This paper presents a numerical comparison between algorithms for unconstrained optimization that take account of sparsity in the second derivative matrix of the objective function. Some of the ...

General aspects of polynomial interpolation theory. Formulations in different basis, e.g. Lagrange, Newton etc. and their approximation and computational properties ...

An IML numeric element can have a special value called a missing value that indicates that the value is unknown or unspecified. (A matrix with missing values should not be confused with an empty or ...

A topic that's often very confusing for beginners when using neural networks is data normalization and encoding. Because neural networks work internally with numeric data, binary data (such as sex, ...

With SAS/IML software, a numeric element can have a special value called a missing value that indicates that the value is unknown or unspecified. Such missing values are coded, for logical comparison ...
