Using Coevolution and Substitution of the Fittest for Health and Well-Being Recommender Systems

Abstract This research explores substitution of the fittest (SF), a technique designed to counteract the problem of disengagement in two-population competitive coevolutionary genetic algorithms. SF is domain independent and requires no calibration. We first perform a controlled comparative evaluation of SF’s ability to maintain engagement and discover optimal solutions in a minimal toy domain. Experimental results demonstrate that SF performs similarly to alternative techniques presented in the literature but has the advantage of requiring no parameter tuning. We then address the more complex real-world problem of evolving recommendations for health and well-being. We introduce a coevolutionary extension of EvoRecSys, a previously published evolutionary recommender system. We demonstrate that SF is able to maintain a better trade-off between engagement and performance than other techniques in the literature, and the resultant recommendations using SF are higher quality and more diverse than those produced by EvoRecSys.
Speech Style Analysis: Sociolinguistic Perspective

The prompt development of English has formed a new perception that English should be the language of daily life. Diverse studies have been carried out to extend knowledge about the language itself with the various methods used. The researcher, in this context, aims to examine the speech style used by the main actor and the racial conflict that happened in the movie of “Freedom Writer”. The researcher uses a socio-linguistic approach to get a better understanding of the context of the speech and the speech style that is used according to the context. The film was based on a real story that happened in the united stated. The film was released in 2007. The researcher found a variety of speech style that was used by the main actor in the movie. The most dominant speech style used in the film is “Formal Style”. The formal style is used in an important and serious situation such as lectures, sermons, television newscasts, and some other occasions. The language style that is rarely used in this film is the “Frozen” style because the style is used in certain literature. More complexed discussion in this movie regarding racial issues were also further discussed.
Influence of Spiritual Leadership on Green Creativity Mediated by Employee Environmental Commitment

Hybrid and Invisible Digital Image Watermarking Technique Using IWT-DCT and Hopfield Neural Network

According to the characteristic of HVS (Human Visual System) and the association memory ability of the neural network, an adaptive image watermarking algorithm based on a neural network is proposed invisible image watermarking is a secret embedding scheme for hiding secret images into a cover image file and the purpose of invisible watermarking is copyrights protection. Wavelet transformation-based image watermarking techniques provide better robustness for statistical attacks in comparison to Discrete Cosine Transform domain-based image watermarking. The joined method of IWT (Integer Wavelet Transform) and DCT (Discrete Cosine Transform) gives benefits to the two procedures. The IWT has an impediment of portion misfortune in embedding which increments the mean square estimate as SIM and results in diminishing PSNR. The capacity of drawing in is improved by pretreatment and re-treatment of image scrambling and Hopfield neural network. The proposed algorithm presents a hybrid integer wavelet transform and discrete cosine transform-based watermarking technique to obtain increased imperceptibility and robustness compared to the IWT-DCT-based watermarking technique. The proposed watermarking technique reduces the fractional loss compared to DWT-based watermarking.
Using Pearson Correlation and Mutual Information (PC-MI) to Select Features for Accurate Breast Cancer Diagnosis Based on a Soft Voting Classifier

Breast cancer is one of the most critical diseases suffered by many people around the world, making it the most common medical risk they will face. This disease is considered the leading cause of death around the world, and early detection is difficult. In the field of healthcare, where early diagnosis based on machine learning (ML) helps save patients’ lives from the risks of diseases, better-performing diagnostic procedures are crucial. ML models have been used to improve the effectiveness of early diagnosis. In this paper, we proposed a new feature selection method that combines two filter methods, Pearson correlation and mutual information (PC-MI), to analyse the correlation amongst features and then select important features before passing them to a classification model. Our method is capable of early breast cancer prediction and depends on a soft voting classifier that combines a certain set of ML models (decision tree, logistic regression, and support vector machine) to produce one model that carries the strengths of the models that have been combined, yielding the best prediction accuracy. Our work is evaluated by using the Wisconsin Diagnostic Breast Cancer datasets. The proposed methodology outperforms previous work, achieving 99.3% accuracy, an F1 score of 0.9922, a recall of 0.9846, a precision of 1, and an AUC of 0.9923. Furthermore, the accuracy of 10-fold cross-validation is 98.2%.

Exploring Job Application Letters of EFL Learners

The background to this analysis is that many companies require applicants to write their application letters in English. If a student wishes to get a job, a job application letter is required upon leaving school. The purpose of this study is to examine EFL learners’ application letters. This study uses a qualitative methodology and discourse analysis as its research design. The data used in qualitative research comes from a variety of application letters. Participants in this study were high school students at a vocational school. It consists of four students in grade 12—two boys and two girls. The research was conducted through an analytical process in which a student completed her application within one week. They are then collected and analyzed by researchers. The general structure of job application letters is analyzed, and formal and informal words in job application letters are recognized and noted. In general, the results of the above analyses show that two students met the criteria for writing a job application letter, while the other two students did not yet meet the criteria for writing a job application letter. Teachers should pay more attention to teaching writing subjects, especially in making sentences such as when writing a job application letter. If you find an error while writing, explain of the errors to avoid mistakes from happening again and reduce error at the start.

Marketing Overload: The Impact of Information Overload on Brand Recall (A Case Study of Students of the University of Swat)

Marketers promote their products using a different medium to circulate their advertising message to customers in order to inform and persuade customers to buy their products. The emergence of new technology and social media platforms has made it much easier for marketers to reach more audiences than ever before. This excessive advertisement has emerged as a new phenomenon known as infobesity, advertising overload, or marketing overload. The purpose of this study is to find out the effect of Information overload on brand recall, for which a quantitative method was used with a sample size of 148 students and SPSS 21 for analysis of the data. The survey was conducted, and questionnaires were distributed among the students of the University of Swat. The study reveals that a negative and significant relationship exists between information overload and brand recall. This study also reveals that excessive bombardment in advertisements results in a decline in the effectiveness of the advertising message and goes against brand awareness and brand recall. The correlation analysis (r= -0.353, P&lt;0.05) and regression analysis (beta = -0.415, P&lt;0.05) reveal that information overload negatively impacts customer brand recall.
