CrossHash: Cross-scale Vision Transformer Hashing for Image Retrieval

ICASSP 2025accepted

Transformers have made significant progress in dealing with computer vision tasks. However, most existing Vision Transformers (ViT) typically focus on single-scale information, limiting their capability to model interactions when processing multi-scale features. Moreover, the explicit mapping of con…

Geometric-Facilitated Denoising Diffusion Model for 3D Molecule Generation

AAAI 2024technical

Denoising diffusion models have shown great potential in multiple research areas. Existing diffusion-based generative methods on de novo 3D molecule generation face two major challenges. Since majority heavy atoms in molecules allow connections to multiple atoms through single bonds, solely using pa…

Joint-Semantics Multi-Similarity Hashing for Cross-Modal Retrieval

ICASSP 2024accepted

Recently, cross-modal hashing has attracted much attention in large-scale image retrieval scenarios. However, most existing methods ignore the potential higher-order relationships and label semantic information between heterogeneous modality data. Besides, the imbalanced training samples could bias…

Pyramid: A Heterogeneous Data Integration Algorithm Based on Hierarchical Graph

ICASSP 2024accepted

The surging volume of big data underscores the imperative of integrating heterogeneous datasets into a unified, semantically consistent format. We introduce Pyramid, a comprehensive framework for heterogeneous data integration, addressing schema transformation, feature encoding, entity matching, ded…
