2024Tzu-Chia Chen, Text Mining Techniques and Natural Language Processing, Text mining is an important branch of data mining that is used to analyze the text data. Text data is any type of data like structured data, unstructured data, and semi-structured data. All types of data are collected from different sources such as multimedia applications, mobile apps, digital systems, etc. These data are beneficial to get a good insight, meaningful results. We use data mining techniques like Support Vector Machine (SVM), Random Forest (RF), Multilayer Perception (MLP), Naive Bayes (NB), etc. to analyze the hidden relationship between data. We use three kinds of data types in text mining., John Wiley & Sons
2023Chen, Tzu-chia, Towards Applicability of Machine Learning in Business Analytics for Sales Prediction, In the field of data processing and analytics, machine learning has emerged as a topic of significant interest in the recent years. When it comes to decision-making, less structured retailers rely on their gut feeling, whereas more structured retailers make use of business intelligence. Predicting future retail sales is a common practise in the industry of organised retail, where it is tremendously helpful for making timely and strategic decisions in the face of intense competition. Predictions about future sales are often arrived at by doing an analysis of previous data, making use of a variety of statistical and mathematical methodologies, etc. This study is an endeavour to communicate with retail business owners, managers, and policymakers the accuracy of data derived from retail sales forecasting using machine learning algorithms. In this study, we apply the machine learning techniques known as Artificial Neural Network and Random Forest to a dataset that is often used for training purposes., CRC Press
2023Chen, Tzu-chia, Optimized Support Vector Machine for Early and Accurate Heart Disease Detection, Many academics use data mining to predict diseases. Some approaches can predict one sickness, while others can predict several. Sickness prediction may be improved. This article provides an overview of the numerous data categorization methods available today. Algorithms represent most commonly. Classifying data involves a lot of computation. To create a disease-fighting plan that works, enormous amounts of data must be analysed. Early diagnosis, severity assessment, and prognosis are frequent. Doing so may postpone disease development, improve quality of life, and lower medical costs. This approach uses machine learning. This article classifies and predicts cardiovascular disease data using machine learning. SVM, ANN, and RF classify heart disease data. Accuracy-wise, SVM is better for heart disease classification and detection., CRC Press
2023Chen, Tzu-chia, Conversational Artificial Intelligence-Ch29, In this day and age of smartphones and computers, the prevalence of mobile applications has skyrocketed. They have numerous applications, including but not limited to communication, social media, news, messaging, shopping, making payments, watching videos and transmissions, and engaging in online gaming. When it comes to mobile devices, Android is presently the operating system with the most users worldwide. The Android platform has emerged as the most popular mobile operating system, with an increasing number of applications developed especially for Android mobile devices. Simultaneously, there has been a rise in the number of incidents. Attackers exploit vulnerable areas in mobile apps to introduce potentially malicious code into the system and steal confidential data. When creating an app for a mobile device, it is critical to prioritize the security and protection of users’ data. Only by thoroughly understanding the various vulnerabilities that could be introduced into their code can mobile app developers successfully fight potential security threats. This manuscript provides an in-depth study of vulnerability assessment and penetration testing in mobile applications. This manuscript also presents a mitigation plan for encountering vulnerabilities in mobile applications. A security framework is also proposed to enhance the security of mobile applications., John Wiley & Sons, Inc.
2023Chen, Tzu-chia, Conversational Artificial Intelligence-Ch20, An intrusion detection system, often known as IDS, is primarily used to gather and analyze data regarding security events that occur in computer systems and networks. Its subsequent purpose is to either prevent these events from happening or notify them to the administrator of the system. As a result of the increasing number of attacks carried out by attackers, the users’ level of mistrust on the Internet has increased. Attacks that cause denial of service are a major violation of security. This article presents a particle swarm optimization and AdaBoost-based intrusion detection system. In this system, chatbot receives network traffic as input, and features of input dataset are selected using particle swarm optimization algorithm. A classification model is trained and tested. AdaBoost, KNN, and naïve Bayes algorithm are used to classify and detect malware-related records. NSL KDD dataset is used in the experimental work. PSO-AdaBoost achieves the highest accuracy, precision, and recall for intrusion detection and classification. The output of a chatbot is a language that is either normal or benign., John Wiley & Sons, Inc.
