@ARTICLE{10.21494/ISTE.OP.2017.0179, TITLE={Sleep Paintings by Artificial Ants}, AUTHOR={Carlos M. Fernandes, }, JOURNAL={Art and Science}, VOLUME={1}, NUMBER={Issue 1}, YEAR={2017}, URL={http://www.openscience.fr/Sleep-Paintings-by-Artificial-Ants}, DOI={10.21494/ISTE.OP.2017.0179}, ISSN={2515-8767}, ABSTRACT={This paper provides technical and conceptual information on a swarm art project called Sleep Paintings. The project consists of a series of colour images generated by an ant-based clustering algorithm operating with sleep data sets extracted from electroencephalogram (EEG) signals. The algorithm was originally proposed for clustering and classification and is described by a simple set of equations that model the local behavior of artificial ants (data samples) in a way that, when travelling on a heterogeneous 2-dimensional lattice of vectors, they form clusters of similar data samples, while changing the vectors of the environmental lattice. The 2-dimensional colored abstract sketches of human sleep described in the paper result from the visualization of the lattice.}}
