The method uses the\nExpectation Propagation (EP) algorithm to approximate the\nposterior distribution of the inverse bandwidth (precision\nmatrix) under a leave-one-out cross-validated likelihood. Three\ncovariance structures are supported: isotropic (scalar\nprecision), diagonal, and full precision matrix. Online\nBayesian updating is supported for the isotropic case. The\napproximate posterior can be used for bandwidth selection,\nmodel comparison (via the model evidence / Bayes factor), and\nonline learning.", "License": "GPL-3", "Encoding": "UTF-8",
