This paper presents a framework to apply Reinforcement Learning control algorithm on benchmark nonlinear dynamical systems. This work focuses on a novel Artificial Neural Network (ANN) based dynamic programming approach using Value Iteration to obtain optimal control for continuous-time nonlinear system. In particular, Coupled Tank System has been chosen to represent benchmark nonlinear dynamical system. The proposed Artificial Neural Network-Reinforcement Learning (ANN-RL) algorithm, Naive Reinforcement Learning (Naive-RL) algorithm and traditional PID control schemes are investigated on coupled tank system. The ANN-RL algorithm performs better than the Naive-RL and PID controllers in terms of steady state error, stability, oscillations and overshoot.

The Intelligent Medicine box is an effective health-care product that is implemented using a physically inexpensive medicine box powered by IoT devices and an application powered by Android operating system. The Android application is used to start a new medication and store the treatment details along with the medicine history. This application also provides an effective platform for the user to schedule an appointment with the doctor seamlessly. In addition to this the android application has an inbuilt prescription which will be beneficial in times of pandemic. The user can also add custom treatment plan if necessary. The medicine box alerts the user at the correct time to take the medicine. The box produces audio and illuminates the correct container number, thus making it fool proof and prevents the user from taking the wrong medicine. The Intelligent medicine box proposed by us is a very effective solution in the Health care sector and will reduce the care giver’s burden.

Sign Language Recognition(SLR) is a complex gesture recognition problem because of the quick and highly coarticulated motion involved in gestures. This research work focuses on Fingerspelling recognition task, which constitutes 35% of the American Sign Language (ASL). Fingerspelling identifies the word letter by letter. Fingerspelling is used for signing the words which do not have designated ASL signs such as technical terms, content words and proper nouns. In our proposed work for ASL Fingerspelling recognition, we consider ChicagoFSWild dataset which consists of occlusions and images captured in varying illuminations, lighting conditions (in the wild environments). The optical flow is obtained from Lucas-Kanade algorithm, prior is generated, images are resized and cropped with face-roi technique to get the region of interest (ROI). The visual attention mechanism attends to the ROI iteratively. ResNet, pretrained on Imagenet is used for the extraction of spatial features. The Bi-LSTM network with Connectionist Temporal Classification (CTC) is used to predict the sign. It provides the accuracy of 57% on ChicagoFSWild dataset for Fingerspelling recognition task.
手语识别是一个复杂的手势识别问题,因为手势具有快速和高度的协同运动。本研究的重点是占美国手语(ASL) 35%的手指拼写识别任务。手指拼写识别一个字母一个字母的单词。指拼是指对专业术语、实词、专有名词等没有指定手语符号的单词进行手语。在我们提出的ASL手指拼写识别工作中,我们考虑了芝加哥野生数据集,该数据集由不同照明、照明条件下(在野生环境中)捕获的遮挡和图像组成。利用Lucas-Kanade算法获取光流,生成先验,利用人脸感兴趣区域技术对图像进行调整和裁剪,得到感兴趣区域。视觉注意机制对ROI的响应是迭代的。在Imagenet上进行预训练的ResNet用于提取空间特征。采用连接时间分类(CTC)的Bi-LSTM网络进行符号预测。在chicagoofswild数据集上提供57%的准确率用于指纹识别任务。

Contribution of social network is not only limited to inter-personal relationship, but there are increasing number of research works carried out towards other arena of commercial applications harnessing the potential of social network. Irrespective of decades of work being carried out in social networking, the idea of using social networking towards crowdsourcing has not received much attention owing to different levels of research challenges. Existing studies have no reported discussion about this and therefore, this paper contributes towards exploring the strength and weakness of existing approaches of building analytics on social networking in order to understand the possible challenges that crowdsourcing encounters while dealing massive and unstructured data. The paper also contributes towards illustrating research trends highlighting the possible limitations.
社交网络的贡献不仅局限于人际关系,而且越来越多的研究工作正朝着利用社交网络潜力的其他商业应用领域开展。尽管在社交网络领域已经开展了几十年的工作,但由于不同程度的研究挑战,将社交网络用于众包的想法并没有受到太多关注。现有的研究没有关于这方面的讨论,因此,本文有助于探索在社交网络上构建分析的现有方法的优缺点,以便了解众包在处理大量非结构化数据时可能遇到的挑战。本文还有助于说明研究趋势,突出可能的局限性。

The IoT has brought a digital revolution in connecting vast number of heterogeneous devices together through wireless communication. Definitely it brings a comfort and convenience to the people’s life but on the counterpart the security, privacy and information leakage has become a prime concern specially in the area of finance, trading and healthcare. By the rapid growth of the market low power wide area network technologies have become the area of interest. Narrow band IoT (NB-IoT) and Long range (LoRa) are quite efficient in providing indoor and outdoor coverage with low data rate. Unlicensed LoRa supports a long-range coverage with longer battery life, cost, capacity. While, licensed NB-IoT benefits in terms of latency, reliability, QoS and range. Both the protocols are encapsulated with cryptographic algorithms to provide the secure communication. But still are vulnerable to a wide range of attacks. In this paper network architecture, vulnerabilities, possible security breaches and counter solutions of NB-IoT and LoRa are discussed.
物联网带来了一场数字革命,通过无线通信将大量异构设备连接在一起。毫无疑问,它给人们的生活带来了舒适和便利,但与此同时,安全、隐私和信息泄露已成为人们关注的主要问题,特别是在金融、贸易和医疗保健领域。随着市场的快速增长,低功耗广域网技术已成为人们关注的领域。窄带物联网(NB-IoT)和远程物联网(LoRa)在提供低数据速率的室内和室外覆盖方面非常有效。未经许可的LoRa支持远程覆盖,具有更长的电池寿命、成本和容量。而授权的NB-IoT则在延迟、可靠性、QoS和范围方面具有优势。这两种协议都用加密算法封装,以提供安全的通信。但仍然容易受到各种各样的攻击。本文讨论了NB-IoT和LoRa的网络架构、漏洞、可能的安全漏洞和应对方案。

