  • We discuss the interplay between Data Science and Data Engineering and how both must combine to power the Big Data Revolution
  • We review the different aspects of data engineering needed to process large scale data and how it is implemented in the Cylon and Twister2 systems to support deep learning and Python notebooks. and
  • We give application examples from COVID-19 daily data, solutions of ordinary differential equations, and other fields of science generating geospatial time series.
  • We show how working with the industry consortium MLPerf, we may be able to establish a collection of science data benchmarks demonstrating best practices and motivating the next generation cyberinfrastructure

To meet the needs for energy savings in Internet of Things (IoT) systems, solar energy has been increasingly exploited to serve as a green and renewable source to allow systems to better operate in an energy-efficient way. In this respect, accurate photovoltaics (PV) power output prediction is a prerequisite for any energy saving scheme employed in these systems. In this talk, I am going to discuss a unified training framework combined with the LightGBM algorithm to obtain a prediction model, which can provide short-term predictions of PV power output. Compared with the training in a single powerful machine, our proposed framework is more energy-efficient and fits into devices with limited computation and storage capabilities. The experimental results show that our proposed framework is superior to other benchmark machine learning algorithms.

Cloud computing has been established as an effective computing paradigm in science and business and many applications have been moved from traditional computing infrastructures to the cloud. Consequently, issues related to cloud resource allocation, application scheduling, timeliness, energy efficiency and cost have been important research areas. Particularly important in cloud computing is to run real-time applications. Effective scheduling techniques should be utilized ensuring that the deadlines will be met.

In recent years, smart devices and sensors have been widely adopted in many domains of life, contributing to the expansion of the Internet of Things (IoT). IoT applications generate huge amounts of data and most of them are real-time applications with hard deadlines. As a result, fog computing has appeared as a computing model extending the cloud to the edge of the network, thus reducing the latency of IoT data transmission and avoiding network congestion. The computational capacity of fog resources is usually limited, therefore appropriate scheduling of real-time applications is required to fully exploit the capabilities of cloud and fog computing ensuring QoS to the end users.

Towards this direction, in this keynote we will describe techniques and solutions to address challenges in scheduling real-time applications in cloud and fog computing platforms and we will conclude with future research trends in the cloud and fog computing areas.

The booming growth and rapid development in embedded systems, wireless communications, sensing techniques and emerging support for cloud computing and social networks have enabled researchers and practitioners to create a wide variety of Cyber-Physical-Social Systems (CPSS) that reason intelligently, act autonomously, and respond to the users’ needs in a context and situation-aware manner. The CPSS are the integration of computation, communication and control with the physical world, human knowledge and sociocultural elements. It is a novel emerging computing paradigm and has attracted wide concerns from both industry and academia in recent years.

Currently, CPSS are still in their infancy stage. Our first ongoing research is to study effective and efficient approaches for CPSS modeling and general system design automation methods, as well as methods analyzing and/or improving their power and energy, security, trust and reliability features.

Once the CPSS have been designed, they collect massive data (Volume) from the physical world by various physical perception devices (Variety) in structured/semi-structured/unstructured format and respond the users’ requirements immediately (Velocity) and provide the proactive services (Veracity) for them in physical space or social space. These collected big data are normally high dimensional, redundant and noisy, and many beyond the processing capacity of the computer systems. Our second ongoing research is focused on the Big Data-as-a-Service framework, which includes data representation, dimensionality reduction, incremental and distributed processing, security and privacy, deep learning, clustering, prediction and proactive services, aiming at representing and processing big data generated from CPSS, providing more valued smart services for human and refining the previously designed CPSS.

This talk will present our latest research on these two directions. Corresponding case studies in some applications such as smart traffics will be shown to demonstrate the feasibility and flexibility of the proposed system design methodology and analytic framework.
