It is argued that for analysis of Positive Unlabeled (PU) data under Selected Completely At Random (SCAR) assumption it is fruitful to view the problem as fitting of misspecified model to the data. Namely, it is shown that the results on misspecified fit imply that in the case when posterior probability of the response is modelled by logistic regression, fitting the logistic regression to the observable PU data which does not follow this model, still yields the vector of estimated parameters approximately colinear with the true vector of parameters. This observation together with choosing the intercept of the classifier based on optimisation of analogue of F1 measure yields a classifier which performs on par or better than its competitors on several real data sets considered.

In an era when healthcare was becoming increasingly crucial, many developing nations, including Yemen, struggled to provide basic medical services. Nearly half of Yemen's population lacked access to adequate healthcare, with the situation being even more dire in rural and remote areas. While sectors such as industry, agriculture, and environmental science rapidly embraced technological advancements, healthcare systems in these regions lagged, with limited research addressing affordable and accessible solutions. This gap was further highlighted by the global healthcare crisis and the urgent need for innovative, cost-effective approaches. In response, this study outlined the creation and deployment of a cost-effective health monitoring system utilizing Internet of Things (IoT) technology to address these challenges. The system was designed to monitor vital signs, specifically heart rate (HR), using an Arduino Uno and ECG sensor, at a meager total cost of $27.25. It provided real-time monitoring for situations requiring immediate intervention. Power consumption tests demonstrated that the system operated efficiently, consuming between 1.061 and 1.35 watts, making it practical and affordable. Additionally, the potential integration of deep learning techniques promises to enhance the system's accuracy and efficiency. Although this study focused on IoT-based health monitoring, its potential extended beyond this, offering broader implications for future healthcare technology solutions.

Accuracy in training sentiment analysis models for large number of review datasets is affected by the correct classification of sentiment labels. Improving the accuracy of sentiment labels, and text representation also affects the performance of sentiment analysis models. Deep learning methods have been widely used to solve various sentiment analysis problems. To improve the performance of deep learning in sentiment analysis, it is necessary to use the right labeling method and good text representation to be used as an embedding layer. This study proposes sentiment labeling using Lexicon and Long Short-Term Memory (LSTM) as well as used FastText as embedding words in sentiment classification. As a corpus, the InSet Lexicon Dictionary is employed for feature extraction. The sentiment data used is the reviews given by users on several applications provided on Google Play. The results showed that the LSTM network using Word-embedded FastText with a dimension of 300 words received a small error value of 0.111 with an accuracy of 95.55% for data labeled based on Lexicon.

As diverse as software project stakeholders are, so are their project needs and interests. Furthermore, the criteria to measure project success are based on the stakeholder groups’ various needs. It is on the basis of these diverse measurement criteria that project success has become an elusive moving target. Despite this, the measurement and achievement of project success remains a critical milestone in project management for the satisfaction of stakeholders, including software project teams (SPTs). Several research studies have reported project success or failure from various stakeholders’ perspective. However, recent studies have projected SPTs as the most neglected key stakeholder group by software project managers and researchers in the project management field. Given this backdrop, conducting a systematic literature review (SLR) research study to determine if there are empirical studies that have evaluated software project success from SPTs’ perspective would be of interest to many in the field. According to the study's authors there is no study that has been conducted to determine this. The study found one (1) paper, which evaluated a project based on the SPTs’ success criteria, thus showing a research gap and indicating the neglect of this group of stakeholders when it comes to establishing whether software projects meet their needs or not. This study recommends that empirical studies be conducted to close this research gap.

The skin is the outermost part of the body that is sensitive to external stimuli. One of the skin diseases that can be transmitted is herpes. Belated in understanding herpes skin disease can be fatal to sufferers because herpes disease that is too late to be treated can affect more serious diseases. Therefore, we need a mobile-based application that can identify the infectious skin disease herpes. An expert system is one of the fields of science that can solve a problem in a system. The expert system has several methods that can be used, namely case-based reasoning (CBR) and rule-based reasoning (RBR) methods. CBR can be used to solve a new problem by utilizing previous problems and RBR is a method that can be used to solve a problem using a rule base, where each rule is obtained from experts and literature studies. By applying the combination method of CBR and RBR which can be used to diagnose herpes skin disease, it is hoped that it will prevent the spread of herpes disease from spreading.
