An Empirical Study on How Video-LLMs Answer Video Questions

CVPR 2026

Taking advantage of large-scale data and pretrained language models, Video Large Language Models (Video-LLMs) have shown strong capabilities in answering video questions. However, most existing efforts focus on improving performance, with limited attention to understanding their internal mechanisms.

MCIE: Multimodal LLM-Driven Complex Instruction Image Editing with Spatial Guidance

AAAI 2026technical

Recent advances in instruction-based image editing have shown remarkable progress. However, existing methods remain limited to relatively simple editing operations, hindering real-world applications that require complex and compositional instructions. In this work, we address these limitations from

OmniSparse: Training-Aware Fine-Grained Sparse Attention for Long-Video MLLMs

AAAI 2026technical

Existing sparse attention methods primarily target inference-time acceleration by selecting critical tokens under predefined sparsity patterns. However, they often fail to bridge the training–inference gap and lack the capacity for fine-grained token selection across multiple dimensions—such as quer

FPSAttention: Training-Aware FP8 and Sparsity Co-Design for Fast Video Diffusion

NeurIPS 2025spotlight

Diffusion generative models have become the standard for producing high-quality, coherent video content, yet their slow inference speeds and high computational demands hinder practical deployment. Although both quantization and sparsity can independently accelerate inference while maintaining genera…

ZPressor: Bottleneck-Aware Compression for Scalable Feed-Forward 3DGS

NeurIPS 2025poster

Feed-forward 3D Gaussian Splatting (3DGS) models have recently emerged as a promising solution for novel view synthesis, enabling one-pass inference without the need for per-scene 3DGS optimization. However, their scalability is fundamentally constrained by the limited capacity of their encoders, le…

MiniCache: KV Cache Compression in Depth Dimension for Large Language Models

NeurIPS 2024poster

A critical approach for efficiently deploying computationally demanding large language models (LLMs) is Key-Value (KV) caching. The KV cache stores key-value states of previously generated tokens, significantly reducing the need for repetitive computations and thereby lowering latency in autoregress…
