A remark on Landahl's theory of learning

  • N. Rashevsky


It is pointed out that the equations of Landahl's learning theory may be formally interpreted in terms of a different neural network than that considered originally by Landahl. The suggested interpretation is based on this author's theory of elimination of a wrong act through a delayed conditioned reflex which produces a reaction opposite to the wrong act.
