Title: Taming Big Data with Live Analytics

Abstract:

During the last decade we have witnessed a huge growth in data, up to 2.5 quintillion bytes of data created every day so far. This data comes from a variety of sources such as postings in social media sites, digital pictures and videos, traffic information from loop sensors, GPS signals from cell phones, stock exchange prices, purchase transaction records, to name a few. Big data never sleeps, it is a continually growing stream of digital activity pulsating through wires and air across the world. But big data is more than just a matter of volume, it is an opportunity to gain actionable insights from new and emerging types of data and content, left untapped by traditional business intelligence, to help companies make better business decisions and become more agile, effective and competitive. In this talk I will present some scenarios to motivate the need for a new kind of analytics platform, Live Analytics, capable of dealing with the new challenges that big data impose along the dimensions of volume, velocity and variety to deliver insights and predictive analytics within actionable time windows (i.e., "at the speed of business"). Examples of such scenarios include situational awareness, sentiment analysis, traffic impact prediction and activity monitoring in healthcare. Solutions built on top of Live Analytics need to integrate information of diverse data types from an increasing number of sources, handle explosive growth in data volumes, deal with rapidly updated content, and deliver shorter cycle times to quality decisions as well as a higher degree of automation. I will describe our perspective of the challenges that we have faced in building such solutions and the technologies built into the Live Analytics platform to support these novel requirements.

Biography:

Professor Malu Castellanos is a senior researcher and technical lead in the Information Analytics Laboratory at Hewlett-Packard Laboratories in Palo Alto, CA, USA. Since 1997 she has been applying information management and analytics technologies to develop intelligent solutions for different kinds of business related problems and novel techniques for different aspects of business intelligence. She received a B.S. in Computer Engineering at the National University of Mexico and a Ph.D. in Computer Science from the Polytechnic University of Catalunya. Prior to joining Hewlett-Packard she was on the faculty at the Information Systems Department of the Polytechnic University of Catalunya. She has 12 granted patents, 17 pending and more than 60 publications in international conferences, journals and book chapters. She has actively participated in numerous Program Committees (including VLDB, SIGMOD and ICDE), journal review boards and advisory boards and has held different leadership roles in the organization of several IEEE and ACM international conferences such as being General Chair of IEEE ICDE 2008 and PC Chair of EDBT 2012 Industry and Applications Track. She initiated and has been organizing the workshop series Enabling Real-Time Business Intelligence (BIRTE) in conjunction with VLDB since 2006 and Business Process Intelligence (BPI) in conjunction with BPM (from 2005 until 2010). She currently serves as a member of the Executive Committee of IEEE Technical Committee of Data Engineering. Her interests are information management technologies in general, and in particular, real-time business intelligence, text analytics, and data management platforms.

Title:
Fractional calculus: Fundamentals, computational implementation and applications

Abstract:

Fractional Calculus (FC) started in 1695 when L'Hôpital wrote a letter to Leibniz asking for the meaning of D^ny for n = 1/2. Starting with the ideas of Leibniz many important mathematicians developed the theoretical concepts. Olivier Heaviside applied FC in the electrical engineering, but, the visionary and important contributions were forgotten. Only during the eighties FC emerged associated with phenomena such as fractal and chaos and, consequently, in the modeling of dynamical systems. This lecture introduces the FC fundamental mathematical concepts, and reviews the main computational approaches for implementing fractional operators. In the last years Fractional Calculus (FC) become a 'new' tool for the modeling and control of dynamical systems. Based on the FC mathematical concepts, this lecture presents several applications in the areas of modeling and control, namely fractional PID, fractional electromagnetism, and DNA decoding.

Biography:

Professor J. A. Tenreiro Machado was born in 1957. He graduated with the Engineering (1980), Ph.D. (1989) and Habilitation (1995) degrees in Electrical and Computer Engineering at the University of Porto, Portugal. During 1980-1998 he worked as a Professor at the Department of Electrical and Computer Engineering of the University of Porto. Since 1998 he has been a Coordinator Professor at the Institute of Engineering of the Polytechnic Institute of Porto, Portugal, Department of Electrical Engineering. His primary research areas include robotics, nonlinear dynamics, modeling, control, fractional-order systems, and evolutionary computing. He is co-author of more than 30 articles published in scientific journals. He has had an intense editorial activity, publishing 7 books, editing 15 special issues, mainly in nonlinear dynamics and fractional calculus, serving the editorial board of renowned scientific journals.
