Chair: Prof. Yeong-Luh Ueng

Abstract: Financial technology (Fintech), a broad category that refers to the innovative use of ICT technology in the design and delivery of financial services and products, as revolutionized the financial industry or even more broadly the service industry. Artificial intelligence (AI) is the intelligence demonstrated by machines, in contrast to the natural intelligence (NI) displayed by humans and other animals. The tremendous success of AI and machine learning algorithms in the area of computer vision and natural language processing has demonstrated great potential of further applications into other disciplines. One of the most promising areas is the use of AI, machine learning, and financial data analytics in FinTech. In this tutorial, we will first introduce the financial concepts in the context of ICT and then aim to provide an overview of the recent trends in Fintech, machine learning and statistical signal processing approaches for tackling important challenges in FinTech, and how such approaches can be applied to solve real-world problems. We will discuss the challenges, constraints, and opportunities in this fascinating research area.

Title: Generative Adversarial Network and its Applications to Speech Signal and Natural Language Processing

Speaker: Prof. Hung-yi Lee, National Taiwan University

Chair: Prof. Che Lin

Abstract: Generative adversarial network (GAN) is a new idea for training models, in which a generator and a discriminator compete against each other to improve the generation quality. Recently, GAN has shown amazing results in image generation, and a large amount and a wide variety of new ideas, techniques, and applications have been developed based on it. Although there are only few successful cases, GAN has great potential to be applied to text and speech generations to overcome limitations in the conventional methods. There are three parts in this tutorial. In the first part, I will give an introduction of GAN and provide a thorough review about this technology. In the second part, I will focus on the applications of GAN to speech signal processing. In the third part, I will describe the major challenge of sentence generation by GAN and review a series of approaches dealing with the challenge.

Tutorial V

Title: Making Healthcare More Accessible via AI: Extension of Telemedicine

Speaker: Prof. Gwo Giun (Chris) Lee, National Cheng Kung University

Chair: Prof. Yuan-Hao Huang

Abstract: This tutorial will focus on innovative digital health ecosystem and analytics system which fosters extension of telemedicine through the transfer of comprehensive medical expertise and experiences via Artificial Intelligence (AI) from tertiary medical centers to remote care facilities in making healthcare more accessible! Cancer is among the most important issues of healthcare worldwide. However, under current medical systems, diagnosis of these severe diseases is commonly delayed, especially in remote locations with limited medical resources. Hence it is necessary to facilitate early screening at these distant care units using Computer-Aided-Diagnostic (CAD) tools possessing tertiary centers’ experiences accumulated through AI. In attempts to reform and advance the digital health environment, using skin care as example, this tutorial introduces an ecosystem, by which integration of remote care facilities is substantiated, through utilization of high accuracy and efficiency of AI as extension of telemedicine! Being an exemplary, this AI medical networking model is readily extensible to global medical and biotech communities! This tutorial will also introduce the speaker’s reconfigurable edge system for the detection of Skin Cancer on mobile devices with more than 95% accuracy.

Tutorial VI

Title: Tensor Subspace Analysis in Signal Processing

Speaker: Prof. Yipeng Liu, University of Electronic Science and Technology of China

Chair: Prof. Wei-Ho Chung

Abstract: The standard matrix computation can not fully exploit the global data structure in higher-order signal processing. The recent advances in tensor computation allow us to move from classical matrix based methods to tensor based methods for many signal processing techniques. This tutorial focuses on different tensor decompositions for tensor subspace analysis in signal processing. Firstly, a basic coverage of tensor notations, preliminary operations, and main tensor decompositions is briefly provided. Based on them, a series of tensor subspace analysis methods are presented, as the multi-linear extensions of classical sparse signal recovery, principle component analysis, matrix completion, non-negative matrix factorization, linear regression, subspace cluster, etc. The experimental results for some signal processing applications are given, e.g., image reconstruction, denoising, illumination normalization, background extraction, and classification. Finally, some deep tensor networks are discussed for possible tensor signal processing applications.
