Research Type Theoretical We present two related contributions of independent interest: (1) high-probability finite sample rates for k-NN density estimation, and (2) practical mode estimators based on k-NN which attain minimax-optimal rates under surprisingly general distributional conditions. The proof of these results are concise applications of Lemma 2 above. They are given in the appendix (long version).
