Automated Labeling Tools

This guide is a continuation of the Labeling Events of Interest Documentation. Now that you’ve learned the basics of how to add segments to a session let’s go over some of the automated labeling tools within the Data Capture Lab. There are two main tools you can use to automate the labeling process.

  1. Using a model/Knowledge Pack from the Analytics Studio

  2. Using a segmentation algorithm in an auto-session

Using a Model/Knowledge Pack from the Analytics Studio

After you build a model/Knowledge Pack to recognize your events in the Analytics Studio you can use that model within the Data Capture Lab to label your events on any previously collected file in your project. This is a powerful tool that greatly speeds up the time to label a project and also lets you see how your model will perform without needing to re-collect new data.

  1. Open the Project Explorer

  1. Select the files you want to use by holding (Shift + Click) or (Ctrl + Click)

  2. Right-Click and select Segments → Add → From Knowledge Pack

  1. Select a Knowledge Pack

  1. Select a Session. This is where the Knowledge Pack results will be saved

  1. Save the results. (Optional: You can edit or delete the Knowledge Pack results before saving)

Using a Segmentation Algorithm in an Auto-Session

In the Labeling Events of Interest Documentation we went over how to manually place a segment around your event of interest. However, you can setup a segmentation algorithm in an auto-session to automate labeling your events of interest without needing to manually place segments.

  1. Create an auto-session by clicking the + icon in the Session control at the bottom of the Project Explorer

  1. Select the Auto setting type and click Add

  1. Select an Algorithm. The Data Capture Lab has access to five segmentation algorithms

  1. Learn more about how to use the segmentation algorithm by hovering over the info icon

  1. Enter your Session Parameters and click Save

  1. Select the files you want to use by holding (Shift + Click) or (Ctrl + Click)

  2. Right-Click and select Segments → Add → From Segmenter Algorithm

  1. Select your session and click Next

  1. The Data Capture Lab will use the algorithm in your session to create segments in the files you selected. Edit the labels and click Save
