In this paper, a hybrid approach for clustering categorical data is developed. It integrates the ROCK clustering algorithm with genetic algorithm for the betterment of accuracy. The developed approach is tested for four datasets obtained from the University of Irvine (UCI) machine learning repository. Accuracy is used as the measure of performance for accessing the quality of the clusters. The performance of the integrated approach is compared with the performance of ROCK (robust clustering using links) clustering algorithm. The result shows that the integrated approach yields higher accuracies than the ROCK clustering approach.
In recent years, the increase in internet usage also led to an increase in data. Therefore, the importance of classification has increased to understand and analyze the data more easily, and this made emotion analysis...

Face authentication is an important biometric authentication method commonly used in security *** is vulnerable to different types of attacks that use authorized users’facial images and videos captured from social media to perform spoofing attacks and dynamic movements for penetrating secur-ity *** paper presents an innovative challenge-response emotions authentication model based on the horizontal ensemble *** proposed model provides high accurate face authentication process by challenging the authorized user using a random sequence of emotions to provide a specific response for every authentication trial with a different sequence of *** proposed model is applied to the KDEF dataset using 10-fold *** improvements are made to the proposed ***,the VGG16 model is applied to the seven common ***,the system usability is enhanced by analyzing and selecting only the four common and easy-to-use ***,the horizontal ensemble technique is applied to enhance the emotion recognition accuracy and minimize the error during authen-tication ***,the Horizontal Ensemble Best N-Losses(HEBNL)is applied using challenge-response emotion to improve the authentication effi-ciency and minimize the computational *** successive improvements implemented on the proposed model led to an improvement in the accuracy from 92.1%to 99.27%.
This paper defines a formal model that organizes agents into a social hierarchal structure so that they can easily communicate and negotiate. It also delineates the main algorithms agents can employ in order to achiev...
