  2. Vectorization (mathematics) - Wikipedia

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

    Vectorization (mathematics) In mathematics, especially in linear algebra and matrix theory, the vectorization of a matrix is a linear transformation which converts the matrix into a vector. Specifically, the vectorization of a m × n matrix A, denoted vec ( A ), is the mn × 1 column vector obtained by stacking the columns of the matrix A on ...

  3. Vector graphics - Wikipedia

    en.wikipedia.org/wiki/Vector_graphics

    Vector graphics. Vector graphics are a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. The associated mechanisms may include vector display and printing hardware, vector data models and file formats, as well as the software ...

  4. Vectorization - Wikipedia

    en.wikipedia.org/wiki/Vectorization

    Array programming, a style of computer programming where operations are applied to whole arrays instead of individual elements. Automatic vectorization, a compiler optimization that transforms loops to vector operations. Image tracing, the creation of vector from raster graphics. Word embedding, mapping words to vectors, in natural language ...

  5. Feature hashing - Wikipedia

    en.wikipedia.org/wiki/Feature_hashing

    Feature hashing. In machine learning, feature hashing, also known as the hashing trick (by analogy to the kernel trick ), is a fast and space-efficient way of vectorizing features, i.e. turning arbitrary features into indices in a vector or matrix. [1] [2] It works by applying a hash function to the features and using their hash values as ...

  6. Image tracing - Wikipedia

    en.wikipedia.org/wiki/Image_tracing

    Erase stray marks and fill in lines and areas. Corel advice: Put the image on a light table, cover it with vellum ( tracing paper ), and then manually ink the desired outlines. Then scan the vellum and use an automated raster-to-vector conversion program on that scan.

  7. Automatic vectorization - Wikipedia

    en.wikipedia.org/wiki/Automatic_vectorization

    Automatic vectorization. Automatic vectorization, in parallel computing, is a special case of automatic parallelization, where a computer program is converted from a scalar implementation, which processes a single pair of operands at a time, to a vector implementation, which processes one operation on multiple pairs of operands at once.

    Supported OS (without emulation) CorelDRAW. Cascade Parent Limited. d.b.a Alludo. Formerly called the Corel Corporation. 1989. 2023 (version 24.3) $449, $169 upgrade. Proprietary.

  9. Vector space model - Wikipedia

    en.wikipedia.org/wiki/Vector_space_model

    Vector space model. Vector space model or term vector model is an algebraic model for representing text documents (or more generally, items) as vectors such that the distance between vectors represents the relevance between the documents. It is used in information filtering, information retrieval, indexing and relevancy rankings.
