Sparse Oracle Inequalities for Variable Selection via Regularized Quantization

Clément Levrard

We give oracle inequalities on procedures which combines quantization and variable selection via a weighted Lasso $k$ -means type algorithm. The results are derived for a general fa…

Nonasymptotic bounds for vector quantization in Hilbert spaces

Clément Levrard

Recent results in quantization theory show that the mean-squared expected distortion can reach a rate of convergence of $O (1/ n)$ , where $n$ is the sample size [see, e.g.,…
