For the resulting quantizing density estimator (QDE) we present a general method for parameter estimation and model selection. We show how projection sets which ...
We suggest a nonparametric framework for unsupervised learning of projection models in terms of density estimation on quantized sample spaces.
Well known approaches include kernel estimators, projection pursuit, tree- structured algorithms such as CART, and \partition-based" density estimators, which.
