Title: The Intersection of Big Data, Data Science, and the Internet of Things

We are presently on the verge of an exciting new chapter in the Information Age. This chapter will be characterized by three disruptive technologies influencing how data is generated, distributed, and analyzed and by a struggle over how these technologies can be effectively managed and used. The technologies involved in this revolution are Big Data, Data Science, and the “Internet of Things (IOT).” Individually these fields have stirred great interest, but together they promise to change forever the ways we communicate, live our lives, conduct business, and acquire knowledge. This talk will explore both the potential and the pitfalls that need to be addressed in preparation for this convergence.

Brief biography:
Bebo White is a Departmental Associate (Emeritus) at the SLAC National Accelerator Laboratory, the U.S. national laboratory for high-energy physics and basic energy science at Stanford University. Working as a computational physicist, he first became involved with the emerging Web technology while on sabbatical at CERN in 1989.

Upon his return he was part of the team that established the first non-European Web site at SLAC (the fifth site in the world).

Title: Big Data and Stream Analytics

This talk is in two parts of unequal size. The first part covers the Big Data debate in terms of issues and challenges. The second, larger part, covers stream analytics. It provides an overview of the field with a focus on a University of Waikato open source project called MOA (Massive Online Analysis), this project is to stream mining what Weka is to non-stream mining. All theoretical work covered in the talk will have a corresponding implementation in MOA. In particular, I will present two recent results that indicate a need for caution and a statement of what constitutes state-of-the-art in data stream classification for practitioners. Finally, I will present the idea of experiment databases, a framework for data mining experimentation that saves effort and offers opportunities for meta learning and hypothesis generation. An example streaming application using MOA within the experiment database framework will be presented.

Timos Sellis

Speaker: Prof. Timos Sellis


Data ecosystems involve the coexistence of one or more data collections, typically databases, and their surrounding applications for data entry and retrieval. For decades, both data and ecosystem management have failed to address significant, costly and labor-consuming challenges which involve (a) the departure from databases focusing on alphanumeric data only, (b) their inability to be integrated and provide transparent access and composition facilities for heterogeneous data, (c) their static querying nature, which is deprived of personal, context-aware or interactive characteristics, (d) the enforcement of DBMS operation over monolithic servers, and, (e) the complete indifference to problems of evolution and adaptation over time.

In this talk we address issues around the methodologies, the theoretical and modeling foundations as well as the algorithmic techniques and the necessary software architectures that will facilitate the personalization, integration, and evolution management facilities for data ecosystems that operate over a decentralized infrastructure for a large variety of data types.

Ku Ruhana Ku Mahamud

Speaker: Prof. Ku Ruhana Ku Mahamud

Title: Hybrid ACS and Flower Pollination Algorithm for optimization

Nature is one of the best sources for inspiration to solve proble ms and several nature inspired algorithms have been proposed. One of these algorithms is the ant colony system which is based on the behaviour of real ant colony. The colony system algorithm is one of the best variants of the ant colony optimization algorithm. However, the exploration mechanism in ant colony system is not efficient specifically when the problem instance increases. A new hybrid algorithm between ant colony system and flower pollination algorithm for optimization problems is proposed. Two approaches which are based on the level of hybridization namely low level hybridization and high level hybridization are used in developing the hybrid algorithms.
