Applying Preprocessing Components to Data

You can apply preprocessing components to your data, such as filters, before performing an analysis.

This is an optional step.

In many cases, the raw data from the data source may not be suitable for analysis. For accurate results, you may need to prepare and process the data before analysis. You can find data manipulation functions in the Prepare room and data preparation functions in the Predict room. In the Prepare room, you can work on the static data or raw data that is imported into Expert Analytics. In the Predict room, you can work on the transient data using preprocessor components.

Data preparation involves checking data for accuracy and missing fields, filtering data based on range values, sampling the data to investigate a subset of data, and manipulating data. You can process data using data preparation components.

  1. In the Predict room, double-click the required preprocessor component under the list of components on the right.
    The preprocessor component is added to the analysis editor and an automatic connection is created to the data source component.
  2. From the contextual menu of the preprocessor component and choose Configure Properties.
  3. In the component properties dialog box, enter the necessary details for the preprocessor component properties.
  4. Choose Done.
  5. To view the results of the analysis, choose (Run Analysis).
