Contextually adaptive signal representation using conditional principal component analysis

The conventional method of generating a basis that is optimally adapted (in MSE) for representation of an ensemble of signals is principal component analysis (PCA). A more ambitious modern goal is the construction of bases that are adapted to individual signal instances. Here we develop a new framew...
