Jean-Paul Benzécri
Jean-Paul Benzécri was a French mathematician and statistician. He studied at École Normale Supérieure and was professor at Université de Rennes and later for most of his career at the Paris Institute of Statistics (l'Institut de Statistique de l'Université de Paris), Université Pierre-et-Marie-Curie in Paris. He is most known for his specific inductive approach to data analysis which led to the creation of Correspondence analysis, a statistical technique for analyzing contingency tables and for the invention of the nearest-neighbor chain algorithm for agglomerative hierarchical clustering. Early life Jean-Paul Benzécri was born in Oran, Algeria, in 1932, where his father was a doctor. He attended high school in Lycée Lamoricière, Oran and Lycée Bugeaud, Alger. In 1950, he was first in the entrance examination to the ENS (École Normale Supérieure) in Paris and again in 1953 to the "Agrégation de Mathématiques", a national teacher's diploma examination.

Oran
Oran () is a major coastal city located in the northwest of Algeria. It is considered the second most important city of Algeria, after the capital, Algiers, because of its population and commercial, industrial and cultural importance. It is west-southwest from Algiers. The total population of the city was 803,329 in 2008, while the metropolitan area has a population of approximately 1,500,000, making it the second-largest city in Algeria. Etymology The word ''Wahran'' comes from the Berber expression ''wa - iharan'' (place of lions). A locally popular legend tells that in the period around AD 900, there were sightings of Barbary lions in the area. The last two lions were killed on a mountain near Oran, and it became known as ''la montagne des lions'' ("The Mountain of Lions"). Two giant lion statues stand in front of Oran's city hall, symbolizing the city. History Overview During the Roman Empire, a small settlement called ''Unica Colonia'' existed in the area of the current ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contingency Table
In statistics, a contingency table (also known as a cross tabulation or crosstab) is a type of table in a matrix format that displays the multivariate frequency distribution of the variables. They are heavily used in survey research, business intelligence, engineering, and scientific research. They provide a basic picture of the interrelation between two variables and can help find interactions between them. The term ''contingency table'' was first used by Karl Pearson in "On the Theory of Contingency and Its Relation to Association and Normal Correlation", part of the '' Drapers' Company Research Memoirs Biometric Series I'' published in 1904. A crucial problem of multivariate statistics is finding the (direct-)dependence structure underlying the variables contained in high-dimensional contingency tables. If some of the conditional independences are revealed, then even the storage of the data can be done in a smarter way (see Lauritzen (2002)). In order to do this one can use in ...

Cluster Analysis
Cluster analysis or clustering is the data analyzing technique in which task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more Similarity measure, similar (in some specific sense defined by the analyst) to each other than to those in other groups (clusters). It is a main task of exploratory data analysis, and a common technique for statistics, statistical data analysis, used in many fields, including pattern recognition, image analysis, information retrieval, bioinformatics, data compression, computer graphics and machine learning. Cluster analysis refers to a family of algorithms and tasks rather than one specific algorithm. It can be achieved by various algorithms that differ significantly in their understanding of what constitutes a cluster and how to efficiently find them. Popular notions of clusters include groups with small Distance function, distances between cluster members, dense areas of the data space, intervals or pa ...

Zellig Harris
Zellig Sabbettai Harris (; October 23, 1909 – May 22, 1992) was an influential American linguist, mathematical syntactician, and methodologist of science. Originally a Semiticist, he is best known for his work in structural linguistics and discourse analysis and for the discovery of transformational structure in language. These developments from the first 10 years of his career were published within the first 25. His contributions in the subsequent 35 years of his career include transfer grammar, string analysis ( adjunction grammar), elementary sentence-differences (and decomposition lattices), algebraic structures in language, operator grammar, sublanguage grammar, a theory of linguistic information, and a principled account of the nature and origin of language. Biography Harris was born on October 23, 1909, in Balta, in the Podolia Governorate of the Russian Empire (present-day Ukraine). He was Jewish. In 1913 when he was four years old his family immigrated to Philadelph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Guttman
Louis Guttman (; February 10, 1916 – October 25, 1987) was an American sociologist and Professor of Social and Psychological Assessment at the Hebrew University of Jerusalem, known primarily for his work in social statistics. Biography Louis (Eliyahu) Guttman was born in New York City and grew up in the Jewish community of Minneapolis, Minnesota. Guttman received both his BA in 1936 and MA in 1939 at the University of Minnesota, and his PhD in Social and Psychological Measurement in 1942. In 1947 Guttman and his wife Ruth immmigrated to Palestine. Guttman died on October 25, 1987, while on sabbatical in Minneapolis. Academic career From 1941 to 1947 Guttman was professor of sociology at Cornell University, while as part of the World War II effort, he also served as an Expert Consultant to the US Army's Research Branch. He founded and was the scientific director of the Israel Institute of Applied Social Research, later renamed the Guttman Institute before finally becoming the ...

Natural Language Processing
Natural language processing (NLP) is a subfield of computer science and especially artificial intelligence. It is primarily concerned with providing computers with the ability to process data encoded in natural language and is thus closely related to information retrieval, knowledge representation and computational linguistics, a subfield of linguistics. Major tasks in natural language processing are speech recognition, text classification, natural-language understanding, natural language understanding, and natural language generation. History Natural language processing has its roots in the 1950s. Already in 1950, Alan Turing published an article titled "Computing Machinery and Intelligence" which proposed what is now called the Turing test as a criterion of intelligence, though at the time that was not articulated as a problem separate from artificial intelligence. The proposed test includes a task that involves the automated interpretation and generation of natural language ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mathematical Linguistics
Mathematical linguistics is the application of mathematics to model phenomena and solve problems in general linguistics and theoretical linguistics. Mathematical linguistics has a significant amount of overlap with computational linguistics. Discrete Mathematics Discrete mathematics is used in language modeling, including formal grammars, language representation, and historical linguistic trends. Set Theory Semantic classes, word classes, natural classes, and the allophonic variations of each phoneme in a language are all examples of applied set theory. Set theory and concatenation theory are used extensively in phonetics and phonology. Combinatorics In phonotactics, combinatorics is useful for determining which sequences of phonemes are permissible in a given language, and for calculating the total number of possible syllables or words, based on a given set of phonological constraints. Combinatorics on words can reveal patterns within words, morphemes, and sentence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
