LETTER Communicated by Alexander Loskutov Hebbian Self-Organizing Integrate-and-Fire Networks for Data Clustering

We propose a Hebbian learning-based data clustering algorithm using spiking neurons. The algorithm is capable of distinguishing between clusters and noisy background data and finds an arbitrary number of clusters of arbitrary shape. These properties render the approach par-ticularly useful for visual scene segmentation into arbitrarily shaped homogeneous regions. We present several application examples, and in order to highlight the advantages and the weaknesses of our method, we systematically compare the results with those from standard methods such as the k-means and Ward’s linkage clustering. The analysis demon-strates that not only the clustering ability of the proposed algorithm is more powerful than those of the two concurrent methods, the time com-plexity of the method is also more modest than that of its generally used strongest competitor.
