2024accepted

Few-shot text classification has attracted great interest in both academia and industry due to the lack of labeled data in many fields. Different from general text classification (e.g., topic classification), few-shot sentiment classification is more challenging because the semantic distances among…

Bayesian Example Selection Improves In-Context Learning for Speech, Text and Visual Modalities

EMNLP 2024main

Large language models (LLMs) can adapt to new tasks through in-context learning (ICL) based on a few examples presented in dialogue history without any model parameter update. Despite such convenience, the performance of ICL heavily depends on the quality of the in-context examples presented, which…

Domain Generalization via Causal Adjustment for Cross-Domain Sentiment Analysis

COLING 2024main

Domain adaption has been widely adapted for cross-domain sentiment analysis to transfer knowledge from the source domain to the target domain. Whereas, most methods are proposed under the assumption that the target (test) domain is known, making them fail to generalize well on unknown test data that…
