This book constitutes the refereed proceedings of the16th International Conference on Intelligent Data Engineering and AutomatedLearning, IDEAL 2015, held in Wroclaw, Poland, in October 2015.

The 64 revised full papers presented were carefullyreviewed and selected from 127 submissions. These papers provided a valuablecollection of recent research outcomes in data engineering and automatedlearning, from methodologies, frameworks, and techniques to applications. Inaddition to various topics such as evolutionary algorithms, neural networks,probabilistic modeling, swarm intelligent, multi-objective optimization, andpractical applications in regression, classification, clustering, biologicaldata processing, text processing, video analysis, IDEAL 2015 also featured anumber of special sessions on several emerging topics such as computationalintelligence for optimization of communication networks, discovering knowledgefrom data, simulation-driven DES-like modeling and performance evaluation, andintelligent applications in real-world problems.
