Feature selection
Feature selection is the process of selecting a subset of relevant features (variables, predictors) for use in model construction. Stylometry and DNA microarray analysis are two cases where feature selection is used. It should be distinguished from feature extraction. Feature selection techniques are used for several reasons: simplification of models to make them easier to interpret by researchers/users, shorter training times, to avoid the curse of dimensionality, improve data's compatibility with a learning model class, encode inherent symmetries present in the input space.
Bayesian information criterion
In statistics, the Bayesian information criterion (BIC) or Schwarz information criterion (also SIC, SBC, SBIC) is a criterion for model selection among a finite set of models; models with lower BIC are generally preferred. It is based, in part, on the likelihood function and it is closely related to the Akaike information criterion (AIC). When fitting models, it is possible to increase the maximum likelihood by adding parameters, but doing so may result in overfitting.
Northeast Caucasian languages
The Northeast Caucasian languages, also called East Caucasian, Nakh-Daghestani or Vainakh-Daghestani, or sometimes Caspian languages (from the Caspian Sea, in contrast to Pontic languages for the Northwest Caucasian languages), is a family of languages spoken in the Russian republics of Dagestan, Chechnya and Ingushetia and in Northern Azerbaijan as well as in diaspora populations in Western Europe and the Middle East. They are occasionally called Caspian, as opposed to Pontic for the Northwest Caucasian languages.
Grammatical gender
In linguistics, a grammatical gender system is a specific form of a noun class system, where nouns are assigned to gender categories that are often not related to the real-world qualities of the entities denoted by those nouns. In languages with grammatical gender, most or all nouns inherently carry one value of the called gender; the values present in a given language (of which there are usually two or three) are called the genders of that language.
Baltic languages
The Baltic languages are a branch of the Indo-European language family spoken natively or as a second language by a population of about 6.5–7.0 million people mainly in areas extending east and southeast of the Baltic Sea in Europe. Together with the Slavic languages, they form the Balto-Slavic branch of the Indo-European family. Scholars usually regard them as a single subgroup divided into two branches: Western Baltic (containing only extinct languages) and Eastern Baltic (containing at least two living languages, Lithuanian, Latvian, and by some counts including Latgalian and Samogitian as separate languages rather than dialects of those two).
Dyslexia
Dyslexia, previously known as word blindness, is a learning disability that affects either reading or writing. Different people are affected to different degrees. Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing words when reading aloud and understanding what one reads. Often these difficulties are first noticed at school. The difficulties are involuntary, and people with this disorder have a normal desire to learn.
Statistical inference
Statistical inference is the process of using data analysis to infer properties of an underlying distribution of probability. Inferential statistical analysis infers properties of a population, for example by testing hypotheses and deriving estimates. It is assumed that the observed data set is sampled from a larger population. Inferential statistics can be contrasted with descriptive statistics. Descriptive statistics is solely concerned with properties of the observed data, and it does not rest on the assumption that the data come from a larger population.
Sumerian language
Sumerian (Cuneiform: "native tongue") is the language of ancient Sumer. It is one of the oldest attested languages, dating back to at least 2900 BC. It is accepted to be a local language isolate and to have been spoken in ancient Mesopotamia, in the area that is modern-day Iraq. Akkadian, a Semitic language, gradually replaced Sumerian as a spoken language in the area 2000 BC (the exact date is debated), but Sumerian continued to be used as a sacred, ceremonial, literary and scientific language in Akkadian-speaking Mesopotamian states such as Assyria and Babylonia until the 1st century AD.
Fisher information
In mathematical statistics, the Fisher information (sometimes simply called information) is a way of measuring the amount of information that an observable random variable X carries about an unknown parameter θ of a distribution that models X. Formally, it is the variance of the score, or the expected value of the observed information. The role of the Fisher information in the asymptotic theory of maximum-likelihood estimation was emphasized by the statistician Ronald Fisher (following some initial results by Francis Ysidro Edgeworth).
International Phonetic Alphabet
The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of speech sounds in written form. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech–language pathologists, singers, actors, constructed language creators, and translators.
