The growing field of Content-Based Medical Image Retrieval (CBMIR) plays an integral role in the diagnosis and treatment plan of numerous diseases, including cancer. However, the effective representation of gigapixel medical images via a large number of extracted features remains a challenging task, crucially influencing other processes in a digital workflow. In this paper, we propose a novel QR code representation strategy to enhance retrieval performance. Unlike the traditional one-dimensional binary representation methods (i.e., barcodes), this 2D approach captures more intricate and informative patterns from the features by differentiating each pair of features resulting in a 2D binary vector. We delve into three distinct QR code generation strategies, namely, the Thresholding QR, the MinMax QR, and the Hybrid QR, each offering unique strengths. Our experiments on representing whole slide images of the Cancer Genome Atlas (TCGA) dataset reveal that while the Hybrid QR tends to provide balanced performance, there are instances where the other two methods outshine. Even though this approach requires more memory usage, the considerable enhancement in accuracy justifies this trade-off;obviously, in medical applications, accuracy holds the highest priority. Hence, the findings indicate that QR codes can effectively improve the performance of CBMIR systems by not only accelerating the retrieval process but also increasing the accuracy of image retrieval, leading to potentially more accurate diagnoses and treatment planning. © 2023 IEEE.

Semantic interoperability is one of the most critical challenges for software developers while integrating two or more context-aware systems. In such circumstances, it is essential to understand the meaning and interpretation of various contexts in different business domains and to align context ontologies together. Our investigations reveal that existing works poorly address these requirements. To fill this gap, this paper proposes the Ontology as a Service (OaaS) approach to facilitate the semantic interoperability of context-aware systems. In the proposed solution, the complexities of semantic interoperability are resolved and handled by a standalone ontology service, which can be easily reused and consumed by different ontology service consumers and brokers. The proposed ontology service includes several ontology repositories, a web service that positions a context concept in the existing ontologies and another web service that maps the relationship between existing context concepts. We evaluated our approach with a case study that resolves three semantic differences between two IoT applications originating from heterogeneous domains of smart home and health environments. © 2023 IEEE.

Customizing packet processing is crucial in the evolving network landscape, especially with the rise of 5G telecommunications and beyond. software-Defined Networking and programmable data planes, powered by the P4 language and FPGA-based platforms, offer dynamic network customization that can be used to implement resilient networks. With their high performance and programmability, FPGAs present cost-effective alternatives for diverse network applications, including offloading packet processing from servers. This paper introduces a configurable FPGA-based data plane implementing the Access Gateway Function (AGF). It offers a resilient operating mode to enhance network reliability and availability. The paper leverages the P4 language and the VitisNetP4 Intellectual Property to create RTL streams, enabling AGF on a pure FPGA target. The reported experimental results demonstrate that the proposed architecture can support 50K user flows with a resource utilization lower than 15% of that available in an Ultrascale+ FPGA (xcu280-fsvh2892-21-e). This leaves massive logic resources available to incorporate fault mitigation techniques and spare streams needed to enhance resiliency. Moreover, the presented workflow maintains an average latency of approximately 9 microseconds for each downstream or upstream packet.

Compact NSGA-II for Multi-objective Feature Selection

Compact NSGA-II for Multi-objective Feature Selection

Feature selection is an expensive challenging task in machine learning and data mining aimed at removing irrelevant and redundant features. This contributes to an improvement in classification accuracy, as well as the budget and memory requirements for classification, or any other post-processing task conducted after feature selection. In this regard, we define feature selection as a multi-objective binary optimization task with the objectives of maximizing classification accuracy and minimizing the number of selected features. In order to select optimal features, we have proposed a binary Compact NSGA-II (CNSGA-II) algorithm. Compactness represents the population as a probability distribution to enhance evolutionary algorithms not only to be more memory-efficient but also to reduce the number of fitness evaluations. Instead of holding two populations during the optimization process, our proposed method uses several Probability Vectors (PVs) to generate new individuals. Each PV efficiently explores a region of the search space to find non-dominated solutions instead of generating candidate solutions from a small population as is the common approach in most evolutionary algorithms. To the best of our knowledge, this is the first compact multi-objective algorithm proposed for feature selection. The reported results for expensive optimization cases with a limited budget on five datasets show that the CNSGA-II performs more efficiently than the well-known NSGA-II method in terms of the hypervolume (HV) performance metric requiring less memory. The proposed method and experimental results are explained and analyzed in detail. © 2023 IEEE.

