Spiking Neural Network can adapt to the environment if it has the capacity to learn based on spike timing-dependent plasticity (STDP) by which the synaptic weight gets modified based on time difference between pre and postsynaptic spikes. The classical pair-based STDP model which considers only a pair of pre and post spikes has failed to account for synaptic activity when driven by a series of spikes. Whereas, Triplet based STDP model provides best fit for the experimental data as well as maps on to the Bienenstock-Cooper-Munro (BCM) learning rule. Implementation of plasticity rules at circuit level is necessary for realizing efficient computational very large scale integration (VLSI) systems which incorporates learning and memory functions. The analog VLSI implementation of TSTDP available in literature so far requires external circuitry to identify precise timing between two immediate successive pre and post spikes. The TSTDP circuit proposed in this paper is capable of identifying precise time difference between any two spikes, provides potentiation or depression based on sign and strength of the time difference, and also inherits the BCM rule when driven with Poisson spike trains. The circuit has been simulated in LTspice-XVII with the “TSMC 180nm” technology library.
尖峰神经网络具有基于尖峰时间依赖可塑性(STDP)的学习能力,即根据前后尖峰的时间差来调整突触权值,从而能够适应环境。经典的基于对的STDP模型只考虑一对前后尖峰,无法解释由一系列尖峰驱动的突触活动。然而,基于三重态的STDP模型对实验数据的拟合效果最好,并且映射到Bienenstock-Cooper-Munro (BCM)学习规则。在电路级实现可塑性规则是实现高效的集成学习和记忆功能的计算型超大规模集成电路系统的必要条件。到目前为止,文献中可用的TSTDP的模拟VLSI实现需要外部电路来识别两个直接连续的前后尖峰之间的精确定时。本文提出的TSTDP电路能够精确识别任意两个尖峰之间的时间差,并根据时差的符号和强度提供增强或抑制,并且在泊松尖峰串驱动时继承了BCM规则。该电路已在LTspice-XVII中使用“TSMC 180nm”技术库进行了仿真。

In an effort to address the issue of low power and area constraints which are important pre-requisites to many applications in the field of signal processing, this work focuses on the implementation of a novel biphasic neuron architecture, that is proven to be energy efficient, and highly compact. The low power Adaptive exponential integrate and fire neuron (ADEx I&F), is implemented as a biphasic encoder in 180 nm CMOS Technology, and a SER of upto 60 dB and a figure of merit (FOM) of 0.26 pJ/conversion is achieved. The proposed biphasic encoder is found to exhibit similar performance characteristics with respect to the existing architectures while comprising of 52 % lesser number of transistors than the conventional biphasic neuron encoder models.

Tubes and Catheters are very important devices for saving patients' lives. There is a variety of tubes and Catheters; those especially used during this study are: Endotracheal tube (ETT), Nasogastric (NG)], and Swan Ganz catheter. Errors in positioning these kinds of devices, if not detected early my caused crucial complications (even death). Airway tube malposition in adult patients intubated is seen in up to 25% of cases. Doctors and nurses use checklists to make sure the medical procedure goes smoothly, but these steps take a long time and more resources with the possibility of human errors during verification protocols especially when hospitals are at full capacity. In this article, we propose using transfer learning to train and compare several Keras applications on classification tube problems; the best-selected networks can help in the development of CAD (Computer Aided Detection). The main advantage of using a single Deep Convolutional Neural Network DCNN to detect abnormal positioning of several lines based on chest X-ray image processing is to avoid the complexity caused by using a DCNN (Deep Convolutional Neural Network) network for each type of line. Efficient DCNN can detect abnormal positioning in real-time and immediately notify doctors to adjust tube position. All tested networks during this work are improved after augmentations and parameters tuning, we get the best score for Resnet50V2 model AUC (80%).
导管是挽救病人生命的重要设备。有各种各样的管子和导管;在本研究中特别使用的导管有:气管导管(ETT)、鼻胃导管(NG)和Swan Ganz导管。如果不及早发现这些设备的定位错误,可能会导致严重的并发症(甚至死亡)。气管管错位在成人患者插管见于高达25%的病例。医生和护士使用检查清单来确保医疗程序顺利进行,但这些步骤需要很长时间和更多资源,并且在验证协议期间可能出现人为错误,尤其是在医院满负荷运转的情况下。在本文中,我们提出使用迁移学习来训练和比较几种Keras在分类管问题上的应用;最佳选择的网络可以帮助CAD(计算机辅助检测)的发展。基于胸部x线图像处理,使用单个深度卷积神经网络DCNN检测多条线的异常定位,其主要优点是避免了对每条线使用一个深度卷积神经网络所带来的复杂性。高效的DCNN可以实时发现异常定位,并立即通知医生调整管位。经过增强和参数调优后,所有测试网络都得到了改进,我们获得了Resnet50V2模型AUC的最佳分数(80%)。

This work focuses on the potential of expert System(ES) in solving complicated and Contradicting problems in the field of power system planning. Conventional optimization methods are inappropriate in many cases of optimization problem solutions. Artificial Intelligence (AI) albeit rather Convenient for solution of some optimization problems of power systems, however, the need for good starting point helps greatly for achieving proper and fast conversion. Experience of professional engineers is very crucial in reaching the optimal solution. In this paper we introduce ES technique as a helpful tool in Micro Power grid (MPG) planning by suggesting a strong starting point for optimization techniques in both conventional and AI methods.

