Taking unprocessed astronomical data and getting it in a more understandable form (e.g. calibrating it).
1. The transformation of raw data into a more applicable form. 2. The conversion of all information in a data set into fewer dimensions for a particular purpose, as, for example, a single measure such as a reliability measure.
The process of transforming large quantities of raw data, usually gathered by automatic recording equipment, into useful, condensed, or simplified information.
Lowers the amount of data needed to store music. Sony's MiniDisc uses an in-house system called ATRAC (Adaptive Transform Acoustic Coding) while the PASC (Precision Adaptive Sub-band Coding) used in Philips' DCCformat serves a similar function, removing signals its designers think you can't hear.
The process of checking, calibration, and preparation necessary to convert raw measurements into a form suitable for analysis and application.
Transformation of data values into useful, ordered, or simplified information.
any technique used to transform data from raw data into a more useful form of data. For example, grouping, summing, or averaging related data [ IEEE 90].
Conversion of observed values into useful, ordered and simplified information.
The process of turning data from astronomical instruments into measurements useful for doing science with. It is called "reduction" because you are usually taking large quantities of data (such as an entire image) and turning it into one or two useful numbers (such as the brightness of an object in the image).
process of transforming masses of raw data into useful, ordered, or simplified intelligence.
