Key Differences
Discretization is the American English spelling of the process by which continuous variables, functions, or models are divided into discrete, distinct parts. This term is commonly used in mathematics, physics, and computer science to simplify problems and make them more manageable for numerical analysis. On the other hand, discretisation is the British English spelling of the same concept, reflecting the different orthographic conventions between American and British English.
While discretization emphasizes the transformation of continuous phenomena into a finite set of discrete states or values, enabling computational models to simulate and solve complex problems, discretisation serves the same purpose in regions that follow British spelling rules. Both terms involve breaking down a continuous domain or set of values into smaller, countable segments, crucial for digital computation and analysis.
The choice between discretization and discretisation usually depends on the regional or institutional preferences for American or British English, rather than any difference in meaning or application. Thus, while American journals, textbooks, and professionals might predominantly use discretization, their British counterparts are likely to prefer discretisation.
In scientific literature and academic writing, the preference for discretization or discretisation can also indicate the origin or target audience of the material. While the underlying principles and applications of discretization/discretisation remain consistent across disciplines, the spelling variants signal adherence to either American or British English standards.
Despite the orthographic differences, both terms are understood and accepted in scientific communities worldwide, indicating the global nature of the concepts they describe. Whether one encounters discretization or discretisation, the context and applications—ranging from numerical analysis to machine learning—remain universally recognized.
