Figure 5From: Parameter estimation for stiff equations of biosystems using radial basis function networksThe adoption of fitness transformation that facilitates parameter estimation using RBFN. View of the fitness functions when 2 parameters (K i , K j ) are estimated, where the X-axis and Y-axis represent logarithmic coordinates of data and the Z-axis represents fitness of the coordinates. On the right, logarithmic transformation of fitness is applied.Back to article page
