Beyond Geometry: Artistic Disparity Synthesis for Immersive 2D-to-3D

CVPR 2026

Current 2D-to-3D conversion methods achieve geometric accuracy but are artistically deficient, failing to replicate the immersive and emotionally resonant experience of professional 3D cinema. This is because "geometric reconstruction" paradigms mistake deliberate artistic intent--such as strategic

Beyond Real: Imaginary Extension of Rotary Position Embeddings for Long-Context LLMs

ICLR 2026poster

Rotary Position Embeddings (RoPE) have become a standard for encoding sequence order in Large Language Models (LLMs) by applying rotations to query and key vectors in the complex plane. Standard implementations, however, utilize only the real component of the complex-valued dot product for attention…

GlitchMiner: Mining Glitch Tokens in Large Language Models via Gradient-based Discrete Optimization

AAAI 2026technical

Glitch tokens—inputs that trigger unpredictable or anomalous behavior in Large Language Models (LLMs)—pose significant challenges to model reliability and safety. Existing detection methods primarily rely on heuristic embedding patterns or statistical anomalies within internal representations, limit

HiMo-CLIP: Modeling Semantic Hierarchy and Monotonicity in Vision-Language Alignment

AAAI 2026technical

Contrastive vision-language models like CLIP have achieved impressive results in image-text retrieval by aligning image and text representations in a shared embedding space. However, these models often treat text as flat sequences, limiting their ability to handle complex, compositional, and long-fo

MeanCache: From Instantaneous to Average Velocity for Accelerating Flow Matching Inference

ICLR 2026poster

We present MeanCache, a training-free caching framework for efficient Flow Matching inference. Existing caching methods reduce redundant computation but typically rely on instantaneous velocity information (e.g., feature caching), which often leads to severe trajectory deviations and error accumulat…

Sparser Block-Sparse Attention via Token Permutation

ICML 2026poster

Scaling the context length of large language models (LLMs) offers significant benefits but is computationally expensive. This expense stems primarily from the self-attention mechanism, whose $O(N^2)$ complexity with respect to sequence length presents a major bottleneck for both memory and latency. …

Fuzzy Reasoning Chain (FRC): An Innovative Reasoning Framework from Fuzziness to Clarity

EMNLP 2025

With the rapid advancement of large language models (LLMs), natural language processing (NLP) has achieved remarkable progress. Nonetheless, significant challenges remain in handling texts with ambiguity, polysemy, or uncertainty. We introduce the Fuzzy Reasoning Chain (FRC) framework, which integra

LeMiCa: Lexicographic Minimax Path Caching for Efficient Diffusion-Based Video Generation

NeurIPS 2025spotlight

We present LeMiCa, a training-free and efficient acceleration framework for diffusion-based video generation. While existing caching strategies primarily focus on reducing local heuristic errors, they often overlook the accumulation of global errors, leading to noticeable content degradation between…

Optimizing for the Shortest Path in Denoising Diffusion Model

CVPR 2025highlight

In this research, we propose a novel denoising diffusion model based on shortest-path modeling that optimizes residual propagation to enhance both denoising efficiency and quality. Drawing on Denoising Diffusion Implicit Models (DDIM) and insights from graph theory, our model, termed the Shortest Pa…

A Unified Framework for Mutual Improvement of SLAM and Semantic Segmentation

ICRA 2019poster

This paper presents a novel framework for simultaneously implementing localization and segmentation, which are two of the most important vision-based tasks for robotics. While the goals and techniques used for them were considered to be different previously, we show that by making use of the interme…
