How would you perform accurate classification on a very large dataset, by just looking at a sample of it? One of his recent papers is about big data and similarity metrics. In this work Rocco proposes a deterministic method to obtain subsets from Big Data which are a good representative of the inherent structure in the data itself. This allows one to consider only a subset of the entire dataset, still performing at high accuracy if not better than traditional (eg. As you can see, there is always a solution in Big Data.
