Rissanen: modeling by shortest data description

What changed

Formulated model selection by minimizing the description length of observed data under a model, jointly addressing discrete model structure and real-valued parameter estimation.

Scientific scope

The record is the exact 1978 Automatica paper. Kolmogorov complexity, Solomonoff induction, later stochastic-complexity formulations, normalized maximum likelihood and MDL applications remain separate.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1978 Automatica paper.
