Probability distributions consistent with a mixed state
For a fixed density matrix it is natural to ask what class of ensembles $pi ,uc i&% gives rise to that density matrix? This problem was addressed by Schrödinger @3#, whose results have been extended by Jaynes @4#, and by Hughston, Jozsa, and Wootters @5#. The result of these investigations, the classification theorem for ensembles, has been of considerable utility in quantum statistical mechani...

متن کاملState-Dependent Probability Distributions in Non Linear Rational Expectations Models∗
In this paper, we solve a large class of non-linear rational expectations models with regime switching, i.e. recurring shifts in parameters. The regime-switches and the shocks may follow state-dependent probability distributions. First, we provide sufficient conditions for the existence of a unique stable equilibrium using a perturbation approach. Then, we provide Taylor expansions of the solut...
متن کاملLearning probability distributions generated by finite-state machines
We review methods for inference of probability distributions generated by probabilistic automata and related models for sequence generation. We focus on methods that can be proved to learn in the inference in the limit and PAC formal models. The methods we review are state merging and state splitting methods for probabilistic deterministic automata and the recently developed spectral method for...
متن کاملUniversally consistent predictive distributions
This paper describes simple universally consistent procedures of probability forecasting that satisfy a natural property of small-sample validity, under the assumption that the observations are produced independently in the IID fashion. The version of this paper at http://alrw.net (Working Paper 18, first posted on 17 April 2017) is updated most often.
