As in any lifting transform we need to define the split, predict and update steps. The split step is defined over the node set by using the parity of t. The even vertex set V
WebIn this work, we extend recent theoretical results on SCs to regular Cell Complexes, topological objects that flexibly subsume SCs and graphs. We show that this generalisation provides a powerful set of graph "lifting" transformations, each leading to a unique hierarchical message passing procedure. WebSep 19, 2024 · In collaboration with colleagues from Cambridge, Oxford, and Max Planck Institute [21–22], we showed the possibility to construct a “lifting transformation” that augments the graph with such higher-order cells, on which one can perform a more complex form of hierarchical message passing.
WebAug 3, 2024 · The lifting structure [SWELDENS1996186, sweldens1998lifting], which factors the wavelet transforms into elementary steps, namely lifting steps, is a general framework to customize wavelets adapted to arbitrary domains (e.g., graphs, manifolds) or data/signals at hand, leading to the so-called second-generation wavelets. Its spatial ... WebComplexes, topological objects that flexibly subsume SCs and graphs.
