Weighted Least Squares

This function implements a method of using genetic algorithms to optimise the form of a polynomial, i.e. reducing the number of terms required in comparison to a least-squares fit using all possible terms, as described in the following paper:Clegg, J. et al, "The use of a genetic algorithm to...

Genetic Programming (GP) generates nonlinear input-output models of dynamical systems from input-output measurement data. This GP-OLS toolbox applies Orthogonal Least Squares algorithm (OLS) to improve the search effeciency of GP.It can be used for static equation discovery or structure... Platforms: Matlab

Place tiles on the board to try to create squares. If the tile touches another tile, the sides that touch must have the same symbols. When you create a square of four tiles, you receive bonus points. Needs The Lobby from www.tams11.com in order to play against other players. Platforms: Windows

This widget makes it possible for you to display 125x125 ad squares ( or some other configurable size ) into a widget-ready bar for WordPressdlT«. You can have just 2 squares, or as many as 8 running together. It also supports multi-widget options. So technically you could have even more than... Platforms: PHP

The Kalman filter can be interpreted as a feedback approach to minimize the least equare error. It can be applied to solve a nonlinear least square optimization problem. This function provides a way using the unscented Kalman filter to solve nonlinear least square optimization problems. Three... Platforms: Matlab

ICP - Iterative Closest Point algorithm, c++ implementation. Handles only points in R^3. Makes use of a kd-tree for closest-point search. ICP finds the transformation of points in data to fit points in model. Fit with respect to minimize a weighted sum of squares for distances between the data... Platforms: Matlab
