BigQuery Model

A BigQuery Model in Google Cloud is a managed machine learning resource that allows users to train, store, and use ML models directly within BigQuery using SQL. It supports various model types such as linear regression, logistic regression, and boosted trees, enabling large-scale data analysis and prediction without moving data outside BigQuery.

Fields

TitleIDTypeData TypeDescription
_keycorestring
ancestorscorearray<string>
best_trial_idcoreint64The best trial_id across all training runs.
creation_timecoreint64Output only. The time when this model was created, in millisecs since the epoch.
datadog_display_namecorestring
default_trial_idcoreint64Output only. The default trial_id to use in TVFs when the trial_id is not passed in. For single-objective [hyperparameter tuning](https://cloud.google.com/bigquery-ml/docs/reference/standard-sql/bigqueryml-syntax-hp-tuning-overview) models, this is the best trial ID. For multi-objective [hyperparameter tuning](https://cloud.google.com/bigquery-ml/docs/reference/standard-sql/bigqueryml-syntax-hp-tuning-overview) models, this is the smallest trial ID among all Pareto optimal trials.
descriptioncorestringOptional. A user-friendly description of this model.
encryption_configurationcorejsonCustom encryption configuration (e.g., Cloud KMS keys). This shows the encryption configuration of the model data while stored in BigQuery storage. This field can be used with PatchModel to update encryption key for an already encrypted model.
etagcorestringOutput only. A hash of this resource.
expiration_timecoreint64Optional. The time when this model expires, in milliseconds since the epoch. If not present, the model will persist indefinitely. Expired models will be deleted and their storage reclaimed. The defaultTableExpirationMs property of the encapsulating dataset can be used to set a default expirationTime on newly created models.
feature_columnscorejsonOutput only. Input feature columns for the model inference. If the model is trained with TRANSFORM clause, these are the input of the TRANSFORM clause.
friendly_namecorestringOptional. A descriptive name for this model.
hparam_search_spacescorejsonOutput only. All hyperparameter search spaces in this model.
hparam_trialscorejsonOutput only. Trials of a [hyperparameter tuning](https://cloud.google.com/bigquery-ml/docs/reference/standard-sql/bigqueryml-syntax-hp-tuning-overview) model sorted by trial_id.
label_columnscorejsonOutput only. Label columns that were used to train this model. The output of the model will have a "predicted_" prefix to these columns.
labelscorearray<string>The labels associated with this model. You can use these to organize and group your models. Label keys and values can be no longer than 63 characters, can only contain lowercase letters, numeric characters, underscores and dashes. International characters are allowed. Label values are optional. Label keys must start with a letter and each label in the list must have a different key.
last_modified_timecoreint64Output only. The time when this model was last modified, in millisecs since the epoch.
locationcorestringOutput only. The geographic location where the model resides. This value is inherited from the dataset.
model_referencecorejsonRequired. Unique identifier for this model.
model_typecorestringOutput only. Type of the model resource.
optimal_trial_idscorearray<int64>Output only. For single-objective [hyperparameter tuning](https://cloud.google.com/bigquery-ml/docs/reference/standard-sql/bigqueryml-syntax-hp-tuning-overview) models, it only contains the best trial. For multi-objective [hyperparameter tuning](https://cloud.google.com/bigquery-ml/docs/reference/standard-sql/bigqueryml-syntax-hp-tuning-overview) models, it contains all Pareto optimal trials sorted by trial_id.
