Key linkage

  • the data are never sufficient logically to eliminate all completing hypotheses.
  • We can combine our knowledge about the environment, inductive biases and learning to model how children acquire word meanings by construction. This approach is called Rational Constructivism.

Equation or Formula

  • size principle likelihood: $P(d|h)=\frac{1}{|h|}$
