Cancer is a group of diseases caused by abnormal cell growth, eventually leading to death. Cancer symptoms include chronic cough, breathing difficulties, weight loss, muscle stiffness, oedema, and bruises. Cancer detection increases with the stages, but unfortunately, the fatality also increases. In this research, we propose a pipeline coined as PiXelNet, which uses a classification system based on Convolutional Neural Networks (CNNs) that identifies three distinct kinds of lung cancer on histopathological images. The first step of the proposed network consists of a medical imaging analysis pipeline with models like ResNet, Efficient NetBO and MobileNet. We found that EfficientNet outperforms the other two models with a test accuracy of 99.33% and a loss of 0.0066. The second stage involves identifying the key areas from the original input test image with the feature extracted values. Using this strategy, the doctor or pathologist will immediately access all the crucial imaging heat maps and the network analysis report.
癌症是由细胞异常生长引起的一组疾病,最终导致死亡。癌症的症状包括慢性咳嗽、呼吸困难、体重减轻、肌肉僵硬、水肿和瘀伤。癌症的检出率随着分期的增加而增加,但不幸的是,死亡率也在增加。在这项研究中,我们提出了一个称为PiXelNet的管道,它使用基于卷积神经网络(cnn)的分类系统,在组织病理学图像上识别三种不同类型的肺癌。该网络的第一步包括一个医学成像分析管道,包括ResNet、Efficient NetBO和MobileNet等模型。我们发现,EfficientNet的测试准确率为99.33%,损失为0.0066,优于其他两个模型。第二阶段涉及到用特征提取值识别原始输入测试图像中的关键区域。使用这种策略,医生或病理学家将立即访问所有关键的成像热图和网络分析报告。

We propose a prototype- and metric-based prediction method together with several training pipelines suitable for training a network without using any additional data in the few-shot learning tasks with different intra-class variances. Being tested on two datasets commonly used for few-shot learning, our method has shown satisfactory ability to improve data efficiency and prevent overfitting. It even competes with the meta-learning-based method trained with a lot of extra labeled samples on the dataset with low intra-class variance and shows no significant performance gap when it comes to the dataset with a high intra-class variance. We reported 99.0% acc on the Omniglot dataset and 48.0% acc on the mini-ImageNet for 5-way 5-shot tasks.
我们提出了一种基于原型和度量的预测方法,以及几种适合训练网络的训练管道,而无需在具有不同类内方差的少量学习任务中使用任何额外数据。通过对两组常用的few-shot学习数据集的测试,我们的方法显示出了令人满意的提高数据效率和防止过拟合的能力。它甚至可以与基于元学习的方法竞争,该方法在类内方差低的数据集上训练了大量额外的标记样本,并且在类内方差高的数据集上没有明显的性能差距。我们在Omniglot数据集上报告了99.0%的acc,在mini-ImageNet上报告了48.0%的acc。

Evolutionary strategy is increasingly used for optimization in various machine learning problems. It can scale very well, even to high dimensional problems, and its ability to globally self optimize in flexible ways provides new and exciting opportunities when combined with more recent machine learning methods. This paper describes a novel approach for the optimization of models with a data driven evolutionary strategy. The optimization can directly be applied as a preprocessing step and is therefore independent of the machine learning algorithm used. The experimental analysis of six different use cases show that, on average, better results are attained than without evolutionary strategy. Furthermore it is shown, that the best individual models are also achieved with the help of evolutionary strategy. The six different use cases were of different complexity which reinforces the idea that the approach is universal and not depending on specific use cases.
进化策略越来越多地用于各种机器学习问题的优化。它可以很好地扩展,甚至是高维问题,它以灵活的方式进行全局自我优化的能力,与最新的机器学习方法相结合,提供了新的、令人兴奋的机会。本文描述了一种基于数据驱动进化策略的模型优化新方法。优化可以直接应用于预处理步骤,因此独立于所使用的机器学习算法。对六个不同用例的实验分析表明,平均而言,获得比没有进化策略更好的结果。此外,在进化策略的帮助下,也可以获得最佳的个体模型。六个不同的用例具有不同的复杂性,这加强了该方法是通用的,而不依赖于特定用例的想法。

Recently, Machine Learning (ML) methods are built-in as an important component in many smart agriculture platforms. In this paper, we explore the new combination of advanced ML methods for creating a smart agriculture platform where farmers could reach out for assistance from the public, or a closed circle of experts. Specifically, we focus on an easy way to assist the farmers in understanding plant diseases where the farmers can get help to solve the issues from the members of the community. The proposed system utilizes deep learning techniques for identifying the disease of the plant from the affected image, which acts as an initial identifier. Further, Natural Language Processing techniques are employed for ranking the solutions posted by the user community. In this paper, a message channel is built on top of Twitter, a popular social media platform to establish proper communication among farmers. Since the effect of the solutions can differ based on various other parameters, we extend the use of the concept drift approach and come up with a good solution and propose it to the farmer. We tested the proposed framework on the benchmark dataset, and it produces accurate and reliable results.
最近,机器学习(ML)方法作为一个重要组成部分被内置在许多智能农业平台中。在本文中,我们探索了先进的机器学习方法的新组合,以创建一个智能农业平台,农民可以向公众或封闭的专家圈子寻求帮助。具体来说,我们专注于一个简单的方法来帮助农民了解植物病害,农民可以从社区成员那里得到帮助来解决问题。该系统利用深度学习技术从受影响的图像中识别植物的疾病,该图像作为初始标识符。此外,使用自然语言处理技术对用户社区发布的解决方案进行排名。本文在流行的社交媒体平台Twitter上建立了一个消息通道,以建立农民之间的适当沟通。由于解决方案的效果可能会因各种其他参数而有所不同,因此我们扩展了概念漂移方法的使用,并提出了一个很好的解决方案,并将其推荐给农民。我们在基准数据集上对所提出的框架进行了测试,得到了准确可靠的结果。

