In this work, we address this problem by defining a data-driven model upon a family of linear operators (variants of the mesh Laplacian), whose spectra capture global and local geometric properties of the shape at hand.

This augmentation provides an effective workaround for the resolution limitations imposed by the adopted morphable model.

We propose a filtering feature selection framework that considers subsets of features as paths in a graph, where a node is a feature and an edge indicates pairwise (customizable) relations among features, dealing with relevance and redundancy principles.

This problem statement is similar to that of "biclustering", implying that RBC can be cast as a biclustering problem.

An appealing characteristic of the approach is that it aims to discover an abstraction behind low-level sensory data, that is, relevancy.

Score functions induced by generative models extract fixed-dimension feature vectors from different-length data observations by subsuming the process of data generation, projecting them in highly informative spaces called score spaces.
