Trigrams are a special case of the n-gram, where n is 3. They are often used in natural language processing for performing statistical analysis of texts and in cryptography for control and use of ciphers and codes .
Using trigrams for accelerating searches is a technique used in some systems for code searching, in situations in which queries that are regular expressions may be useful, [5] [2] [7] in search engines such as Elasticsearch, [8] as well as in databases such as PostgreSQL.
The California Job Case was a compartmentalized box for printing in the 19th century, sizes corresponding to the commonality of letters. The frequency of letters in text has been studied for use in cryptanalysis, and frequency analysis in particular, dating back to the Arab mathematician al-Kindi (c. AD 801–873 ), who formally developed the method (the ciphers breakable by this technique go ...
Weak ciphers do not sufficiently mask the distribution, and this might be exploited by a cryptanalyst to read the message. In cryptanalysis, frequency analysis (also known as counting letters) is the study of the frequency of letters or groups of letters in a ciphertext. The method is used as an aid to breaking classical ciphers.
The bagua (Chinese: 八卦; pinyin: bāguà; lit. 'eight trigrams') is a set of symbols from China intended to illustrate the nature of reality as being composed of mutually opposing forces reinforcing one another. Bagua is a group of trigrams—composed of three lines, each either "broken" or "unbroken", which represent yin and yang ...
The CFPB alleges that Experian "does not take sufficient steps to intake, process, investigate, and notify consumers about consumer disputes, resulting in the inclusion of incorrect information on ...
Scientists were expecting the octopus to work on problem-solving solutions by understanding how the screw top lid works and opening it with its arms. But the octopus bypassed the screw top completely.
n-grams find use in several areas of computer science, computational linguistics, and applied mathematics. They have been used to: design kernels that allow machine learning algorithms such as support vector machines to learn from string data [citation needed] find likely candidates for the correct spelling of a misspelled word [14]
