INFORMATION MEASURE Meaning and
Definition
-
An information measure refers to a mathematical or quantitative representation of the amount of information contained within a message or a data set. It is used to quantify the uncertainty or the degree of predictability associated with the information.
In the field of information theory, an information measure is typically expressed in terms of "bits" or "shannons," which refer to the fundamental units of information. The measure quantifies the level of surprise or unpredictability of an event or symbol, with low values indicating high predictability, and high values indicating high uncertainty.
Information measures are utilized in various contexts, such as data compression, cryptography, machine learning, and signal processing. They enable the evaluation and comparison of different encoding schemes or algorithms by determining the efficiency with which information can be transmitted or stored.
Common types of information measures include entropy, mutual information, and relative entropy (also known as Kullback-Leibler divergence). Entropy, for instance, calculates the average amount of information per symbol or data point in a data set, while mutual information measures the degree of association or dependence between two variables. Relative entropy quantifies the difference between two probability distributions.
Overall, an information measure serves as a valuable tool to numerically express and analyze the informational content or structure of data, providing insights into various aspects of communication, data analysis, and decision-making processes.

Etymology of INFORMATION MEASURE
The etymology of the word "information measure" can be broken down as follows:
1. Information: The word "information" originates from the Latin word "informare", which means "to give form to" or "to shape". In the 14th century, it started to be used in English to refer to knowledge communicated, news, or details about something.
2. Measure: The word "measure" comes from the Old French word "mesure", which is derived from the Latin word "mensura", meaning "a measuring, measurement". It can also be traced back to the Latin word "metiri", meaning "to measure" or "to estimate".
When combined, "information measure" refers to a quantitative representation or quantification of the amount of information contained or conveyed by a certain message, signal, or data. This term is commonly used in fields such as information theory, statistics, and data analysis.
