Topic: Advance in Swarm Intelligence Algorithms: Principle, Algorithms and Applications of Fireworks Algorithm

Date: Thursday, 19th May 2016

Time: 1 p.m.

Venue: WT712


Recently, inspired from the collective behaviors of many swarm-based creatures in nature or social phenomena, swarm intelligence (SI) has received attention and has been studied extensively, gradually becomes a class of efficiently intelligent optimization methods. Inspired by fireworks explosion at night, the fireworks algorithm (FWA) was developed in 2010. Since then, several improvements and some applications were proposed to improve the efficiency of FWA. In this talk, the fireworks algorithm is first described in detail and reviewed, then several effective improved fireworks algorithms are highlighted individually. By changing the ways of calculating numbers and amplitudes of sparks in fireworks’ explosion, the improved FWA algorithms become more reasonable and explainable. In addition, the multi-objective fireworks algorithm and the graphic processing unit (GPU) based FWA are also briefly presented, particularly the GPU-based FWA which is able to speed up the optimization process considerably. Extensive experiments on IEEE-CEC’s benchmark functions demonstrate that the improved fireworks algorithms significantly increase the accuracy of found solutions, yet decrease the running time dramatically. Finally, some applications of FWA are briefly described, while its shortcomings and future research directions are identified. 


KEDRI OPEN LECTURE - Prof. Massimiano Bucchi 

Speaker: Prof. Massimiano Bucchi, University of Trento, Italy

Topic : The Crisis of Mediators? Science Communication in the Digital age

Date: Monday, 22nd February 2016

Time: 1 p.m.

Venue : WT712


More than 25 years after the Royal Society report on Public Understanding of Science, there is hardly any doubt that science communication efforts aimed at non expert audiences have increased in quantity and intensity on a global scale. Public engagement and outreach activities have now become a routine – when not a prominent - feature for several research institutions in Europe. Budget and human resources are devoted to these activities, and researchers themselves are increasingly and even institutionally encouraged to pursue this ‘third mission’ alongside more traditional research and teaching duties. Does this ever more pressing public relations push, together with the increasingly central role of digital media and by research institutions, substantially undermine the role of traditional mediators of science communication (e.g. newspapers, magazines, TV/Radio shows and science museums and centres) as filters and warrants of the quality of information? What are the key challenges in this new context of ‘Science Communication’?

Massimiano Bucchi is Professor of Science and Technology in Society and of Science Communication at the University of Trento, Italy and has been visiting professor in several academic and research institutions in Asia, Europe and North America.

He has published several books (published in Italy, Brazil, Finland, China, Korea, UK and USA, Spain and Latin America), including Science in Society (London and New York, Routledge, 2004), Beyond Technocracy (New York, Springer, 2009) and Handbook of Public Communication of Science and Technology (ed. with B. Trench,  London & New York, Routledge, 2014) and papers in journals such as Nature and Science. In 2016 he will become editor of the international peer reviewed journal Public Understanding of Science (Sage).

7 February 2012 - KEDRI Open Lecture on "Intelligent Systems: An Assessment of the Past and the Prospects for the Future" by Prof. Okyay Kaynak

The KEDRI Open Lecture is being sponsored by School of Engineering and School of Computing and Mathematical Sciences.

The last decade of the last millennium is characterized by what might be called the intelligent systems revolution, as a result of which, it is now possible to have man-made systems that exhibit ability to reason, learn from experience and make rational decisions without human intervention.  Prof. Zadeh has coined the word MIQ (machine intelligence quotient) to describe a measure of intelligence of man-made systems.  In this perspective, an intelligent system can be defined as a system that has a high MIQ.

In the presentation the state-of-art reached in intelligent systems is overviewed with examples and a perspective on the future is given.  The reasons behind the slow pace of developments are discussed.  The talk closes with a consideration of the possible research directions in mechatronics and robotics as driving forces behind the development of intelligent systems.

3 March 2011 - KEDRI Seminar by Dr. Gisela Klette on "A Recursive Algorithm for the Computation of the Relative Convex Hull"

The relative convex hull of a simple polygon A, contained in a second simple polygon B, is known to be the minimum perimeter polygon (MPP).

Digital geometry studies a special case: A is the inner and B the outer polygon of a component in an image, and the MPP is called minimum length polygon (MLP). The MPP or MLP, or the relative convex hull, are uniquely defined. The paper recalls properties and algorithms related to the relative convex hull, and proposes a (recursive) algorithm for calculating the relative convex hull. The input may be simple polygons A and B in general, or inner and outer polygonal shapes in 2D digital imaging. The new algorithm is easy to understand, and is explained here for the general case. The worst case time complexity is quadratic, but it runs for "typical'' (as in image analysis) inputs in linear time.

