Description
Many objects of our today life are discrete and described by sequences of elements (strings) or more complex relationships (e.g. graphs). Inferences from these discrete objects is the field of structural pattern recognition. This research field has been limited for decades by costly (e.g. based on subgraph isomorphism) or poorly efficient metrics usually combined with limited machine learning algorithms (mainly k-nearestneighbours algorithm). Two recent breakthroughs have drastically changed this situation: Graph kernels and more recently Graph Neural Networks (GNN). This project aims at solving the current limitations of the two basic operations of GNN, namely graph convolution and graph decimation. We also plan to investigate inferences on a (yet) less investigated type of objects: sequences of graphs.
