DPad: Efficient Diffusion Language Models with Suffix Dropout

ICLR 2026poster

Diffusion-based Large Language Models (dLLMs) parallelize text generation by framing decoding as a denoising process, but suffer from high computational overhead since they predict all future suffix tokens at each step while retaining only a small fraction. We propose $\textbf{Diffusion Scratchpad}…

IncVGGT: Incremental VGGT for Memory-Bounded Long-Range 3D Reconstruction

ICLR 2026poster

We present IncVGGT, a training-free incremental variant of VGGT that makes transformer-based 3D reconstruction feasible for long sequences in real-world applications. Vanilla VGGT relies on dense global attention, which causes memory to grow quadratically and requires excessive computation, making i…

Vision-Zero: Scalable VLM Self-Improvement via Strategic Gamified Self-Play

ICLR 2026poster

Although reinforcement learning (RL) can effectively enhance the reasoning capabilities of vision–language models (VLMs), current methods remain heavily dependent on labor-intensive datasets that require extensive manual construction and verification, leading to extremely high training costs and con…

Unsolvable Problem Detection: Robust Understanding Evaluation for Large Multimodal Models

ACL 2025long

This paper introduces a novel task to evaluate the robust understanding capability of Large Multimodal Models (LMMs), termed Unsolvable Problem Detection (UPD). Multiple-choice question answering (MCQA) is widely used to assess the understanding capability of LMMs, but it does not guarantee that LMM…

Structural Sparsification for Far-Field Speaker Recognition with Intel® Gna

ICASSP 2020accepted

Recently, deep neural networks (DNN) have been widely used in speaker recognition area. In order to achieve fast response time and high accuracy, the requirements for hardware resources increase rapidly. However, as the speaker recognition application is often implemented on mobile devices, it is ne…

Learning Efficient Sparse Structures in Speech Recognition

ICASSP 2019accepted

Recurrent neural networks (RNNs), especially long short-term memories (LSTMs) have been widely used in speech recognition and natural language processing. As the sizes of RNN models grow for better performance, the computation cost and therefore the required hardware resource increase rapidly. We pr…
