Subobject classifier: In category theory, a subobject classifier is a special object Ω of a category; intuitively, the subobjects of an object "X" correspond to the morphisms from "X" to Ω.  As the name suggests, what a subobject classifier does is to identify/classify subobjects of a given object according to which elements belong to the subobject in question.  Because of this role, the subobject classifier is also referred to as the "truth value object".  In fact, the way in which the subobject classifier classifies subobjects of a given object is by assigning the values true to elements belonging to the subobject in question, and false to elements not belonging to the subobject.  This is why the subobject classifier is widely used in the categorical description of logic.

List of German wine regions: German wine regions are classified according to the quality category that the wine falls into - "Tafelwein, Landwein, Qualitätswein bestimmter Anbaugebiete" (QbA) and "Prädikatswein".  The wine regions allowed to produce QbA and Prädikatswein are further subdivided into four categories, in descending order of size - "Anbaugebiet" (a major wine region), "Bereich" (a district within the wine region), "Großlage" (a collection of vineyards within a district) and "Einzellage" (a single vineyard).  A small number "Einzellagen" do not belong to a "Großlage" and are called "großlagenfrei", but all belong to a Bereich and Anbaugebiet.

Isomorphism-closed subcategory: In category theory, a branch of mathematics, a subcategory formula_1 of a category formula_2 is said to be isomorphism closed or replete if every formula_2-isomorphism formula_4 with formula_5 belongs to formula_6 This implies that both formula_7 and formula_8 belong to formula_1 as well.

Sandalpur: Sandalpur is a village in the Araria district in Bihar.  The two primary religions in Sandalpur are Muslim and Hindu.  Muslims belong to Shershahwadi cast, this cast is in OBC category.  Hindus belong to Rajput and Harijon.  Villagers are farmers.

Economically Backward Class: The extremely poor people having annual income less than Rs.1.00 lakh and who do not belong to any social category such as SC/ST/OBC, have been categorized as Economically Backward Classes (EBCs).

Support vector machine: In machine learning, support vector machines (SVMs, also support vector networks) are supervised learning models with associated learning algorithms that analyze data used for classification and regression analysis.  Given a set of training examples, each marked as belonging to one or the other of two categories, an SVM training algorithm builds a model that assigns new examples to one category or the other, making it a non-probabilistic binary linear classifier (although methods such as Platt scaling exist to use SVM in a probabilistic classification setting).  An SVM model is a representation of the examples as points in space, mapped so that the examples of the separate categories are divided by a clear gap that is as wide as possible.  New examples are then mapped into that same space and predicted to belong to a category based on which side of the gap they fall.

Category mistake: A category mistake, or category error, or categorical mistake, or mistake of category, is a semantic or ontological error in which things belonging to a particular category are presented as if they belong to a different category, or, alternatively, a property is ascribed to a thing that could not possibly have that property.  An example is the metaphor "time crawled", which if taken literally is not just false but a category mistake.  To show that a category mistake has been committed one must typically show that once the phenomenon in question is properly understood, it becomes clear that the claim being made about it could not possibly be true.

Phellodendron: Phellodendron, or cork-tree, is a genus of deciduous trees in the family Rutaceae, native to east and northeast Asia.  It has leathery, pinnate leaves and yellow, clumped flowers.  The name refers to the thick and corky bark of some (but not all) species in the genus.

Discrimination: In human social affairs, discrimination is treatment or consideration of, or making a distinction in favor of or against, a person based on the group, class, or category to which the person is perceived to belong rather than on individual attributes.  This includes treatment of an individual or group, based on their actual or perceived membership in a certain group or social category, "in a way that is worse than the way people are usually treated".  It involves the group's initial reaction or interaction going on to influence the individual's actual behavior towards the group leader or the group, restricting members of one group from opportunities or privileges that are available to another group, leading to the exclusion of the individual or entities based on logical or irrational decision making.

Boltonia: Boltonia is a genus of plants in the sunflower family native primarily to North America with one species in eastern Asia.