Dr. Gisela Klette has a Master’s degree in Mathematics from the Friedrich-Schiller-University (Jena, Germany) and a PhD in medical image analysis from the University at Groningen (The Netherlands). She was working in a combined teaching and research position at the University of Auckland between 2002 and 2007. She is now a part-time lecturer at AUT.
Her research interests are in medical image analysis, in particular in applications of discrete geometry. She is a reviewer for journals such as IEEE Transactions in Pattern Analysis and Machine Intelligence, Theoretical Computer Science and Acta Cybernetica.

6 August 2009 – KEDRI Seminar on Kinetics models and laser photolysis

Title: Analysis of synaptic transmission and its regulation by channel
Speaker: Prof. Hiroshi Kojima, Laboratory for Cellular and Molecular Physiology, Tamagawa University, Tokyo Japan

The presentation will introduce the physiological experiments and techniques which enable us to understand the background of the synaptic transmission. Then it will explain how the rate constants of AMPA receptor channel kinetics model of neural cells which could induce the change in efficacy of synaptic transmission can be predicted with computer simulation.

Excitatory postsynaptic currents (EPSCs) were reconstructed by computer calculation. Moreover, electrical responses were measured from neurons by using laser uncaging experiments. It was shown that the properties of the evoked current responses by photolysis and those obtained spontaneous synaptic currents have the similar properties. It is also suggested that the present method based on kinetics models and uncaging method could be used for the investigation of the integration and regulation by neural cells.

11th December 2008 - KEDRI seminar on "Progress and challenges in vision-based driver assistant systems"

Speaker: Professor Reinhard Klette, Computer Science Department, University of Auckland

The talk will discuss computer vision challenges in the context of vision-based driver assistant systems, certainly one of the most difficult areas of current 3D image analysis due to (1) the expectation of being "legally soundproof" at night or in the rain, at 120km/h, in Queen Street at rush hour, and so forth, also due to (2) the real time request, and (3) expectations to look about 3 seconds ahead - what may happen next in front of the car, at the location where the ego-vehicle is expected to be? Actually, car companies have started in 1995 to add vision solutions into their top-end models. What can we add to this in New Zealand, without having any car production line in the country? The talk will suggest collaboration between KEDRI/AUT an the .enpeda.. team.

9th August 2007 - KEDRI Seminar

Prof Ajit NarayananSpeaker: Professor Ajit Narayanan,Head of School of Computing and Mathematical Sciences, AUT
Topic: Intelligent Bioinformatics and Cancer Systems Biology: The Computational Search for Killer Genes

The presentation will deal with a systems level view of cancer. Science goes through three interacting phases: measurement/observation, understanding, and control. Systems biology is the application of computational, mathematical and engineering concepts and techniques for understanding and, ultimately, controlling biological processes. The focus of the talk is on the following questions: (a) What are the basic structures and properties of a cancer biological network? (b) How does a cancer biological system behave over time under various conditions? (c) How does a cancer biological system maintain its robustness and stability? (d) How can we modify or construct cancer biological systems to achieve desired properties? The talk will start with an introduction to the 'standard' model of cancer before examining recent research from a cancer systems biology perspective that questions some aspects of the standard model, leading to new hypotheses of what causes cancer.
No previous knowledge of cancer or biology is assumed.

24th of August 2006 - KEDRI Seminar by Dr. Petr Pancoska

Topic: Genes, Graphs and Proteins – Lessons for Novel Methods of Data Analysis


Dr. Petr Pancoska studied Chemistry at the Faculty of Sciences of the Charles University Prague while working simultaneously on research projects at the Institute of Organic Chemistry and Biochemistry of the Czechoslovak Academy of Sciences at Prague. He did his PhD. in experimental physics at the Faculty of Mathematics and Physics of the Charles University Prague. After postdoctoral work at the Bochum University (Germany) he was faculty at the Department of Chemical Physics of the Charles University Prague. He is also founding and board member of the International Centre for Discrete Mathematics, Theoretical Computer Science and Applications (DIMATIA) at the Charles University. From 1994-2003 he was faculty at the Department of Chemistry of the University of Illinois at Chicago. Currently he is faculty at the Stony Brook University. Research interests cover applications of advanced data analysis methods, novel applications of mathematics in bioinformatics, cancer research, bio-nanotechnology, molecular biology, virology, drug design and disease diagnostics, optical spectroscopy of biomolecules, experimental and theoretical studies of primary processes of photosynthesis.

