Intro Iterative <strong>Gaussianization</strong> Experiments ConclusionsExperiment 1: Density estimation toy examplesDensity estimation in high-dimensional problemsUnivariate density estimation is solved:Kernel estimatorsRadial basis function estimatesGaussian mixture modelsWavelet density estimates...High-dimensional density estimation is difficult!Parametric models: e.g. histogram-based→ Many samples needed, curse of dimensionalityNon-parametric models: e.g. Gaussian, GSM, etc.→ knowledge about the PDF
