This paper provides insights into the practical applications of adaptive algorithms with optimum step sizes derived from Taylor Series expansion. Previously, this technique has been adopted for several applications, including adaptive filtering and Independent Component Analysis (ICA). In addition, it is applicable in an extremely broad range of optimization problems. To achieve satisfying performance using this method, the proper set up for relevant algorithm parameters is crucial. Here we address three important issues, i.e., the shifting of data block between iterations, the approximation error due to the truncation of Taylor Series, and the use of prior knowledge of signal statistics. To facilitate presentation, two example algorithms are discussed, namely, the Optimum Block Adaptation with Individual adaptation parameters (OBAI) and Optimum Block Adaptation ICA (OBA-ICA).

The paper is developed in two parts where we discuss a new approach to self-organization in a single-layer linear feed-forward network. First, two novel algorithms for self-organization are derived from a two-layer linear hetero-associative network performing a one-of-m classification, and trained with the constrained least-mean-squared classification error criterion. Second, two adaptive algorithms are derived from these self-organizing procedures to compute the principal generalized eigenvectors of two correlation matrices from two sequences of random vectors. These novel adaptive algorithms can be implemented in a single-layer linear feed-forward network. We give a rigorous convergence analysis of the adaptive algorithms by using stochastic approximation theory. As an example, we consider a problem of online signal detection in digital mobile communications.

A new approach is introduced for formulating the near-field to far-field transformation of the scattered field. The scattered field is expanded as a series of summation in terms of modal wave functions. For the transformation of the scattered field the expansion coefficients should be determined. In this work, we applied the adaptive solution algorithms for extracting unknown expansion coefficients, because of the application simplicity, noise exemption and computational efficiency. These unknown coefficients can be found by the minimization of the adaptive algorithm error using the limited limited number of measurement points around the object. Then, the scattered fields at the desired points can be calculated by using these determined coefficients. We choose the least-mean-square adaptation (LMS) algorithm and apply it to the scattered fields of different objects for noisy and noise free cases. We obtained that the adaptive algorithm transforms the scattered field with more accuracy and less computation time the harmonic expansion technique.
