WebAn example machine learning pipeline that uses only PySpark and Kedro This Kedro starter uses the simple and familiar Iris dataset. It contains the code for an example machine learning pipeline that trains a random forest classifier to classify an iris. The pipeline includes two modular pipelines: one for data engineering and one for data science.
