In probability theory, de Finetti's theorem states that exchangeable observations are conditionally independent relative to some latent variable. An epistemic probability distribution could then be assigned to this variable. It is named in honor of Bruno de Finetti. For the special case of an exchangeable sequence of Bernoulli random variables it states that such a sequence is a "mixture" of sequences of independent and identically distributed (i.i.d.) Bernoull… WebAug 20, 2002 · We present an elementary proof of the quantum de Finetti representation theorem, a quantum analog of de Finetti’s classical theorem on exchangeable …
Unknown quantum states: The quantum de Finetti representation
WebBoolean de Finetti Theorem Remark There is no pair of Boolean independent random variables in probability spaces with faithful states. Therefore, in our framework, we just require the GNS representation associated with the state to be faithful. Tail algebra The tail algebra Tof (x i) i2N is de ned by the following formula: T= \1 n=1 Wfx kjk ng ... WebJan 5, 2013 · To remind you where we left off, we had three definitions of probabilities. One, based on the principle of indifference, didn't bring us very far. The second, based on frequentism, was also limited. Subjective probabilities, by contrast, seemed very general and very flexible. But they are so general and so flexible that one might wonder if they ... checkered pattern tile

WebDe Finetti's now by far best known work concerns the notion of exchangeability and the representation theorem. Since the publication in 1964 of the English translation of his 1935 French lectures, La Pr?vision, the result and its philosophy have been standard themes in foundations of probability. Below we shall address the historical and WebAug 1, 2024 · De Finetti’s theorem characterizes all {0, 1}-valued exchangeable sequences as a ‘mixture’ of sequences of independent random variables.
