Academia and Entrepreneurship: How to Start and Run a Technology Company
Zbigniew Michalewicz

The process of building a business “from rags to riches” is never easy, but there are many tips and techniques that can be used to smooth some of the bumps in the road. The only thing better than learning through your own personal experience is learning from someone who did it. During the talk we would discuss many of such tips and techniques that are often lost among the myriad of issues that emerge during the journey of growing business. The fundamental question we would address is "What should I do to make people believe in my business?" The talk will be illustrated by presenting a few selected projects and additional insights.

Computational Intelligence for Brain Computer Interface (CIBCI)
Chin-Teng (CT) Lin

Brain-Computer Interface (BCI) enhances the capability of a human brain in communicating and interacting with the environment directly. BCI plays an important role in natural cognition, which concerns the studies of brain and behavior at work for enhancing or restoring cognitive functions. BCI is widely considered a ‘disruptive technology’ for the next-generation human-computer interface in wearable computers and devices. Many people may benefit from BCI, which facilitates continuous monitoring of fluctuations in cognitive states under monotonous conditions in workplace or at home. People who suffer from episodic or progressive cognitive impairments in daily life can also benefit from BCI. In this tutorial, I will first introduce the current status of BCI and its major obstacles: lack of wearable EEG devices, various forms of noise contamination, user/circadian variability, and lack of suitable adaptive cognitive modeling. I will then introduce some methodologies to overcome these obstacles, including discovering the fundamental physiological changes of human cognitive functions at work and then utilizing these main bio-findings and computational intelligence (CI) techniques to monitor, maintain, or track human cognitive states and operating performance. In the second part of the tutorial, I will introduce an innovative BCI-inspired research domain called Cyber-Brain-Physical Systems. Some future research directions in this domain will be explored and discussed, including BCI-embedded wearable computing, BCI-based neuro-prosthesis and assistive devices, wearable cognitive robots, and BCI-empowered training. The potential real-life applications of BCI on various aspects of training/education, healthcare, rehabilitation, and medical treatment will also be introduced and discussed.

Methods and Techniques for Combating False Information in Social Media
Wei Gao

Traditionally, fact-check of news stories follows investigative journalism which requires significant amount of time and manual effort. With the deep penetration of social media in our daily lives, large number of news updates disseminated widely can be generated from unreliable or unverified information sources. This renders conventional fact-checking effort increasingly ineffective, evidenced as massive-scale circulation of rumors and fake news online, which has become a serious phenomenal issue in recent years. In this tutorial, I will introduce automatic approaches, techniques and their new development for combating false information online especially in social media from the perspective of natural language processing and machine learning. I will focus on the characterization of rumours and fake news, their linguistic, temporal and propagational patterns and dynamics, as well as the effective machine learning models for detecting, tracking and classifying rumorours events. The tutorial will conclude with takeaways from past and ongoing research, and discuss potential future directions.

Dr. Wei Gao is currently a Senior Lecturer in the School of Information Management, Victoria University of Wellington. Previously, he held positions as Scientist in Qatar Computing Research Institute, Research Assistant Professor in the Chinese University of Hong Kong, and Research Fellow in the Institute for Infocomm Research in Singapore. His research interests include information retrieval, natural language processing, social media analytics, and artificial intelligence. His publications appear in the major international conferences and journals including ACL, EMNLP, SIGIR, CIKM, WSDM, IJCAI, ACM TOIS, ACM TIST, etc. He is a Senior PC member of AAAI 2019 and has served in the program committees of many other top-tier conferences.

Managing and Communicating Object Identities in Knowledge Representation and Information Systems
David Toman and Grant Weddell

A referring expression in linguistics is any noun phrase identifying an object in a way that will be useful to interlocutors. In the context of knowledge representation and information systems constant symbols occurring in an underlying knowledge base are the artifacts usually used to identify a subset of the objects for which the knowledge base captures knowledge.

