Safety may depends crucially on making moral judgments. To date we have a lack of knowledge about the possibility of intervening in the processes that lead to moral judgments in relation to the behavior of artificial agents. The study reported here involved 293 students from the University of Siena who made moral judgments after reading the description of an event in which a person or robot killed other people or robots. The study was conducted through an online questionnaire. The results suggest that moral judgments essentially depend on the type of victim and that are different if they involve human or artificial agents. Furthermore, some characteristics of the evaluators, such as the greater or lesser disposition to attribute mental states to artificial agents, have an influence on these evaluations. On the other hand, the level of familiarity with these systems seems to have a limited effect.
安全可能在很大程度上取决于道德判断。迄今为止,我们对干预导致与人工主体行为相关的道德判断的过程的可能性缺乏了解。这里报道的这项研究涉及来自锡耶纳大学的293名学生,他们在阅读一个人或机器人杀死其他人或机器人的事件描述后做出道德判断。这项研究是通过在线问卷进行的。结果表明,道德判断本质上取决于受害者的类型,如果涉及人类或人工代理人,则会有所不同。此外,评估者的某些特征,如将心理状态归因于人工代理的倾向或多或少,对这些评估有影响。另一方面,对这些系统的熟悉程度似乎影响有限。

Color Lane Line Detection Using the Bhattacharyya Distance 基于Bhattacharyya距离的彩色车道线检测
J. Han, Chulhee Lee
In this paper, we propose a color lane line detection algorithm that can be used with moving vehicles. First, to reduce false detection and processing time, we considered the geometric relationship of the camera and the vanishing point. To effectively utilize color images for color line detection, we used the edge detection method based on the Bhattacharyya distance and a morphological operation. The proposed method was tested under various conditions (highway, urban, others; sunny, cloudy, early evening) and the experimental results show promising performance.

Focusing on prostate cancer patients, this research paper addresses the problem of bone metastasis diagnosis, investigating the capabilities of convolutional neural networks (CNN) and transfer learning. Considering the wide applicability of CNNs in medical image classification, VGG16 and DenseNet, as being two efficient types of deep neural networks, are exploited for images recognition, being used to properly classify an image by extracting its insightful features. The purpose of this study is to explore the capabilities of transfer learning in VGG16 and DenseNet application process, which will be able to classify bone scintigraphy images in patients suffering from prostate cancer. Efficient VGG16 and DenseNet architectures were built based on a CNN exploration process for bone metastasis diagnosis and then were employed to identify the metastasis from the bone scintigraphy image data. The classification task is a three-class problem, which classifies images as normal, malignant, and healthy images with degenerative changes. The results revealed that both methods are sufficiently accurate to differentiate the metastatic bone from degenerative changes as well as from normal tissue.
本研究以前列腺癌患者为研究对象,探讨了卷积神经网络(CNN)和迁移学习的能力,解决了骨转移诊断问题。考虑到cnn在医学图像分类中的广泛适用性,VGG16和DenseNet作为两种高效的深度神经网络,被用于图像识别,通过提取图像的深刻特征来对图像进行正确的分类。本研究的目的是探索迁移学习在VGG16和DenseNet应用过程中的能力,从而能够对前列腺癌患者的骨显像图像进行分类。基于CNN探索过程构建高效的VGG16和DenseNet架构,用于骨转移诊断,然后利用骨显像数据识别转移。分类任务是一个三类问题,将图像分为正常、恶性和具有退行性变化的健康图像。结果表明,这两种方法都足够准确地区分转移性骨与退行性变化以及正常组织。

Progress and Demonstrations on Space Division Multiplexing 空分复用技术的研究进展与示范
Charalampos Papapavlou, Konstantinos Paximadis, Giannis Tzimas
As optical networks urgently seek for extra capacity, Space Division Multiplexing (SDM) seems to be able to provide it. SDM can deploy multiple spatial channels in multi-core (MCFs) and/or multi-mode fibers (MMFs), and so, can increase the total transmission capacity. Specific integrated and scalable components will be needed to support the new multiplexing technology. In this paper we present a brief survey of recent progress in SDM and a taxonomy of up to date SDM experimental demonstrations and SDM network components. Finally we are discussing SDM research challenges and address fields of future interest.
在光网络迫切需要额外容量的情况下,空分复用(SDM)似乎能够满足这一需求。SDM可以在多核(mcf)和/或多模光纤(mmf)中部署多个空间信道,从而增加总传输容量。将需要特定的集成和可扩展组件来支持新的多路复用技术。本文简要介绍了SDM的最新进展,并对最新的SDM实验演示和SDM网络组件进行了分类。最后,我们将讨论SDM研究的挑战和未来感兴趣的领域。

