+<longdescription>
+  Locally Weighted Projection Regression (LWPR) is a recent algorithm
+  that achieves nonlinear function approximation in high dimensional spaces
+  with redundant and irrelevant input dimensions. At its core, it uses
+  locally linear models, spanned by a small number of univariate regressions in
+  selected directions in input space. A locally weighted variant of
+  Partial Least Squares (PLS) is employed for doing the dimensionality
+  reduction.
