Explain MATRIX: (Plural: matrices) An older Webster’s dictionary with a heavier emphasis on typographical representation gives the mathematical definition as “a set of numbers or terms arranged in rows and columns between parentheses or double lines”[websters]. For purposes of manipulating a matrix with software, think of it as a two-dimensional array. As with its one-dimensional equivalent, a vector, this mathematical representation of the two-dimensional array makes it easier to take advantage of software libraries that apply advanced mathematical operations to the data—including libraries that can distribute the processing across multiple processors for scalability. See also vector, linear algebra.
Different definitions in web development like matrix in Dictionary M.
- Manual Machine Learning:
- Meaning driven algorithms that perform better as they have more data to work with, “learning” (that is, refining their models) from this additional data. This often involves cross-validation with training matrix definition.
- Manual Median:
- Meaning When values are sorted, the value in the middle, or the average of the two in the middle if there are an even number of values. See also mean, mode matrix explain.
- Manual Mean:
- Meaning The average value, although technically that is known as the “arithmetic mean.” (Other means include the geometric and harmonic means.) See also median, mode matrix what is.
- Manual Mean Absolute Error:
- Meaning Also, MAE. The average error of all predicted values when compared with observed values. See also Mean Squared Error, Root Mean Squared Error matrix meaning.
- Manual Monte Carlo Method:
- Meaning of randomly generated numbers as part of an algorithm. Its use with Markov Chains is so popular that people usually refer to the combination with the acronym MCMC. See also Markov Chain matrix abbreviation.
