This count, either as a ratio of the total or normalized by dividing by the expected count for a random source model, is known as the index of coincidence, or IC or IOC [2] or IoC [3] for short. Because letters in a natural language are not distributed evenly , the IC is higher for such texts than it would be for uniformly random text strings.
where f t,d is the raw count of a term in a document, i.e., the number of times that term t occurs in document d. Note the denominator is simply the total number of terms in document d (counting each occurrence of the same term separately). There are various other ways to define term frequency: [5]: 128 the raw count itself: tf(t,d) = f t,d
These vectors capture information about the meaning of the word based on the surrounding words. The word2vec algorithm estimates these representations by modeling text in a large corpus. Once trained, such a model can detect synonymous words or suggest additional words for a partial sentence.
Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample. This is an example of a univariate (=single variable) frequency table. The frequency of each response to a survey question is depicted.
Only when the advance knowledge of the content of the message by the receiver is less than 100% certain does the message actually convey information. For example, quoting a character (the Hippy Dippy Weatherman) of comedian George Carlin: Weather forecast for tonight: dark. Continued dark overnight, with widely scattered light by morning. [8]

Jean Smart is nominated for a Golden Globe for 'Hacks.' Here's everything she's shared about her health over the years, including a heart surgery and diabetes.
Another example is the construction of finite fields, which proceeds similarly, starting out with the field of integers modulo some prime number as the coefficient ring R (see modular arithmetic). If R is commutative, then one can associate with every polynomial P in R[x] a polynomial function f with domain and range equal to R.
