Manage QA processes

How helps to streamline QA, how to set up a linting process and which additional features can be leveraged

Use short feedback loops

The platform ensures short feedback loops through the following design choices:

  1. Labelers are not able to manually select samples to label first. Through the "Start Labeling" workflow, samples are presented for them.

  2. After a reviewer has rejected a sample, the original labeler has to correct the rejected sample before being able to continue labeling any other samples in the queue. The rejected sample will appear in the beginning of the labeler's queue. For more details about the label queue, see Label queue mechanics

  3. After a labeler has corrected a rejected sample, the original reviewer has to review the corrected sample. The corrected sample will appear in the beginning of the reviewer's queue.

Set up a linting process

Linting is the process of performing static analysis to flag erroneous patterns. For example, one would want to programmatically ...

  1. Identify cuboids with unexpected dimensions or positions

  2. Spot too small segmentation masks or uncover unlabeled pixels

  3. Observe movement errors in sequences

  4. Flag incorrect categories

Using the API/SDK & webhooks system, it is straightforward to set up such linting process and verify labels against expected properties:

  • The webhooks system allows to receive event notifications whenever a sample has been labeled, such that the linting process can be triggered (see also Set up webhooks)

  • The API/SDK offers a programmatic way to (see also Python SDK quickstart)

    • List & pull labels

    • Verify properties for these labels

    • Change the status of labels to e.g. "Rejected"

    • Report issues
