- Abstract summary: We propose alternate sources of information to use as descriptor for the classification, which we denominate as density time-evolution pattern (D-TEP) and state density time-evolution pattern (SD-TEP)
Our results show a significant improvement compared to previous studies at five synthetic network databases and also seven real world databases.

- Abstract: Network modeling has proven to be an efficient tool for many
interdisciplinary areas, including social, biological, transport, and many
other real world complex systems. In addition, cellular automata (CA) are a
formalism that has been studied in the last decades as a model for exploring
patterns in the dynamic spatio-temporal behavior of these systems based on
local rules. Some studies explore the use of cellular automata to analyze the
dynamic behavior of networks, denominating them as network automata (NA).
Recently, NA proved to be efficient for network classification, since it uses a
time-evolution pattern (TEP) for the feature extraction. However, the TEPs
explored by previous studies are composed of binary values, which does not
represent detailed information on the network analyzed. Therefore, in this
paper, we propose alternate sources of information to use as descriptor for the
classification task, which we denominate as density time-evolution pattern
(D-TEP) and state density time-evolution pattern (SD-TEP). We explore the
density of alive neighbors of each node, which is a continuous value, and
compute feature vectors based on histograms of the TEPs. Our results show a
significant improvement compared to previous studies at five synthetic network
databases and also seven real world databases. Our proposed method demonstrates
not only a good approach for pattern recognition in networks, but also shows
great potential for other kinds of data, such as images.

This paper shows a new method to perform supervised learning on Spiking Neural Networks (SNNs), using Spike Timing Dependent Plasticity (STDP) and homeostasis.
A SNN is trained to recognise one or multiple patterns and performance metrics are extracted to measure the performance of the network.
This method of training an SNN to detect spatial patterns may be applied to pattern recognition in static images or traffic analysis in computer networks.
