Automatic Curve Fitting Based on Radial Basis Functions and a Hierarchical Genetic Algorithm

Figure 6

Effect of varying the number of samples on the curve fitting task by using the HGA method. Data and estimates correspond to the best function estimated from the experimental setup with SNR = 3 (solid line estimated function; dashed line real function). From left to right the columns correspond to data sets with 50, 100, and 200 samples, respectively. The rows correspond from top to bottom to the test functions 1 to 5.
