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

Figure 7

Effect of varying the signal-to-noise ratio on the curve fitting task by using the HGA method. Data and estimates correspond to the best function estimated from the experimental setup for data sets with 50 samples (solid line estimated function; dashed line real function). From left to right the columns correspond to SNR = 2, 3, and 4, respectively. The rows correspond from top to bottom to the test functions 1 to 5.
