Chapter 3: Data Preparation with SageMaker Data Wrangler
With SageMaker Data Wrangler, you can perform exploratory data analysis and data preprocessing for ML modeling with a point and click experience. You will be able to quickly iterate through data transformation and quick modeling to see if your transform recipe improves model performance, learning if there is implicit bias in the data against sensitive groups, and having a clear record of what transformation has been done on the processed data.
In this chapter, we will be learning how to use SageMaker Data Wrangler in the following sections:
- Getting started with SageMaker Data Wrangler for customer churn prediction
- Importing data from sources
- Exploring data with visualization
- Applying transformation
- Exporting data for ML training
