Differential Evolution for Evolutionary Computation Challenges: examples from tree growth, energy scheduling, and deep ocean underwater robotics

Dr. Aleš Zamuda, Ph.D.
Institute of Computer Science | Computer Architecture Lab.
University of Maribor

Differential Evolution (DE) as a flagship algorithm for evolutionary computation, is applicable to vast amount of challenges. Three example approaches using DE with different requirements will be presented, emphasizing the perspective of large scale optimization, time constraints, and big data assisted optimization model tailoring. In this perspective, the three examples are given from computer vision, energy, and robotics. For computer vision, spatial procedural tree growth and sway animation reconstruction from processing multiple view images with DE will be presented. In energy domain, a top performing system for hydrothermal scheduling using DE will be highlighted, which uses a tailored model that is assisted with big data approaches for surrogate optimization. In robotics and navigation, underwater glider path planning challenges will be presented, where evolutionary computation has been used for first time and significantly improves vessel capabilities by improving navigation robustness and optimizing trajectories.

Genetic Improvement

Dr. Bobby R. Bruce, Ph.D.
Software Systems Engineering Group
University College London
United Kingdom

Genetic improvement is an emerging area of software engineering where code is automatically modified by search-based processes. In the last few years, researchers in this field have produced tools and frameworks shown to be human competitive and suitable for solving real-world software engineering problems. This talk shall give an introduction to genetic improvement, discuss the state-of-the-art, and explain how genetic improvement tools are built. Bobby will conclude the talk with a short tutorial on optimising a piece of software’s execution time using the ‘Genetic Improvement in No time’ framework (GIN — available at ).

Bobby R. Bruce is a software engineering researcher specialising in the emerging area of genetic improvement -- the use of search, particularly evolutionary search, to improve software with respect to some user-defined objective. His PhD thesis, ‘The Blind Software Engineer’ focused on the the use of such techniques to improve software’s non-functional properties. Having completed his PhD in software engineering at UCL's Centre for Research on Evolutionary Search and Testing (CREST), Bobby is starting a position as a post-doctorial scholar at the University of California, Los Angeles, focusing on the dynamic optimisation of Java bytecode. He remains interested in genetic improvement, particularly in how it may be used to aid in the parallelisation of software; a task which human developers typically find difficult.

Principles and Applications of Cellular Automata

Dr. Michal Bidlo, Ph.D.
Department of Computer Systems
Brno University of Technology
Czech Republic

In this talk the basic principles and applications of cellular automata (CA) will be introduced and some recent results regarding evolutionary design of complex CA will be presented. In particular, the talk will be devoted to multi-state uniform cellular automata. As the recent research has shown, the representation of transition functions of CA for evolutionary algorithms may significantly improve the results that can be obtained for various case studies. Specifically, the generic square calculation problem in 1D CA and pattern development problem in 2D CA will be considered. It will be demonstrated that various square calculations in cellular automata can be discovered, some of which substantially overcome the known solution. Moreover, several results of the pattern development will be shown which have not been achieved before using conventional design methods. Some of the results indicate that an exact CA behaviour can be automatically designed by evolution even for cellular automata working with more than 10 cell states.

Dr. Michal Bidlo is an assistant professor at Brno University of Technology (BUT), Faculty of Information technology (FIT), Czech Republic. Since the beginning of his career dr. Bidlo has participated in the research of Evolvable Hardware group at BUT FIT with the main research interests including natural computation, cellular automata, evolutionary deisgn, evolvable hardware and bio-inspired systems. He is the author or co-author of over 20 conference/journal papers in these areas. He has published at renowned international conferences and in international journals (e.g. IEEE Transactions on Evolutionary Computation or Soft Computing) and has served as an active PC member of several international conferences (e.g. DATE, GECCO, CEC, ICES). In addition to his research, dr. Bidlo teaches several courses at BUT FIT, including Applied Evolutionary Algorithms, Bio-Inspired Computers or Design of Computer Systems. For his research work he was awarded by Silver medal at the international competition HUMIES - Awards for Human-Competitive Results Produced by Genetic and Evolutionary Computation in 2016 for his method for the evolutionary design of complex cellular automata, and received the Best Paper Award at 2016 International Joint Conference on Computational Intelligence - Evolutionary Computation Theory and Applications.

A Small World Hidden in Evolutionary and Swarm Based Algorithms

assoc. Prof. Roman Senkerik, Ph.D.
Department of Informatics and Artificial Intelligence
Tomas Bata University in Zlin
Czech Republic

This tutorial represents an insight into an attractive open research task, which is a novel method for visualizing the dynamics of evolutionary and swarm-based algorithms in the form of networks. The idea is based on the similarity in interactions between individuals in the metaheuristics algorithms and for example, users of social networks, linking between web pages, etc. The population is visualized as an evolving complex network that exhibits non-trivial features. The features like clustering, centralities, communities, and many more, offer a clear description of the population under evaluation. This tutorial shows the differences between the types of complex networks used, variations in building complex networks to capture the population dynamics of evolutionary algorithms or communication inside swarm-based algorithms, investigation on the time development of the network. It also shows several successful utilization of complex networks attributes for the performance improvements through the adaptive population as well as parameter/strategy control, further the possibility of controlling the evolution through complex network features.

Roman Senkerik was born in the Czech Republic, and went to the Tomas Bata University in Zlin, Faculty of applied informatics, where he studied Technical Cybernetics and obtained his MSc degree in 2004, Ph.D. degree in 2008 (Technical Cybernetics) and Assoc. prof. degree in 2013 (VSB – Technical University of Ostrava – degree in Informatics). He is now a researcher and lecturer at the same university. He was IPC member or session chair of many important international conferences IEEE CEC, IEEE SSCI, ECMS, MENDEL, HAIS etc. He is Recognized Reviewer for many Elsevier journals as well as many other leading journals in computer science/computational intelligence. He was a part of the organizing teams for Special Sessions/symposiums at IEEE CEC and IEEE SSCI events. He was a guest editor of several Special Issues in journals, editor of Springer proceedings for several conferences.

 Commercial Tutorial
Deep Learning not only for Computer Vision using MATLAB

Jaroslav Jirkovsky, Ph.D.
Senior Application Engineer
International Reseller of MathWorks, Inc., U.S.A.
Czech Republic

Convolutional neural networks are essential tools for deep learning, and are especially useful for image classification, object detection, and recognition tasks. CNNs are implemented as a series of interconnected layers. In MATLAB, you can construct a CNN architecture, train a network, and use the trained network to predict class labels or detect objects using R-CNN, Fast R-CNN and Faster R-CNN object detectors. You can also extract features from a pretrained network, and use these features to train a classifier, or train convolutional neural networks for regression tasks. What the network learns during training is sometimes unclear. Deep Dream is a feature visualization technique in deep learning that synthesizes images that strongly activate network layers. By visualizing these images, you can highlight the image features learned by a network.
