A Novel Image Classification Framework Based on Variational Quantum Algorithms

no code implementations13 Dec 2023 Yixiong Chen

To overcome this limitation, we introduce a novel image classification framework that leverages variational quantum algorithms (VQAs)-hybrid approaches combining quantum and classical computing paradigms within quantum machine learning.

Human Preference Score v2: A Solid Benchmark for Evaluating Human Preferences of Text-to-Image Synthesis

1 code implementation15 Jun 2023 Xiaoshi Wu, Yiming Hao, Keqiang Sun, Yixiong Chen, Feng Zhu, Rui Zhao, Hongsheng Li

By fine-tuning CLIP on HPD v2, we obtain Human Preference Score v2 (HPS v2), a scoring model that can more accurately predict human preferences on generated images.

When Person Re-identification Meets Changing Clothes

no code implementations9 Mar 2020 Fangbin Wan, Yang Wu, Xuelin Qian, Yixiong Chen, Yanwei Fu

We find that changing clothes makes ReID a much harder problem in the sense of bringing difficulties to learning effective representations and also challenges the generalization ability of previous ReID models to identify persons with unseen (new) clothes.
