Automation efficiency score

Automation efficiency score is a proprietary metric that Labelbox calculates to help you better understand how well you are using automation to improve your labeling efficiency. Labelbox calculates this metric by using your project data and normalizing it against benchmark data gathered from automation projects across all Labelbox customers.

The automation efficiency score will automatically start appearing in the Automation tab of your projects once the following conditions have been met:

  • You have labeled at least 10 data rows without using model-assisted labeling
  • You have imported at least 1 batch of labels as pre-labels using model-assisted labeling
  • You have labeled at least 10 data rows with the model-assisted labeling pre-labels

How to interpret efficiency scores

Using our historical project data, we are able to bucket projects using labeling automation into several tiers. Those tiers along with their average time savings are shown in the table below.

Score RangeCategoryAverage time savings per label*
76-100World Class65%
1-25Needs Improvement0%
  • Note: These are average time savings over the projects in the score range. We cannot guarantee that all projects can achieve these levels of time savings within the score range due to a variety of factors like ontology complexity, asset type, and task difficulty.

Efficiency score calculation

The automation efficiency score is a proprietary calculation but is heavily influenced by:

  • Percentage of features made with automation: This is the percentage of features in the project that were created with automation. This includes both unedited and edited features submitted that originally came through a model-assisted labeling import.
  • Estimated percent time saved per label using automation: This is calculated by comparing the average time spent labeling using automation to the average time spent labeling without using automation.
  • Total time savings saved across the project: This is the total time saved across the project's lifetime. This has a very minimal impact on the score but projects with larger aggregate time savings will see slightly high scores.

Tips for improving efficiency score

In general, we have seen two ways at improving the automation efficiency score (and thus see an improvement in labeling efficiency):

Increase the number of features made with automation
The most obvious way to improve your labeling efficiency is to simplify and increase the number of features you are uploading as pre-labels. This can include importing pre-labels for more features in your ontology or importing more low-confidence predictions as pre-labels.

Improve the model used to generate the pre-labels
By focusing on iterating on your model, you will see a gradual improvement in your pre-labels over time as your model accuracy improves.