A. Chorianopoulos, Ioannis Daramouskas, I. Perikos, F. Grivokostopoulou, I. Hatzilygeroudis
Breast Cancer is one of the most common cancers among women that affects about 10% of women worldwide. Although there are available treatments for bread cancer, the real challenge is to be properly detected it in early stages, a challenge that doctors and patients encounter constantly. In this study, we examine the performance of different deep learning models and depth-wise convolutional neural networks in medical imaging and assess their performance on breast cancer detection from ultrasounds and breast histopathology images. Experimental results suggest that the proposed deep learning models can effectively recognize breast cancer from ultrasound and histopathology images. The performance of the Convolutional Neural Network models reached 96.82% accuracy on ultrasounds, 88.23% on breast histology with cases of Invasive Ductal Carcinoma (IDC) and 91.04% on cancer-free tissue. The results are very promising and point out that deep-learning methods and depth-wise convolutional neural networks are very assistive in the diagnosis of breast cancer from ultrasound and histopathology images.
乳腺癌是女性中最常见的癌症之一,影响着全球约10%的女性。虽然有治疗面包癌的方法,但真正的挑战是在早期阶段被正确发现,这是医生和病人经常遇到的挑战。在本研究中,我们研究了不同深度学习模型和深度卷积神经网络在医学成像中的性能,并评估了它们在超声和乳腺组织病理学图像中检测乳腺癌的性能。实验结果表明,所提出的深度学习模型可以有效地从超声和组织病理学图像中识别乳腺癌。卷积神经网络模型对超声的准确率为96.82%,对乳腺浸润性导管癌(Invasive Ductal Carcinoma, IDC)的准确率为88.23%,对无癌组织的准确率为91.04%。结果非常有希望,并指出深度学习方法和深度卷积神经网络在从超声和组织病理学图像诊断乳腺癌方面非常有帮助。

Applying a Convolutional Neural Network in an IoT Robotic System for Plant Disease Diagnosis 卷积神经网络在植物病害诊断物联网机器人系统中的应用
Apostolos Xenakis, Georgios Papastergiou, V. Gerogiannis, G. Stamoulis
Plant diseases are major threat to green product quality and agricultural productivity. Agronomists and farmers often encounter great difficulties in early detection of plant diseases and controlling their potential production damages. Thus, it is of great importance for stakeholders to diagnose plant diseases at very early stages of plant growing by exploiting state-of-the art technologies, consider appropriate actions and avoid further economic losses. Artificial Intelligence (AI) techniques, field sensors, data analytics and inference algorithms are some contemporary tools which could be helpful for early plant disease diagnosis. In this paper, we present a plant Disease Diagnosis Support System (DDSS) that utilizes an Internet of Things platform to control a lightweight robotic system. The DDSS applies a Convolution Neural Network learning algorithm to perform early plant disease diagnosis and classification. The system can help farmers to apply appropriate precision agriculture actions and better control their production. The proposed DDSS achieves around 98% success classification rate, according to our demonstration case study.
植物病害是影响绿色产品质量和农业生产力的主要威胁。农学家和农民在早期发现植物病害和控制其潜在的生产损害方面经常遇到很大的困难。因此,对于利益相关者来说,利用最先进的技术在植物生长的早期阶段诊断植物病害,考虑适当的行动,避免进一步的经济损失是非常重要的。人工智能(AI)技术、现场传感器、数据分析和推理算法是一些有助于植物早期疾病诊断的现代工具。在本文中,我们提出了一种植物疾病诊断支持系统(DDSS),该系统利用物联网平台控制轻型机器人系统。DDSS采用卷积神经网络学习算法进行植物病害的早期诊断和分类。该系统可以帮助农民采取适当的精准农业行动,更好地控制他们的生产。根据我们的演示案例研究,所提出的DDSS的分类成功率约为98%。

