Data preprocessing is the set of techniques used to clean and prepare raw data for analysis or machine learning, including handling missing values, removing duplicates, normalizing scales, and encoding categorical variables. Data scientists perform preprocessing as an early, critical step in any analytics or modeling pipeline, since the quality of input data heavily influences the accuracy of downstream results. Common preprocessing tasks include outlier detection, feature scaling, and text tokenization for NLP tasks.
