Generalization:

  • Long-term issue on generalization of evolved programs.
  • The median problem
  • High potential for overfitting
  • Significance of “validation” data
  • Potential resonance with Kalman filtering? Where Kalman filters can help converge on a global optimum even though only subsets of the data are seen at a time.
  • The question of parsimony
  • Simplification as a post-processing step. (Another interesting potential resonance with Wavelet Shrinkage)