Andreas Kaloudis, D. Tsolis, Theodore Koutsobinas
The major perspective of this paper is to provide more evidence into the empirical determinants of capital structure choice by focusing and discussing the relative importance of firm-specific and macroeconomic variables from an alternative scope in U.S. This study extends the empirical research on the topic of capital structure by focusing on a quantile regression method in order to investigate the behavior of firm-specific characteristics and macroeconomic variables across all quantiles of distribution of leverage (total debt, long-terms debt and short-terms debt). We thus based on a partial adjustment model, find that long-term and short-term debt ratios varying regarding their partial adjustment speeds; the short-term debt raised up while the long-term debt ratio slows down for same periods.
本文的主要观点是通过关注和讨论美国企业特定变量和宏观经济变量的相对重要性,为资本结构选择的实证决定因素提供更多证据。本研究通过关注分位数回归方法扩展了对资本结构主题的实证研究,以调查美国所有分位数的企业特定特征和宏观经济变量的行为杠杆的分布(总债务、长期债务和短期债务)。因此,我们基于部分调整模型,发现长期和短期债务比率随其部分调整速度而变化;同期,短期负债率上升,长期负债率下降。

Synchronous and Asynchronous Learning Methods under the light of General Data Protection Regulation 《通用数据保护条例》下的同步和异步学习方法
Eirini Mougiakou, Spyros Papadimitriou, M. Virvou
The continuous evolution of technology affects various areas of people’s daily lives. One of them is the field of education, where the use of technological means allows alternative ways of teaching. The spread of the SARS-CoV-2 coronavirus, which has led to the closure of educational institutions in many countries, has increased the significance of educational platforms. Some platforms allow synchronous communication between the tutor and the student, i.e., the tutoring process takes place at a predetermined time, simulating conventional training. Asynchronous educational platforms enable the student to study and solve exercises in the time and at the pace of their own choice. However, there are questions about users’ data, especially considering the General Data Protection Regulation 1 (GDPR) in force since 25 May 2018. In this article, we describe the features that distinguish synchronous from asynchronous learning systems and identify their points of impact with specific GDPR elements, respectively. Particularly for the asynchronous method, we focus on platforms that process user data and appropriately adapt the educational material. Having identified the impact points, we address the issue by providing guidelines for similar system designers. We also compare the two methods in terms of their benefits, taking into account the design needed for GDPR compliance.
科技的不断发展影响着人们日常生活的各个领域。其中之一是教育领域,技术手段的使用允许了其他教学方式。随着新冠肺炎疫情的蔓延,许多国家的教育机构被迫关闭,教育平台的重要性日益凸显。一些平台允许导师和学生之间的同步通信,即辅导过程在预定的时间进行,模拟传统的培训。异步教育平台使学生能够按照自己选择的时间和节奏学习和解决习题。然而,用户数据存在问题,特别是考虑到自2018年5月25日起生效的通用数据保护条例1 (GDPR)。在本文中,我们描述了区分同步学习系统和异步学习系统的特征,并分别确定了它们与特定GDPR元素的影响点。特别是对于异步方法,我们将重点放在处理用户数据并适当调整教育材料的平台上。确定了影响点之后,我们通过为类似的系统设计人员提供指导方针来解决这个问题。考虑到GDPR合规性所需的设计,我们还比较了两种方法的好处。

Virvou","doi":"10.1109/IISA50023.2020.9284341","DOIUrl":"https://doi.org/10.1109/IISA50023.2020.9284341","url":null,"abstract":"The continuous evolution of technology affects various areas of people’s daily lives. One of them is the field of education, where the use of technological means allows alternative ways of teaching. The spread of the SARS-CoV-2 coronavirus, which has led to the closure of educational institutions in many countries, has increased the significance of educational platforms. Some platforms allow synchronous communication between the tutor and the student, i.e., the tutoring process takes place at a predetermined time, simulating conventional training. Asynchronous educational platforms enable the student to study and solve exercises in the time and at the pace of their own choice. However, there are questions about users’ data, especially considering the General Data Protection Regulation 1 (GDPR) in force since 25 May 2018. In this article, we describe the features that distinguish synchronous from asynchronous learning systems and identify their points of impact with specific GDPR elements, respectively. Particularly for the asynchronous method, we focus on platforms that process user data and appropriately adapt the educational material. Having identified the impact points, we address the issue by providing guidelines for similar system designers. We also compare the two methods in terms of their benefits, taking into account the design needed for GDPR compliance.","PeriodicalId":109238,"journal":{"name":"2020 11th International Conference on Information, Intelligence, Systems and Applications (IISA","volume":"7 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129839884","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}
