 ** ModelArn **   <a name="LookoutForEquipment-Type-ModelVersionSummary-ModelArn"></a>
The Amazon Resource Name (ARN) of the model that this model version is a version of.  
Type: String  
Length Constraints: Minimum length of 20. Maximum length of 2048.  
Pattern: `arn:aws(-[^:]+)?:lookoutequipment:[a-zA-Z0-9\-]*:[0-9]{12}:model\/.+`

 ** ModelName **   <a name="LookoutForEquipment-Type-ModelVersionSummary-ModelName"></a>
The name of the model that this model version is a version of.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 200.

 ** ModelQuality **   <a name="LookoutForEquipment-Type-ModelVersionSummary-ModelQuality"></a>
Provides a quality assessment for a model that uses labels. If Lookout for Equipment determines that the model quality is poor based on training metrics, the value is `POOR_QUALITY_DETECTED`. Otherwise, the value is `QUALITY_THRESHOLD_MET`.   
If the model is unlabeled, the model quality can't be assessed and the value of `ModelQuality` is `CANNOT_DETERMINE_QUALITY`. In this situation, you can get a model quality assessment by adding labels to the input dataset and retraining the model.  
For information about improving the quality of a model, see [Best practices with Amazon Lookout for Equipment](https://docs.aws.amazon.com/lookout-for-equipment/latest/ug/best-practices.html).
