pre-process
Treat data first
Pre-process means to prepare data or materials through preliminary treatment before the main operation.
In computing, pre-processing transforms raw input—cleaning, formatting, or organizing it—before analysis or compilation: The script pre-processes the images before feeding them to the neural network.
In manufacturing, pre-processing might involve sorting, washing, or treating materials.
The noun preprocessing (often unhyphenated) names this preparatory stage.
