Passenger-paid seat selection is one of the important sources of ancillary revenue for airlines, and machine learning-based willingness-to-pay identification is of great practicality for airlines to accurately tap potential willing passengers. However, affected by periodic statistical errors, air passenger order data often has some problems such as high noise, high latitude, and unbalanced category. In view of this, this paper proposes a method for identifying air passengers' willingness to pay for seat selection based on improved XGBoost, which is improved and integrated from three stages: data, feature, and algorithm. The feasibility of the proposed multi-stage improved integration method is verified by real airline passenger dataset, and the experimental results show that the proposed improved method has better classification effect when compared with the classical six imbalance classification models, which provides a basis for accurate marketing of airline paid seat selection programs.
乘客付费座位选择是航空公司辅助收入的重要来源之一,基于机器学习的付费意愿识别对航空公司准确挖掘潜在的付费意愿乘客具有很大的实用性。然而,受周期性统计误差的影响,航空旅客订单数据往往存在高噪声、高纬度、类别不平衡等问题。有鉴于此,本文提出了一种基于改进XGBoost的航空乘客选座意愿识别方法,该方法从数据、特征和算法三个阶段进行了改进和集成。通过实际航空公司乘客数据集验证了所提出的多级改进集成方法的可行性,实验结果表明,与经典的六种不平衡分类模型相比,所提出的改进方法具有更好的分类效果,为航空公司付费选座计划的准确营销提供了依据。

Based on the MOEA/D algorithm framework, this paper construct an improved dual-population co-evolution MOEA/D algorithm by adopt the idea of dual-population co-evolution. The simulation test of the benchmark functions shows that the proposed dual-population co-evolution MOEA/D algorithm have significant improvements in IGD and HV indicators compare with three other comparison algorithms. Finally, the application of the LTE base station power allocation model also verifies the effectiveness of the proposed algorithm.

In recent years, multi-objective optimization algorithms, especially many-objective optimization algorithms, have developed rapidly and effectively.Among them, the algorithm based on particle swarm optimization has the characteristics of simple principle, few parameters and easy implementation. However, these algorithms still have some shortcomings, but also face the problems of falling into the local optimal solution, slow convergence speed and so on. In order to solve these problems, this paper proposes an algorithm called MUD-GMOPSO, A Many-Objective Practical Swarm Optimization based on Mixture Uniform Design and Game mechanism. In this paper, the two improved methods are combined, and the convergence speed, accuracy and robustness of the algorithm are greatly improved. In addition, the experimental results show that the algorithm has better performance than the four latest multi-objective or high-dimensional multi-objective optimization algorithms on three widely used benchmarks: DTLZ, WFG and MAF.

In order to detect corn diseases accurately and quickly and reduce the impact of corn diseases on yield and quality, this paper proposes an improved object detection network named YOLOX-Tiny, which fuses convolutional attention module (CBAM), mixup data enhancement strategy, and center IOU loss function. The detection network uses the CSPNet network model as the backbone network and adds the CBAM to the feature pyramid network (FPN) of the structure, which re-assigns the feature maps' weight of different channels to enhance the extraction of deep information from the structure. The performance evaluation and comparison results of the methods show that the improved YOLOX-Tiny object detection network can effectively detect three common corn diseases, such as cercospora grayspot, northern blight, and commonrust. Compared with the traditional neural network models (90.89% of VGG-16, 97.32% of YOLOv4-tiny, 97.85% of YOLOX-Tiny, 97.91% of ResNet-50, and 97.31% of Faster RCNN), the presented improved YOLOX-Tiny network has higher accuracy.

To improve the accuracy of image classification, a kind of improved model is proposed. The shortcut is added to GoogLeNet inception v1 and several other ways of shortcut are given, and they are GRSN1_2, GRSN1_3, GRSN1_4. Among them, the information of the input layer is directly output to each subsequent layer in the form of shortcut. The new improved model has the advantages of multi-size and small convolution kernel in the same layer in the network and the advantages of shortcut to reduce information loss. Meanwhile, as the number of inception blocks increases, the number of channels is increased to deepen the extraction of information. The GRSN, GRSN1_2, GRSN1_3, GRSN1_4, GoogLeNet, and ResNet models were compared on cifar10, cifar100, and mnist datasets. The experimental results show that the proposed model has 3.07% improved to ResNet on data set cifar10, 2.08% on data set cifar100, 17.69% improved to GoogLeNet on data set cifar10, 28.47% on data set cifar100.

