Note on universal algorithms for learning theory
We study the universal estimator for the regression problem in learning theory considered by Binev et al. This new approach allows us to improve their results.

Uniform approximation theorems for real-valued continuous functions.
For a completely regular space X, C(X) and C*(X) denote, respectively, the algebra of all real-valued continuous functions and bounded real-valued continuous functions over X. When X is not a pseudocompact space, i.e., if C*(X) ≠ C(X), theorems about uniform density for subsets of C*(X) are not directly translatable to C(X). In [1], Anderson gives a sufficient condition in order for certain rings of C(X) to be uniformly dense, but this condition is not necessary.In this paper we study the uniform...
