With the introduction of Mobile Cloud Computing (MCC), the notion of leveraging cloud-hosted components to get around mobile devices' resource constraints became more widely accepted. However, as smartphones and tablets gained popularity, the definition of MC evolved. Although aggregating several devices - sometimes referred to as a 'cloud of devices' - is also taken into consideration, MCC mostly involves employing mobile devices to access cloud-hosted services these days. With more individuals owning several mobile devices, apps that let users share hardware and software resources across many devices are growing in popularity. Decentralised coordination, resource sharing, and communication amongst several mobile devices have consequently gained significance. The capability of combining several mobile devices running the same mobile application into one computing environment that effectively and decentralised makes use of all available hardware and software resources is the focus of this paper's exploration of 'horizontal scalability' in applications. Designing mobile apps as collections of RESTful micro-services and enabling communication between these services using low-bandwidth IoT protocols is one possible way to do this. The results of performance assessments on mobile devices running RESTful micro-services and interacting with the CoAP IoT protocol in a range of WIFI settings are presented in this paper. © 2024 IEEE.

Currently, the performance of the police in Indonesia is often in the spotlight of the public with cases that occur, both on a national and regional scale, including personal experiences who also feel disappointed with the performance of the police. The cases, such as the rape of three children by a biological father in East Luwu, and the barrage of other cases that have occurred, in their handling have left the public disappointed, giving rise to the hashtag percumlaporpolisi on social media, especially on twitter. This hashtag became trending and was widely responded to by the public. Using free hashtag keywords, tweet data is collected using Twitter's API for sentiment analysis. The datasets obtained from the crawling results is the latest data with a total of 100 datasets. This study applies the naïve bayes algorithm using textblob which aims to determine the value of polarity and subjectivity. From the results of the analysis carried out, the words that appear most often are useless police, police chief, and policeman. While the results of the sentiment analysis that has been carried out are 40 percent positive sentiment, 40 percent are neutral sentiment and 10 percent are negative sentiment from the hashtags used. From these results, according to the keywords used, the percentage of negative sentiment should be greater than positive and neutral sentiment. It is necessary to conduct a more in-depth study related to the model used in the next research. © 2023 IEEE.

Neural collapse provides an elegant mathematical characterization of learned last-layer representations, also known as features, and classifier weights within deep classification models. The result not only provides insights into deep models but also catalyzes the development of new techniques for improving them. However, most of the existing empirical and theoretical studies into neural collapse center around scenarios where the number of classes is small relative to the dimensionality of the feature space. This paper introduces a generalization of neural collapse to encompass scenarios where the number of classes surpasses the dimension of feature space, which broadly occurs for language models, information retrieval systems, and face recognition applications. A key technical contribution is the introduction of the concept of softmax code, defined as a collection of points that maximizes the minimum one-vs-rest margin, to describe the arrangement of class-mean features. We provide empirical study to verify the prevalence of generalized neural collapse in practical deep neural networks. Moreover, we provide theoretical study to show that the generalized neural collapse provably occurs under an unconstrained feature model with spherical constraint, subject to specific technical conditions on feature dimension and the number of classes.

We consider a source node deployed in a real-time monitoring application that needs to sample a stochastic process and convey its state timely and accurately to a destination over a wireless ON/OFF channel. The source can either process a raw sample to determine its current state and transmit that information or transmit the raw sample and let the destination determine the state. The source is subjected to an average cost constraint, and it cannot sample, process, and transmit at all the time instants due to the associated costs. When the destination does not receive information, it uses the previous information as an estimate of the current state, which, if it matches the actual state at the source, the distortion is considered to be zero. The objective is to minimize average expected distortion subject to constraints on the average expected age of information (AoI) of states of interest and costs incurred by the source, where the AoI of a state increases if no status update is received, else drops to unity. We derive a stationary randomized policy (SRP) to solve the formulated problem, for which we obtain the expression for the expected AoI under the SRP using a lumpability argument on the two-dimensional discrete-time Markov chain formed using AoI and instantaneous distortion as states. We extensively study the impact of the system parameters on the average distortion under the SRP and draw significant conclusions. © 2023 IFIP.

As the number of video streaming platforms is growing, the risk factor associated with illegal and inappropriate content streaming is increasing exponentially. Therefore, monitoring such content is essential. Many researches have been conducted on classifying encrypted videos. However, most existing techniques only pass raw traffic data into classification models, which is an ineffective way of training a model. This research proposes a bucket-based data pre-processing technique for a video identification in network traffic. The bucketed traffic is then incorporated with a fine-tuned word2vec-based neural network to produce an effective encrypted video classifier. Experiments are carried out with different numbers and sizes of buckets to determine the best configuration. Furthermore, previous research has overlooked the phenomenon of concept drift, which reduces the effectiveness of a model. This paper also compares the severity of concept drift on the proposed and previous technique. The results indicate that the model can predict new samples of videos with an overall accuracy of 81% even after 20 days of training. © 2022, EasyChair. All rights reserved.

