SPACE MAPPING Meaning and
Definition
-
Space mapping refers to a technique or process used in various fields, particularly in engineering and optimization, to improve the performance and efficiency of a given system or process. It involves mapping or transforming the problem or design space from one domain to another in an effort to find a better solution or representation.
In engineering, space mapping is used to bridge the gap between low-fidelity and high-fidelity models or simulations. It is a method of constructing a surrogate model, typically using a simplified or coarse representation of the problem, which can then be used to quickly and efficiently evaluate the system's behavior or performance. The mapping process relates the input and output variables of the simplified model to those of the high-fidelity model, enabling the prediction of accurate responses without the need for computationally expensive simulations.
Space mapping is also used in optimization algorithms to explore the design space more effectively. By mapping the problem onto a transformed space, the algorithm can focus its search on regions that are expected to yield better solutions, leading to faster convergence and improved results. The mapping can be based on various principles, such as gradient information, pattern recognition, or Bayesian statistics, depending on the specific problem and the desired optimization objective.
Overall, space mapping is a powerful technique for improving the efficiency, accuracy, and convergence of systems and optimization processes by mapping the problem or design space from one domain to another.
Etymology of SPACE MAPPING
The word "space mapping" does not have a specific etymology as it is a compound term formed by combining the words "space" and "mapping". However, we can analyze the etymology of each component word:
1. Space: The word "space" originated from the Old French word "espace", which was derived from the Latin word "spatium". This Latin word referred to an area, extent, or distance.
2. Mapping: The word "mapping" is derived from the verb "to map". The term "map" came from the Medieval Latin word "mappa", which originally referred to a cloth or sheet used as a writing surface. This Latin word likely originated from an onomatopoeic representation of the sound made while folding or unfolding such a sheet.