The evolutionary history of nucleotide and protein sequences is usually inferred from multiple sequence alignments. We show in the first part of the presentation that – using an innovative graph-theoretical approach – it is possible to extract evolutionary constraints within single sequences. This novel approach has firm physico-chemical basis: The multiplicity of realizations of the “wild type” thermodynamic state of any gene position is calculated via representation of gene sequence via Eulerian graph. This innovative descriptor reveals previously unseen dimension of information content within genomes. The multiplicity technique is entirely model-free, there is no need to do multiple sequence alignments or parameterize evolutionary rates or distributions. A direct observation of the sequence via thermodynamic “tolerance” reveals where evolution has happened and how important mutations in each particular position are in comparison to other positions (even if they have the same local sequence). No other technique (alignment entropy, codon bias, Ka/Ks ratio) has a similar potential. We show practical applications of this novel analysis in drug design, prediction of emergence of mutations of influenza viruses that induce drug resistance, in quantitative prognostics of treatment of HIV patients and for identification of “barcode” segments of pathogens for microarray-based bio-defense applications.

In the second part we will use the insight gained from the above biological applications for more general analysis of large graphs and networks. First we will exploit the unique topological structure of any Eulerian graph E. We show that a (weighted) graph g can be converted into an (oriented) multigraph G. Then : i) Each E-subgraph of G can be decomposed into a (small)“basis”of independent cycles and encoded digitally in a vector; ii) E-subgraph of a network is deterministically associated with a linear sequence of events. Moreover, the multiplicity of this sequence of events provide a measure of its uniqueness; iii) Topology of any E-subgraph defines the “command structure” of interacting blocks, which govern the events sequence. iv) The results of i)-iii) can be used for direct design of networks with pre-defined properties and interactions between its components.

Next we will exploit the broader consequences of the fact that all biological “information media” are chiral. We will show some results of the theoretical analyses of this natural phenomenon for chiral subgraphs C of g. i) Ruch’s theory associates the topology of C (via characters of its symmetry and permutation groups) with a unique chirality function that describes the mode of interactions between the C components. ii) The existence of parity-odd and parity even observables can represent two different responses of a network to a stimulus. We will demonstrate on a simple conceptual example, that the magnitude of the differential response depends on a level of interaction between the components of C.

3rd of August 2006 - KEDRI Seminar by Prof. Mario Fedrizzi

Topic: Modelling Consensual Dynamics in Group Decision Making in the Framework of Fuzzy Preferences

Prof. Mario Fedrizzi is a Professor and Chair of Mathematics for Decisions, Faculty of Ecomomics, and the Deputy Rector, University of Trento, Italy. His current research focuses on: utility and risk theory; stochastic dominance; group decision analysis; decision support systems; fuzzy decision analysis; fuzzy mathematical programming; fuzzy regression analysis; consensus modeling in uncertain environments. Prof. Fedrizzi is also involved in consulting activities for information systems and DSS design and implementation; office automation; process quality control; project management; expert systems and neural nets in financial planning; ERP systems design and implementation.

One of the central issues to address when we are faced with the preference aggregation task in social choice theory is that of modelling consensus. The notion of consensus plays an important role whenever the social choice scheme is based on a strategy of gradually combining the various individual preferences into some form of collective preference structure.

In the development of fuzzy approaches to group decision making the notion of consensus has evolved from a binary index of unanimous agreement to a graded (soft) measure of collective agreement among the individual decision makers whose preferences are represented by fuzzy binary relations.

Here we propose some extensions of the fuzzy approaches to consensus reaching processes combining a soft measure of collective dissensus with an inertial mechanism of opinion changing aversion. The collective consensual trend corresponds to a process of anisotropic diffusion among the individual preferences structure. The anisotropy is designed so as to outline and enhance the natural group segmentation into homogeneous subgroups. The individual inertial mechanism, on the other hand, opposes changes from the original preferences and provides an appropriate framework to deal with preference outliers.

1st of August 2006 - KEDRI Open Lecture Series XProf Mario Fedrizzi

Topic: Theories of Decision Making Under Risk and Uncertainty: A Selected Survey of Mathematically-based Approaches in the Second Half of the 20th Century

Prof. Mario Fedrizzi is a Professor and Chair of Mathematics for Decisions, Faculty of Ecomomics, and the Deputy Rector, University of Trento, Italy. His current research focuses on: utility and risk theory; stochastic dominance; group decision analysis; decision support systems; fuzzy decision analysis; fuzzy mathematical programming; fuzzy regression analysis; consensus modeling in uncertain environments. Prof. Fedrizzi is also involved in consulting activities for information systems and DSS design and implementation; office automation; process quality control; project management; expert systems and neural nets in financial planning; ERP systems design and implementation.

