Question
You are creating a training pipeline for a regression model and your dataset contains hundreds of columns. For a particular part of your model, you want to use data only from some specific columns. Which module should you add to the pipeline?
A. Normalize data
B. Select columns in a dataset
C. Clean missing data
Answer
B. Select columns in a dataset
Explanation
This module is used to choose a subset of columns to use in downstream operations.
To use data only from specific columns in a training pipeline for a regression model, you should add the Select Columns in a Dataset module to the pipeline. This module allows you to select the columns you want to use in your model and exclude the rest. You can also rename columns, drop columns, or keep only the columns you want to use.
The Normalize Data module is used to normalize the data so that the values are all on a similar scale based relative to the minimum and maximum values in each column. The Clean Missing Data module is used to clean missing data by replacing missing values with a default value or by removing the rows or columns that contain missing values.
