Data Engineering

Question

A data scientist obtains a tabular dataset that contains 150 correlated features with different ranges to build a regression model. The data scientist needs to achieve more efficient model training by implementing a solution that minimizes impact on the model's performance. The data scientist decides to perform a principal component analysis (PCA) preprocessing step to reduce the number of features to a smaller set of independent features before the data scientist uses the new features in the regression model. Which preprocessing step will meet these requirements?

Options

  • AUse the Amazon SageMaker built-in algorithm for PCA on the dataset to transform the data.
  • BLoad the data into Amazon SageMaker Data Wrangler. Scale the data with a Min Max Scaler
  • CReduce the dimensionality of the dataset by removing the features that have the highest
  • DReduce the dimensionality of the dataset by removing the features that have the lowest
