Distributed mining of molecular fragments

By Giuseppe Di Fatta and Michael R. Berthold


In real world applications sequential algorithms of\ud data mining and data exploration are often unsuitable for\ud datasets with enormous size, high-dimensionality and complex\ud data structure. Grid computing promises unprecedented\ud opportunities for unlimited computing and storage resources. In this context there is the necessity to develop\ud high performance distributed data mining algorithms.\ud However, the computational complexity of the problem and\ud the large amount of data to be explored often make the design of large scale applications particularly challenging. In this paper we present the first distributed formulation of a frequent subgraph mining algorithm for discriminative fragments of molecular compounds. Two distributed approaches have been developed and compared on the well known National Cancer Institute’s HIV-screening dataset. We present experimental results on a small-scale computing environment
