However, the amount of such techniques has been less prominent for printed goods. The data hiding method presented in this paper is suited for the print domain. The method uses the Discrete Fourier Transform to embed data into images and Gray Component Replacement to maintain high image quality by masking embedding artifacts. This research examines whether the method's performance can be optimized using low-frequency ranges for embedding. The aim is to evaluate the usage of low-frequency ranges in order to achieve higher robustness. Different frequency ranges are tested to determine how they affect image quality and detection rates. Tests are conducted in the digital domain. The results show that the method can maintain image quality regardless of the frequency range, and that low-frequency ranges lead to more consistent detection rates. Future research will be done on images in the print domain.","PeriodicalId":432255,"journal":{"name":"Int. J. Softw. Sci. Comput.

The purpose of this study is to improve our understanding of what conditions prevent these projects from not being implemented. Using a qualitative methodology, based on case studies, the authors studied projects that have been implemented and others that have remained pilots to compare what factors determine the real implementation. Four conditions emerge from the analysis that seem to have a great influence on their implementation: technological anxiety, facilities (specifically changes in developments), training, and social influence, particularly when training is given by health professionals who are part of the pilot project to other colleagues. This work highlights a set of actions that should be implemented in eHealth innovation projects and also provides a basis for defining strategies to reduce the risk of increasing the phenomenon of plague of pilot, increasing the success rate in the implementation of the projects.","PeriodicalId":432255,"journal":{"name":"Int.

To shatter these limits, a smart learning assistant based on Wechat Mini Program is proposed that incorporates a score ranking mechanism based on explainable machine learning to improve learning interests in programming, a learning material recommendation with deep neural networks to solve the student's confusion in personalized learning source selection, and a learning review mechanism based on deep learning achievements to enhance teacher-student communication and student-student cooperation in learning. In addition, approximately 3200 learners are involved to investigate learning requirements and test system performance.

However, the existing loan question answering (QA) platforms cannot solve this problem well because of their poor understanding ability. Therefore, the authors constructs a loan QA platform based on ERNIE and knowledge graph (KG). Firstly, they use semi-automatic methods to construct KG with data from a loan company. Secondly, they use token-level random mask strategy (TRM), word-level fixed mask strategy (WFM), and fine-tuning strategy integrating knowledge (IK) to train ERNIE. Finally, they construct a QA platform based on KG and trained ERNIE and experiment with proprietary datasets. The results show that ERNIE trained after three strategies achieve average improvements of 14.7% on judging intention similarity of sentence pairs and 14.28% on retrieving the most similar intention problem compared with the baseline. It also shows that their platform achieves an average improvement of 13% on question answering compared with the customer service app of the loan company.","PeriodicalId":432255,"journal":{"name":"Int.

Institutions use the WeChat platform to attract users, but how to identify high-quality users has always been a difficult point for enterprises. In this paper, researchers proposed a classification algorithm based on SMOTE and the improved AdaBoost, which fuses feature information weights and sample weights to effectively solve the problems of overfitting and sample imbalance. To justify the study, it was compared with other traditional machine-learning algorithms. The accuracy and recall of the model increased by 19% and 36%, respectively, and the AUC value reached 0.98, indicating that the model could effectively identify the user's purchase intention. The proposed algorithm also ensures that it works well in spam identification and fraud detection.

However, the facial images of students collected in real classroom scenes often have problems, such as front and rear occlusion, blurred images, and small targets. Moreover, the current students' classroom expression recognition technology faces several challenges as a result of sample uncertainties. Therefore, this paper proposes an optimization algorithm for the uncertainties based on SCN. The correction weight of the sample through the sample weight was calculated, and the loss function was designed according to the correction weight. The dynamic threshold is obtained by combining the threshold in the noise relabeling module and the correction weight. The experimental results on public datasets and self-built classroom expression dataset show that the optimization algorithm effectively improves the robustness of SCN to uncertain samples.","PeriodicalId":432255,"journal":{"name":"Int.

The context-awareness of the supporting computers stems from the data acquisition of the occurring events at home. In some cases, different sensors provide input of identical type, thereby raising conflict-related issues. Thus, for each type of input data, fusion methods must be applied on the raw data to obtain a dominant input value. Also, for diagnostic inference purpose, data fusion methods must be applied on the values of the available classes of multiple contextual data structures. Dempster-Shafer theory offers the algorithmic tools to efficiently fuse the data of each input type or class. The employment of threading technology accelerates the computational process and carrying out benchmarks on publicly available data set, is shown to be more efficient. Thus, threading technology proved promising for home UbiHealth applications by lowering the number of required cooperating computers.","PeriodicalId":432255,"journal":{"name":"Int. J. Softw. Sci.

Existing sensor-based HAR systems have limited training data availability and lack fast and accurate methods for robust and rapid activity recognition. In this paper, a novel hybrid HAR technique based on CNN, bi-directional long short-term memory, and gated recurrent units is proposed that can accurately and quickly recognize new human activities with a limited training set and high accuracy. The experiment was conducted on UCI Machine Learning Repository's MHEALTH dataset to analyze the effectiveness of the proposed method. The confusion matrix and accuracy score are utilized to gauge the performance of the presented model. Experiments indicate that the proposed hybrid approach for human activity recognition integrating CNN, bi-directional LSTM, and gated recurrent outperforms computing complexity and efficiency.

It is quite helpful in connecting people. It has many advantages and some disadvantages too. Currently, in social media, hate and aggression have become a huge problem. On these platforms, many people make inflammatory posts targeting any person or society by using code mixed language, due to which many problems arise in the society. At the current time, much research work is being done on English language-related social media posts. The authors have focused on code mixed language. Authors have also tried to focus on sentences that do not use abusive words but contain hatred-related remarks. In this research, authors have used Natural Language Processing (NLP). Authors have applied Fasttext word embedding to the dataset. Fasttext is a technique of NLP. Deep learning (DL) classification algorithms were applied thereafter.
