Decompose Semantic Shifts for Composed Image Retrieval

no code implementations18 Sep 2023 Xingyu Yang, Daqing Liu, Heng Zhang, Yong Luo, Chaoyue Wang, Jing Zhang

Composed image retrieval is a type of image retrieval task where the user provides a reference image as a starting point and specifies a text on how to shift from the starting point to the desired target image.

SPA: Stochastic Probability Adjustment for System Balance of Unsupervised SNNs

no code implementations19 Oct 2020 Xingyu Yang, Mingyuan Meng, Shanlin Xiao, Zhiyi Yu

Spiking neural networks (SNNs) receive widespread attention because of their low-power hardware characteristic and brain-like signal response mechanism, but currently, the performance of SNNs is still behind Artificial Neural Networks (ANNs).