Due to the enrolment of a very high number of students to programming modules, marking of programming modules is becoming a very tedious and time-consuming process. Programming assignments mainly test for the student's ability to think logically and approach a solution to the problem. In that case, just running the script and checking the output will not be sufficient enough to award a grade to the student. Marking criteria of programming modules provide certain marks for programs which are not syntactically correct but still have a good approach. Therefore, the code has to be read line by line and the implementation should be checked carefully to provide marks. Source code analysis has become mandatory in the current scenario. This leads to immense pressure and heavy workload on the staff who mark these programs. Considering all these aspects manual marking can lead to inconsistency, biasness, waste of time and less accuracy. Therefore, the main objective of this research is to minimize these problems by implementing an automated programming module marking tool by converting source codes to parse trees, extracting features, generating feature vectors, comparing them and generating a mark along with a feedback and plagiarism report. The solution focuses on automation marking by source code analysis and plagiarism checking. © 2022 IEEE.

The Internet of Things (IoT) connects numerous intelligent devices providing security features that interact with default settings accessed through applications. Additionally, Deep Learning (DL)-based mechanisms was involved for malware detection to identify and mitigate attacks. The Adaptive Synthetic Sampling (ADASYN) technique addresses class imbalances, especially when splitter class instances are distributed data in complex patterns. The proposed Self-Attention based Long Short-Term Memory (LSTM) classification method facilitates the handling of long-range dependencies in transferred data sequences offering high flexibility and adaptability to varying input lengths. For feature selection Particle Swarm Optimization (PSO) is utilized iteratively optimizes a solution in a high-dimensional space although it may have a low convergence rate due to its iterative process. The obtained results demonstrate the proposed Self-Attention based LSTM model achieves better accuracy reaching 98.05% on the NSL-KDD dataset and 99.01 % on the UNSW-NB15 dataset. These results ensure accurate classification compared to other existing methods, such as Convolutional Neural Network (CNN) and Recurrent Neural Network (RNN). © 2024 IEEE.

In order to achieve the goal that the manipulator can automatically obtain any position within its working range, and can adjust the end actuator for grasping, a machine vision sorting system is designed. The system passes through image processing, target recognition and positioning, and finally realizes the sorting effect through end control. The collected image information is processed by MATLAB. The image preprocessing adopts median filtering, image enhancement, binarization and edge detection. For the detection of workpiece surface defects, the improved segmentation network method of convolution neural network is adopted. In the algorithm of identifying workpiece type, the template matching method of log polar coordinate and Fourier transform is adopted. In the algorithm of workpiece position, the centroid of the workpiece is extracted as the positioning reference coordinate, combined with the three degree manipulator, the kinematics model of the manipulator is established. In the algorithm of workpiece grasping, the joint angle of each manipulator is obtained by inverse operation according to the position coordinates of the workpiece, and sent to STM32 through the serial port. Then the STM32 completes the control command to grasp and place the workpiece and complete the sorting task. The experimental results show that the system meets the design requirements. © 2022 IEEE.

Skin cancer is an abnormal growth of epidermal cells that can spread over time. It can develop gradually and become death threatening if left untreated. Early detection and prevention are essential as it may prevent the cells from spreading. In this study, skin cell image data is used to classify Benign and Malignant cells using CNN models. The image dataset goes through several data preprocessing techniques before being applied to achieve the most efficient outcome from four pre-trained CNN models. The pre-trained models used in the study are InceptionV3, MobileNetV2, VGG19, and EfficientNetB7. With the advancing epoch, an increase in accuracy is observed from the models. The highest accuracy of InceptionV3, MobilenetV2 and VGG19 is 89.86%, 83.06% and 77.5%, respectively, whereas EfficientNetB7 comes with a significantly lower accuracy score of 49.03%. The domination of InceptionV3 over all other models is observed in Precision, Recall and F1-Score while classifying skin cancer cells. © 2022 IEEE.
