An Information-Theoretic Proof of a Finite de Finetti Theorem

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 Web2 days ago · A Third Information-Theoretic Approach to Finite de Finetti Theorems. Mario Berta, Lampros Gavalakis, Ioannis Kontoyiannis.
