pre-processing
Before the analysis
Pre-processing is preparation performed on data before the main analysis or operation begins.
In computing and data science, raw data often needs cleaning, formatting, or transformation before algorithms can work with it effectively: The images required extensive pre-processing before the model could be trained.
The term appears in any field where inputs must be standardized or refined before primary work proceeds.