Methods based on deep learning have great utility in the current field of sentiment classification. To better optimize the setting of hyper-parameters in deep learning, a hybrid learning particle swarm optimization with fuzzy logic (HLPSO-FL) is proposed in this paper. Hybrid learning strategies are divided into mainstream learning strategies and random learning strategies. The mainstream learning strategy is to define the mainstream particles in the cluster and build a scale-free network through the mainstream particles. The random learning strategy makes full use of historical information and speeds up the convergence of the algorithm. Furthermore, fuzzy logic is used to control algorithm parameters to balance algorithm exploration and exploration performance. HLPSO-FL has completed comparison experiments on benchmark functions and real sentiment classification problems respectively. The experimental results show that HLPSO-FL can effectively complete the hyperparameter optimization of sentiment classification problem in deep learning and has strong convergence.

The basic tool in the analytic hierarchy process (AHP) is the complete judgment matrix. To address the weakness of the AHP in determining weight in the comprehensive evaluation system, the particle swarm optimization (PSO)-AHP model proposed in this paper is based on the PSO in the meta-heuristic algorithm. The model was used to solve the indicator weights in the evaluation system of AI education in primary and secondary schools in Fujian Province and was compared with the genetic algorithm and war strategy optimization algorithm. From the comparison results, the PSO-AHP optimization is more effective among the three algorithms, and the indicator consistency can be improved by about 30%. They are both effective in solving the problem that once the judgment matrix is given in the AHP, the weights and indicator consistency cannot be improved. Finally, the results were tested by Friedman statistics to prove the viability of the proposed algorithm.
层次分析法的基本工具是完整的判断矩阵。针对AHP在综合评价系统中确定权重的弱点,本文在元启发式算法中的粒子群优化算法的基础上,提出了粒子群优化(PSO)-AAHP模型。将该模型用于求解福建省中小学人工智能教育评价体系中的指标权重,并与遗传算法和作战策略优化算法进行了比较。从比较结果来看,PSO-AHP优化在三种算法中更有效,指标一致性可以提高约30%。它们都有效地解决了AHP中一旦给出判断矩阵,权重和指标一致性就无法提高的问题。最后,用Friedman统计量对结果进行了检验,证明了该算法的可行性。

The model was used to solve the indicator weights in the evaluation system of AI education in primary and secondary schools in Fujian Province and was compared with the genetic algorithm and war strategy optimization algorithm. From the comparison results, the PSO-AHP optimization is more effective among the three algorithms, and the indicator consistency can be improved by about 30%. They are both effective in solving the problem that once the judgment matrix is given in the AHP, the weights and indicator consistency cannot be improved. Finally, the results were tested by Friedman statistics to prove the viability of the proposed algorithm.","PeriodicalId":43637,"journal":{"name":"International Journal of Cognitive Informatics and Natural Intelligence","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42515587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The yacht industry is one of the leading industries used to guide residents’ increase in consumption. This study analyzes the evolving spatial pattern of yacht clubs in the United States from 1900-2017, aiming to explore the developmental trajectory of yacht clubs in the United States. This study finds that: 1) Yacht clubs in the United States clustered aggregately and unevenly. The concentration of yacht clubs ranges from the northeastern part of the United States to the western and southern regions. 2) The driving factors influencing the development of yacht clubs in the United States changed along with time. The state ship and boat building industry was the main driving factors in phase I (before 1900). The state steel industry was the main driver in phase II (1900-1950). In phase III (1950-2000), state tourism GDP became the main driver, and in phase IV (2000-2017), state GDP and state ocean tourism and recreation GDP became the main factors. This study enriches the literature in the area of yacht tourism in terms of understanding the temporal-spatial pattern of yacht clubs.
游艇产业是引导居民消费增长的主导产业之一。本研究分析了1900-2017年美国游艇俱乐部的空间格局演变,旨在探索美国游艇俱乐部的发展轨迹。研究发现:1)美国的游艇俱乐部聚集性较强,分布不均。游艇俱乐部的集中范围从美国东北部到西部和南部地区。2)影响美国游艇俱乐部发展的驱动因素随着时间的变化而变化。在第一阶段(1900年以前),国家船舶和造船工业是主要的驱动因素。国有钢铁工业是第二阶段(1900-1950)的主要推动力。在第三阶段(1950-2000年),州旅游GDP成为主要驱动力,在第四阶段(2000-2017年),州GDP和州海洋旅游和休闲GDP成为主要因素。本研究丰富了游艇旅游领域的文献,对游艇俱乐部的时空格局有了更深入的了解。
