IVC-Prune: Revealing the Implicit Visual Coordinates in LVLMs for Vision Token Pruning

ICLR 2026poster

Large Vision-Language Models (LVLMs) achieve impressive performance across multiple tasks. A significant challenge, however, is their prohibitive inference cost when processing high-resolution visual inputs. While visual token pruning has emerged as a promising solution, existing methods that primar…

MHA2MLA-VLM: Enabling DeepSeek’s Economical Multi-Head Latent Attention Across Vision-Language Models

AAAI 2026technical

As vision-language models (VLMs) tackle increasingly complex and multimodal tasks, the rapid growth of Key-Value (KV) cache imposes significant memory and computational bottlenecks during inference. While Multi-Head Latent Attention (MLA) offers an effective means to compress the KV cache and accele

What Makes a Good Speech Tokenizer for LLM-Centric Speech Generation? A Systematic Study

AAAI 2026technical

Speech-language models (SLMs) offer a promising path toward unifying speech and text understanding and generation. However, challenges remain in achieving effective cross-modal alignment and high-quality speech generation. In this work, we systematically investigate the role of speech tokenizer desi

CQ-DINO: Mitigating Gradient Dilution via Category Queries for Vast Vocabulary Object Detection

NeurIPS 2025poster

With the exponential growth of data, traditional object detection methods are increasingly struggling to handle vast vocabulary object detection tasks effectively. We analyze two key limitations of classification-based detectors: positive gradient dilution, where rare positive categories receive ins…

Shifted Autoencoders for Point Annotation Restoration in Object Counting

ECCV 2024poster

"Object counting typically uses 2D point annotations. The complexity of object shapes and the subjectivity of annotators may lead to annotation inconsistency, potentially confusing counting model training. Some sophisticated noise-resistance counting methods have been proposed to alleviate this issu…
