Keynote & Invited Speeches
Many fields, like physics, neuroscience, chemistry, and sociology, investigate phenomena by processing multivariate measurementsadvantageously represented as a sequence of attributed graphs. Graphs come in different forms, with variable attributes, topology, and ordering, making it difficult to perform a mathematical analysis in the graph space. Within this framework, we are interested in processing graph datastreams to solve applications e.g., detect structural changes in the graphsequence, a situation associated with time variance, faults, anomalies or events of interestas well as design sophisticated processing like those requested by predictors.
On the change detection front, theoretic results show that, under mild hypotheses, the confidence level of an event detected in the graph domain can be associated with another confidence level inan embedding space; this enables the identification of events in the graph domain by investigating embedded data. The opposite holds. However, evaluation of distances between graphs and identification of an appropriate embedding for the problem at hand are far from being trivial tasks with deep adversarial learning approaches and constant curvature manifold transformation showing to be appropriate transformations able to solve the problem. Deep autoregressive predictive models can then be designed to operate directly on graphs, hence providing the building blocks for other future sophisticated neural processing.

Evolutionary Computation (EC) encapsulates a class of stochastic optimisation algorithms, which are inspired by principles from natural and biological evolution. EC has been widely used for optimisation problems in many fields. Traditionally, EC methods have been applied for solving static problems. However, many real world problems are dynamic optimisation problems (DOPs), which are subject to changes over time due to many factors. DOPs have attracted a growing interest from the EC community in recent years due to the importance in the real-world applications of EC. This talk will first briefly introduce the concept of EC and DOPs, then review the main approaches developed to enhance EC methods for DOPs, and describe several detailed approaches developed for EC methods for DOPs. Finally, some conclusions will be made based on the work presented and the future work on EC for DOPs will be briefly discussed.
In the current era of information overload, most of the datasets are high dimensional and often consist of many irrelevant and redundant features, thus making it complex and less efficient to model and analyze the data. It is, therefore, necessary to reduce the number of features required to achieve high classification performance. The feature selection algorithm looks for the optimal or most informative features by putting aside the redundant and irrelevant features, retaining accurate information and data structures where possible, resulting in efficient and more accurate predictive models. Various feature selection techniques have been developed and are continually nurtured to meet the evolving needs. This talk is intended to explore and analyze the effectiveness of Monte Carlo Tree Search (MCTS) in feature selection. MCTS is a dynamic search strategy and have proven its effectiveness in gaming domains with huge search spaces. MCTS finds the optimal solutions probabilistically by using lightweight random simulations. The feature selection task is modeled with a binary tree and modified MCTS is applied to the tree to select effective feature subsets. The proposed algorithms efficiently search the feature space and find the best feature subset within a few iterations to achieve high classification accuracy and reduced dimensions.

In this talk, recent industrial applications of AR technology will be surveyedafter reviewing the smart glasses for industrial augmented reality (AR) in practice. As a case study of industrial AR, aircraft maintenance with AR has been researched for many years as a research project and is now being commercialized with newsmart glasses by Augmented Knowledge Corp. This initial research project was started collaboratively between Inha University and University of Southern Californiain 2008, which is funded by Korean Air and Airbus.
Aircraft maintenance and training play one of the most importantroles and symbolicapplications of digital transformation in the fourthindustrial revolutions as well as for digital twin paradigm.The maintenance process usually involves massive numbersof componentsand substantial knowledge of maintenance procedures. Maintenance tasks require technicians to follow rigorous proceduresto prevent operational errors in the maintenance process. In addition, the maintenance time is a cost-sensitive issue for airline carriers. In this research, intelligent augmented reality (IAR) system is implemented to minimize operation errors and time-related costs. This system alsohelp aircraft technicians cope with complex tasks by using an intuitive interface such as gestures, eye tracking and voice recognition fortheir maintenance tasks. A unified platform between computer vision and knowledge was invented for integrating computer vision with knowledge. Knowledge is introduced to deals with the various manuals which should be updated periodically. Overall testing of the IAR system is conducted at Korea Air Lines (KAL)hangars. According to the benchmark, theIAR system can help technicians to be more effective and accurate in performing their maintenance tasks, reduces the maintenance time about 30%.IAR-MAP which is a commercial version of IAR system provides a AR platform for B2B, which can integrate AR contents with the traditional legacy systems such as ERP and MRO.

Dialog agent, which is also known as Chatbot, is recently attracting much attention from industrial fields and academic fields. The dialog agent takes a text or speech from users as an input, and gives a response text or synthesized voice. This provides a new way of interaction (e.g., voice or natural language text), and it can be applied to various industrial products (e.g., speaker, TV, search system). The change of interaction way is now reaching to its next step incorporating visual factors.
Mixed reality (MR) is a mixture concept of Augmented reality (AR) and Virtual reality (VR), and it allows the users to look at and interact with the visual agents. We design a dialog agent in the MR environment. Although the dialog agent is a virtual object, it has a indoor position in the real-world; we may interact with the agent when we are close enough to the agent. We believe that the dialog agent in MR environment has much potential to various industrial fields such as amusement park, education services, and healthcare services.
