HierAmp: Coarse-to-Fine Autoregressive Amplification for Generative Dataset Distillation

CVPR 2026

Dataset distillation often prioritizes global semantic proximity when creating small surrogate datasets for original large-scale ones. However, object semantics are inherently hierarchical. For example, the position and appearance of a bird's eyes are constrained by the outline of its head. Global p

A Novel Part Feature Integration and Fusion Method for Fine-Grained Vehicle Recognition

ICASSP 2022accepted

In this paper, we propose a novel light-weight feature integration and fusion method to enhance the discriminative ability of deep convolutional features for the task of fine-grained vehicle recognition. The proposed method is built on the deep convolutional layers from which the discriminative part…