This tutorial explores how objects that can be usefully identified can be extended by allowing more general formulas in the underlying language of the knowledge base, called singular referring expressions, to replace constants as syntactic identifiers of such objects. Expanding the possibilities of identifying (possibly implicitly defined) objects serves numerous purposes, ranging from allowing query answers to contain additional tuples (which are typically eliminated due to lack of constant symbols denoting components of such tuples), to answers that are more informative, to decisions on how to communicate references to objects among various cooperating agents, to identification issues related to physical data representation in computer storage (such as relying on addresses in main-memory databases).

Dr. David Toman and Dr. Grant Weddell are professors of Computer Science at the University of Waterloo, Canada. Together with Alexander Borgida (Rutgers), they have introduced referring expressions in the area of Ontology-based data access (OBDA) and received the Ray Reiter Best Paper prize at KR 2016 for this work. They subsequently extended this work to the area of conceptual modelling and other areas connected with ontological reasoning and knowledge representation. They have published and presented results in the area of knowledge representation over the last 20 years at premier AI conferences (including another Reiter prize in 2010); Dr. Toman has also given tutorials in the area of temporal representation and reasoning that led to an invited chapter in the Handbook of Temporal Reasoning in Artificial Intelligence.

Evolutionary Computation for Digital Art
Frank Neumann and Aneta Neumann

Evolutionary algorithms have been used in various ways to create or guide the creation of digital art. In this tutorial we present techniques from the thriving field of biologically inspired art. We show how evolutionary computation methods can be used to enhance artistic creativity and lead to software systems that help users to create artistic work. We start by providing a general introduction into the use of evolutionary computation methods for digital art and highlight different application areas. This covers different evolutionary algorithms including genetic programming for the creation of artistic images. Afterwards, we discuss evolutionary algorithms to create artistic artwork in the context of image transition and animation. We show how the connection between evolutionary computation methods and a professional artistic approach finds application in digital animation and new media art, and discuss the different steps of involving evolutionary algorithms for image transition into the creation of paintings. Afterwards, we give an overview on the use of aesthetic features to evaluate digital art. The feature-based approach complements the existing evaluation through human judgments/analysis and allows to judge digital art in a quantitative way. Finally, we outline directions for future research and discuss some open problems. The tutorial will contain various animations to showcase digital art. We also plan to allow the audience to interact with recent computer systems for digital art.

Machine Learning in Uncertain Environments
Ke Tang

Machine learning have been shown to be a powerful technique for intelligent data analytics. Due to the inherent uncertainty associated with the environments, most real-world data are subject to various uncertainty, such as non-stationary data distribution, noisy labels and uncertain misclassification costs, which brought great challenge to machine learning. This talk will introduce how standard machine learning techniques, especially ensemble learning, could be adapted to address the above challenge.

Ke Tang is a Professor at the Department of Computer Science and Engineering, Southern University of Science and Technology (SUSTech). Before that, he was with University of Science and Technology of China, first as an Associate Professor (2007-2011) and then a full Professor (2011-2017).

Grammar-Guided Genetic Programming
Grant Dick and Peter Whigham

Genetic programming (GP) is an evolutionary computation method with a focus on representations using an arbitrary length data structure. Relaxing the need for an upfront selection of solution size and shape allows GP to explore a rich space of solutions. However, most variants of GP require some form of closure, where each subcomponent of a solution must be freely interchangeable with any other subcomponent. The incorporation of a grammar into GP allows it to maintain a flexible structure for its representation, but also frees GP from its closure requirement and allows GP to factor in domain knowledge and bias.

In this tutorial, we will provide a brief introduction into grammar-guided GP, including the historical development of the method, an overview of its primary operators, and highlight some useful and interesting applications. We will also provide a brief overview of the current trends in grammar-guided GP, centred mainly along the lines of appropriate design of representation and associated search operators.

Dr. Grant Dick and Associate Professor Peter Whigham both hail from the Department of Information Science, University of Otago, where they teach into the data science undergraduate and postgraduate classes. Both have a long track record in genetic programming, with a combined experience of 40 years' research into GP methods. They have a particular interest in theoretical aspects of GP (e.g., the phenomenon of bloat, and fine-grained evaluation of GP fitness) as well as applying GP methods in evolutionary machine learning. Outputs of their work have been published in IEEE Transactions on Evolutionary Computation, Genetic Programming and Evolvable Machines, along with the conferences GECCO and CEC.
