Information Extraction from Arabic Medications Leaflets 阿拉伯语药物单张信息提取
Adnan Yahya, Hala Salameh, Maram Belbeisi, Noor Shamasneh
Making information in electronic documents easily accessible has been a major concern over the past years. There has been increasing interest in gleaning information from unstructured text and presenting it as structured data using information extraction (IE). Since Arabic has seen major growth in web content, mainly unstructured text, the need for IE from Arabic documents has gained importance. The processing capacity needed for IE far exceeds human ability to extract knowledge manually. The medical field is one such area, where awareness of health issues makes the task of automating medical informatics crucial for better access to medical knowledge. Thus, work on extracting information from medical documents has increased rapidly. In this paper we address the issue of IE from Arabic drug leaflets. We use a combination of rule-based, machine learning and deep learning methods and employ a suit of tools that account for the particularities of Arabic to extract information from Arabic drug package inserts to make this information available in structured form and thus better accessible to regular users and health care providers. A prototype system that utilizes the IE results was developed with useful functionality such as alerting to possible Adverse Drug Reactions (ADR) and finding drug alternatives.
使电子文件中的信息易于获取是过去几年的一个主要问题。人们对从非结构化文本中收集信息并使用信息提取(information extraction, IE)将其表示为结构化数据越来越感兴趣。由于阿拉伯语在网络内容(主要是非结构化文本)方面有了很大的增长,因此对来自阿拉伯语文档的IE的需求变得越来越重要。IE所需的处理能力远远超过人类手动提取知识的能力。医学领域就是这样一个领域,对健康问题的认识使得自动化医学信息学的任务对于更好地获取医学知识至关重要。因此,从医疗文件中提取信息的工作迅速增加。在本文中,我们解决了从阿拉伯文药品传单IE问题。我们结合使用基于规则的机器学习和深度学习方法,并采用一套考虑阿拉伯语特殊性的工具,从阿拉伯语药品包装说明书中提取信息,使这些信息以结构化的形式提供给普通用户和医疗保健提供者,从而更好地访问这些信息。利用IE结果开发的原型系统具有有用的功能,例如警告可能的不良药物反应(ADR)和寻找药物替代品。

Discrete Hilbert Transform via Memristor Crossbars for Compact Biosignal Processing 基于忆阻交叉棒的离散希尔伯特变换在紧凑生物信号处理中的应用
Lei Zhang, Zhuolin Yang, Kedar K. Aras, Igor R. Efimov, G. Adam
The Hilbert transform is widely used in biomedical signal processing and requires efficient implementation. We propose the implementation of the discrete Hilbert transform based on emerging memristor devices. It uses two matrix multiplication layers using weights programmed in the memristor array and a linear Hadamard product calculation layer mappable to CMOS. The functionality was tested on a dataset of optical cardiac signals from the human heart. The results show negligible <1% angle error between the proposed implementation and the MATLAB function. It also has robustness to non-idealities. This proposed solution can be applied to bio-signal processing at the edge.

Artificial Intelligence in Medicine for Chronic Disease Classification Using Machine Learning 使用机器学习进行慢性疾病分类的医学人工智能
M. Rakhimov, Ravshanjon Akhmadjonov, Shahzod Javliev
Artificial intelligence (AI) systems in medicine are one of the most important modern trends in global healthcare. Artificial intelligence technologies are fundamentally changing the global healthcare system, making it possible to radically rebuild the system of medical diagnostics while reducing healthcare costs. AI is actively used in research to develop methods for diagnosing coronary heart disease (CHD). There are different types of CHD. Before treating a disease, it is necessary to determine which class of diseases it belongs to. Based on the feature space of the disease, it is possible to classify the type of CHD. Machine learning algorithms can solve this problem. The k-nearest neighbors (KNN) algorithm is a simple, easy-to-implement supervised machine learning algorithm that can be used to solve classification problems. The dataset is the more important part of the supervised machine learning algorithm for training. Gathering data is the most important step in solving any supervised machine learning problem. But choosing more important part from the collected data is one of the tasks to be solved. The main purpose of this study is to select more useful parametric attributes from the dataset to obtain a high F1-score of CHD classification.
医学中的人工智能(AI)系统是全球医疗保健领域最重要的现代趋势之一。人工智能技术正在从根本上改变全球医疗体系,使从根本上重建医疗诊断体系成为可能,同时降低医疗成本。人工智能被积极用于研究开发冠心病(CHD)的诊断方法。冠心病有不同的类型。在治疗疾病之前,有必要确定它属于哪一类疾病。根据疾病的特征空间,可以对冠心病的类型进行分类。机器学习算法可以解决这个问题。k近邻(KNN)算法是一种简单,易于实现的监督机器学习算法,可用于解决分类问题。数据集是监督机器学习算法中用于训练的更重要的部分。收集数据是解决任何监督机器学习问题最重要的一步。但是从收集到的数据中选择更重要的部分是需要解决的问题之一。本研究的主要目的是从数据集中选择更多有用的参数属性,以获得较高的冠心病分类f1分。

Proactive Computer Network Monitoring based on Homogeneous LSTM Ensemble 基于同构LSTM集成的主动计算机网络监控
R. Shikhaliyev
Computer networks are getting more complex these days. A computer network failure can result in the loss of important data, disruption of network services and applications, and economic loss and threaten national security. Therefore, it is crucial to detect failures on time and diagnose their root cause, which is possible with the help of proactive computer network monitoring. The paper proposes a conceptual model of a system for proactive computer network monitoring. Proactive monitoring is based on predicting the network behavior. To achieve high prediction accuracy, we propose to use a homogeneous ensemble, which consists of a single base learning algorithm. Base learning LSTM models for an ensemble of deep neural networks were created using the bagging algorithm. We use the CICIDS2017 intrusion detection evaluation dataset to evaluate the proposed approach. Experimental results show that our method is an effective approach to improving the accuracy of anomaly prediction in computer networks.