Sentiment analysis is an important domain in Natural Language Processing (NLP) since it is an efficient way to extract features and user sentiments from textual data. Performing sentiment analysis of big data in the tourism industry is useful for businesses to understand the needs of their customers and improve hotel facilities to increase customer satisfaction. This paper aims to compare, analyze and employ different types of supervised, unsupervised, and pre-trained models. The supervised models - Decision Trees, XGBoost, Multinomial Naïve Bayes, Multinomial Logistic Regression, SVM, and Stochastic Gradient Descent were tested and the parameters were optimised using GridSearchCV. Two unsupervised models, K-means clustering and Latent Dirichlet Allocation were implemented with TF-IDF and Word2Vec embeddings. The pre-trained models, VADER and TextBlob were also implemented. The labelled dataset used for this study contains user reviews of hotels around the world, where each review is classified as positive, neutral, or negative. The SVM model resulted in the highest weighted F1 score of 0.8516.

Recent research works have increasingly focused on gaining a better understanding of visual perception from brain activity. This work was partially motivated by functional Magnetic Resonance Imaging (fMRI) based studies on the neurobiology of "mental images" and Brain-Computer Interface (BCI) devices. The ultimate objective is to recreate thoughts from brain activity using generative AI models. It is crucial to extract and enumerate the differences between visual perception (when a stimulus is present) and visual imagery (the recall of the stimulus after that) by the brain. In this work, we determine that it is possible to detect changes in brain activity due to differences in Visual Perception and Imagery even while using EEG signal features recorded with limited channels. The first step in this process was doing a spatiotemporal-based feature estimation on the EEG data for seven people across all channels and trials. Results indicate that Alpha Band power, an essential characteristic in the posterior electrodes and indicating a parieto-occipital origin, significantly differed across the different channels.
最近的研究工作越来越集中于从大脑活动中获得对视觉感知的更好理解。这项工作的部分动机是基于功能性磁共振成像(fMRI)对“心理图像”和脑机接口(BCI)设备的神经生物学研究。最终目标是使用生成式人工智能模型从大脑活动中重建思想。提取和列举视觉感知(当刺激存在时)和视觉意象(之后大脑对刺激的回忆)之间的差异是至关重要的。在这项工作中,我们确定即使使用有限通道记录的脑电图信号特征,也有可能检测到由于视觉感知和图像差异而导致的大脑活动变化。这个过程的第一步是对所有通道和试验的7个人的脑电图数据进行基于时空的特征估计。结果表明,不同通道的α带功率显著不同,α带功率是后电极的基本特征,表明顶枕起源。

Text from image documents must be recognized for its usage. Various tasks such as plagiarism & error check, language analysis, information capture rely on the accuracy of this text conversion. OCR systems convert the document images to their text equivalent. These OCR systems are prone to introducing errors during the recognition process.This work reports a system developed to ingest image documents which is converted to text using available OCR technologies. The recognized text, subsequently, is processed with deep network language models to enhance the accuracy of text. The system consists of a client server architecture with user interface available from web application as well as from mobile app. For the language models, encoder-decoder based BART & MarianMT are used. The results obtained demonstrate a 35% reduction in WER using the BART language model.

The system consists of a client server architecture with user interface available from web application as well as from mobile app. For the language models, encoder-decoder based BART & MarianMT are used. The results obtained demonstrate a 35% reduction in WER using the BART language model.","PeriodicalId":150346,"journal":{"name":"2023 IEEE 8th International Conference for Convergence in Technology (I2CT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131425586","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}

Cricket is the most popular sport and most watched now a day. Test matches, One Day Internationals (ODI), and Twenty20 Internationals are the three forms in which it is played. Until the last ball of the last over, no one can predict who would win the match. Machine learning is a new field that uses existing data to predict future results. The goal of this study is to build a model that will predict the winner of a One-Day International Match before it begins. Machine learning techniques will be used on testing and training datasets to predict the winner of ODI match that will be based on the specified features. The data for the model is collected from Kaggle and some of the data are collected from the different cricket websites because the data obtained from Kaggle has only matches up until July 2021. Two algorithms were used for the prediction, K-Nearest and XGBoost, out of these two algorithms prediction accuracy of 91% was obtained by K-Nearest Neighbor Algorithm and prediction accuracy of 89% was obtained by XGBoost Algorithm
板球是最受欢迎的运动,也是每天观看人数最多的运动。测试赛、一日国际赛(ODI)和二十20国际赛是板球的三种形式。直到最后一局的最后一个球,谁也无法预测谁将赢得这场比赛。机器学习是一个利用现有数据预测未来结果的新领域。这项研究的目标是建立一个模型,在一天的国际比赛开始前预测获胜者。机器学习技术将用于测试和训练数据集,以根据指定的特征预测ODI比赛的获胜者。该模型的数据是从Kaggle收集的,有些数据是从不同的板球网站收集的,因为从Kaggle获得的数据只匹配到2021年7月。预测采用了K-Nearest和XGBoost两种算法,其中K-Nearest Neighbor算法预测准确率为91%,XGBoost算法预测准确率为89%
