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.
In cognitive psychology, Brown–Peterson task (or Brown–Peterson procedure) refers to a cognitive exercise designed to test the limits of working memory duration. The task is named for two notable experiments published in the 1950s in which it was first documented, the first by John Brown [1] and the second by husband-and-wife team Lloyd and Margaret Peterson.
In the television era, scientific demonstrations have featured in science-related entertainment shows such as MythBusters and Brainiac: Science Abuse. Many scientific demonstrations are potentially dangerous, and should not be attempted without considerable laboratory experience and appropriate safety precautions.
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]
In engineering, science, and statistics, replication is the process of repeating a study or experiment under the same or similar conditions. It is a crucial step to test the original claim and confirm or reject the accuracy of results as well as for identifying and correcting the flaws in the original experiment. [1]
The small-world experiment comprised several experiments conducted by Stanley Milgram and other researchers examining the average path length for social networks of people in the United States. [1] The research was groundbreaking in that it suggested that human society is a small-world -type network characterized by short path-lengths.
KATRIN is a German acronym (Karlsruhe Tritium Neutrino Experiment) for an undertaking to measure the mass of the electron antineutrino with sub-eV precision by examining the spectrum of electrons emitted from the beta decay of tritium. The experiment is a recognized CERN experiment (RE14). [1] [2] The core of the apparatus is a 200-ton ...
