Nonrecursive solution for the discrete algebraic Riccati equation and X + A*X -1 A=L

Maria Adam, Nicholas Assimakis (2015)

Open Mathematics

Similarity:

In this paper, we present two new algebraic algorithms for the solution of the discrete algebraic Riccati equation. The first algorithm requires the nonsingularity of the transition matrix and is based on the solution of a standard eigenvalue problem for a new symplectic matrix; the proposed algorithm computes the extreme solutions of the discrete algebraic Riccati equation. The second algorithm solves the Riccati equation without the assumption of the nonsingularity of the transition...

Latent Semantic Indexing for patent documents

Andreea Moldovan, Radu Boţ, Gert Wanka (2005)

International Journal of Applied Mathematics and Computer Science

Similarity:

Since the huge database of patent documents is continuously increasing, the issue of classifying, updating and retrieving patent documents turned into an acute necessity. Therefore, we investigate the efficiency of applying Latent Semantic Indexing, an automatic indexing method of information retrieval, to some classes of patent documents from the United States Patent Classification System. We present some experiments that provide the optimal number of dimensions for the Latent Semantic...
