Professor Nikola Kasabov, Auckland University of Technology will be giving a talk on “Deep Learning, Spiking Neural Networks and Spatio-Temporal Data Machines” on Friday 2 September 2016 at Robert Gordon University
The current development of the third generation of artificial neural networks – the spiking neural networks (SNN) along with the technological development of highly parallel neuromorphic hardware systems of millions of artificial spiking neurons as processing elements, makes it possible to model complex data in a more efficient, brain-like way [1,2].
The talk presents some principles of SNN and of deep learning in SNN. It introduces a recently proposed evolving SNN architecture called NeuCube. NeuCube is a non von Neumann, neuromorphic computational architecture, first proposed for brain data modelling [3,4]. It was further developed as a general purpose SNN spatio-temporal data machine and a development system for the creation and testing of temporal or spatio/spectro temporal data applications [5,11]. A version of the NeuCube development system is available from: http://www.kedri.aut.ac.nz/neucube/, along with papers and case study data.
Then the talk introduces also a methodology for the design and implementation of SNN application systems for deep learning, pattern recognition and predictive data modelling on temporal or spatio-/spectro temporal data [5,11]. Such systems have modules for: preliminary data analysis, data encoding into spike sequences, unsupervised learning of temporal or spatio-temporal patterns, classifica tion, regression, prediction, optimisation, visualisation and knowledge discovery. Early and accurate event prediction can be achieved due to the ability of SNN to be trained to spike early, when only a part of a new pattern is presented as input data.
The methodology is illustrated on benchmark problems and data with different characteristics and applications: brain data modelling in neuroinformatics; personalised modelling and event prediction in bioinformatics and neuroinformatics; stroke prediction; brain-computer interfaces; multisensory data analysis and pattern recognition in a real time, such as gas pollution sensors and seismic sensors. The talk discusses implementation of NeuCube based systems on highly parallel neuromorphic hardware platforms [7, 8,9] and the IBM True North. Such systems are not only significantly more accurate and faster than traditional machine learning methods and systems, but they lead to a significantly better understanding of the data and the processes that generated it. New directions for the development of SNN systems are pointed towards a further integration of principles from the science areas of computational intelligence, bioinformatics and neuroinformatics and new applications across domain areas [10,11].
