A Supervised Learning-Based Framework for Predicting COVID-19 in Patients

The integration of ML and loT can provide insightful details for critical decision making, automated responses, etc. Predicting future trends and detecting anomalies are some of the areas where loT and ML are being used at a rapid rate. Machine learning can help decode the hidden patterns in IoT data. It may complement or replace manual processes in critical areas with automated systems that use statistically derived behavior. In healthcare, wearable sensors used for tracking patient activity have been continuously producing a staggering amount of data. This paper proposes an IoT-based scalable architecture for detecting COVID-19-positive patients and storing and processing such massive amount of data on the cloud. The proposed architecture also employs machine learning algorithms for correct classification of patients. The proposed architecture employs gradient boosting classifier method for early detection of COVID-19 in the patient's body. In order to make the architecture scalable and faster in terms of computational power, the architecture employs cloud computing for data storage. © 2023 IGI Global. All rights reserved.

ILC-Unet++ for Covid-19 Infection Segmentation

Since the appearance of Covid-19 pandemic, in the end of 2019, Medical Imaging has been widely used to analysis this disease. In fact, CT-scans of the Lung can help to diagnosis, detect and quantify Covid-19 infection. In this paper, we address the segmentation of Covid-19 infection from CT-scans. In more details, we propose a CNN-based segmentation architecture named ILC-Unet++. The proposed ILC-Unet++ architecture, which is trained for both Covid-19 Infection and Lung Segmentation. The proposed architecture were tested using three datasets with two scenarios (intra and cross datasets). The experimental results showed that the proposed architecture performs better than three baseline segmentation architectures (Unet, Unet++ and Attention-Unet) and two Covid-19 infection segmentation architectures (SCOATNet and nCoVSegNet). © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

One solution to the system architecture for the acquisition of data obtained by monitoring computer users

In this paper, a possible solution for the architecture of the remote employee monitoring system is proposed. Development of such a system is particularly interesting at a time of the Covid-19 virus pandemic, when many employees work from home. Today's monitoring systems are mainly based on time tracking and screen monitoring features, without in-depth further analysis of the collected data. Therefore, the aim of this paper is to present one architecture solution that will support not only data collection, processing and visualization, but also the application of Machine learning algorithms that will perform more complex and deeper analyzes. As a result of this paper, the proposed architecture will provide a clear insight into the structure of the system, before the beginning of its development. © 2022 IEEE.

Design and Development of an Integrated Internet of Audio and Video Sensors for COVID-19 Coughing and Sneezing Recognition

There are a lot of ongoing efforts to combat the COVID-19 pandemic using different combinations of low-cost sensing technologies, information/communication technologies, and smart computation. To provide COVID-19 situational awareness and early warnings, a scalable, real-time sensing solution is needed to recognize risky behaviors in COVID-19 virus spreading such as coughing and sneezing. Various coughing and sneezing recognition methods use audio-only or video-only sensors and Deep Learning (DL) algorithms for smart event recognition. However, each of these recognition processes experiences several types of failure behaviors due to false detection. Sensor integration is a solution to overcome such failures. Moreover, it improves event recognition precision. With the wide availability of low-cost audio and video sensors, we proposed a real-time integrated Internet of Things (IoT) architecture to improve the results of coughing and sneezing recognition. Implemented architecture joins edge and cloud computing. In edge computing, the microphone and camera are connected to the internet and embedded with a DL engine. Audio and video streams are fed to edge computing to detect coughing and sneezing actions in realtime. Cloud computing, which is developed based on the Amazon Web Service (AWS), combines the results of audio and video processing. In this paper, a scenario of a person coughing and sneezing was developed to demonstrate the capabilities of the proposed architecture. The experimental results show that the proposed architecture improved the reliability of coughing and sneezing recognition in the integrated cloud system compared to audio-only and video-only detectors. Three factors have been considered to compare the results of the proposed architecture: F-score, precision, and recall. The precision and recall of the cloud detector are improved on average by %43 and %15, respectively, compared to audio-only and video-only detectors. The F-score improved on average 1.24 times. © 2021 IEEE.
