Ignorance prior

An ignorance prior is a a prior probability function on some problem of interest, usually with the intended properties of being simple to describe and facilitating good learning from the evidence. A classic example would be the inductive prior for Laplace’s Rule of Succession.

Children:

  • Inductive prior

    Some states of pre-observation belief can learn quickly; others never learn anything. An “inductive prior” is of the former type.

Parents:

  • Bayesian reasoning

    A probability-theory-based view of the world; a coherent way of changing probabilistic beliefs based on evidence.
