In this paper, we deal with the construction of lower-dimensional manifolds from high-dimensional data which is an important task in data mining, machine learning and statistics. Here, we consider principal manifolds as the minimum of a regularized, non-linear empirical quantization error functional. For the discretization we use a sparse grid method in(More)
The key–value system is justly popular as it greatly simplifies controlling packages for the user. Unfortunately , that ease of use is not transferred into setting up key–value systems for authors of prepackaged T E X code. This article describes how to implement key–value controls for both T E X and L A T E X authors, including a brief overview of how the(More)
