We leave this exact calculation as exercise 12. We see in Section 3.8 that perplexity is also closely related to the information- theoretic notion of entropy.

How do you concatenate two languages?
The union of two languages L and M, denoted L ? M, is the set of strings that are in either L, or M, or both. The concatenation of languages L and M, denoted L.M or just LM , is the set of strings that can be formed by taking any string in L and concatenating it with any string in M.What is an example of language concatenation?
Let L1 and L2 be languages. Then the concatenation of L1 with L2 is denoted as L1L2 and it is defined as L1L2 = { uv u L1 and v L2 }. That is L1L2 is the set of strings obtained by concatenating strings of L1 with those of L2. For example {ab, b} {aaa, abb, aaba} = {abaaa, ababb, abaaba, baaa, babb, baaba}.What is ???
The set of all strings over an alphabet ? is denoted ??. (In language theory, the symbol ? is typically used to denote "zero or more", so ?? is the set of strings made up of zero or more symbols from \\Sigma.)- To find the language it accepts, first from the initial state go to state 1 by reading one a. Then from state 1 go through the cycle 1 - 2 - 1 any number of times by reading substring ab any number of times to come back to state 1. This is represented by (ab)*.
