The Backward Martingale convergence theorem allows to prove a strong law of large 2019-12-05 A famous theorem of De Finetti (1931) shows that an exchangeable sequence of $\{0, 1\}$-valued random variables is a unique mixture of coin tossing processes. Many generalizations of this result have been found; Hewitt and Savage (1955) for example extended De Finetti's theorem to arbitrary compact state spaces (instead of just $\{0, 1\}$). The symmetric states on a quasi local C*–algebra on the infinite set of indices J are those invariant under the action of the group of the permutations moving only a finite, but arbitrary, number of elements of J. The celebrated De Finetti Theorem describes the structure of the symmetric states (i.e. exchangeable probability measures) in classical probability.

4, several de Finetti theorems for different conditions are given. These de Finetti theorems can be independent with the dimension. Even under the infinite dimen-sional case, they still converge. However, These de Finetti theorems are polynomial and not exponential. As the key size goes to infinite, they can not exponentially converge to zero. Whether such polynomial de Finetti theorems can be applied to

In probability theory, de Finetti's theorem explains why exchangeable observations are conditionally independent given some latent variable to which an epistemic probability distribution would then be assigned. It is named in honor of Bruno de Finetti.. It states that an exchangeable sequence of Bernoulli random variables is a "mixture" of independent and identically distributed (i.i.d