The monumental treatise on rational choice and the theory of games of John von Neumann and Oskar Morgenstern, published in 1947, have profoundly influenced mathematical research in decision making modelling through the rest of the 20th century. K. Arrow’s approach on social choice theory, L. Savage’s axiomatic foundations for subjective utility theory, G. Debreu’s theory of value and R. Keeney and H. Raiffa’s work on preferences and value tradeoffs have been directly derived from the seminal work of von Neumann and Morgenstern. The decision making framework introduced by the two authors, usually referred to as the expected utility model, have come under increasing fire due the weakness of its explanatory power for real world decision processes. P. Fishburn, D. Kahneman and A Tversky, M. Machina, D. Schmeidler and others introduced generalizations accommodating reasonable behaviours of decision makers that were considered inconsistent with the axiomatic framework of the original expected utility model. 

The main scope of the lecture is to provide an historical overview of the basic normative decision making models based on the representation of preference structures. Strengths and weaknesses of the different approaches will be enlightened in the perspective of the impact of the models on the ways in which decisions are made. Some basic problems related to the representation and management of risk, vagueness and imprecision will be addressed.

Field of Specialisation: Computational Neuroscience and Modeling of Neural Networks, Intelligent Informatics

Research topics
A spatio-temporal learning rule and information representation in memory networks; Self-organisation of information representation; A dynamic aspect of neural coding.

Research activities
To experimentally investigate self-organization of information representation in the neural memory system, and to design a theoretical model of the hippocampal-cortical memory system of storing and retrieving information.

The following kinds of information representation are identified in experiment and model study: Dynamic cell assembly; Information integration by temporal correlation among events; A spatio-temporal learning rule; A dynamic non-linear process of storing and retrieving information

The Hebbian synaptic learning rule requires coactivity of presynaptic and postsynaptic neurons. However, under some conditions, information regarding the postsynaptic action potentials, carried by backpropagating action potentials, can be strongly degraded before it reaches the distal dendritic synapse of the hippocampal CA1 (Spruston, et al.,1995; Andreasen and Ross,1995; Callaway and Ross,1995; Stuart, et al.,1997; Golding et al., 2001). Yet, recent results (Golding et al., 2002) have shown that LTP can indeed occur at synapses on distal dendrites of hippocampal CA1 pyramidal neurons, even in the absence of a postsynaptic somatic spike.

Based on results observed in hippocampal LTP, induced by various spatiotemporal pattern stimuli (Tsukada et al.,1990,1994), the spatiotemporal learning rule (STLR) was proposed by Tsukada et al. (1996,1998). The novel point of this learning rule was “Cooperative plasticity without a postsynaptic spike”, which we tested physiologically in the CA1 hippocampal network (Yamazaki et al.,2006), and its temporal summation.

The learning rule incorporated two dynamic process: fast (10 to 30ms) and slow (150 to 250ms). The fast process works as a time window to detect a spatial coincidence among various inputs projected to a weight space of the hippocampal CA1 dendrites, while the slow process works as a temporal integrator of a sequence of events.

In a previous paper (T.Aihara et al.,2000) the decay constant of fast dynamics was identified as 17ms by parameter fitting to the physiological data of LTP, Cell assemblies were synchronized at this time scale, while matches the period of the hippocampal gamma oscillation, and that of the slow is 169ms, which corresponds to a theta rhythm. We (Tsukada and Pan, 2005) systematically examine the functional difference between STLR and Hebbian learning rules in a single–layered neural network, computing their ability to differentiate spatiotemporal sequence. In this paper, we tested physiologically the cooperative plasticity without a postsynaptic spike in the CA1 hippocampal network.

Automatic fuzzy rule based model identification started with Sugeno and Yasukawa's paper in 1992. The first approaches were based on clustering, especially fuzzy c-means clustering. Later several essential improvements have been added and alternative learning techniques were applied (with T. Gedeon and A. Chong). Bacterial algorithms introduced by Furuhashi could be used for slow but global model optimisation (with J. Botzheim and B. Hamori), while the Levenberg-Marquardt algorithm successfully used for neural network optimisation could be extended to more complex fuzzy models as a fast but locally converging technique (with A. Ruano, C. Cabrita and J. Botzheim). Our most recent results combine the advantages of these two, in the form of a Bacterial Memetic Algorithm, where fast and global optimum could be reached. Some benchmark problems will illustrate the power of the new approach.
