Information Technology & Machine Learning
The tremendous success of machine learning and deep learning in complicated problems has been accomplished for last ten years. Starting from the AlphaGo from Google deepmind to notoriously well-known problems in image classification, image recognition, voice regeneration, text generation, and speech recognition, they cannot be modelled and resolved by a classical scientific methodologies and numerical algorithms but smart neural networks with recently developed methodologies such as generative adversary network, variational autoencoder, and recurrent neural network can provide incredibly plausible solutions. It is certainly great success in engineering and application field. However, in machine learning (data-driven modelling ), there are some unsettled factors which cannot be completely understood in a modeling point of view. It is strongly related to fidelity and safety in many applications. In the following sessions, we aim to understand the nature of machine learning, not to only review fancy examples which work very well in applications. Three groups in South Korea which are dedicated to industrial mathematics (industrial & mathematical data analytics research center in Seoul national university, industrial mathematics center on big data in Pusan national university, innovation center for industrial mathematics, national institute for mathematical sciences) will organize the sessions for industrial and applied mathematics in machine learning. The other three sessions are organized by Dr. Kab Seok Kang (Max-Planck Institute for Plasma Physics, Germany), Dr. Young Saeng Park (University of Warwick, UK), and Dr. Sogkyun Kim (Rolls-Royce plc, UK). The topics are high performance computing, Advanced Automation for Industry 4.0, and big data in aerospace & automotive engineering.

Machine learning techniques reach to human-level ability in some applications of image and speech recognition recently. The research and development of machine learning algorithms are being expanded in various real-world problems such as communication, security, non-destructive evaluations, medical sciences, that are highly related to nowadays human life. Last decades, various mathematical theories and numerical techniques have been investigated to solve various inverse problems related to medical imaging science and non-destructive evaluations. However, the corresponding problems in many cases are highly nonlinear and ill-posed, with modeling inaccuracies and data uncertainties, which make them difficult to solve and obtain desired results. Machine learning has the potential to deal with these nonlinear and ill-posed problems. It turned out that the accuracy (or decision) of algorithms becomes increasing when one has appropriate training process and enough training data. For this, understanding of modeling inaccuracies, intrinsic data uncertainties, and measurement data process are needed. So, development of an effective machine learning technique to the problem at hand and corresponding mathematical theories must be considered in early stages. In this session, we bring together researchers to present recent results related to inverse problems and deep learning technique in biomedical imaging.

Applied and industrial mathematics are fields that not only Korean and European government, but almost all countries around the world actively and primarily support to better face the dawn of the 4th industrial revolution. Therefore, it is required to develop an appropriate system to identify, evaluate and diagnose the problems that the affected industries need to solve for the advancement and sustainable growth of world infrastructure. Here though, in order to develop such system, customized mathematical expertise is desperately needed. Nevertheless, as of now it is very rare to utilize math specialists in the current affected industries. In addition, due to the absence of a program that links mathematics with such industries, there are barriers in communication. Therefore, it is time to build a customized applied and industrial mathematics education program and revitalize the fields of applied and industrial mathematics to foster applied and industrial mathematicians with specialized expertise in the world. In order to achieve this, there is an urgent need for active exchanges between experts in applied and industrial mathematics in Europe and Korea. In particular, the exchange with Korean researchers in Europe is at the core. Therefore, in this special session of EKC 2018, we invite the best researchers of applied and industrial mathematics in Europe and they will introduce the recent research trends. Also we will introduce the three industrial mathematics centres in Korea and discuss their roles and further, the general role of applied and industrial mathematics to prepare for the future of the 4th industrial revolution. Finally, we will consider the direction of research on artificial intelligence in Korea and how to promote exchanges with Europe and Korea in the future. Based on this, we want to investigate what kind of desirable roles and talents mathematics, which form the basis of Big Data, Artificial Intelligence, and IoT (Internet of Things) will engage in.

The multi-disciplinary session is a discourse on the current theories, methodologies, and applications of image and signal processing. Specifically, two themes are covered : "Deep Learning for Image Processing : Denoising, Deblurring, and Segmentation” (Theme 1) and "ICT Technologies for Emerging Biomedical Applications"(Theme 2). All who are interested in contributing to either theme are welcome to join. [Theme 1] This session is covered with the mathematical modeling in image processing. Image processing is a method to perform some operations on an image, in order to get an enhanced image or to extract some useful information from it. It is a type of signal processing in which input is an image and output may be image or characteristics associated with that image. Nowadays, image processing is among rapidly growing technologies. It forms core research area within engineering, computer science and applied mathematics. In this session, we will focus on the variational models and numerical methods for various image processing problems. We also investigate deep learning frameworks for image processing. In this session, we focus on the following image processing problems. 1. Image denoising: In many real applications, images unavoidably suffer from noise that occurs during the image-acquisition process. Thus, image denoising is essential in image processing, and it aims to remove noise while simultaneously preserving edges and fine details. 2. Image deblurring: In many applications, images corrupted by a blur and noises due to object movements, hand shaking and out of focus etc. Hence, its goal is to remove blurring and noise while conserving small features and textural patterns. 3. Image segmentation: Image segmentation is a fundamental imaging problem. Its aim is to partition an image into several regions such that the image within each region has uniform characteristics, i.e., edges, intensities, color, and so on. We introduce mathematical modeling based on following approaches. 1. Modeling on variational approaches: To solve image processing problems, we often develop a minimization models based on variational approaches. Variational models have an objective function consisting of a data fidelity term and regularization term. We introduce a novel regularization term or a data fidelity term for each image processing problem. 2. Deep learning: Deep learning is part of machine learning methods based on learning data representations, as opposed to task-specific algorithms. It is very recent method, and gives remarkable results for image processing problems. [Theme 2] ICT and nanotechnology are now extending its contribution to the life sciences and biomedical applications. New concepts and services (e.g., point-of-care, patient-centered care, ubiquitous healthcare monitoring) have been initiated through smart sensors, wearable devices, and novel communication systems. The concept has made (and will make) a significant contribution to improving accuracy, and efficiency in diagnosis and treatment. In this session, experts with various backgrounds are welcomed to share their experience about how they addressed recent issues in biomedical applications.

Industrial companies are facing strong demand to increase their productivity and reduce their development cost due to the highly globalised market and competition. It is significantly important to adapt enhanced technologies for their success from different perspectives including product design to services for customers. Now, Industry 4.0 has brought not only boost efficiency but also increase effectiveness in order to respond customers’ demands. With the concept from Industry 4.0, it is possible to connect all levels in production and digitally map to all elements of the value chain using cutting-edge technologies such as cyber-physical systems, cloud computing, Internet of Things, machine to machine communication, etc. Companies should examine the benefit of Industry 4.0 and combine it with existing traditional method of production. Advanced automation in particular is one of key principles for Industry 4.0, considering many factors such as smart planning, smart machine, smart data, etc. It demands enhanced software tools to organise sophisticated processes and automate complex operations. It also requires smart machines which have capability to make a link to cloud systems and directly download the approved processing parameters to the machines. Furthermore, the real-time data obtained from production monitoring systems not only from the overall production but also an individual machine will help process-specific decision making and will become increasingly more important to companies. This session aims to look at the current trend and issue of advanced automation for Industry 4.0 as well as discuss on the new technologies with scientists and engineers from Korea and Europe. Participants may have opportunities to find collaboration partners working in the fields. Key words: cyber-physical systems, clouding computing, Internet of things, machine to machine communication, cognitive computing
