Question
You are creating a training pipeline for a regression model and you want to make sure that the dataset is complete, otherwise you need to perform various operations to fix the data. Which module should you add to the pipeline?
A. Select columns in a dataset
B. Clean missing data
C. Normalize data
Answer
B. Clean missing data
Explanation
Clean missing data helps to check data for missing values and then perform various operations to fix the data or insert new values. The goal of such cleaning operations is to prevent problems caused by missing data that can arise when training a model.
The correct answer is B. Clean missing data. This module allows you to handle missing values in your dataset by either removing them or replacing them with a specified value. Missing values can affect the performance and accuracy of your regression model, so it is important to check and fix them before training. The other two modules are not related to handling missing values, but rather to selecting or transforming the features in your dataset.
