  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    In 493 AD, Victorius of Aquitaine wrote a 98-column multiplication table which gave (in Roman numerals) the product of every number from 2 to 50 times and the rows were "a list of numbers starting with one thousand, descending by hundreds to one hundred, then descending by tens to ten, then by ones to one, and then the fractions down to 1/144 ...

  3. Word2vec - Wikipedia

    en.wikipedia.org/wiki/Word2vec

    Word2vec was created, patented, [7] and published in 2013 by a team of researchers led by Mikolov at Google over two papers. [1] [2] The original paper was rejected by reviewers for ICLR conference 2013. It also took months for the code to be approved for open-sourcing. [8] Other researchers helped analyse and explain the algorithm. [4]

  4. Apache Spark - Wikipedia

    en.wikipedia.org/wiki/Apache_Spark

    Spark Core is the foundation of the overall project. It provides distributed task dispatching, scheduling, and basic I/O functionalities, exposed through an application programming interface (for Java, Python, Scala, .NET [16] and R) centered on the RDD abstraction (the Java API is available for other JVM languages, but is also usable for some other non-JVM languages that can connect to the ...

  5. OLAP cube - Wikipedia

    en.wikipedia.org/wiki/OLAP_cube

    A Slice is a term for a subset of the data, generated by picking a value for one dimension and only showing the data for that value (for instance only the data at one point in time). Spreadsheets are only 2-dimensional, so by (continued) slicing or other techniques, it becomes possible to visualise multidimensional data in them.

  6. Normalization (statistics) - Wikipedia

    en.wikipedia.org/wiki/Normalization_(statistics)

    In another usage in statistics, normalization refers to the creation of shifted and scaled versions of statistics, where the intention is that these normalized values allow the comparison of corresponding normalized values for different datasets in a way that eliminates the effects of certain gross influences, as in an anomaly time series. Some ...

  7. Double fertilization - Wikipedia

    en.wikipedia.org/wiki/Double_fertilization

    The mature embryonic sac of an unfertilized ovule is 7-cellular and 8-nucleate. It is arranged in the form of 3+1+3 (from top to bottom) i.e. 3 antipodal cells, 1 central cell (binucleate), 2 synergids & 1 egg cell. One sperm fertilizes the egg cell and the other sperm fuses with the two polar nuclei of

  8. Type 3 innate lymphoid cells - Wikipedia

    en.wikipedia.org/wiki/Type_3_innate_lymphoid_cells

    ILC 3 may play a role already in the prenatal setting of the body's resistance to infections. LTi cells are important in the origin and development of secondary lymphoid organs. It has been found that differentiation and signalling of LTi cells are dependent on retinoic acid (a component of vitamin A). The uptake of retinoic acid in the diet by ...

  9. Data proliferation - Wikipedia

    en.wikipedia.org/wiki/Data_proliferation

    For businesses with more than 10 employees, this increases to almost two hours per week at $5,760 per year. [5] In large networks of primary and secondary data storage, problems finding electronic data are analogous to problems finding hard copy data.
