An Adaptive Spline Non-linear Function for Blind Signal Processing
In this paper a new adaptive non linear function for blind signal processing is presented. It is based on a spline approximation whose control points are adaptively changed using information maximization techniques. The monotonously increasing characteristic is obtained using suitable B-spline functions imposing simple constraints on its control points. In particular, the problem of adaptively ...
متن کاملStable local volatility function calibration using spline kernel
We propose an optimization formulation using the l1 norm to ensure accuracy and stability in calibrating a local volatility function for option pricing. Using a regularization parameter, the proposed objective function balances calibration accuracy with model complexity. Motivated by the support vector machine learning, the unknown local volatility function is represented by a spline kernel fun...
متن کاملAutomatic Modelling of Fundamental Frequency Using a Quadratic Spline Function
An algorithm for the automatic coding of fundamental frequency is described using atechnique called asymmetrical modal quadratic regression. The output of the algorithm, asequence of target points , can be used as input for fundamental frequency synthesisby a quadratic spline function.
متن کاملMultilayer feedforward networks with adaptive spline activation function
In this paper, a new adaptive spline activation function neural network (ASNN) is presented. Due to the ASNN's high representation capabilities, networks with a small number of interconnections can be trained to solve both pattern recognition and data processing real-time problems. The main idea is to use a Catmull-Rom cubic spline as the neuron's activation function, which ensures a simple str...
متن کاملSurface Subdivision Schemes Generated by Refinable Bivariate Spline Function Vectors
Abstract The objective of this paper is to introduce a direct approach for generating local averaging rules for both the √ 3 and 1-to-4 vector subdivision schemes for computer-aided design of smooth surfaces. Our innovation is to directly construct refinable bivariate spline function vectors with minimum supports and highest approximation orders on the six-directional mesh, and to compute their...
