## Feature The following BigQuery ML data preprocessing features are now in[preview](https://cloud.google.com/products/#product-launch-stages): * The[ML.TRANSFORM function](https://cloud.google.com/bigquery/docs/reference/standard-sql/bigqueryml-syntax-transform), which you can use to preprocess feature data. This function processes input data by applying the data transformations captured in the[TRANSFORM clause](https://cloud.google.com/bigquery/docs/reference/standard-sql/bigqueryml-syntax-create#transform)of an existing model. * [Transform-only models](https://cloud.google.com/bigquery/docs/reference/standard-sql/bigqueryml-syntax-create-transform)which you can use to apply[preprocessing functions](https://cloud.google.com/bigquery/docs/manual-preprocessing)to input data and return the preprocessed data. Transform-only models decouple data preprocessing from model training, making it easier for you to capture and reuse a set of data preprocessing rules.
