In recent years skin cancer is becoming more and more threatening because of its fast and significant spread worldwide. This evidence has increased interest and efforts in the development of automatic diagnostic computational systems to assist early diagnosis. Several approaches have been proposed to assist in skin lesion diagnosis which used machine learning and ensemble learning. In some cases, a classifier can correctly predict the output class while others fail and vice versa. So the idea is to use different machine learning and ensemble learning to classify skin cancer. In this paper, we propose an improved ensemble learning method to classify skin cancer. Features used are the best combination of extracted features from different characteristics, i.e., shape, color, texture, and skeleton of the lesion, then we classify these features using different algorithms to predict the classes. Globally, the experimented results show a promoting result.
近年来,由于皮肤癌在世界范围内的快速和显著传播,它变得越来越具有威胁性。这一证据增加了人们对开发自动诊断计算系统以协助早期诊断的兴趣和努力。已经提出了几种使用机器学习和集成学习来辅助皮肤病变诊断的方法。在某些情况下,分类器可以正确预测输出类,而其他分类器则会失败,反之亦然。所以我们的想法是使用不同的机器学习和集成学习来分类皮肤癌。在本文中,我们提出了一种改进的集成学习方法来分类皮肤癌。使用的特征是从不同特征中提取的特征的最佳组合,即病变的形状、颜色、纹理和骨骼,然后我们使用不同的算法对这些特征进行分类,以预测类别。在全球范围内,实验结果显示出令人鼓舞的效果。

Federated Learning is a distributed machine learning approach which enables model training without sharing private locally produced data. It has been actively researched for several years as a means to utilize big data while protecting personal information. However, the server must decide which clients to participate in and what results to be used for aggregation each round. Besides, since the server needs to maintain the connection with the client directly, device overload and the processing delay may cause due to changes in the system environment such as network condition. In this paper, we propose a data management system that efficiently addresses the problem of general Federated Learning by improvements of the data management process on the connection between the Federated Learning server and the client. Additionally, it is shown that the proposed system can perform tasks independently and scales for increasing number of devices participating in the Federated Learning tasks.
联邦学习是一种分布式机器学习方法,可以在不共享私有本地生成数据的情况下进行模型训练。作为一种利用大数据同时保护个人信息的手段,这几年来一直在积极研究。但是,服务器必须决定参与哪些客户机,以及每轮使用哪些结果进行聚合。此外,由于服务器需要直接与客户端保持连接,因此由于网络条件等系统环境的变化,可能会导致设备过载和处理延迟。在本文中,我们提出了一个数据管理系统,该系统通过改进联邦学习服务器和客户端之间连接的数据管理过程,有效地解决了通用联邦学习的问题。此外,研究表明,所提出的系统可以独立执行任务,并可以随着参与联邦学习任务的设备数量的增加而扩展。

In this paper, we propose a new algorithm for computing Hahn polynomial coefficients (HPCs) for higher polynomial order, which greatly reduces the spread of numerical defects associated with Hahn polynomials (HPs) using conventional methods. The proposed method is used to reconstruct large 2D images. The reliability and effectiveness of the new approach were often linked to standard repetition algorithms. The findings show that the method proposed is efficient and effective in terms of calculation accuracy and stability of high order Hahn moments.

This paper presents a new distributed polymorphic learning model for a community of heterogeneous cyber physical robots operating in a multi agent environment. This model allows a community of intelligent physical agents to exchange their minds represented by configured and trained neural net-works. The training operation of the neural networks is performed, using machines and deep learning techniques, in a distributed way based on special agents deployed in machines having high-performance computing resources based on GPUs. Each mind, specialized in a specific field, is initially affected to an agent. Depending on the event context, robots can automatically select the trained and appropriate trained network to resolve the situation either by using their own training models, or by collaborating with other agents specialized to perform the context event. In this article, we present results of a model implementation based on DeepLearning4J Framework and a multi-agent system middleware

Nowadays Data Mining is used in many application areas enabling large data streams and algorithms for analysis and extraction of powerful data. On their side, the Computer Environments for Human Learning (EIAH) offer TEL devices (Technology-enhanced learning) such as simulators, serious games, MOOCs (massive online open courses), or educational platforms. These devices provide data that are traces of the activities of students or teachers. The data produced are cognitive information of very fine levels (student knowledge, skills, and errors) and require specific analysis and processing tools, we talk here about educational data mining methods, Educational data processing (EDM) is rising as a notion of research and analysis with a set of machine and psychological ways and research approaches for understanding however students learn. EDM uses machine approaches to research instructional knowledge so as to review instructional queries. For this knowledge exploration, several tools were used like personal learning environments, recommender systems, Context learning, and Course management systems. These tools offer numerous edges for instructional data processing. In this survey, we have a tendency to focus and supply numerous tools of analysis trends exploitation EDM Tools to explore data and knowledge, and explaining the process of EDM application, the goal is not only to transform the data into knowledge but also to filter the extracted knowledge to know how to modify the educational environment to improve learners’ learning. This paper surveys the foremost relevant studies administrated during this field up to date.
如今,数据挖掘在许多应用领域都得到了应用,为分析和提取强大的数据提供了大量的数据流和算法。在他们这一边,人类学习的计算机环境(EIAH)提供TEL设备(技术增强学习),如模拟器、严肃游戏、mooc(大规模在线开放课程)或教育平台。这些设备提供的数据是学生或教师活动的痕迹。所产生的数据是非常精细的认知信息(学生的知识、技能和错误),需要特定的分析和处理工具,我们在这里讨论教育数据挖掘方法,教育数据处理(EDM)作为一种研究和分析的概念正在兴起,它采用了一套机器和心理学的方法和研究方法来理解学生的学习方式。EDM使用机器方法来研究教学知识,从而审查教学查询。对于这种知识探索,使用了几个工具,如个人学习环境,推荐系统,上下文学习和课程管理系统。这些工具为教学数据处理提供了许多优势。在本次调查中,我们倾向于集中并提供大量分析趋势的工具,利用EDM工具来探索数据和知识,并解释EDM应用的过程,目的不仅是将数据转化为知识,而且还要过滤提取的知识,以了解如何修改教育环境以提高学习者的学习。本文综述了迄今为止在这一领域进行的最重要的相关研究。

