WebThe decoding for BICM in the previous subsection is “one-shot” in the sense that the decoder for the binary code is activated only once. The suboptimality of this approach in Section 5.2, especially for natural mapping, comes from the fact that only bit-wise metric is computed without any information on the other labeling bits.BICM with iterative … Webinformation and pointwise mutual information. We then introduce their normal-ized variants (Sect. 3). Finally, we present an empirical study of the e ectiveness of these normalized variants (Sect. 4). 2 Mutual information 2.1 De nitions Mutual information (MI) is a measure of the information overlap between two random variables.

In probability theory and information theory, the mutual information (MI) of two random variables is a measure of the mutual dependence between the two variables. More specifically, it quantifies the "amount of information" (in units such as shannons (bits), nats or hartleys) obtained about one random variable by … See more Let $${\displaystyle (X,Y)}$$ be a pair of random variables with values over the space $${\displaystyle {\mathcal {X}}\times {\mathcal {Y}}}$$. If their joint distribution is $${\displaystyle P_{(X,Y)}}$$ and the marginal … See more Nonnegativity Using Jensen's inequality on the definition of mutual information we can show that $${\displaystyle \operatorname {I} (X;Y)}$$ is non-negative, i.e. $${\displaystyle \operatorname {I} (X;Y)\geq 0}$$ See more In many applications, one wants to maximize mutual information (thus increasing dependencies), which is often equivalent to minimizing conditional entropy. Examples include: • In search engine technology, mutual information … See more Intuitively, mutual information measures the information that $${\displaystyle X}$$ and $${\displaystyle Y}$$ share: It measures how … See more Several variations on mutual information have been proposed to suit various needs.

Mutual information (MI) measures how much two variables are inter-dependent. So, higher the MI, more similar the variables. Two variables could be, for example, the intensity values of two greyscale images. But many algorithms use the matching cost, i.e. how much two variables are different. Hence, the minus sign.
