    The Internet of Things (IoT) is revolutionizing healthcare and driving the creation of smart e-health monitoring solutions. Since IoT devices create a lot of data, this evolution depends on providing stakeholders and patients with real-time updates. With new technologies emerging to securely manage health data, technology is essential to modern healthcare monitoring. There are two main types for health data: unstructured data is more diverse and includes things like emails and media content, while structured data follows certain guidelines. Meeting strict security criteria is crucial for utilizing data from these devices in real-time applications. Because the Internet of Things generates a significant amount of data that needs to be analyzed with specialized tools, it is imperative to store data in a secure environment. The creation of an intelligent e-health monitoring system is the main objective. This system gathers health data from several sensors, integrates the data, and filters pertinent information about the patient's current condition. The proposed system also describes an authorized architectural node within the IoT network and a secure platform for exchanging e-health data. For real-time applications, it is essential to ensure the security of data generated by Internet of Things devices. Because so much data needs to be processed, it is imperative that it be stored in a secure environment using specialized technologies. The major goal is to develop an intelligent e-health monitoring system that gathers health data from various sensors, integrates health status, filters pertinent patient data, and enables safe sharing within the Internet of Things

    Get PDF
    Implementing artificial intelligence, specifically deep learning algorithms, to enhance agricultural productivity is a great initiative, especially in a country like India where agriculture is a crucial sector. Using TensorFlow and Keras for this purpose provides a solid foundation, given their popularity and extensive documentation. Using deep learning to identify and classify cowpea leaves can indeed streamline various agricultural processes, such as monitoring plant health, pest detection, and yield estimation. The utilization of YOLOv5, a CNN-based architecture, for the binary classification of cowpea leaves against other leaves like mangoes is a smart choice. Transfer learning can further optimize this model by leveraging pre-trained weights from similar tasks, which can significantly reduce the computational resources and time required for training. As you proceed with this experiments and model development, ensure robust data collection and preprocessing, as the quality of input data greatly influences the performance of deep learning models. Additionally, consider integrating techniques for data augmentation to further enhance the model's generalization capabilities. Continued research and development in this area can lead to significant advancements in agricultural practices, ultimately benefiting farmers and contributing to food security

    The COVID-19 pandemic has intensified the need for innovative, scalable diagnostic tools for mental health, given the surge in related disorders globally. This study presents a novel neural symbolic approach leveraging natural language processing (NLP) to analyze semantic coherence in text data, aimed at predicting mental health outcomes. Integrating convolutional neural networks (CNNs) with long short-term memory networks (LSTM) and an attention mechanism, this model excels in extracting and emphasizing critical linguistic features from vast datasets of online textual communications. Our evaluations show that the model achieves an accuracy of 92.4%, with precision, recall, and an F1-score significantly superior to traditional LSTM models. The ROC-AUC score of 0.92 highlights its effectiveness at distinguishing various mental health states, while the attention mechanism enhances the model’s interpretability, shedding light on key text features indicative of mental distress. This research underscores the potential of AI in enhancing mental health diagnostics in the context of current events, proposing a powerful tool for early detection and intervention

    A MACHINE LEARNING APPROACH TO ASSESS PSYCHOLOGICAL STATE AMONG UNIVERSITY STUDENTS THROUGHOUT THE COVID-19 PANDEMIC: BANGLADESH PERSPECTIVE

    Get PDF
    The COVID-19 outbreak in Bangladesh had a negative impact on people of all ages. The epidemic's destruction clearly had an effect on people's mental health, especially that of university students. From the beginning of the pandemic in Bangladesh, educational institutes were shut down, complete lockdown condition, unable to get sports and entertainment abilities, which caused the student's psychological health to suffer. Most university-aged students exhibited long-lasting psychological issues corresponding with COVID-19, including significant levels of stress, anxiety, and depression. Predicting the psychological state will indicate a lack of psychological resilience, which will be associated with mental health problems among Bangladeshi university students. Increasing psychological fortitude is essential to ensuring pupils' well-being throughout the epidemic. Through an online survey and several machine learning algorithms, our system predicts the psychological state of Bangladeshi university students. We preprocessed this dataset by cleaning it correctly for the procedure. We utilized hyper-parameter tweaking to extract the features, and then we trained the dataset using a number of classifiers, such as the support vector classifier, random forest, logistic regression, decision tree, naive Bayes, KNN, and gradient boosting. Study suggests that, these algorithms works best in researching on mental health related datasets. Among these several machine learning algorithms, our created dataset of  509 points, comprising support vector classifier (SVC), produced an AUROC score of 0.98, 0.97, and 0.97 for depression, anxiety, and stress states, respectively. Additionally, SVC also delivered respectable outcomes on the open-source dataset we collected for each of the psychological states - depression, anxiety, and stress. Support vector machine (SVM), a supervised machine learning model that employs classification methods, may, in general, produce excellent results when there is a distinct proportion of displacement between classes. By evaluating a dataset we have collected and enhancing the DASS-21 formulation to measure an individual's depression, anxiety, and stress. DAAS-21 is well established screening method for addressing mental health issue. We sincerely considered the ethics and all the data we collected from people are preserved with care and utmost privacy. This study will aid in the growth of research into the area of suicidal thoughts and emotional states
