This book explores the critical issue of fairness in human-machine interfaces. It delves into the integration of technology and cognitive science to develop AI systems that are unbiased, reliable, and user-friendly. The book also sheds light on emotional data processing in AI accelerators and federated learning modules. Additionally, it covers machine learning, knowledge representation, and the application of knowledge graphs to understand and optimize the behaviour of AI assistance devices. - Explains complex issues of Cognitive Fairness Aware Contextual Proactive Federated Protocol collects data and identifies individual emotional issues and resolves them by contextual solitary proactive communication - Discusses emotional data processing challenges through AI accelerator with federated learning module to generate periodical counselling messages - Data analysis anomalies are addressed in Graph Data Base Modelling by anomaly prediction and anomaly detection - Describes anomaly detection techniques in the form of abnormal data records, messages, events, groups, and/or other unexpected observations in graph database modelling - Outlier detection for data analysis deals with the detection of patterns in Graph Data Base This book is for researchers, academics, students, AI Practitioners and Developers, Ethics Experts in AI Technology and machine-learning practitioners interested in fairness in human-machine interfaces.