Effectiveness of the proposed knowledgebase is tested through the standard IEEE 14-bus system.

Remote electronic voting refers to the use of the computer and Internet to collocate votes in an election. Remote e-voting is convenient and provides easy access for voters. On other hand, it makes it easier to count the votes and generate reports for election operators. Over time, e-voting systems were developed until it reaches the level that we have today, and it is expected that they will continue to improve in the future. Nevertheless, recently there has been increasing criticism of remote e-voting systems' security and integrity. Also, concerns were raised about whether these systems can defend against cyber attacks. An effective remote e-voting system must meet a set of standards required from regulatory bodies. This paper discusses remote e-voting systems' design requirements as discussed in current literature. Then, we examine whether the current public infrastructure is capable of supporting an effective remote e-voting system that meets the design requirements. We found that the current technology infrastructure is not sufficient to support efficient remote e-voting systems, as the technologies that need to be implemented to meet the design requirements are victims of different cyber attacks.
远程电子投票是指利用计算机和互联网在选举中配置选票。远程电子投票很方便,为选民提供了方便的途径。另一方面,它使计票和为选举操作者生成报告变得更加容易。随着时间的推移,电子投票系统不断发展,直到达到我们今天的水平,预计它们将在未来继续改进。然而,最近有越来越多的人批评远程电子投票系统的安全性和完整性。此外,人们还担心这些系统能否抵御网络攻击。一个有效的远程电子投票系统必须满足监管机构要求的一套标准。本文讨论了当前文献中讨论的远程电子投票系统的设计要求。然后,我们考察了当前的公共基础设施是否能够支持满足设计要求的有效的远程电子投票系统。我们发现,目前的技术基础设施不足以支持高效的远程电子投票系统,因为需要实施的技术,以满足设计要求是不同的网络攻击的受害者。

The inclusion of women into the development and implementation of artificial intelligence and machine learning in the world is critical. The underrepresentation and lack of representation of women results in lower quality AI products. The AI consumer group is very diverse and the lack of diversity within the AI leadership and workforce creates a crisis within the AI industry. Additionally, because AI is fast-paced and has a high societal impact, not addressing this disparity has the potential to increase stereotypes, underrepresentation, and discrimination in career fields everywhere. This paper discusses the importance of women in the AI field, the barriers that they face, and a few solutions to eliminate gender-discrimination and gender-inequality for women of all ages. Women may experience increased discrimination in fields of underrepresentation, and this can discourage their desire to purse these career paths. The workplace needs to be aware of these struggles, provide resources for both men and women to address this, and invest in support for women to encourage their participation. As an emerging industry, the AI industry has an opportunity to address this gender gap before it becomes more pervasive and ingrained into the culture of AI. Together, we can have a significant impact on the future of AI, the community, and the products that consumers use.
让女性参与世界人工智能和机器学习的开发和实施至关重要。女性代表性不足和缺乏代表性导致人工智能产品质量较低。人工智能消费者群体非常多样化,人工智能领导层和劳动力内部缺乏多样性,这在人工智能行业内造成了危机。此外,由于人工智能是快节奏的,具有很高的社会影响,如果不解决这种差距,就有可能增加各地职业领域的刻板印象、代表性不足和歧视。本文讨论了女性在人工智能领域的重要性,她们面临的障碍,以及消除所有年龄段女性性别歧视和性别不平等的一些解决方案。在代表性不足的领域,女性可能会受到更多的歧视,这可能会打消她们追求这些职业道路的愿望。工作场所需要意识到这些挣扎,为男性和女性提供资源来解决这个问题,并投资支持女性以鼓励她们参与。作为一个新兴行业,人工智能行业有机会在性别差距变得更加普遍和根深蒂固之前解决这一问题。齐心协力,我们可以对人工智能、社区和消费者使用的产品的未来产生重大影响。

