Feature engineering plays a vital role in big data analytics. Machine learning and data mining algorithms cannot work without data. Little can be achieved if there are few features to represent the underlying data objects, and the quality of results of those algorithms largely depends on the quality of the available features.Photo by Susan Holt Simpson on Unsplash. Feature Encoding converts categorical variables to numerical variables as part of the feature engineering step to make the data compatible with Machine Learning models. There are various ways to perform feature encoding, depending on the type of categorical variable and other considerations. ….
