A dandelion algorithm(DA) is a recently developed intelligent optimization algorithm for function optimization problems. Many of its parameters need to be set by experience in DA,which might not be appropriate for all optimization problems. A self-adapting and efficient dandelion algorithm is proposed in this work to lower the number of DA's parameters and simplify DA's structure. Only the normal sowing operator is retained;while the other operators are discarded. An adaptive seeding radius strategy is designed for the core dandelion. The results show that the proposed algorithm achieves better performance on the standard test functions with less time consumption than its competitive peers. In addition, the proposed algorithm is applied to feature selection for credit card fraud detection(CCFD), and the results indicate that it can obtain higher classification and detection performance than the-state-of-the-art methods.

Personalized trajectory data perturbation algorithm based on quadtree indexing

引用

The Journal of China Universities of Posts and Telecommunications 2024年

作者： Liu Kun Jin Junhui Wang Hui Shen Zihao Liu Peiqian School of Software Henan Polytechnic university School of Computer Science and Technology Henan Polytechnic university

To solve the privacy leakage problem of truck trajectories in intelligent logistics， this paper proposes a quadtree-based personalized joint location perturbation (QPJLP) algorithm using location generalization and local differential privacy (LDP) techniques. Firstly， a flexible position encoding mechanism based on the spatial quadtree indexing is designed， and the length of the encoding can be adjusted freely according to data availability. Secondly， to meet the privacy needs of different locations of users， location categories are introduced to classify locations as sensitive and ordinary locations. Finally， the truck invokes the corresponding mechanism in the QPJLP algorithm to locally perturb the code according to the location category， allowing the protection of non-sensitive locations to be reduced without weakening the protection of sensitive locations， thereby improving data availability. Simulation experiments demonstrate that the proposed algorithm effectively meets the personalized trajectory privacy requirements while also exhibiting good performance in trajectory proportion estimation and Top-K classification.

Changes in physicochemical characteristics of wheat flour and quality of fresh wet noodles induced by microwave treatment

引用

Grain & Oil Science and Technology 2024年第3期7卷 177-185页

作者： Jian Zhang Xuejie Li Xiujuan Ren Yanxia An Xiaoyan Song Yang Zhao Yaqing Wen Weifeng Zhang College of Food Science and Technology Henan Agricultural University School of Food Science and Engineering Zhengzhou University of Science and Technology

Fresh wet noodles(FWN) are popular staple foods due to its unique chewy texture and favorable taste. However,the development of FWN is limited by its short shelf life and high browning rate. It has been found that the quantity of original microorganisms in wheat flour produced by traditional method is relatively high, which is detrimental to the processing quality and storage stability of FWN. Consequently, it becomes imperative to decrease microorganisms in wheat flour. Microwave treatment has been regarded as a promising method in the food industry due to its potential in inhibiting microbial growth and inactivating enzymes without causing adverse effect on the food quality. This study aims to investigate the effects of microwave treatment of wheat kernels under different powers(1, 2, 3, 4, 5 kW) on the physicochemical properties of wheat flour and the quality of FWN. The results revealed that microwave treatment had a significant effect on microbial inhibition and enzyme inactivation, wherein the total plate count(TPC) and yeast and mold counts(YMC) decreased by 0.87 lg(CFU/g) and 1.13 lg(CFU/g) respectively, and PPO activity decreased from 11.40 U to 6.31 U. The dough quality properties, such as stability, extensibility, and starch viscosity, improved significantly under different microwave conditions. Confocal laser scanning microscopy(CLSM) images indicated that starch and proteins aggregated gradually in treated flour, altering rheological properties of dough. From the results of scanning electron microscopy(SEM), microwave treatment led to the appearance of disrupted structure in the gluten proteins, but the secondary structure of proteins altered slightly. Rheological properties of dough confirmed that the microwave treatment greatly affected processing characteristics of wheat flour products, with significant advantageous consequences on product quality, especially for textural properties of FWN. Furthermore, FWN darkening could be inhibited noticeably aft
