A quantum-search-based multi-classifier for image recognition

引用

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 21-31页

作者： Lu Liu Xingyu wu Lufan Zhang Chuan Wang School of Artificial Intelligence Beijing Normal University Applied Optics Beijing Area Major Laboratory Beijing Normal University

The multi-class classification of images is a pivotal challenge within the realm of image processing. As the volume of visual data continues to expand, there is a burgeoning interest in harnessing the unique capabilities of quantum computation to augment the efficiency of classification tasks. However, many existing methods for training quantum image multi-classifiers parallel classical machine learning techniques, where the requisite circuit measurements increase linearly with the volume of training data. This work introduces a novel approach for training a quantum image multi-classifier based on the quantum search algorithm. We have meticulously conducted rigorous experiments on a handwritten digit dataset, a classic benchmark in the field. The results have been meticulously compared with previous works, and the comparative analysis not only validates the efficiency of our proposed approach, requiring only O(N/b) measurements during training, but also highlights a significant quadratic speedup of the algorithm.

为了检测5株不同宿主来源产气荚膜梭菌形成生物被膜能力及其对抗菌药物的敏感性差异,首先用纸片扩散法药敏试验测定5株不同来源的产气荚膜梭菌对7种抗菌药物的敏感性;筛选高敏药物测定各菌株的最小抑菌浓度(MIC);利用结晶紫染色法检测不同来源产气荚膜梭菌生物被膜形成能力和高敏药物对生物被膜的抑制和清除能力。药敏结果显示,5株不同宿主来源产气荚膜梭菌均对氨苄西林高度敏感,对其余6种抗菌药物有不同程度耐药;氨苄西林对不同菌株的MIC值在0.031~2.000μg/mL之间;所有菌株均能生成生物被膜,但生物被膜生成能力有差异;不同菌株在各自4、2、1 MIC下生物被膜的生成受到不同程度抑制,而亚抑菌浓度的氨苄西林能刺激生物被膜的生成,氨苄西林对已经生成的生物被膜不能完全清除。结果表明,不同来源产气荚膜梭菌形成生物被膜前后对药物敏感性不同,可为产气荚膜梭菌的临床用药选择及使用剂量提供一定的参考依据。
