This paper introduces SigMaNet, a generalized Graph Convolutional Network (GCN) capable of handling both undirected and directed graphs with weights not restricted in sign nor magnitude. The cornerstone SigMaNet is the Sign-Magnetic Laplacian (LSM), new matrix that we introduce ex novo this work. LSM allows us to bridge gap current literature by extending theory spectral GCNs (directed) positiv...

Context. Open clusters are ideal laboratories to investigate a variety of astrophysical topics, from the properties Galactic disc stellar evolution models. For this purpose, we need know their chemical composition in detail. Unfortunately, number systems with abundances determined high resolution spectroscopy remains small. Aims. Our aim is increase open radial velocities and by sampling few st...
