2024/02/21 - Amazon Lookout for Equipment - 5 updated api methods
Changes This release adds a field exposing model quality to read APIs for models. It also adds a model quality field to the API response when creating an inference scheduler.
{'ModelQuality': 'QUALITY_THRESHOLD_MET | CANNOT_DETERMINE_QUALITY | '
'POOR_QUALITY_DETECTED'}
Creates a scheduled inference. Scheduling an inference is setting up a continuous real-time inference plan to analyze new measurement data. When setting up the schedule, you provide an S3 bucket location for the input data, assign it a delimiter between separate entries in the data, set an offset delay if desired, and set the frequency of inferencing. You must also provide an S3 bucket location for the output data.

string
[REQUIRED]
The name of the previously trained machine learning model being used to create the inference scheduler.
string
[REQUIRED]
The name of the inference scheduler being created.
integer
The interval (in minutes) of planned delay at the start of each inference segment. For example, if inference is set to run every ten minutes, the delay is set to five minutes and the time is 09:08. The inference scheduler will wake up at the configured interval (which, without a delay configured, would be 09:10) plus the additional five minute delay time (so 09:15) to check your Amazon S3 bucket. The delay provides a buffer for you to upload data at the same frequency, so that you don't have to stop and restart the scheduler when uploading new data.
For more information, see Understanding the inference process .
string
[REQUIRED]
How often data is uploaded to the source Amazon S3 bucket for the input data. The value chosen is the length of time between data uploads. For instance, if you select 5 minutes, Amazon Lookout for Equipment will upload the real-time data to the source bucket once every 5 minutes. This frequency also determines how often Amazon Lookout for Equipment runs inference on your data.
For more information, see Understanding the inference process .

Indicates how this model version was generated.
ModelQuality (string) --
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 .

Response Structure
(dict) --
NextToken (string) --
An opaque pagination token indicating where to continue the listing of machine learning models.
ModelSummaries (list) --
Provides information on the specified model, including created time, model and dataset ARNs, and status.
(dict) --
Provides information about the specified machine learning model, including dataset and model names and ARNs, as well as status.
ModelName (string) --
The name of the machine learning model.
ModelArn (string) --
The Amazon Resource Name (ARN) of the machine learning model.
DatasetName (string) --
The name of the dataset being used for the machine learning model.
DatasetArn (string) --
The Amazon Resource Name (ARN) of the dataset used to create the model.
Status (string) --
Indicates the status of the machine learning model.
CreatedAt (datetime) --
The time at which the specific model was created.
ActiveModelVersion (integer) --
The model version that the inference scheduler uses to run an inference execution.
ActiveModelVersionArn (string) --
The Amazon Resource Name (ARN) of the model version that is set as active. The active model version is the model version that the inference scheduler uses to run an inference execution.
LatestScheduledRetrainingStatus (string) --
Indicates the status of the most recent scheduled retraining run.
LatestScheduledRetrainingModelVersion (integer) --
Indicates the most recent model version that was generated by retraining.
LatestScheduledRetrainingStartTime (datetime) --
Indicates the start time of the most recent scheduled retraining run.
NextScheduledRetrainingStartDate (datetime) --
Indicates the date that the next scheduled retraining run will start on. Lookout for Equipment truncates the time you provide to the nearest UTC day .
RetrainingSchedulerStatus (string) --
Indicates the status of the retraining scheduler.
ModelDiagnosticsOutputConfiguration (dict) --
Output configuration information for the pointwise model diagnostics for an Amazon Lookout for Equipment model.
S3OutputConfiguration (dict) --
The Amazon S3 location for the pointwise model diagnostics.
Bucket (string) --
The name of the Amazon S3 bucket where the pointwise model diagnostics are located. You must be the owner of the Amazon S3 bucket.
Prefix (string) --
The Amazon S3 prefix for the location of the pointwise model diagnostics. The prefix specifies the folder and evaluation result file name. (bucket ).
When you call CreateModel or UpdateModel , specify the path within the bucket that you want Lookout for Equipment to save the model to. During training, Lookout for Equipment creates the model evaluation model as a compressed JSON file with the name model_diagnostics_results.json.gz .
When you call DescribeModel or DescribeModelVersion , prefix contains the file path and filename of the model evaluation file.
KmsKeyId (string) --
The Amazon Web Services Key Management Service (KMS) key identifier to encrypt the pointwise model diagnostics files.
ModelQuality (string) --
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.
