Plenary Lectures

Plenary Lecture in Symposium: New Development of Simulational Science in Statistical Physics Recent Development of Markov-Chain Monte Carlo in Computational Physics Synge Todo, Professor Department of Physics, University of Tokyo Institute for Solid State Physics, University of Tokyo Mathematics and Informatics Center, University of Tokyo CMI2, MaDIS, National Institute for Materials Science

Abstract: Recent development of the Markov-chain Monte Carlo (MCMC) method is discussed. Although the MCMC is a versatile and powerful tool in many applications, it often suffers from slow convergence and reduction in the number of effective samples. This problem can be solved by introducing several novel techniques such as the non-local global update, worm algorithm, irreversible kernel, event-driven technique, geometric allocation scheme, and so on.

Biography: Synge Todo received his Ph.D. from University of Tokyo in 1996. After PostDoc and Research Associate at Institute of Solid State Physics, University of Tokyo, PostDoc at Theoretical Physics, ETH Zurich, Lecturer at Department of Applied Physics, University of Tokyo, and Project Professor at Institute of Solid State Physics, University of Tokyo, he became Associate Professor at Department Physics, University of Tokyo in 2014.

Plenary Lecture in Symposium: Numerical Simulation and Visual Analytics of Nonlinear Problems Visual Causality Exploration and its applications Koji Koyamada, Professor Academic Center for Computing and Media Studies, Kyoto University, Japan

Abstract: In the big data era, it is expected that every citizen can access the open data and participate in a scientific research. For realizing such a data science, visualization techniques will play an important role since they will enable the big data to be transmitted to the brain efficiently. It is highly expected for visualization to facilitate an exploration of a causality in a data science field. Although it is possible to calculate a correlation between data items (variables) by using a statistic method, the causality is a feature which domain experts can clarify by making the best of their professional knowledge. There are several examples of illogically inferring causation from correlation. That is why a visualization plays an important role in the scientific discovery. In this talk, we would like to introduce our activities on visual causality exploration. They include an interactive specification of a latent variable which explains several observable variables by using a causality graph in a phenotypic expression network, and an interactive exploration of a causality between two time-varying variables defined on computational grids.

Biography: Prof. Koji Koyamada is currently a professor at the Academic Center for Computing and Media Studies, Kyoto University, Japan. His research interest includes modeling & simulation and visualization. He is an associate member of the Science Council of Japan, a former president of the Visualization Society Japan, and a former president of Japan Society of Simulation Technology.

He received his B.S., M.S. and Ph.D. degrees in electronic engineering from Kyoto University, Japan in 1983, 1985 and 1994, respectively, and worked for IBM Japan from 1985 to 1998. From 1998 to 2001 he was an associate professor at the Iwate Prefectural University, Japan. From 2001 to 2003, he was an associate professor at Kyoto University, Japan.

Plenary Lecture in Symposium on Simulation Technology for Safe, Secure and Resilient Society Cyber-physical System and Industrial Applications of Large-Scale Graph Analysis and Optimization Problem Katsuki Fujisawa, Professor Institute of Mathematics for Industry, Kyushu University Artificial Intelligence Research Center, Advanced Industrial Science and Technology Global Scientific Information and Computing Center, Tokyo Institute of Technology Research Center for Statistical Machine Learning, The Institute of Statistical Mathematics

Abstract: In this talk, we present our ongoing research project. We have started the research project for developing the Urban OS (Operating System) on a large-scale city from 2013. The Urban OS, which is regarded as one of emerging applications of cyber-physical system (CPS), gathers big data sets of people and transportation movements by utilizing different sensor technologies and storing them to the cloud storage system. We have another research project whose objective is to develop advanced computing and optimization infrastructures for extremely large-scale graphs on post peta-scale supercomputers. For example, our project team was a winner of the 8th and 10th to 14th Graph500 benchmark. The Urban OS employs the graph analysis system developed by this research project and provides a feedback to a predicting and controlling center to optimize many social systems and services.

Invited Talks

Invited Talk #1 in Symposium: New Development of Simulational Science in Statistical Physics Nonequilibrium relaxation method in random systems Tota Nakamura Shibaura Institute of Technology

Abstract: A system with random interactions shows many exotic and nontrivial phenomena. However, its simulation studies are plagued by severely slow dynamics. Various algorithms have been proposed to accelerate the dynamics. However, we still cannot reach a conclusion of the spin-glass transition, which is a problem of random magnets first investigated more than 30 years ago. In this talk, we introduce an alternative approach to investigate such slow-dynamic systems, namely a non-equilibrium relaxation method. This method uses data in a non-equilibrium relaxation process that have been discarded in the conventional equilibrium method. The slow dynamics caused a waste of computational time but it now

becomes an advantage because we can use more data. It can be regarded as an exchange of size and time limit to the thermodynamic limit as shown in the figure. Its application to the spin-glass problem coupled with the Bayesian inference successfully clarified the phase transition relevant to the real spin-glass materials.

Biography: Prof. Tota Nakamura is currently a professor at the school of arts and sciences, Shibaura Institute of Technology, Japan. His research interest includes a phase transition in random magnets, developments of new simulation algorithms and Bayesian inferences. He received his B.S., M.S. and Ph.D. degrees in physics from Tokyo Institute of Technology, Japan in 1988, 1990, and 1993, respectively. From 1993 to 1995, he was a post-doc researcher at the University of Tsukuba, and research associate at the Tohoku University from 1995 to 2004. From 2004 to 2010, he was an associate professor at Shibaura Institute of Technology, Japan.

