Instrumentation and the ready availability of sensors is leading to a dramatic increase in the collection of Data, and the field of Big Data is now much in favour. In effect Big Data refers to the dramatic increase in the amount and rate of data being created and collected, driven by the number and types of acquisition devices and instrumentation.
According to the US National Science Foundation “Big Data are large, diverse, complex, longitudinal, and/or distributed data sets generated from instruments, sensors, Internet transactions, email, video, click streams, and/or all other digital sources available today and in the future’ (Core Techniques and Technologies for Advanced Big Data Science and Engineering, Solicitation 12-499).
Illustration of the sources of Big Data include streaming data from instrumentation sensors, satellite and medical imagery, video from security cameras, as well as data derived from financial markets and operations. Big data sets from these sources can contain gigabytes or terabytes of data.
In test, measurement and control applications, engineers and scientists can collect vast amounts of data in short periods of time. Large gas turbine manufacturers report that data from instrumented electricity generating turbines, while in manufacturing test, generate over 10 terabytes of data per day. As another example, typically, more than 5 billion data points are recorded every 6 months in a plant with about 320 recording sensor measurements every second.
In this context, the Internet of Things (IoT) may well be the most disruptive technological revolution since the advent of the Internet. Projections indicate that up to 100 billion objects will be connected to the Internet by 2020. IoT covers all types of sensors, communication protocols, computational tools, techniques, devices, processors, embedded systems, data warehousing, big data, cloud computing, server farms, grid computing etc.
A key requirement from Big Data is the need to extract relevant information to effect decisions through the use of advanced Signal Processing tools.
In this presentation, first establishing the background to Big Data and its relevance to instrumentation, the talk will touch on Data analytics, and discuss the tools needed for analysing the Data, and in particular address three aspects of advanced signal processing – streaming algorithms for recursive computation; use of graph theory, and finally the use of tensor algebra to develop signal processing techniques for Big Data.
