| Abstract(in English) | A standard approach to evaluating distance between two graphs is to use common subgraphs contained in the two graphs. For practical problem settings including classification, only a part of subgraphs would be important, but adaptively estimating those important subgraphs is computationally infeasible. In this paper, we define graph metric learning as an optimization problem of sparse weight parameters for a set of subgraphs, and build an efficient method for solving it based on graph mining algorithms. We propose a pruning strategy of the search tree of subgraphs based on the ideas of Safe Screening and Working Set Selection. We also propose to combine these methods with a range-based screening, by which the search tree can be reduced further. |
