Description

Updates an existing machine learning transform. Call this operation to tune the algorithm parameters to achieve better results. After calling this operation, you can call the StartMLEvaluationTaskRun operation to assess how well your new parameters achieved your goals (such as improving the quality of your machine learning transform, or making it more cost-effective).

Parameters

-Description <String>
A description of the transform. The default is an empty string.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-FindMatchesParameters_AccuracyCostTradeoff <Double>
The value that is selected when tuning your transform for a balance between accuracy and cost. A value of 0.5 means that the system balances accuracy and cost concerns. A value of 1.0 means a bias purely for accuracy, which typically results in a higher cost, sometimes substantially higher. A value of 0.0 means a bias purely for cost, which results in a less accurate FindMatches transform, sometimes with unacceptable accuracy.Accuracy measures how well the transform finds true positives and true negatives. Increasing accuracy requires more machine resources and cost. But it also results in increased recall. Cost measures how many compute resources, and thus money, are consumed to run the transform.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesParameters_FindMatchesParameters_AccuracyCostTradeoff
-FindMatchesParameters_EnforceProvidedLabel <Boolean>
The value to switch on or off to force the output to match the provided labels from users. If the value is True, the find matches transform forces the output to match the provided labels. The results override the normal conflation results. If the value is False, the find matches transform does not ensure all the labels provided are respected, and the results rely on the trained model.Note that setting this value to true may increase the conflation execution time.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesParameters_FindMatchesParameters_EnforceProvidedLabels
-FindMatchesParameters_PrecisionRecallTradeoff <Double>
The value selected when tuning your transform for a balance between precision and recall. A value of 0.5 means no preference; a value of 1.0 means a bias purely for precision, and a value of 0.0 means a bias for recall. Because this is a tradeoff, choosing values close to 1.0 means very low recall, and choosing values close to 0.0 results in very low precision.The precision metric indicates how often your model is correct when it predicts a match. The recall metric indicates that for an actual match, how often your model predicts the match.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesParameters_FindMatchesParameters_PrecisionRecallTradeoff
-FindMatchesParameters_PrimaryKeyColumnName <String>
The name of a column that uniquely identifies rows in the source table. Used to help identify matching records.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesParameters_FindMatchesParameters_PrimaryKeyColumnName
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-GlueVersion <String>
This value determines which version of AWS Glue this machine learning transform is compatible with. Glue 1.0 is recommended for most customers. If the value is not set, the Glue compatibility defaults to Glue 0.9. For more information, see AWS Glue Versions in the developer guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-MaxCapacity <Double>
The number of AWS Glue data processing units (DPUs) that are allocated to task runs for this transform. You can allocate from 2 to 100 DPUs; the default is 10. A DPU is a relative measure of processing power that consists of 4 vCPUs of compute capacity and 16 GB of memory. For more information, see the AWS Glue pricing page. When the WorkerType field is set to a value other than Standard, the MaxCapacity field is set automatically and becomes read-only.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-MaxRetry <Int32>
The maximum number of times to retry a task for this transform after a task run fails.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

-Name <String>
The unique name that you gave the transform when you created it.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NumberOfWorker <Int32>
The number of workers of a defined workerType that are allocated when this task runs.

Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the TransformId parameter. The -PassThru parameter is deprecated, use -Select '^TransformId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Role <String>
The name or Amazon Resource Name (ARN) of the IAM role with the required permissions.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'TransformId'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.Glue.Model.UpdateMLTransformResponse). Specifying the name of a property of type Amazon.Glue.Model.UpdateMLTransformResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Timeout <Int32>
The timeout for a task run for this transform in minutes. This is the maximum time that a task run for this transform can consume resources before it is terminated and enters TIMEOUT status. The default is 2,880 minutes (48 hours).

Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage.

Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>

-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