Recent dual in-line memory modules (DIMMs) are starting to support processing-in-memory (PIM) by associating their memory banks with processing elements (PEs), allowing applications to overcome the data movement bottleneck by offloading memory-intensive operations to the PEs. Many highly parallel applications have been shown to benefit from these PIM-enabled DIMMs, but further speedup is often limited by the huge overhead of inter-PE collective communication. This mainly comes from the slow CPU-mediated inter-PE communication methods, making it difficult for PIM-enabled DIMMs to accelerate a wider range of applications. Prior studies have tried to alleviate the communication bottleneck, but they lack enough flexibility and performance to be used for a wide range of applications. In this paper, we present PID-Comm, a fast and flexible inter-PE collective communication framework for commodity PIM-enabled DIMMs. The key idea of PID-Comm is to abstract the PEs as a multi-dimensional hypercube and allow multiple instances of inter-PE collective communication between the PEs belonging to certain dimensions of the hypercube. Leveraging this abstraction, PID-Comm first defines eight interPE collective communication patterns that allow applications to easily express their complex communication patterns. Then, PIDComm provides high-performance implementations of the interPE collective communication patterns optimized for the DIMMs. Our evaluation using 16 UPMEM DIMMs and representative parallel algorithms shows that PID-Comm greatly improves the performance by up to $5.19 \times$ compared to the existing inter-PE communication implementations. The implementation of PIDComm is available at https://***/AIS-SNU/PID-Comm.

Dengue fever remains a serious threat to public health in Bangladesh and in many other tropical and subtropical locations. The prediction of dengue risk zones depends on early and accurate prediction of dengue risk zones. This study follows machine learning techniques to analyze weather data including temperature, humidity, precipitation, and wind speed to predict dengue risk levels. It follows a methodology of data preprocessing, model training using accuracy, precision, recall and F1 score. Several models including Support Vector Machine, Random Forest as well as Gradient Boosting have been applied and compared. The results have shown that the Gradient Boosting has outperformed all the models with an accuracy of 99.54%. The study shows how machine learning can improve dengue risk zone prediction and support evidence-based public health decisions.

IEEE Workshop on Applications of computer Vision (WACV)

作者： Lahiru Wijayasingha Homa Alemzadeh John A. Stankovic Computer Science Department University of Virginia USA Electrical and Computer Engineering Department University of Virginia USA

Monocular depth estimation is an important step in many downstream tasks in machine vision. We address the topic of estimating monocular depth from defocus blur which can yield more accurate results than the semantic based depth estimation methods. The existing monocular depth from defocus techniques are sensitive to the particular camera that the images are taken from. We show how several camera-related parameters affect the defocus blur using optical physics equations and how they make the defocus blur depend on these parameters. The simple correction procedure we propose can alleviate this problem which does not require any retraining of the original model. We created a synthetic dataset which can be used to test the camera independent performance of depth from defocus blur models. We evaluate our model on both synthetic and real datasets (DDFF12 and NYU depth V2) obtained with different cameras and show that our methods are significantly more robust to the changes of cameras.

This paper proposes a containment control law for a heterogeneous multi-agent system (MAS) by using the binary relative position measurements of the agents and the targets. Unlike the existing methods, this approach relaxes the necessity for exact position measurements as feedback to the agents, thereby the control protocol can be executed with less accurate sensors. To the best of authors’ knowledge, this is the first attempt to design the containment law for a heterogeneous MAS based on the binary relative position measurements. Using non-smooth Lyapunov analysis, we establish the convergence of the proposed containment law under a detailed-balanced directed network with any positive control gain. The numerical simulations substantiate the efficacy of the proposed binary measurement-based containment law. © 2024 IEEE.

Data security is of the utmost importance in wireless sensor networks due to the massive amounts of data collected and sent between nodes. An improved security method for wireless sensor networks is presented in this paper. This mechanism takes into account the application, the security level, and the bit error rate simultaneously. In order to provide the user with the ability to select between unsecure and secure modes, we made use of reserved bits of the frame control field that are contained within the communication header. The Secured and Intelligent Data Transmission Protocol (SIDTP) is the name of the unified perceptual information transmission model that is established in this research. Its purpose is to compensate for the unequal distribution of cognitive radio users across different wireless LANs. For the purpose of determining whether or not the suggested scheme is effective, the proposed model will be cross-validated with the traditional data transmission model known as Wireless Data Transmission Protocol (WDTP). The approach has the potential to optimize the utilization of spectrum resources in an efficient manner. In addition, to help lessen the risks connected with wireless networks, this study lays out a technique for transmitting data using cyclic delay full diversity sensing information coding. In order to evaluate the performance of the system against a variety of correlation coefficients, we developed a system simulation model. The result of the study showed that cyclic delay diversity systems had overall interference intensity similar to frequency division duplex as well as time division duplex. As an added bonus, this enhances its anti-jamming attack capabilities. The proposed system has been planned and implemented, and significant trials have been carried out in an industrial setting. Additionally, a prototype of the system has been designed. Compared to conventional communication interfaces that are only equipped with a single wireless interf