Real-time sleep prediction using a virtual sensor to estimate Heart Rate Variability through Respiratory Rate 实时睡眠预测使用虚拟传感器估计心率变异性通过呼吸率
Luigi Pugliese, Massimo Violante, Sara Groppo
One of the most important causes of death while driving is sleepiness. To solve this problem, different kinds of technologies are needed. A recent work presented an approach based on Photoplethysmogram (PPG) analysis to predict the sleep onset. As PPG is not always available, especially in the case of commercial of the shelf wearable devices that provide features such as heart beat and respiration rate, in the paper we present a novel approach to predict sleep onset, which leverages a virtual sensor able to provide an estimation of the PPG-related Heart Rate Variability (HRV) through Respiration Rate (RR) analysis. The experimental results show 100% sensitivity and specificity in the collected data.

Reinforcement Learning Based Robot Control 基于强化学习的机器人控制
Z. Guliyev, Ali Parsayan
Reinforcement learning (RL) has been proven to be a feasible method for learning complicated actions autonomously from sensory observations. Even though many of the deep RL studies have been centered on modelled control and computer games, which has nothing to do with the limits of learning in actual surroundings, deep RL has also revealed its potential in allowing robots to acquire complicated abilities in the real-world situations. Real-world robotics, on the other hand, is an intriguing area for testing the algorithms of this kind, because it is directly related to the learning procedure of humans. Deep RL might enable developing movement abilities without a precise modelling of the robot dynamics and with minimum engineering. However, because of hyper-parameter sensitivity and low sampling capability, it is difficult to implement deep RL to robotic tasks involving real-world applications. It is comparable simple to tune hyper-parameters in simulations, while it can be a challenging task when it comes to physical world, for example, biped robots. Acquiring the ability to move and perceive in the actual world involves a variety of difficulties, some are simpler to handle than others that are frequently overlooked in RL studies which are limited to simulated environments. This paper provides approaches to deal with a variety of frequent difficulties in deep RL arising while training a biped robot to walk and follow a specific path.
强化学习(RL)已被证明是一种从感官观察中自主学习复杂动作的可行方法。尽管许多深度强化学习研究都集中在建模控制和电脑游戏上,这与实际环境中的学习限制无关,但深度强化学习也显示了它在允许机器人在现实世界中获得复杂能力方面的潜力。另一方面,现实世界的机器人技术是测试这种算法的一个有趣领域,因为它与人类的学习过程直接相关。深度强化学习可以在不需要精确的机器人动力学建模和最少的工程设计的情况下开发运动能力。然而,由于深度强化学习的超参数敏感性和低采样能力,很难将其应用于实际应用的机器人任务。在模拟中调整超参数相当简单,而在物理世界中,例如双足机器人,这可能是一项具有挑战性的任务。获得在现实世界中移动和感知的能力涉及各种各样的困难,其中一些比其他困难更容易处理,而这些困难在仅限于模拟环境的强化学习研究中经常被忽视。本文提供了处理深度强化学习中训练双足机器人在特定路径上行走时出现的各种常见困难的方法。

A. Adamov, Gozel Khasanova
Thanks to Web, ubiquitous digital technologies and the increasing usage of digital environment by humans for work, entertainment, education and other activities, huge amounts of textual data is generated and available online. Text is the most informative and at the same time most sophisticated data type in terms of its comprehension by machines. The Text Analytics is a field that involves number of computer science disciplines to process textual data and transforms it into computer readable format suitable for another field of study Natural Language Processing to extract meaning.This research paper is an attempt to apply broad variety of statistical analysis methods to the corpora of several Turkic languages using Universal Declaration of Human Rights as a Corpus. Quantitative Text Analysis as a research area is focused on understanding the human language through statistics and numbers. As the language is the most effective tool to describe the social world, the Quantitative Text Analysis enables social exploration of the rial world at the scale.
由于网络、无处不在的数字技术以及人类越来越多地使用数字环境进行工作、娱乐、教育和其他活动,大量的文本数据在网上产生和可用。就机器的理解能力而言,文本是信息量最大,同时也是最复杂的数据类型。文本分析是一个涉及许多计算机科学学科的领域,用于处理文本数据并将其转换为适合于另一个研究领域的计算机可读格式,即自然语言处理以提取含义。本研究以《世界人权宣言》为语料库,尝试运用多种统计分析方法对几种突厥语语料库进行分析。定量文本分析作为一个研究领域的重点是通过统计和数字来理解人类语言。由于语言是描述社会世界最有效的工具,定量文本分析可以在规模上对现实世界进行社会探索。
