In the field of machine learning, the goal of statistical classification is to use an object's characteristics to identify which class (or group) it belongs to.
 A linear classifier achieves this by making a classification decision based on the value of a linear combination of the characteristics.
 An object's characteristics are also known as feature values and are typically presented to the machine in a vector called a feature vector.
 Such classifiers work well for practical problems such as document classification, and more generally for problems with many variables (features), reaching accuracy levels comparable to non-linear classifiers while taking less time to train and use.
Vector was a rock band formed in Sacramento, California in the early 1980s by Jimmy Abegg, Steve Griffith and Charlie Peacock.
 The band had several drummers over the years, including Aaron Smith and Bruce Spencer, both of whom also played drums for The 77s.
The 1989 Panamanian coup d'état attempt was a failed coup d'état which occurred in Panama City on 3 October.
 The attempt was led by Major Moisés Giroldi, supported by a group of officers who had returned from a United Nations peacekeeping mission in Namibia.
 Although the plotters succeeded in capturing Panamanian dictator Manuel Noriega, the coup was quickly suppressed.
 Giroldi, together with nine other members of the Panamanian Defense Forces, was executed on 3 and 4 October 1989.
 An eleventh participant died in prison after being tortured.
 These events became known as the "Albrook massacre".
On September 7, 1977, Carter and Torrijos met in Washington to sign the treaties in a ceremony that also was attended by representatives of twenty-six other nations of the Western Hemisphere.
 The Panama Canal Treaty, the major document signed on September 7, abrogated the 1903 treaty and all other previous bilateral agreements concerning the canal.
 The treaty was to enter into force six months after the exchange of instruments of ratification and to expire at noon on December 31, 1999.
 The Panama Canal Company and the Canal Zone government would cease to operate and Panama would assume complete legal jurisdiction over the former Canal Zone immediately, although the United States would retain jurisdiction over its citizens during a thirty-month transition period.
 Panama would grant the United States rights to operate, maintain, and manage the canal through a new United States government agency, the Panama Canal Commission.
 The commission would be supervised by a board of five members from the United States and four from Panama; the ratio was fixed for the duration of the treaty.
 The commission would have a United States administrator and Panamanian deputy administrator until January 1, 1990, when the nationalities of these two positions would be reversed.
 Panamanian nationals would constitute a growing number of commission employees in preparation for their assumption of full responsibility in 2000.
 Another binational body, the Panama Canal Consultative Committee, was created to advise the respective governments on policy matters affecting the canal's operation.
El Tamborito, literally translated to “the Little Drum”, is a genre of Panamanian folkloric music and dance dating back as early as the 17th century.
 The Tamborito is the national song and dance of Panama.
 The dance is a romantic, couple’s dance, often involving a small percussion ensemble, and in all versions; a female chorus.
 The Tamborito is performed in formal costumes in front of large, interactive crowds that form a large circle around the performers.
 The members of such crowds often participate in the percussion of the song as well as the actual dance itself.
 The Tamborito is most commonly performed during Panamanian festivals, and in particular, the Panama Carnival.
The Newman–Penrose (NP) formalism is a set of notation developed by Ezra T. Newman and Roger Penrose for general relativity (GR).
 Their notation is an effort to treat general relativity in terms of spinor notation, which introduces complex forms of the usual variables used in GR.
 The NP formalism is itself a special case of the tetrad formalism, where the tensors of the theory are projected onto a complete vector basis at each point in spacetime.
 Usually this vector basis is chosen to reflect some symmetry of the space-time, leading to simplified expressions for physical observables.
 In the case of the NP formalism, the vector basis chosen is a null tetrad: a set of four null vectors—two real, and a complex-conjugate pair.
 The two real members asymptotically point radially inward and radially outward, and the formalism is well adapted to treatment of the propagation of radiation in curved spacetime.
 The most often-used variables in the formalism are the Weyl scalars, derived from the Weyl tensor.
 In particular, it can be shown that one of these scalars--formula_1 in the appropriate frame—encodes the outgoing gravitational radiation of an asymptotically flat system.
In machine learning, kernel methods are a class of algorithms for pattern analysis, whose best known member is the support vector machine (SVM).
 The general task of pattern analysis is to find and study general types of relations (for example clusters, rankings, principal components, correlations, classifications) in datasets.
 For many algorithms that solve these tasks, the data in raw representation have to be explicitly transformed into feature vector representations via a user-specified "feature map": in contrast, kernel methods require only a user-specified "kernel", i.e., a similarity function over pairs of data points in raw representation.
Roberto Emilio Arias (1918–1989), known as "Tito", was a Panamanian international lawyer, diplomat and journalist who was the husband of ballerina Dame Margot Fonteyn.
 Arias was from a prominent Panamanian political family, whose members had reached the Presidency four times; amongst them his father Harmodio Arias.
The Advanced Scientific Computer (ASC) is a supercomputer designed and manufactured by Texas Instruments (TI) between 1966 and 1973.
 The ASC's central processing unit (CPU) supported vector processing, a performance-enhancing technique which was key to its high-performance.
 The ASC, along with the Control Data Corporation STAR-100 supercomputer (which was introduced in the same year), were the first computers to feature vector processing.
 However, this technique's potential was not fully realized by either the ASC or STAR-100 due to an insufficient understanding of the technique; it was the Cray Research Cray-1 supercomputer, announced in 1975 that would fully realize and popularize vector processing.
 The more successful implementation of vector processing in the Cray-1 would demarcate the ASC (and STAR-100) as first-generation vector processors, with the Cray-1 belonging in the second.
Cage9 is a Panamanian/American alternative rock band, formed in Panama City in 1993.
 The group was founded by Evan Rodaniche (guitar/vocals) and is currently based out of Los Angeles, California.
