Research in modeling, analyzing and mining large-scale networks has attracted an increasing effort in the last few years. A major trend of work in network modeling and mining concerns analyzing homogeneous static networks (i.e. one snapshot of a network). However, in real world settings, networks are often dynamic, heterogeneous, and both nodes and links can be described by a set of attributes. To cope with that problem, two current main trends are explored in our tutorial: multiplex networks and attributed networks analysis approaches.

A multiplex network is often represented as a multi-layer network composed of a set of nodes related to each other with different types of relations. This representation is much richer than simple monoplex networks. However, this poses the challenge to provide adequate answers to all basic network analysis tasks that have been studied and provided in the recent few years. Almost all work in the field of multiplex and attributed network analysis are based on transforming the problem, in a way or another to the classical case of homogeneous network analysis. In this tutorial, we focus mainly on new approaches that extend existing approaches to new rich representations of multiplex and attributed networks, and provide an organized picture on analytical methods, also including exemplary applications.

Title: Collecting Data with Serverless Applications

The success of data science algorithms highly depends on the quality of the available data. In the last decades, harnessing the power of the crowd in collecting and cleaning data became one sure way of increasing the quality of the data used in machine learning algorithms. In this tutorial, we present a methodology for developing and deploying data collecting applications on serverless platforms, which allow full control on each component of the application. The cost of deploying and operating the resulting application is virtually zero, due to the generous free tiers in serverless platforms. In comparison, a popular crowdsourcing platform would incur a significant cost to host the same application. This novel way of developing and deploying applications is made possible by a new cloud computing technology called serverless.

The basic concepts of serverless computing will be taught and a concrete example of a data collecting application will be presented. The final product of the tutorial will be an online web application that can collect, clean and store data. Each of the participants will be able to have their own application up and running by the end of the tutorial. The tutorial will use the open source Apache OpenWhisk serverless platform (http://openwhisk.incubator.apache.org/) with its offering in IBM Bluemix.

Intended Audience: Anyone with an interest in data collection. Basic programming skills are required.

Recently a new morphometric statistical analysis using clustering approach has been growing. This analysis was developed by the University of Leeds in 1998 called statistical shape analysis or commonly known as geometric statistics [1, 2]. Using this statistical analysis we can measure the change in the shape of an object or so-called deformation, easily. The problem on transforming data sets in the different size, orientation and shape of an object into a coordinate system is very difficult, over years. Coordinate system is called as register mark or landmark then. By this analysis, we can be quantified the shape of an object by eliminating information of location, rotation, and scale. However, the mathematics is difficult to understand. To solve the problem, first we will explain the math process visually. Visualization has the power to make people understand the content meaning at a glance. The visualization power is required in mathematics education. We have developed and used many visual teaching materials in our university math lectures. Using the teaching materials, we have done the tutorial lectures in PRICAI 2016 (http://aiat.in.th/pricai2016/front/show/tutoriallist) and VINCI 2015 [3]. This time, we have been developing the teaching materials for the statistical shape analysis. We would like to show our teaching materials and explain the mathematics visually and interactively. The materials will be soon published on web. Therefore the audience can in advance access the visual materials with the free software “Wolfram CDF player.” We hope that more people who need and study the shape analysis mathematics easily understand and enjoy mathematics visually.
