Normalization

Normalization or normalisation may refer to:

Mathematics and statistics

• Normalization (statistics), adjustments of values or distributions in statistics
  • Quantile normalization, statistical technique for making two distributions identical in statistical properties
• Normalizing (abstract rewriting), an abstract rewriting system in which every object has at least one normal form
  • Normalization property (abstract rewriting), a property of a rewrite system in mathematical logic and theoretical computer science
• Normalizing constant, in probability theory a constant to make a non-negative function a probability density function
• Noether normalization lemma, result of commutative algebra
• The process of obtaining a normalized vector
• Normalized number, adjusting a floating point number's exponent so that the decimal point is in a fixed position

Science

• Normalization (sociology) or social normalization, the process through which ideas and actions are made to appear culturally "normal"
• Normalization model, used in visual neuroscience
• Normalisable wave function, in quantum mechanics a wave function normalized for probability distribution
• Normalization process theory, a sociological theory of the implementation of new technologies or innovations
• Numéraire, a basic standard by which value is computed

Technology

• Normalization (image processing), changing the range of pixel intensity values
• Normalized frequency (digital signal processing), unit of frequency cycles/sample in digital signal processing
