 # Mathematical Background
 
 The Deepsphere package uses the manifold of the sphere to perform the convolutions on the data. Underlying the application of convolutional networks to spherical data through a graph-based discretization lies the field of Graph Signal Processing (GSP). Graph Signal Processing is a field trying to define classical spectral methods on graphs, similarly to the theories existing in the time domain.
