EMOTION-ALIGNED GENERATION IN DIFFUSION TEXT TO SPEECH MODELS VIA PREFERENCE-GUIDED OPTIMIZATION

ICASSP 2026oral

Emotional text-to-speech seeks to convey affect while preserving intelligibility and prosody, yet existing methods rely on coarse labels or proxy classifiers and receive only utterance-level feedback. We introduce Emotion-Aware Stepwise Preference Optimization (EASPO), a post-training framework that…

FINSENTLLM: MULTI-LLM AND STRUCTURED SEMANTIC SIGNALS FOR ENHANCED FINANCIAL SENTIMENT FORECASTING

ICASSP 2026poster

Financial sentiment analysis (FSA) has attracted significant attention, and recent studies increasingly explore large language models (LLMs) for this field. Yet most work evaluates only classification metrics, leaving unclear whether sentiment signals align with market behavior. We propose FinSentLL…

ShieldedCode: Learning Robust Representations for Virtual Machine Protected Code

ICLR 2026poster

Large language models (LLMs) have achieved remarkable progress in code generation, yet their potential for software protection remains largely untapped. Reverse engineering continues to threaten software security, while traditional virtual machine protection (VMP) relies on rigid, rule-based tran…

ViG-RAG: Video-aware Graph Retrieval-Augmented Generation via Temporal and Semantic Hybrid Reasoning

AAAI 2026technical

Retrieval-augmented generation (RAG) has greatly improved Large Language Models (LLMs) by adding external knowledge. However, current RAG-based methods face difficulties with long-context video understanding due to two main challenges. First, Current RAG-based methods for long-context video understa

dMLLM-TTS: Self-Verified and Efficient Test-Time Scaling for Diffusion Multi-Modal Large Language Models

CVPR 2026

Diffusion Multi-modal Large Language Models (dMLLMs) have recently emerged as a novel architecture unifying image generation and understanding. However, developing effective and efficient Test-Time Scaling (TTS) methods to unlock their full generative potential remains an underexplored challenge. To

ArtFormer: Controllable Generation of Diverse 3D Articulated Objects

CVPR 2025poster

This paper presents a novel framework for modeling and conditional generation of 3D articulated objects. Troubled by flexibility-quality tradeoffs, existing methods are often limited to using predefined structures or retrieving shapes from static datasets. To address these challenges, we parameteriz…

DocAgent: An Agentic Framework for Multi-Modal Long-Context Document Understanding

EMNLP 2025

Recent advances in large language models (LLMs) have demonstrated significant promise in document understanding and question-answering. Despite the progress, existing approaches can only process short documents due to limited context length or fail to fully leverage multi-modal information. In this

GLIMPSE: Do Large Vision-Language Models Truly Think With Videos or Just Glimpse at Them?

EMNLP 2025

Existing video benchmarks often resemble image-based benchmarks, with question types like “What actions does the person perform throughout the video?” or “What color is the woman’s dress in the video?” For these, models can often answer by scanning just a few key frames, without deep temporal reason

MaRI: Material Retrieval Integration across Domains

CVPR 2025poster

Accurate material retrieval is critical for creating realistic 3D assets. Existing methods rely on datasets that capture shape-invariant and lighting-varied representations of materials, which are scarce and face challenges due to limited diversity and inadequate real-world generalization. Most curr…

ReAgent-V: A Reward-Driven Multi-Agent Framework for Video Understanding

NeurIPS 2025poster

Video understanding is fundamental to tasks such as action recognition, video reasoning, and robotic control. Early video understanding methods based on large vision-language models (LVLMs) typically adopt a single-pass reasoning paradigm without dynamic feedback, limiting the model’s capacity to se…

SRPO: Enhancing Multimodal LLM Reasoning via Reflection-Aware Reinforcement Learning

NeurIPS 2025poster

Multimodal large language models (MLLMs) have shown promising capabilities in reasoning tasks, yet still struggle significantly with complex problems requiring explicit self-reflection and self-correction, especially compared to their unimodal text-based counterparts. Existing reflection methods are…

TRiCo: Triadic Game-Theoretic Co-Training for Robust Semi-Supervised Learning

NeurIPS 2025poster

We introduce TRiCo, a novel triadic game-theoretic co-training framework that rethinks the structure of semi-supervised learning by incorporating a teacher, two students, and an adversarial generator into a unified training paradigm. Unlike existing co-training or teacher-student approaches, TRiCo f…

Wcdt: World-Centric Diffusion Transformer for Traffic Scene Generation

ICRA 2025

In this paper, we introduce a novel approach for autonomous driving trajectory generation by harnessing the complementary strengths of diffusion probabilistic models (a.k.a., diffusion models) and transformers. Our proposed framework, termed the “World-centric Diffusion Transformer” (WcDT), optimize
