This research aims to propose an innovative smart system we developed for early failure detection of Automatic Tool Change (ATC) systems. Input data is the system's tool magazine door open/close signals. Then, 41 indicators from 26 machines are obtained from statistics-based feature extraction methods. Under the guidance of predefined risk levels, nine high-ranking top level indicators are selected using correlation and regression analysis. In addition, some lightweight supervised learning algorithms are used to build and train the model to solve the classification problem of the system states, such as Normal, Caution, and Danger. The experimental results confirm that the high-ranking indicators can achieve the most prominent and stable performance under a series of tests. Under 10-fold cross-validation, the average accuracy is 89.43 %, which is 19 similar to 38 % higher than those of other feature groups. Among them, the Naive Bayes algorithm obtains the best accuracy of 94.2 %. This proves that the proposed smart system can effectively grasp the health status of the ATC systems.

A motion adaptive algorithm for video de-interlacing is presented in this paper. It is based on a fuzzy inference system, which performs an interpolation between two linear techniques as a function of the motion level. Fuzzy systems with different number of 'if-then' rules have been analyzed and compared in terms of complexity as well as efficiency in de-interlacing benchmark video sequences.

The services and products of E-Commerce portals in this digital age are heavily reviewed by the users. These reviews provide useful insights on the quality/usage of these products. Due to such importance of reviews, they can be faked to give false opinions about products and subsequently mislead the users. In this paper we are proposing new set of lexical and syntactic features set and applying supervised algorithms for performing classification on fake reviews dataset (gold standard). We focus on the writing style, that include type of punctuation mark, Part-of- Speech (POS) etc., that are helpful for detection of reviews spam. The final results give promising accuracy 91.51% for detecting fake reviews.

This article presents the application of a new damage assessment method based on a supervised learning algorithm that uses the principle of maximum entropy. The proposed algorithm employs, as reference information, the natural frequencies and mode shapes obtained with a numerical model of the structure in an undamaged condition and under different damage scenarios. The algorithm is validated with experimental tests on a laboratory six-levels-structure that is 2 m tall. The structure was anchored to a horizontal vibrating shaker table and it was excited at the support level by different seismic records and colored noise. The change in the structure from a normal condition to a damaged one is made by three consecutive reductions in the cross-section of a column. Additionally, a perturbation is introduced as a 0.5 % increase in the total mass of the structure. The experimental modal properties are identified by the Stochastic Subspace and Multivariable Output Error State sPace (MOESP) methods and they are compared with those obtained with a numerical model. The identification, location and quantification of damage that has been obtained with the proposed algorithm in the different test conditions, agrees well with the experimental damage, even for the conditions were few sensors are located in the structure.

Online social networks (OSN) are one of the most widely adapted services of the Internet infrastructure, Facebook being one of the most popular among them. Facebook models connections between its users through the concept of "friendship". However, the type and intensity of these connections between different people on Facebook vary significantly. In most cases, friends on Facebook correspond to mere acquaintances in real-life, with only a smaller subset representing actual close friends. The aim of research presented in this paper is to provide a method for estimating the intensity of Facebook friendships, i.e., to distinguish connections representing close friends from others. The study was performed by analyzing Facebook interactions between users (e.g. number of mutual likes, comments, shared photos, etc.) using supervised learning algorithms for binary classification of data. Among the chosen algorithms, the best results were gained by using random forest algorithm - accuracy of 84.73%.

This research supports improved salesforce outcomes for companies with independent sales representatives via the application of emerging technologies. It is framed in expectancy theory (in: Vroom, Work and motivation, Wiley, New York, 1964), Herzberg's et al. (The motivation to work, Wiley, New York, 1959) two factor theory, and the job demands and resources model (JD-R) (Bakker and Demerouti in J Manag Psychol 22:309-328, 2007). The study analyzes the 2018 National Salesforce Survey (USA) commissioned by the Direct Selling Association (Washington, DC, USA). It identifies key factors in salesforce motivation and performance theories studied within these theoretical frames and channel-specific inputs for direct selling independent representatives. While researchers apply multiple methods to salesforce motivation and performance, the power of machine learning has not been applied to independent representatives and their unique circumstances. This research employs supervised learning algorithms for predictive analytics to create models for recruits and existing independent representatives. It finds that the most crucial factors align with expectancy theory for both. Allocated time for direct selling, ability to find new customers, gender, and adopting direct selling as a career play key roles in predicting sales success for individuals entering direct selling. The highest-performing representatives are characterized by time invested, experience of direct selling, recruitment, tenure, and use of technology. By predicting representative success factors, organizations can tailor recruitment, training, and incentives to maximize performance. Because independent sales representatives are not employees, understanding these factors is critical to firms engaging them. Translating established theory into testing with predictive analytics to identify meaningful success factors for rarely studied independent sales representatives has the potential to change the landscape for recr