Local Ontologies Merging in Data Ponds 数据池中的本地本体合并
Pub Date : 2020-06-01 DOI: 10.1109/ISCV49265.2020.9204097
Jabrane Kachaoui, A. Belangour
Today, Ontologies have a major place in knowledge representation and modeling. They are used to formalize a domain knowledge and add a semantic layer to current systems and applications. Ontologies make it possible to explicitly represent the knowledge of a domain by means a formal language so that they can be manipulated automatically and shared easily. They are widely used in various fields of research such as Knowledge Representation (KR) and Data Integration (DI). However, the effectiveness to interoperate learning objects among various learning object repositories is often decreased because of using different ontological schemes for annotating learning objects into every learning object repository. Hence, semantic heterogeneity and structural differences between ontologies need to be resolved so as to generate common ontology to expedite learning object reusability. This paper focused on automated ontology mapping and merging concept. The study significance lies in an algorithmic approach for mapping attributes of learning objects/concepts and merging them based on mapped attributes; identifying suitable threshold value for mapping and merging.
今天,本体在知识表示和建模中占有重要地位。它们用于形式化领域知识,并为当前系统和应用程序添加语义层。本体使得通过形式语言显式地表示一个领域的知识成为可能,这样它们就可以被自动地操纵和轻松地共享。它们被广泛应用于知识表示(KR)和数据集成(DI)等各个研究领域。然而,由于使用不同的本体方案将学习对象标注到每个学习对象库中,往往会降低不同学习对象库之间互操作学习对象的有效性。因此,需要解决本体之间的语义异构性和结构差异,从而生成通用本体,加快学习对象的可重用性。本文主要研究了自动化本体映射和合并的概念。本文的研究意义在于提出了一种映射学习对象/概念属性并基于映射属性进行融合的算法方法;为映射和合并确定合适的阈值。

Quantification of soil moisture variability over agriculture fields using Sentinel imagery 利用哨兵图像对农田土壤湿度变异性进行量化

The purpose of this study is to quantify soil moisture variability in agriculture fields at field scale resolution using the Sentinel data (Sentinel-1 and Sentinel-2) based on a change detection technique. For calibration and validation of our model, ground measurements at 40 sampling sites in southern Manitoba, Canada, were carried out during the field campaign of SMAP Validation Experiment 2016 in Manitoba (SMAPVEX16-MB). The developed method is based on modelling soil moisture change by combining the difference in backscattered signal with that of NDVI observed on two consecutive acquisition days. This approach makes the assumption that the change in Normalized Difference Vegetation Index (NDVI) could better represent the attenuation of the backscattered signal resulting from the vegetation. Our model was evaluated over mature crop fields (canola, soybeans, wheat, corn and oats) using ground measurements and the agreement between satellite estimates and ground measurements was found satisfactory (RMSE lower than 0.093 m3/m3).
本研究的目的是利用基于变化检测技术的Sentinel数据(Sentinel-1和Sentinel-2)在田间尺度分辨率下量化农田土壤水分变化。为了校准和验证我们的模型,在马尼托巴省2016年SMAP验证实验(SMAPVEX16-MB)的现场活动期间,在加拿大马尼托巴省南部的40个采样点进行了地面测量。该方法结合连续两天观测到的NDVI与后向散射信号的差异,模拟土壤湿度变化。该方法假设归一化植被指数(Normalized Difference Vegetation Index, NDVI)的变化能更好地反映植被对后向散射信号的衰减。我们的模型在成熟的农田(油菜籽、大豆、小麦、玉米和燕麦)上进行了地面测量评估,发现卫星估计和地面测量之间的一致性令人满意(RMSE低于0.093 m3/m3)。

The coronavirus first outbreak in Wuhan city of China by December 2019. Due to its highly contagious power, they spread promptly in the four continents. Moreover, it devastating our daily lives and cause huge economic damage. Therefore, it is urgent to detect the positive cases at the earliest and put then under isolation. Automatic virus detection using Machine Learning will be a valuable contribution to prevent the spread of this epidemic. The purpose of this paper is to present short reviews on the coronavirus detection. In reviewing the existing works, we summarized and compared some related works performed on a collection of CT and X-ray images provided from infected patients. We conclude the paper with some discussions on how computer vision can response to urgent need to contribute in pandemics and to investigate many aspects of new viral replication and pathogenesis.
2019年12月,冠状病毒首次在中国武汉市爆发。由于其高度传染性,它们迅速在四大洲传播。此外,它破坏了我们的日常生活,造成巨大的经济损失。因此,尽早发现阳性病例并对其进行隔离是当务之急。使用机器学习的自动病毒检测将是防止这种流行病传播的宝贵贡献。本文的目的是对冠状病毒的检测进行简要综述。在回顾已有工作的基础上,我们总结并比较了一些对感染患者提供的CT和x线图像进行的相关工作。最后,我们讨论了计算机视觉如何响应流行病的迫切需要,以及如何研究新病毒复制和发病机制的许多方面。