Low Power Wide Area Network (LPWAN) is a network technology that emanated from the swift advancement of the Internet of Things (IoT) market. It is characterized by low cost, long-range communications, low power consumptions, and better area coverage. However, LPWAN is faced with several challenges such as scalability, security, coexistence, management, and adoption. Recently, Cognitive Radio-LPWAN (CR-LPWAN) has been introduced to address some of these challenges to preserve the benefits of LPWAN. Therefore, this paper surveys and analyses recent works on CR-LPWAN to identify the existing challenges, possible solutions and open issues as research directions. This paper specifically focused on relevant works that addressed issues in standardization, design, development, and architecture and identified research directions for improving CR-LPWAN. About twenty (20) relevant articles were explored, and the findings revealed the existence of several issues and proposed solutions in the CR-LPWAN realm. The findings also revealed CR-LPWAN as a promising wireless communication technology and with more research attention, CR-LPWAN can be improved significantly.
低功耗广域网(LPWAN)是随着物联网(IoT)市场的迅速发展而产生的一种网络技术。它的特点是低成本、远距离通信、低功耗和更好的区域覆盖。然而,LPWAN面临着一些挑战,如可伸缩性、安全性、共存、管理和采用。最近,认知无线电-LPWAN (CR-LPWAN)被引入,以解决其中的一些挑战,以保持LPWAN的优势。因此,本文对当前CR-LPWAN的研究现状进行了调查和分析,以确定当前存在的挑战、可能的解决方案和有待解决的问题作为研究方向。本文重点介绍了CR-LPWAN在标准化、设计、开发和架构方面的相关工作,并确定了改进CR-LPWAN的研究方向。研究人员研究了大约20篇相关文章,发现了CR-LPWAN领域存在的几个问题并提出了解决方案。研究结果还表明,CR-LPWAN是一种很有前途的无线通信技术,随着研究的关注,CR-LPWAN可以得到显著的改进。

We develop a decentralized control method for a UAV swarm for a multitarget tracking application using the theory of decentralized Markov decision processes (Dec-MDPs). This study develops a UAV control strategy to maximize the overall target tracking performance in a decentralized setting. Motivation for this case study comes from the surveillance applications using UAV swarms. Decision-theoretic approaches are very difficult to solve due to high dimensionality and being computationally expensive. We extend an approximate dynamic programming method called nominal belief-state optimization (NBO) to solve the UAV swarm control problem for target tracking application. We also implement a centralized MDP approach as a benchmark to compare the performance of the Dec-MDP approach.
利用分散式马尔可夫决策过程(dec - mdp)理论,提出了一种用于多目标跟踪应用的无人机群分散控制方法。本文研究了一种分散环境下的无人机控制策略,以最大限度地提高总体目标跟踪性能。本案例研究的动机来自使用无人机群的监视应用。决策理论方法由于其高维性和计算成本高而很难求解。我们扩展了一种近似动态规划方法,称为标称信念状态优化(NBO),以解决目标跟踪应用中的无人机群控制问题。我们还实现了一个集中式MDP方法,作为比较Dec-MDP方法性能的基准。

Decision-theoretic approaches are very difficult to solve due to high dimensionality and being computationally expensive. We extend an approximate dynamic programming method called nominal belief-state optimization (NBO) to solve the UAV swarm control problem for target tracking application. We also implement a centralized MDP approach as a benchmark to compare the performance of the Dec-MDP approach.","PeriodicalId":443405,"journal":{"name":"2021 IEEE World AI IoT Congress (AIIoT)","volume":"283 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116398849","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}

Enhancement in the efficiency of surgical proficiency training system requires a continuous effort in surgical care atmosphere without any risk factor and it is known as a complex and challenging task nowadays. The process is exclusively relevant in training of technical skills specific to modern Minimally Invasive System (MIS) based procedures like keyhole surgery. However, modern surgical training systems are more intensive on the improvement of technical skills for dexterity, imagining and accurateness of the surgeons which are lacking in aspects of context-awareness and intra-operative real-time supervision. Context-aware intelligent training systems interpret the modern surgical condition and help surgeons to train on surgical tasks. Motivated by the development aspects and needs, this paper presents in depth review and highlights of the major challenging factors for haptic control interfacing, which are required to overcome in the future development of intelligent and highly integrated surgical training system for robotic surgery.
提高外科技能培训系统的效率,需要在无任何风险因素的情况下,在外科护理氛围中不断努力,是当今一项复杂而富有挑战性的任务。该过程专门与现代微创系统(MIS)手术(如锁眼手术)的技术技能培训相关。然而,现代外科培训系统更侧重于提高外科医生的灵巧性、想象力和准确性等技术技能,而缺乏情境感知和术中实时监督。上下文感知智能训练系统解释现代手术条件并帮助外科医生进行手术任务训练。本文从发展方面和需求出发,对触觉控制接口的主要挑战因素进行了深入的综述和重点分析,指出了未来机器人手术智能化、高度集成化手术训练系统发展中需要克服的主要挑战因素。

Mobile robots are increasingly common in society and are increasingly being used for complex and high-stakes tasks such as search and rescue. The growing requirements for these robots demonstrate a need for systems which can review and react in real time to environmental hazards, which will allow robots to handle environments that are both dynamic and dangerous. We propose and test a system which allows mobile robots to reclassify environmental objects during operation in conjunction with an edge system. We train an image classification model with 99 percent accuracy and deploy it in conjunction with an edge server and JSON-based ruleset to allow robots to react to and avoid hazards.
