Abstract : This report is devoted to derivatives estimations. Contrary to the Tikhonov's regularization procedure, we use a recent algebraic framework which involves finally a projection into the Jacobi polynomial basis so as to estimate these derivatives from noisy data. No information about the statistical properties of the noise is required. We give some results concerning the choice of the parameters of this method so as to minimize the noise error contribution and the approximation errors. Moreover, two new central estimators based on such algebraic differentiation techniques are introduced. A comparison is done between these estimations and some of the improved classical numerical differentiation schemes.
