Automatic Clustering of User Behaviour Profiles for Web Recommendation System

Abstract

Web usage mining, content mining, and structure mining comprise the web mining process. Web-Page Recommendation (WPR) development by incorporating Data Mining Techniques (DMT) did not include end-users with improved performance in the obtained filtering results. The cluster user profilebased clustering process is delayed when it has a low precision rate. Markov Chain Monte Carlo-Dynamic Clustering (MC 2 -DC) is based on the User Behavior Profile (UBP) model group's similar user behavior on a dynamic update of UBP. The Reversible-Jump Concept (RJC) reviews the history with updated UBP and moves to appropriate clusters. Hamilton's Filtering Framework (HFF) is designed to filter user data based on personalised information on automatically updated UBP through the Search Engine (SE). The Hamilton Filtered Regime Switching User Query Probability (HFRSUQP) works forward the updated UBP for easy and accurate filtering of users' interests and improves WPR. A Probabilistic User Result Feature Ranking based on Gaussian Distribution (PURFR-GD) has been developed to user rank results in a web mining process. PURFR-GD decreases the delay time in the end-to-end workflow for SE personalization in various methods by using the Gaussian Distribution Function (GDF). The theoretical analysis and experiment results of the proposed MC 2 -DC method automatically increase the updated UBP accuracy by 18.78%. HFRSUQP enabled extensive Maximize Log-Likelihood (ML-L) increases to 15.28% of User Personalized Information Search Retrieval Rate (UPISRT). For feature ranking, the PURFR-GD model defines higher Classification Accuracy (CA) and Precision Ratio (PR) while utilising minimum Execution Time (ET). Furthermore, UPISRT's ranking performance has improved by 20%.

Epilepsy Identification using Hybrid CoPrO-DCNN Classifier

“…There is a substantial increase in band power for epileptic conditions across all detectors, reinforcing the notion of altered frequency characteristics [93] during seizures. Entropy measures the disorder or unpredictability in [94] the signals. There is a notable increase in negative entropy values for epileptic conditions, indicating a higher degree of disorder [95] and complexity during seizures.…”

“…A decrease in alpha/delta ratio suggests reduced alpha activity relative to slow-wave delta activity, [116] which may be indicative of abnormal cortical functioning observed in epilepsy. An increase in theta/delta variance suggests [117] greater variability in the balance between theta and delta activity, which could reflect dynamic changes in brain states associated with epileptic activity. A high positive skewness in theta/alpha ratio indicates an asymmetric distribution [118], [119] with a longer tail towards higher values, suggesting dominance of theta activity over alpha activity.…”
