  2. Glossary of mathematical jargon - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_mathematical...

    In applied fields the word "tight" is often used with the same meaning. [2] smooth Smoothness is a concept which mathematics has endowed with many meanings, from simple differentiability to infinite differentiability to analyticity, and still others which are more complicated. Each such usage attempts to invoke the physically intuitive notion ...

  3. Applied mathematics - Wikipedia

    en.wikipedia.org/wiki/Applied_mathematics

    Applied mathematics is the application of mathematical methods by different fields such as physics, engineering, medicine, biology, finance, business, computer science, and industry. Thus, applied mathematics is a combination of mathematical science and specialized knowledge.

    2. Equivalence class: given an equivalence relation, [] often denotes the equivalence class of the element x. 3. Integral part: if x is a real number, [] often denotes the integral part or truncation of x, that is, the integer obtained by removing all digits after the decimal mark.

  5. Word problem (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Word_problem_(mathematics)

    [35] [36] The equivalence classes of W(X)/~ are the sets of all words w and v with w ≤ ~ v and v ≤ ~ w. Two well-formed words v and w in W ( X ) denote the same value in every bounded lattice if and only if w ≤ ~ v and v ≤ ~ w ; the latter conditions can be effectively decided using the above inductive definition.

  6. List of axioms - Wikipedia

    en.wikipedia.org/wiki/List_of_axioms

    This is a list of axioms as that term is understood in mathematics. In epistemology, the word axiom is understood differently; see axiom and self-evidence. Individual axioms are almost always part of a larger axiomatic system.

  7. Multiclass classification - Wikipedia

    en.wikipedia.org/wiki/Multiclass_classification

    In machine learning and statistical classification, multiclass classification or multinomial classification is the problem of classifying instances into one of three or more classes (classifying instances into one of two classes is called binary classification). For example, deciding on whether an image is showing a banana, an orange, or an ...

  9. Mathematics - Wikipedia

    en.wikipedia.org/wiki/Mathematics

    [111] [115] This led to split mathematics into pure mathematics and applied mathematics, the latter being often considered as having a lower value among mathematical purists. However, the lines between the two are frequently blurred. [116] The aftermath of World War II led to a surge in the development of applied mathematics in the US and ...
