  Speech Title: openGauss: An Autonomous Database System

  Abstract: In this talk, I will present how to build an autonomous database system. I discuss how to integrate effective learning-based models into database systems to build learned optimizers (including learned query rewrite, learned cost/cardinality estimation, learned join order selection and physical operator selection) and learned database advisors (including self-monitoring, self-diagnosis, self-configuration, and self- optimization). I also propose an effective validation model to validate the effectiveness of learned models. I discuss effective training data management and model management platforms to easily deploy learned models. Finally I will introduce our autonomous database system openGauss.

Geoff Webb is a leading data scientist. He is Research Director of the Monash University Data Futures Institute and a Technical Advisor to data science startups FROOMLE and BigML Inc. The latter have incorporated his best of class association discovery software, Magnum Opus, as a core component of their advanced Machine Learning service. He developed many of the key mechanisms of support-confidence association discovery in the late 1980s. His OPUS search algorithm remains the state-of-the-art in rule search. He pioneered multiple research areas as diverse as black-box user modelling, interactive data analytics and statistically-sound pattern discovery. He has developed many useful machine learning algorithms that are widely deployed. He has applied machine learning in a broad range of applications including manufacturing, finance, medicine, biology and geoscience. He was editor in chief of the premier data mining journal, Data Mining and Knowledge Discovery from 2005 to 2014. He has been Program Committee Chair of the two top data mining conferences, ACM SIGKDD and IEEE ICDM, as well as General Chair of ICDM. He is an IEEE Fellow. His many awards include the prestigious inaugural Australian Museum Eureka Prize for Excellence in Data Science. His 250+ academic papers have received over 14,000 citations with an h-index of 60. Seven of his recent papers have been recognised as Clarivate Web of Science High Cite papers (top 1% of citations for the discipline).

  Speech Title: Recent Advances in Assessing Time Series Similarity Through Dynamic Time Warping

  Abstract: Time series are a ubiquitous data type that capture information as it evolves over time. Dynamic Time Warping is the classic technique for assessing degrees of similarity between time series. This talk outlines our impactful program of research that has transformed the state of the art in practical application of Dynamic Time Warping to big data tasks, including fast and effective lower bounds, fast dynamic programming methods for calculating Dynamic Time Warping, and an intuitive and effective variant of Dynamic Time Warping that moderates its sometimes-excessive flexibility.

  Speech Title: Data Systems in the New World of Device-Edge-Cloud Computing

  Abstract: The rapid growth of wireless mobile broadband communication networks has fueled new capabilities in scalable device-to-edge-to-cloud continuum, ranging from increased data rates of 1~10 Gbps, ultra-low latencies of 1ms or less, larger coverage with massive number of devices connected 24x7. These advances have enabled exciting new edge native applications, such as Augmented Reality/Virtual Reality (AR/VR) and video analytics. However, unlike Clouds, edge clients have little elasticity in computing and communication resources, are intermittently connected to the Internet, inherently heterogeneous in computing resource, and more exposed to privacy and security violations. In this keynote, I will use edge video analytics and federated learning as two emerging and complimentary distributed learning paradigms in navigating this device-edge-cloud continuum, while considering resilience, privacy, and multi-tenancy of shared and heterogeneous resources. I will describe alternative distributed learning architectures and optimization strategies, enabling edge system adaptability and robustness, while preserving good application fidelity (level of accuracy).
