On Density Estimation in the View of Kolmogorov's Ideas in Approximation Theory
从柯尔莫哥洛夫逼近理论思想看密度估计
The paper deals with upper and lower bounds for the quality of (probability) density estimation. Connections are established between these problems and the theory of approximation of functions. Particularly, it is demonstrated how some of Kolmogorov's concepts work.
