DRFGD: Disentangled Representation-Focused Generative Defense for Attack-Tolerant Cross-Modal Hashing

AAAI 2026technical

With the widespread deployment of cross-modal retrieval in real-world scenarios, ensuring robustness against adversarial attacks is increasingly critical. Remarkably, deep cross-modal hashing is highly vulnerable to adversarial attacks due to its discrete nature and low-dimensional hash codes, while

InTrain: Intrinsic Trainability for Zero-Cost Neural Architecture Search

CVPR 2026

Training-free neural architecture search promises efficient discovery of high-performance networks without costly training. However, existing zero-cost proxies rely on fragmented heuristics that fail to capture the fundamental question: what makes an architecture trainable? This paper introduces Int

Component-Level Segmentation for Oracle Bone Inscription Decipherment

AAAI 2025technical

Oracle Bone Inscriptions (OBIs), as the earliest systematically organized pictographic script in China, hold significant importance in the study of the origins of Chinese civilization. Of the approximately 4,500 excavated OBI characters, only about one-third have been deciphered, leaving the remaini…

Feature Fusion from Head to Tail for Long-Tailed Visual Recognition

AAAI 2024technical

The imbalanced distribution of long-tailed data presents a considerable challenge for deep learning models, as it causes them to prioritize the accurate classification of head classes but largely disregard tail classes. The biased decision boundary caused by inadequate semantic information in tail c…

Key Points Centered Sparse Hashing for Cross-Modal Retrieval

ICASSP 2024accepted

Supervised cross-modal hashing methods usually construct a massive undirected weighted graph based on labels for training data, with the aim of learning more structured hash codes by preserving relationships within this graph. However, as the volume of data increases, such an approach demands substa…
