Nowadays, and motivated by the recent advances in information technologies and in the massive use of electronic devices, the amount of generated data has increased at a very high rate. In order to be able to handle these large amounts of data, data mining algorithms are used. This work is focused in the use of clustering and, namely, in the SNN (Shared Nearest Neighbour) algorithm, a density-based clustering algorithm. Clustering algorithms usually present high runtimes due to the quadratic complexity. In this work, the SNN algorithm is used to analyse spatial data. Read More …
