On a class of weak Tchebycheff systems
In this paper we study the approximation power, the existence of a normalized B-basis and the structure of a degree-raising process for spaces of the form span < 1, x, . . . , x, u(x), v(x) >, requiring suitable assumptions on the functions u and v. The results about degree raising are detailed for special spaces of this form which have been recently introduced in the area of CAGD.
متن کاملBest Bases for Classiication
Feature extraction is important in pattern recognition. Wavelet packet has been recently used in choosing the best bases for feature extraction in classiication, combining the feature extraction and feature selection processes into one. This paper proposed a new criterion for best bases selection for classiication. In contrast with the previous work in this area, the new criterion is more robus...
متن کاملBest bases for signal spaces
Article history: Received 2 October 2016 Accepted 3 October 2016 Available online xxxx Presented by Haïm Brézis We discuss the topic of selecting optimal orthonormal bases for representing classes of signals defined either through statistics or via some deterministic characterizations, or combinations of the two. In all cases, the best bases result from spectral analysis of a Hermitian matrix t...

متن کاملOn the Statistics of Best Bases Criteria ?
Wavelet packets are a useful extension of wavelets providing an adaptive timescale analysis. In using noisy observations of a signal of interest, the criteria for best bases representation are random variables. The search may thus be very sensitive to noise. In this paper, we characterize the asymptotic statistics of the criteria to gain insight which can in turn, be used to improve on the perf...
