Train an image classification model

This page shows you how to train an AutoML classification model from an image 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. For the training method, select AutoML.

  5. Click Continue.

  6. Enter a name for the model.

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

  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.

REST

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

  • LOCATION: Region where dataset is located and Model is created. For example, us-central1.
  • PROJECT: Your project ID.
  • TRAININGPIPELINE_DISPLAYNAME: Required. A display name for the trainingPipeline.
  • DATASET_ID: The ID number for the dataset to use for training.
  • fractionSplit: Optional. One of several possible ML use split options for your data. For fractionSplit, values must sum to 1. For example:
    • {"trainingFraction": "0.7","validationFraction": "0.15","testFraction": "0.15"}
  • MODEL_DISPLAYNAME*: A display name for the model uploaded (created) by the TrainingPipeline.
  • MODEL_DESCRIPTION*: A description for the model.
  • modelToUpload.labels*: Any set of key-value pairs to organize your models. For example:
    • "env": "prod"
    • "tier": "backend"
  • MODELTYPE: The type of Cloud-hosted model to train. The options are:
    • CLOUD (default)
  • NODE_HOUR_BUDGET: The actual training cost will be equal or less than this value. For Cloud models the budget must be: 8,000 - 800,000 milli node hours (inclusive). The default value is 192,000 which represents one day in wall time, assuming 8 nodes are used.
  • 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": "labels.aiplatform.googleapis.com/ml_use=training",
    "validationFilter": "labels.aiplatform.googleapis.com/ml_use=validation",
    "testFilter": "labels.aiplatform.googleapis.com/ml_use=test"
    }