Invited Talk #2 in Symposium: New Development of Simulational Science in Statistical Physics Emergence of Antiferroelectric Phase in Spheroidal Dipolar Particles Kyohei Takae Institute of Industrial Science, University of Tokyo

Abstract: We demonstrate ferroelectricity and antiferroelectricity in crystals composed of spheroidal dipolar particles by varying the aspect ratio of the particles. We perform molecular dynamics simulations to study phase behavior, where the electrostatic dipolar inter-action is calculated by smooth particle mesh Ewald method. We obtain phase diagram of the system by calculating the chemical potential of liquids, paraelectric crystals, ferroelectric crystals, and antiferroelectric crystals. It is found that the ferroelectric phase is realized for the particles with aspect ratio close to unity, whereas antiferroelectric phase is realized for large aspect ratio.

Invited Talk #3 in Symposium: New Development of Simulational Science in Statistical Physics Simulations of word popularity dynamics observed from large scale social data Kenta Yamada National Institute of Informatics, JST Presto

Abstract: We show the dynamics of frequency of trending words observed from a large- scale blog database, which are characterized by an exponential function and a power function. We reproduce these dynamics by an agent-based model based on the SIR (Susceptible- Infected-Recovered) model which is well known in mathematical epidemiology to clarify the origin of these dynamics from the view point of bloggers interactions. In our social model, we introduce a “ground”, “excited” and “final” state respectively instead of susceptible, infected and recovered state. Agents move from the ground state to the excited state and from the excited state to the final state according to transition probabilities. Our model reasonably reproduces the dynamics observed from our data. In addition we applied our model to analysis of false rumor spreading.

Invited Talk in Symposium: Numerical Simulation and Visual Analytics of Nonlinear Problems Energy-Based Multiscale Modeling of Magnetic Material Tetsuji Matsuo, Professor Kyoto University

Abstract: The development of magnetic-material simulator is a challenging task because of its multiscale nature where domain-wall behavior in nm-scale affects macroscopic property in mm/cm-scale. Based on mesoscopic magnetic-domain modeling in crystal-grain scale, we developed a physical multiscale model of magnetic material. It is an energy-based model that can take into account influence of physical factors in their energy forms. For example, the magneto-mechanical interaction can be analyzed by including the magneto-elastic energy as an energy component. The multi-scale model successfully reconstructed stress-dependent properties of silicon steel and magnetization properties of a thin-film magneto-impedance element. Magnetization analysis [Fig. 1(a)] of silicon steel under mechanical stress predicts the stress dependence of hysteresis loss [Fig. 1(b)], which quantitatively agrees with the measured loss.

Invited Talk in Symposium on Simulation Technology for Safe, Secure and Resilient Society Factors of Security Breach Noriko Yamashita Cybersecurity Advisory, KPMG Consulting

Abstract: Today we hear Cyber attacks news all around the world. And in Japan, we recently had major PII breach in June, 2015. In this talk, I will examine the factors of Security Breach focusing on 3 major factors why breach happens when Cyber attacks hits corporations. Companies can make effort to protect

against from Cyber attacks but with attackers growing sophisticated more and more there is no single bullet for Cyber attacks. By focusing on the factors of security breach we can help the corporations to limit the damage of security breach at minimum if not none. Three 3 major factors: People, Process, and Technology.

Tutorial in Symposium: New Development of Simulational Science in Statistical Physics Worldline Monte-Carlo methods of huge systems Akiko Masaki-Kato RIKEN

Abstract: The quantum Monte Carlo method based on the Feynman’s path integral representation, called the worldline Monte Carlo method, is a numerical method for exactly solving large quantum many-body systems in the field of statistical physics. The worm algorithm is one of most effective algorithm for globally updating the worldline configuration and this algorithm has wide range of applicability to quantum magnets (i.e. quantum spin systems) and bosonic particles in lattice systems. In this talk we will introduce the basics of the worldline Monte Carlo method and recent developments of the worm algorithm for huge systems. We will show the benchmark of a worm algorithm with the nontrivial parallelization for the bosonic particles in huge two-dimensional square and three-dimensional cubic lattices.

Introduction to Visualization System, KVS Kyoko Hasegawa College of Information Science & Engineering, Ritsumeikan University

Abstract: Kyoto Visualization System (KVS) is a multi-platform, open source C++ Toolkit for developing scientific visualization applications. KVS provides useful classes to quickly implement surface rendering, volume rendering, particle-based rendering, and others. KVS users are required to have knowledge on C++ languages, but not on OpenGL, GPU, or details of volume-rendering algorithms. In this tutorial, we show how to implement visualization applications using KVS by examples such as volume rendering, surface rendering and fused visualization (These figures show examples of particle-based rendering created by using KVS).

Tutorial in JSST Student Research Symposium Construction of muscle activity model based on Bayesian network and kinematic evaluation Jun Inoue Tokyo Denki University

Abstract: We build foot muscular activity model based on Bayesian network and evaluate kinematic aspect. We aimed to enable quantitative selection of lower foot orthoses based on a patient’s muscular activity in the lower foot. Physical models require three dimensional motion analy-sis and force plate. These measurement systems cannot be used clinically, so they are not suitable for making these clinical use. Therefore, we chose Bayesian network to construct a model for estimating the muscular activity from parameters that can be measured easily, such as joint angle and sole pressure. Here, we verify the kinematic validity of the model parent node for foot muscles.

Biography: Jun Inoue received him PhD in engineering from the Waseda University, Japan, in 2013. He is currently an assistant professor at Tokyo Denki University.
