Most machine learning tasks fail to work properly with an imbalanced dataset. There exist various approaches to balance a dataset, but suffer from issues such as overfitting and information loss. This manuscript proposes a novel and improved cluster-based undersampling method for handling two and multi-class imbalanced dataset. Ensemble learning algorithm integrated with the pre-processing technique is used to address the class imbalance problem. The proposed approach is tested using a publicly available imbalanced Google cluster dataset, in case of imbalanced dataset the F1-score value for each class has to be checked, it is observed that the existing approaches F1-score for class 0 was not good, whereas the proposed algorithm had a balanced F1-score of 0.97 for class 0 and 0.96 for class 1. There is an improvement in F1-score of about 2% compared to the existing technique. Similarly for multi-class problem the proposed novel algorithm gave balanced AUC values of 0.87, 0.83 and 0.97 for class 0, class 1 and class 2 respectively.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135649643","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}

WSNs are implemented to monitor temperature, humidity, and pressure, among others within the agricultural environment. This paper addresses the traffic congestion that occurs within WSNs in the agricultural environment during packet transmission that is normally caused by head-of-line blocking. As a result, packet loss, packet delay, and network performance impairment occurred during packet distribution in the network. This paper proposed an Intelligence Traffic Routing (ITR) algorithm to manage packet flow to avoid traffic congestion in WSNs within the agricultural environment while improving Quality of Service (QoS). The LBRM (Load Balancing Routing Management) and MLCC (Machine Learning Congestion Control) algorithms were integrated to develop the proposed ITR algorithm. Network Simulator 2 (NS-2) was used to test the effectiveness of the proposed ITR algorithm. The simulation results showed that the proposed ITR algorithm reduced packet loss by 27.3%, packet delay by 43.4%, and improved network throughput by 98.4% when compared with LBRM and MLCC algorithms.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66330051","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}

The first one is commonly used to allocate an image’s pixels into distinct clusters. However, the allocation of these pixels is not optimal in all cases. The second technique is usually employed to produce an optimal watermarking solution. In this paper, a hybrid methodology is presented for coloured image watermarking that integrates both genetic algorithm and k-means clustering activity to attain the optimized cluster centroids. These centroids are utilized to optimally distribute the pixels of the cover and watermark images into suitable clusters. This will help decrease the perceptible changes in the watermarked image with the naked eye. For concealment, the Least Significant Bits method is adopted. Typically, the pixels of every watermark cluster are concealed in its closest cover’s cluster; wherein every two successive pixels hide the bits of a single cover image’s pixel. The experimental results demonstrate that the proposed methodology satisfies a sufficient imperceptibility that yields and boosts resistance against common attacks.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66330144","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}

Farmers, however, have a complicated and time-consuming task in detecting and categorizing insects. Therefore, research on an effective system for image-based automated insect classification is crucial. The conventional “softmax” function is utilized to determine the category for new image occurrences and minimize “cross-entropy” loss in the bulk of current research, which focuses on employing deep convolutional neural networks to categorize insect images. This paper presents a novel method for large-scale insect pest image classification by combining fine-tuning EfficientNets and Power Mean Support Vector Machine (SVM). First, EfficientNet models are fine-tuned and re-trained on new insect pest image datasets. The retrieved features from EfficientNet models are then utilized to create a machine learning classifier. In the network’s classification stage, the traditional “softmax” function is substituted with a non-linear classifier, Power Mean SVM. As a result, rather than “cross-entropy loss,” the training process focuses on reducing “margin-based loss.” Several benchmark insect image datasets were used to evaluate our proposed method. According to the numerical results, our method outperforms other cutting-edge methods for large-scale insect pest image categorization. With fine-tuning EfficientNets and Power Mean SVM, the classification accuracy of the proposed method for the Xie24, D0, and IP102 large insect pest datasets is 99%, 99%, and 72.31%, respectively. To our knowledge, these are the best performing image classification results for these datasets.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66330364","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}

It combines the Long Short-Term Memory (LSTM) with factors that influence the price of crude oil. The information from fundamental and technical indicators is considered along with statistical model predictions like autoregressive integrated moving average (ARIMA)to make one-step-ahead crude oil price predictions. A Principal Component Analysis (PCA) approach is employed to transform the explanatory variables. This study combines the LSTM with PCA, jointly known as the LP model wherein PCA transforms of the fundamental and technical indicators are used as inputs to improve LSTM predictions. Further, it attempts to improve these predictions by introducing the LSTM+PCA+ARIMA (LPA) model, which uses an ensemble learning approach to utilize the forecast from the ARIMA model, as an additional input. Among LP and LPA models, the LSTM model is used as a benchmark to evaluate the performance of the hybrid models. Based on the result, a significant improvement is seen in the LP model over the chosen window sizes and error metrics. On the other hand, the LPA model performs better across all dimensions with an average improvement of 41% over the LSTM model in terms of forecasting accuracy. Moreover, the equivalence of forecasting accuracy is tested using the Diebold-Mariano and Wilcoxon signed-rank tests","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66330629","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}

Generally speaking, multimedia applications operate by performing repeated arithmetic and table-lookup coding operations. Therefore, to make it easier to achieve those required high levels of performance, versatility, and programmability, we propose an accelerator for mobile Central Processing Units (CPUs) known as a Content Addressable Memory-based massive-parallel Single Instruction Multiple Data (SIMD) Matrix Core (CAMX) that improves the processing speeds of both arithmetic and table-lookup coding operations. Our proposed CAMX, which is equipped with two CAM modules, has highly parallel processing capabilities that facilitate fast table-lookup coding operations. In fact, the results of Advanced Encryption Standard (AES) encryption simulations conducted in this study show that its AES encryption total clock cycles are 1,362,699. Additionally, a detailed breakdown of the number of clock cycles shows 1,312,160 for SubBytes, a combined total of 17,161 for ShiftRows and MixColumns, and 2519 for AddRoundKey. This paper also confirmed that CAMX could process AES encryptions at a rate of 83.17 clock cycles/byte. Also, the performance of CAMX, related works, and existing mobile processors are compared. The related works do not have a dedicated circuit for AES processing. From the comparison results, CAMX provides a performance improvement of approximately 4.4-and 3569.1-times over the related works. The existing mobile processors are Texas Instruments (TI) DM3730 and a TI OMAP3530. From the comparison results, CAMX provides a performance improvement of approximately 2.1 times over TI DM3730 and TI OMAP3530.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66330890","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}

With high incidence and mortality rates, it is ranked as the primary and most significant health hazard for women globally. Early detection of the disease is the key to ensure the survival of the patient. Several medical techniques comprising of Mammography, Magnetic Resonance Imaging, Thermography and many more are available to detect the disease. But these techniques create much stress and pain, besides employing harmful rays for detection, to the patient undergoing them. Hence for early detection other categories of techniques can be implemented. Machine-learning assisted detection and classification is one such alternative. In this paper a hyper parameter optimized extreme gradient boosting model implemented along with F-Score feature selection is proposed and the model is used for classification of the breast tumor as either malignant or benign on the Wisconsin Breast Cancer dataset. The implementation of feature importance is investigated using F-Score and this is used for selecting the most relevant features that influence the target variable and classification is based on this. Experimentation is done using different training-testing partitions and the best performance of 99.27% accuracy score was shown by the 80−20 partition by the proposed XGBoost and F-Score Model.","PeriodicalId":36452,"journal":{"name":"Journal of Advances in Information Technology","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66331041","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}
