In the ever-changing world of digital communication, the proliferation of code-mixed languages raises new challenges for content classification, particularly in the context of spam identification. SMS ( Short Message Service) is a popular form of communication, but there are security flaws in it, such as an increase in spam from online fraudsters. This research aims to develop an ensemble of machine-learning models that can classify Bangla-English code-mixed SMS as spam or ham. Our method, which uses a large dataset of code-mixed SMS, includes several classification algorithms, including Logistic Regression, Support Vector Machines, Random Forests, and Multi-Layer Perceptron Classifier (MLPC). To increase the robustness of our model, we employ feature extraction techniques such as TF-IDF for code-mixing scenarios. The ensemble technique employs a voting procedure to integrate individual model predictions, enhancing accuracy while minimizing the risk of misclassification. The experimental results reveal that our ensemble model outperforms single classifiers, with a 96.92% accuracy and high recall and precision metrics. This study enhances the science of natural language processing and has practical implications for SMS filtering systems in multilingual settings, hence boosting user experience and security in digital communications.

Deep convolutional neural network (DCNN) image analysis improved plant health management. DCNN methods require train samples with diverse feature distribution and discriminative features for the models to generalize well on unseen categories. The limited train sample coined with the locality nature of the convolution operator and commonly shared kernel weights led CNN models to a sub-optimal solution. To address these challenges, we trained a multi-head self-attention augmented CNN (AAC) and explored other attention augmented networks to jointly exploit global salient and local shared features for fine-grained plant disease classification and visualization. We further proposed stochastic train sample transformations to enlarge and improve train sample diversity and feature distribution. The experiment evaluations on the PlantVillage dataset confirmed that the attention augmentation methods demonstrated robust performance in disease classification and visualization. Specifically, the AAC network scored 99.56% with stochastic transformed train samples, 98.01% with simple geometric transformed samples, and 97.34% without transformation. Therefore, attention augmentation in general, AAC in particular, and stochastic sample transformation can address discriminative plant disease classification and visualization.

Vehicle Edge Computing (VEC) is the deployment of applications close to edge servers to provide low latency and highly responsive services to users. However, due to the complexity and dynamics of the VEC environment, it is prone to errors and failures, and the reliability of edge service migration may be compromised if no measures are taken to cope with different levels of failures. To address this issue, this paper proposes an modified (m, n)-fault tolerance strategy (M-MNFT). Unlike the traditional one, which only considers ES failures, M-MNFT additionally selects redundant edge base stations to ensure task reliability during task migration, and takes into account the fact that the relative distance between the request and the base station is as small as possible when the request is sent, so as to avoid the impact of the edge base station failure on the Quality of Service (QoS) during task migration. In addition, we have performed extensive simulations to show that M-MNFT outperforms existing methods in terms of the number of delayed requests, on-time finish rate, and average waiting time.

With the advancement of technology, e-learning has emerged as predominant in the education sector. As students, parents, and educators acknowledged, adopting e-learning can offer several benefits over traditional learning techniques. Since more individuals are becoming acclimated to online learning platforms, these online platforms can provide a simple, instructive, and efficient mode of delivery. This novel approach could be improved with the aid of Artificial Intelligence (AI) to comprehend consumers more thoroughly and provide valuable and better-suited services. Most sectors in education, including universities, swiftly adapted to new educational methodologies because of their flexibility and productivity. Nevertheless, there are some downsides that young demography experiences, such as less instructiveness, distraction due to the absence of teachers, and poor IT literacy. Consequently, these drawbacks would recede the capability of students to assimilate content during the lecture. Therefore, the main objective of this research is to implement an E-learning platform with AI learning analytics to enhance students’ performance regularly while reducing the significant drawbacks of the E-learning platforms. This research consists of students’ focus detection, essay-based answer evaluation, note summarization, mind map generation, and personalized guidance facilities.
