In mathematics — specifically, in large deviations theory — the tilted large deviation principle is a result that allows one to generate a new large deviation principle from an old one by "tilting", i.e. integration against an exponential functional. It can be seen as an alternative formulation of Varadhan's lemma. ==Statement of the theorem== Let ''X'' be a Polish space (i.e., a separable, completely metrizable topological space), and let (''μ''''ε'')''ε''>0 be a family of probability measures on ''X'' that satisfies the large deviation principle with rate function ''I'' : ''X'' → (). Let ''F'' : ''X'' → R be a continuous function that is bounded from above. For each Borel set ''S'' ⊆ ''X'', let : and define a new family of probability measures (''ν''''ε'')''ε''>0 on ''X'' by : Then (''ν''''ε'')''ε''>0 satisfies the large deviation principle on ''X'' with rate function ''I''''F'' : ''X'' → () given by : 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Tilted large deviation principle」の詳細全文を読む スポンサード リンク
