Abstract:

The idea of Data Science has gathered many different perspectives throughout different domains and articles. In this talk, Data Science is discussed as the theories, techniques, and tools designed for data-centered analysis and the methodology to apply them to real world applications. We have revolutionized the process of gathering multimedia data from an abundance of sources. Things such as mobile devices, social networks, autonomous vehicles, smart household appliances, and the Internet have increasingly grown in prominence. Correspondingly, new forms of multimedia data such as text, numbers, tags, networking, signals, geo-tagged information, graphs, 3D/VR/AR, sensor data, and traditional multimedia data (image, video, audio) have become easily accessible. Therefore, older traditional methods of processing data have become increasingly outdated, emphasizing the demand for more advanced data-science techniques to process these heterogeneous, large data sets which fluctuate in quality and semantics. Additionally, the inconsistencies of utilizing single modality severely hinders our ability to withstand multiple data sources simultaneously. Upon analyzing the capabilities of each model, it becomes pivotal for us to consider the multi-modal frameworks to leverage the multi-data sources to assist data analytics. With the implementation of data science and big data strategies, we are able to efficiently capture, store, clean, analyze, mine, and visualize exponential growth of multimedia data; which is responsible for the majority of daily Internet traffic. With the multimedia and data science fields growing with importance, the goal of big data revolution is to bridge the gap between data availability and its effective utilization which enables research, technological innovation and even decision making. In this talk, I will discuss the research opportunities and challenges in multimedia big data for data science. A set of core techniques will be discussed in details. I will also discuss how we apply our multimedia research to practical data science applications such as disaster information management.

Abstract:

Modern computing systems expand on the challenges of traditional monolithic applications by relying on a combination of servers, embedded and sensory devices, diverse architectural models, and various communication mechanisms to drive new ways of creating value and stimulating growth in diverse sectors of modern society. The fragmented and distributed nature of these systems, combined with the current shift towards continuous delivery and agile processes, call for advanced system analysis and fault diagnosis methods. Timely detection and prevention of crashes and anomalies are of paramount importance. This has led to a revival of interest in techniques and tools that operate on runtime data with a particular emphasis on log data. Logs describe a vast range of events observed at runtime, which can be the only reliable data sources for detecting and predicting system anomalies, diagnosing runtime problems, detecting security breaches, and demonstrating compliance with applicable regulations. In this talk, I will start by discussing the concept of system observability, which I present as the umbrella field for the current research that aim to gain insight into runtime data (traces, logs, profiling metrics, etc.). I will then dive into the research opportunities and challenges in system observability using log analytics with an emphasis on three aspects: the practice of logging, log analytics using machine learning and deep learning, and log governance and management. Finally, I will introduce the concept of Design for Observability, which reflects my vision on how to further improve the quality of contemporary software systems by bringing system observability to the early stages of the software development lifecycle.