Rough Set Model and Approximations in Fuzzy Formal Contexts 模糊形式环境下的粗糙集模型与近似
Pub Date : 2022-12-01 DOI: 10.1109/ACMLC58173.2022.00018
Yu-Ru Syau, E. Lin
Given a set of objects G with a set of attributes M and a binary relation I, a formal context (G, M, I) corresponds to a Boolean-valued information table in rough set theory, and the kernel relation of the function from G to M which maps each object of G to its afterset. This coincides with the indiscernibility relation of the Boolean-valued information table. Rough set model and Variable-Precision model (VP-model) under a formal context can be formulated based on the associated kernel relation on the objects set. $alpha$-fuzzified rough set model and VP-model under a fuzzy formal context are formulated analogously. We present an example to demonstrate the proposed $alpha$-fuzzified rough set model and VP-model under a fuzzy formal context.
给定一组具有属性M的对象G和一个二元关系I,一个形式上下文(G, M, I)对应于粗糙集理论中的布尔值信息表,以及从G到M的函数的核关系,该函数将G的每个对象映射到它的后集。这与布尔值信息表的不可分辨关系是一致的。基于对象集上的关联核关系,可以建立形式上下文下的粗糙集模型和变精度模型。将$alpha$-模糊粗糙集模型和模糊形式环境下的vp -模型类比地表述出来。我们给出了一个例子来证明在模糊形式环境下提出的$alpha$-模糊粗糙集模型和vp -模型。

A Data-Driven Pricing Strategy for Automobile Insurance Policies 汽车保险政策的数据驱动定价策略
Pub Date : 2022-12-01 DOI: 10.1109/ACMLC58173.2022.00009
Patrick Hosein
An automobile insurance policy premium depends on three factors, the risk associated with the drivers and cars on the policy, the operational costs to manage the policy and the profit margin. The premium is then some function of these. Operational costs are dependent on the company efficiency. The achieved profit margin is dependent on the competition experienced. Risk, however, is a customer dependent factor and hence premiums should take into account potential risk of a new policy. Traditionally, risk tables are used to compute the risk of a new customer but we instead use historical data to predict the average claim amount that would be made on a new policy in the coming year if it was approved. We use this value, as a measure of risk, to better determine the premium that is charged. We illustrate the approach with a single customer feature, the age of the driver, but the approach can be used to take into account several customer and/or car features.
汽车保险单的保费取决于三个因素,与保险单上的司机和汽车相关的风险,管理保险单的运营成本和利润率。溢价是这些的函数。运营成本取决于公司的效率。实现的利润率取决于所经历的竞争。然而,风险是客户所依赖的因素,因此保费应考虑到新保单的潜在风险。传统上,风险表用于计算新客户的风险,但我们使用历史数据来预测新保单如果获得批准,在来年将获得的平均索赔金额。我们用这个值来衡量风险,以便更好地确定要收取的保费。我们使用单个客户特征(驾驶员的年龄)来说明该方法,但该方法可用于考虑多个客户和/或汽车特征。

Research shows that high turnover rate will inevitably damage the sustainable and healthy development of the enterprise. Thanks to the rapid development of artificial intelligence technology, it is possible to build a model to predict employee turnover intension by analyzing employee turnover data. This study uses employee data of a company on the Kaggle platform, proposes an oversampling method for predicting employee turnover in view of data imbalance in the data set. Four models Gaussian NB, support vector machine for classification (SVC), K-Nearest Neighbor (KNN) and Gradient Boosting were established and trained to analyze the employee turnover features and predict the occurrence of employee turnover events.

Travel planning is an important part of tourism. Unlike traditional experience journeys, these journeys developed using mathematical modeling techniques are more scientifically reliable. The mathematical model of travel planning problem is based on tourism marketing problem, which can be solved by ant trap algorithm. At the same time, the development of information technology has led to the transformation of tourism travel organization from the traditional experience based design to a higher level. In this work, this paper focuses on the use of advanced ant algorithm to solve the travel booking problem, self-guided route planning problem and intelligent route planning problem. First, this paper proposes an advanced solution to the ACO based travel assignment problem. In order to realize the ant trap algorithm to solve the travel route problem, when solving the travel quota problem, the ant trap algorithm should obtain the optimal solution with high probability, and the solution time of the algorithm should be relatively short. Secondly, this paper improves the path selection probability and pheromone updating rules, locally searches the optimal path, optimizes the algorithm solving process, and determines the logic parameters of the algorithm. Through performance simulation analysis, the algorithm proposed in this work solves the line problem, with high search accuracy and short solution time.
旅游规划是旅游业的重要组成部分。与传统的体验旅程不同,这些使用数学建模技术开发的旅程在科学上更可靠。旅游规划问题的数学模型是基于旅游营销问题,可以用蚁群陷阱算法求解。同时,信息技术的发展使得旅游组织从传统的基于体验的设计向更高层次的转变。在本工作中,本文重点研究了利用先进的蚂蚁算法解决出行预订问题、自引导路线规划问题和智能路线规划问题。首先,对基于蚁群算法的出行分配问题提出了一种改进的解决方案。为了实现蚂蚁陷阱算法解决出行路线问题,在求解出行配额问题时,蚂蚁陷阱算法应以高概率获得最优解,且算法的求解时间应相对较短。其次,改进路径选择概率和信息素更新规则,局部搜索最优路径,优化算法求解过程,确定算法的逻辑参数;通过性能仿真分析,本文提出的算法解决了直线问题,具有搜索精度高、求解时间短的特点。
