It can be done by enabling a sequence of data to be transformed and correlated together in a model that can be analyzed to get the output. A typical pipeline includes raw data input, features, outputs, model parameters, ML models, and ...

WitrynaThe fit of an imputer has nothing to do with fit used in model fitting. So using imputer's fit on training data just calculates means of each column of training data. Using transform on test data then replaces missing values of test data with means that were calculated from training data. Share Improve this answer edited Jun 19, 2024 at 21:44 Ethan
