设n,k ∈ N,r > 0,设en,r(Pk)r = inf 1/K <$ki =1 <$Xi- f(Xi)<$r,其中下确界取于所有可测映射f:Rd → Rd,|f(R d)|≤ n且X 1,...,X k是i.i.d. R d值随机变量。我们分析了渐近a.s.第n个经验量化误差e n,r(P k)的行为。
For n,k ∈ N and r > 0 let e n,r (P k ) r = inf 1/K Σ k i=1 ∥X i - f(X i )∥ r , where the infimum is taken over all measurable maps f:R d → R d with |f(R d )| ≤ n and X 1 ,...,X k are i.i.d. R d -valued random variables. We analyse the asymptotic a.s. behaviour of the nth empirical quantization error e n,r (P k ).