The World Health Organization (WHO) reports that in 2018, 422 million people throughout the globe are living with diabetes, making it one of the most widespread chronic life-threatening conditions. Early diagnosis is often favoured for clinically relevant findings due to the comparatively longer asymptomatic period associated with diabetes. It is estimated that around 50% of people with diabetes go undiagnosed because of the length of time it takes for symptoms to appear. The appropriate evaluation of both common and less common sign symptoms, which may be present at various times between the onset of the illness and diagnosis, is essential for early detection of diabetes. Researchers have relied heavily on data mining-based categorization algorithms for illness risk prediction models. To estimate a person’s risk of developing diabetes, it is required to have access to data on people who have recently developed diabetes or who are at high risk of developing diabetes. A dataset of 768 instances was provided to us via Kaggle and was created by the National Institute of Diabetes and Digestive and Kidney Diseases. This set of examples was narrowed down from a bigger database using a variety of criteria. All our female patients are at least 21 years old and are indigenous Pima. We performed statistical analysis on the dataset using the Naïve–Bayes Algorithm, the Logistic Regression Algorithm, and the Random Forest Algorithm. We found that Random Forest provided the best accuracy for this dataset when evaluated using both ten-fold Cross- Validation and the percentage split method. The National Institute of Diabetes and Digestive and Kidney Diseases is the original source of this data. The goal is to diagnose a patient and then forecast whether they have diabetes based on those results. © 2022, The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd.

作者： Bisht, Tanvi Singh, Muskan Singhal, Shweta Indira Gandhi Delhi Technical University for Women Delhi India

Social media platforms such as Twitter serve as a powerful tool for real-time information dissemination and worldwide communication, shaping public opinions and providing a platform for diverse voices to be heard. The current study proposes methods to identify trending hashtags on Twitter over a six-month period (June to October 2021) and analyze the sentiment dynamics linked to these hashtags. In order to carry out trend analysis three classification algorithms—Naive Bayes, Gradient Boosting Decision Tree, and Random Forest—were evaluated. The results indicate that the Random Forest model outperformed the other two algorithms in accurately identifying trending hashtags. In addition to this, a comprehensive sentiment analysis was conducted using both rule-based and lexicon-based approaches. The VADER sentiment analysis was utilized as the foundation for the Support Vector Machine classifier which achieved an accuracy of 91.84%, while the TextBlob library provided additional sentiment insights. The majority of research results, leaned towards neutrality, indicating challenges in capturing sentiment complexities present in Twitter conversations. The findings highlight the effectiveness of machine learning approaches, while also recognizing the potential for deep learning techniques to enhance sentiment analysis in future research. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2024.

Behavioral Profiling of SCADA Network Traffic using Machine learning algorithms

作者： Jessica R. Werling Air Force Institute of Technology

学位级别：硕士

Mixed traffic networks containing both traditional information and communications technology (ICT) network traffic and supervisory control and data acquisition (SCADA) network traffic are more commonplace now due to the desire for remote control and monitoring of industrial processes. The ability to identify SCADA devices on a mixed traffic network with zero prior knowledge, such as port, protocol or IP address, is desirable since SCADA devices are communicating over corporate networks but typically use non-standard ports and proprietary protocols. Inspired by previous research success of machine learning (ML) in accurately classifying various protocols in Internet traffic, this research uses the following four supervised ML algorithms to identify SCADA network traffic within a mixed traffic trace: Na" ive Bayes, NBTree, J4.8, and BayesNet. Using packet timing, packet size and data throughput as traffic behavior categories, this research calculates 24 attributes from each device dataflow within a mixed traffic trace and introduces a novel approach of using these attributes to identify SCADA network traffic, achieving at least a.99 true positive rate (TPR). This research goes further by utilizing two attribute reduction functions to identify an optimal attribute subset, while maintaining the desired TPR of.99 for SCADA network traffic. The attributes and ML algorithms chosen for experimentation successfully demonstrate that a TPR of.9935 for SCADA network traffic is feasible on a given network. This research also successfully identifies an optimal attribute subset, while maintaining the.99 TPR. The optimal attribute subset identified in this research provides the SCADA network traffic behaviors that most effectively differentiating them from traditional ICT network traffic.

CREDIT CARD FRAUD DETECTION (Machine learning algorithms)

CREDIT CARD FRAUD DETECTION (Machine learning algorithms)

引用

作者： Fredrik Westerlund Umea University

学位级别：硕士

Credit card fraud is a field with perpetrators performing illegal actions that may affect other individuals or companies negatively. For instance, a criminal can steal credit card information from an account holder and then conduct fraudulent transactions. The activities are a potential contributory factor to how illegal organizations such as terrorists and drug traffickers support themselves financially. Within the machine learning area, there are several methods that possess the ability to detect credit card fraud transactions; supervised learning and unsupervised learning algorithms. This essay investigates the supervised approach, where two algorithms (Hellinger Distance Decision Tree (HDDT) and Random Forest) are evaluated on a real life dataset of 284,807 transactions. Under those circumstances, the main purpose is to develop a "well-functioning" model with a reasonable capacity to categorize transactions as fraudulent or legit. As the data is heavily unbalanced, reducing the false-positive rate is also an important part when conducting research in the chosen area. In conclusion, evaluated algorithms present a fairly similar outcome, where both models have the capability to distinguish the classes from each other. However, the Random Forest approach has a better performance than HDDT in all measures of interest.
