On Directed Information and Gambling

Haim H. Permuter, Young-Han Kim, Tsachy Weissman

摘要:

我们研究的问题,赌博在赛马与因果边信息,并表明,梅西的有向信息的特点是增加的最大可实现的资本增长率由于边信息的可用性。该结果给出了定向信息$I(Y^n \to X^n)$作为$Y^n$ \emph{causally}提供的关于$X^n$的信息量的自然解释。扩展到股票市场的投资组合策略和数据压缩与因果边信息进行了讨论。

英文摘要:

We study the problem of gambling in horse races with causal side information and show that Massey's directed information characterizes the increment in the maximum achievable capital growth rate due to the availability of side information. This result gives a natural interpretation of directed information $I(Y^n \to X^n)$ as the amount of information that $Y^n$ \emph{causally} provides about $X^n$. Extensions to stock market portfolio strategies and data compression with causal side information are also discussed.
