Train a video object tracking model

This page shows you how to train an AutoML object tracking model from a video dataset using either the Google Cloud console or the Vertex AI API.

Train an AutoML model

Google Cloud console

  1. In the Google Cloud console, in the Vertex AI section, go to the Datasets page.

    Go to the Datasets page

  2. Click the name of the dataset you want to use to train your model to open its details page.

  3. Click Train new model.

  4. Enter the display name for your new model.

  5. If you want manually set how your training data is split, expand Advanced options and select a data split option. Learn more.

  6. Click Continue.

  7. Select the model training method.

    • AutoML is a good choice for a wide range of use cases.
    • Seq2seq+ is a good choice for experimentation. The algorithm is likely to converge faster than AutoML because its architecture is simpler and it uses a smaller search space. Our experiments find that Seq2Seq+ performs well with a small time budget and on datasets smaller than 1 GB in size.
    Click Continue.

  8. Click Start Training.

    Model training can take many hours, depending on the size and complexity of your data and your training budget, if you specified one. You can close this tab and return to it later. You will receive an email when your model has completed training.

    Several minutes after training starts, you can check the training node hour estimation from the model's properties information. If you cancel the training, there is no charge on the current product.

Before using any of the request data, make the following replacements:

  • LOCATION: Region where Dataset is located and Model will be stored. For example, us-central1.
  • PROJECT: Your project ID.
  • MODEL_DISPLAY_NAME: Display name for the newly trained model.
  • DATASET_ID: ID for the training Dataset.
  • The filterSplit object is optional; you use it to control your data split. For more information about controlling data split, see Controlling the data split using REST.
  • PROJECT_NUMBER: Your project's automatically generated project number

Control the data split using REST

You can control how your training data is split between the training, validation, and test sets. When using the Vertex AI API, use the Split object to determine your data split. The Split object can be included in the InputConfig object as one of several object types, each of which provides a different way to split the training data. You can select one method only.

  • FractionSplit:
    • TRAINING_FRACTION: The fraction of the training data to be used for the training set.
    • VALIDATION_FRACTION: The fraction of the training data to be used for the validation set. Not used for video data.
    • TEST_FRACTION: The fraction of the training data to be used for the test set.

    If any of the fractions are specified, all must be specified. The fractions must add up to 1.0. The default values for the fractions differ depending on your data type. Learn more.

    "fractionSplit": {
      "trainingFraction": TRAINING_FRACTION,
      "validationFraction": VALIDATION_FRACTION,
      "testFraction": TEST_FRACTION
  • FilterSplit:
    • TRAINING_FILTER: Data items that match this filter are used for the training set.
    • VALIDATION_FILTER: Data items that match this filter are used for the validation set. Must be "-" for video data.
    • TEST_FILTER: Data items that match this filter are used for the test set.

    These filters can be used with the ml_use label, or with any labels you apply to your data. Learn more about using the ml-use label and other labels to filter your data.

    The following example shows how to use the filterSplit object with the ml_use label, with the validation set included:

    "filterSplit": {
    "trainingFilter": "",
    "validationFilter": "",
    "testFilter": ""
