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 streams in a more efficient, brain-like way [1,2].
The talk first presents some principles of deep learning implemented in a recently proposed evolving SNN (eSNN) architecture called NeuCube. NeuCube was first proposed for brain data modelling [3,4]. It was further developed as a general purpose SNN development system for the creation and testing of spatio/spectro temporal data machines (STDM) to address challenging data analysis and modelling problems. A version of the NeuCube development system is available free from:  http://www.kedri.aut.ac.nz/neucube/, along with papers and case study data.
The talk introduces a methodology for the design and implementation of SNN systems, called spatio-temporal data machines (STDM) for deep learning and for predictive data modelling of temporal or spatio-/spectro temporal data [5]. A STDM has modules for: preliminary data analysis, data encoding into spike sequences, unsupervised learning of temporal or spatio-temporal patterns, classification, regression, prediction, optimisation, visualisation and knowledge discovery. A STDM can be used to predict early and accurately events and outcomes through 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 data with different characteristics, such as: financial data streams; brain data for brain computer interfaces; personalised and climate date for individual stroke occurrence prediction [6]; ecological and environmental disaster prediction, such as earthquakes. The talk discusses implementation on highly parallel neuromorphic hardware platforms such as the Manchester SpiNNaker [7] and the ETH Zurich chip [8,9]. These STDM 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 and STDM 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].

Plenary Talk 2

Data Mining with Tensor Methods: Introdution and Recent Advance


Dr. Bogusław Cyganek
Associate Professor at AGH University of Science and Technology, Kraków, Poland
Visiting Professor at Wroclaw University of Technology, Wrocław, Poland

Abstract:

One of the goals of data mining is extraction of patterns and knowledge from large amount of data. Frequently, processed data depend on many factors and the well known vector-based classification methods become unsatisfactory since they do not exploit full information contained in data and their structure. Recently developed tensor based methods allow data representation and analysis which directly account for data multidimensionality. Examples can be found in many applications such as face recognition, image synthesis, video analysis, surveillance systems, sensor networks, marketing and medical data analysis, to name a few. This talk will be focused on presentation of the basic ideas, as well as recent achievements, in the domain of data mining with tensor methods. We will present a systematic overview of tensor data representation, tensor decompositions, as well as pattern recognition with single and ensembles of tensor based classifiers. Also practical aspects and implementation issues, related to data processing with tensors, will be presented.
