Question 182:
You work as a machine learning specialist for an auto manufacturer. You are on a machine learning team that is responsible for analyzing the efficiency of potential electric car drive trains. These drivetrains have explicit energy storage requirements (regenerative braking) to help with efficiency when driving in cities. Your team is in the feature engineering phase of your model development. You need to produce visualizations to get an idea of which features are useful and which can be improved using dimensionality reduction. You have several data sources that you would like to visualize in your QuickSight environment. Which of your data sources cannot be directly used as data sources in QuickSight?
