Managing Diverse Data Types in a Dataset with COLUMNTRANSFER
Last updated: Monday, March 3, 2025
Published in: CODE Magazine: 2025 - Mar/Apr
Gaurav Mittal discusses efficient data preprocessing techniques for mixed-feature datasets, emphasizing the use of the `ColumnTransformer` from the SKLEARN.COMPOSE module. By showcasing a practical application with a dataset containing numerical, categorical, and unstructured text data, he demonstrates how the `ColumnTransformer` can streamline preprocessing tasks, reducing complexity and error potential. Key transformations include scaling numerical features, one-hot encoding categorical data, and vectorizing text. Gaurav elaborates on critical parameters like transformers and remainder, highlighting their role in ensuring each feature type undergoes suitable preprocessing, ultimately optimizing machine learning model performance.
