Mining frequent substructures from deforestation objects
TLDR
This paper aims to employ graphs to represent relationships among deforestation objects captured from remote sensing data, and then extract patterns from them applying graph mining, that performs the search for frequent substructures using the FSG graph-based knowledge discovery algorithm. Expand
