In the context of addressing the problem of people who do not undergo a diagnosis of heart failure due to pulmonary conditions on time, a solution to this problem would allow early preventive detection to avoid the development of severe disease efficiently. Our approach employs the use of medical data retrieved from the user to determine and predict whether there is a likelihood of a potential condition. To solve this problem, according to a users medical measurement history, a deep learning model can be implemented to determine a preventive diagnosis or otherwise to follow up on an already detected condition. By posing the problem as a classification task, it can be taken advantage of a deep learning model focused on heart failure or pulmonary conditions to make a preliminary diagnosis and determine if there are signs of any symptomatology.

As people keep a watch eye on the oral health, more people choose to go to professional dental hospitals for the regular dental examinations and diagnosis. It is well known that the dental diagnosis and treatment require excellent nursing skills and extensive experience by the dentists. Nervously, the number of experts is limited. However, the rapid increase in the number of diagnoses and the small number of professional dentists resulted in an increase in the daily diagnostic frequency of dentists, and the overworked working hours seriously affected the energy and diagnostic efficiency of dentists. This study for the sake of reduce the burden of dental diagnosis, proposes a computer-aided diagnosis method. This method classifies gingivitis images by using the image feature extraction method of fractional Fourier entropy (FRFE) and biogeography-based optimization (BBO) algorithm. The FRFE coefficient extracted from the image was used as the input feature vector, and the classification was carried out by the BBO algorithm with the optimal scheme of automatic screening. After 10-fold cross-validation, more effective healthy and pathological gingival image classification results were obtained compared with the latest methods.

Cybercriminals have increasingly used spam email to send scams, phishing, malware and other frauds to organisations and people. They design sophisticated and contextualised emails to make them look trustworthy for users, being the sender addresses an essential part. Although cybersecurity agencies and companies develop products and organise courses for people to detect emails patterns, spam attacks are not totally avoided yet. This work presents a proof-of-concept methodology to give the user more meaningful information about trustworthiness to detect these harmful emails. For the first time in the literature, we present an email address dataset manually labelled into two classes, low and high quality. Moreover, we extracted 18 handcrafted features based on social engineering techniques and natural language properties. We evaluated four popular machine learning classifiers and obtained the best performance with Naive Bayes, i.e., 88.17% of accuracy and 0.808 of F1-Score. Additionally, we applied the InterpretML framework to find out the most relevant properties to eventually implement an automatic system able to inform about the trustworthiness of email addresses.

Traditional statistical process control is used in many industries to monitor process variables and is usually based on univariate data analysis. If one of the variables falls out of the acceptable limits, the process is out of control. However, many chemical processes are multivariate continuous processes with many highly correlated variables;therefore a univariate data analysis is not very effective for these types of processes. Statistical multivariable process control overcomes some of the limitations of singlevariable monitoring by simultaneously analyzing all the variables using principal component analysis (PCA). An unsupervised neural network using Hebbian learning rules is proposed. The proposed neural tools, Hotelling's (T-2) and Predicted Square Error (Q), are used to monitor the process. These statistical tools are applied to the outputs of the PCA model and are used to define a reference system based on the interpretation of logged data obtained from the process.

Abstract-To facilitate more efficient and convenient online office work, major enterprises have launched mobile portal applications, integrating various office micro-applications to provide employees with a unified entry point. However, employees in different positions have varying application demands and there is a lack of a personalized recommendation mechanism. Accurately profiling employees has thus become a research focus for many scholars. In response to this issue, this paper proposes a multi-layered employee profile system for power enterprises. We designed a data collection model suitable for processing massive logs, and used LSTM and mini-batch K-means algorithms to cluster employees at two levels: application usage and provincial distribution. Employee labels were established through statistical characteristics and professional analysis, and a classification model was trained for employee profiling. To verify the effectiveness of the system proposed in this paper, real data was collected to conduct experiments. The results were compared with traditional clustering algorithms and other outstanding profile algorithms from previous studies. The findings demonstrate that the profile system proposed in this paper achieves superior performance in profiling employees of power enterprises compared to other algorithms. © 2023 IEEE.

A framework about spectral based vegetation classification was proposed, which serves as a core methodology of the vegetation spectral knowledge base. The hyperspectral reflectances of 13 types of plants were measured by an ASD FieldSpec 4 spectroradiometer. Two forms of spectral features were used for representing the key spectral characteristics of plants,including Vegetation index(VI) and spectral shape features. Based on these spectral features, a sensitivity analysis was performed to identify the most important features for establishing the classifier. The analysis of variance(ANOVA) and the cross-correlation analysis were applied to derive the sensitivity of features and remove features that have high correlations. Then, a classification method for differentiating plants was established by coupling some spectral similarity measures(e.g., ED) with some classification methods(e.g.,BPANN and SVM). The results of discrimination analysis showed that a highest accuracy was produced by SVM with the OAA over 99% when using 7 sensitive VIs. The results suggested the framework about spectral based vegetation classification can form a basis for spectral knowledge base and application technology and further achieve a wide range of plant classification based on remote sensing.

With the completion of the human genome sequencing, a large number of data especially amino acid sequences floods into biological database, How to analyze these data quickly and even predict the structure and function of protein correctly have become hot topics in recent years, In this paper, we mainly study K-means clustering algorithm and KNN classifier in amino acid sequences of complicated data, which are applied in the prediction of protein sub-cellular localization. In many cases, fuzzy boundary and unbalance are frequently appeared among biological data. The accuracy will be lower, if we make a prediction through traditional KNN and K-means clustering algorithm directly. Firstly, in order to make clear the unbalance, we propose the within-class thought to make sure that training samples in each class around the testing sample are selected and we introduce membership to tell which class the testing sample belongs to. Then, we bring in rough sets and membership to solve the fuzzy boundary. Particularly, we apply correlation coefficient in the rough sets to better reflect the relationship among data objects. The experimental results based on protein sub-cellular localization prediction show that the methods proposed newly better work than the traditional methods.

k-Nearest Neighbor (k-NN) classification technique is one of the most elementary and straightforward classification methods. Although distance learning is in the core of k-NN classification, similarity can be preferred upon distance in several practical applications. This paper proposes a novel algorithm for learning a class of an instance based on a similarity measure which does not calculate distance, for k-Nearest Neighbor (k-NN) classification.

Online Social Networks (OSNs) are deemed to be the most sought-after societal tool used by the masses world over to communicate and transmit information. Our dependence on these platforms for seeking opinions, news, updates, etc. is increasing. While it is true that OSNs have become a new medium for dissemination of information, at the same time, they are also fast becoming a playground for the spread of misinformation, propaganda, fake news, rumors, unsolicited messages, etc. Consequently, we can say that an OSN platform comprises of two kinds of users namely, Spammers and Non-Spammers. Spammers, out of malicious intent, post either unwanted (or irrelevant) information or spread misinformation on OSN platforms. As part of our work, we propose mechanisms to detect such users (Spammers) in Twitter social network (a popular OSN). Our work is based on a number of features at tweet-level and user-level like Followers/Followees, URLs, Spam Words, Replies and HashTags. In our work, we have applied three learning algorithms namely Naive Bayes, Clustering and Decision trees. Furthermore, to improve detection of Spammers, a novel integrated approach is proposed which "combines" the advantages of the three learning algorithms mentioned above. Improvement of spam detection is measured on the basis of Total Accuracy, Spammers Detection Accuracy and Non-Spammers Detection Accuracy. Results, thus obtained, show that our novel integrated approach that combines all algorithms outperforms other classical approaches in terms of overall accuracy and detect Non-Spammers with 99% accuracy with an overall accuracy of 87.9%.
