CreateModel - Amazon Lookout for Equipment

CreateModel

Creates a machine learning model for data inference.

A machine-learning (ML) model is a mathematical model that finds patterns in your data. In Amazon Lookout for Equipment, the model learns the patterns of normal behavior and detects abnormal behavior that could be potential equipment failure (or maintenance events). The models are made by analyzing normal data and abnormalities in machine behavior that have already occurred.

Your model is trained using a portion of the data from your dataset and uses that data to learn patterns of normal behavior and abnormal patterns that lead to equipment failure. Another portion of the data is used to evaluate the model's accuracy.

Request Syntax

{ "ClientToken": "string", "DataPreProcessingConfiguration": { "TargetSamplingRate": "string" }, "DatasetName": "string", "DatasetSchema": { "InlineDataSchema": "string" }, "EvaluationDataEndTime": number, "EvaluationDataStartTime": number, "LabelsInputConfiguration": { "LabelGroupName": "string", "S3InputConfiguration": { "Bucket": "string", "Prefix": "string" } }, "ModelDiagnosticsOutputConfiguration": { "KmsKeyId": "string", "S3OutputConfiguration": { "Bucket": "string", "Prefix": "string" } }, "ModelName": "string", "OffCondition": "string", "RoleArn": "string", "ServerSideKmsKeyId": "string", "Tags": [ { "Key": "string", "Value": "string" } ], "TrainingDataEndTime": number, "TrainingDataStartTime": number }

Request Parameters

The request accepts the following data in JSON format.

ClientToken

A unique identifier for the request. If you do not set the client request token, Amazon Lookout for Equipment generates one.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Pattern: \p{ASCII}{1,256}

Required: Yes

DataPreProcessingConfiguration

The configuration is the TargetSamplingRate, which is the sampling rate of the data after post processing by Amazon Lookout for Equipment. For example, if you provide data that has been collected at a 1 second level and you want the system to resample the data at a 1 minute rate before training, the TargetSamplingRate is 1 minute.

When providing a value for the TargetSamplingRate, you must attach the prefix "PT" to the rate you want. The value for a 1 second rate is therefore PT1S, the value for a 15 minute rate is PT15M, and the value for a 1 hour rate is PT1H

Type: DataPreProcessingConfiguration object

Required: No

DatasetName

The name of the dataset for the machine learning model being created.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 200.

Pattern: ^[0-9a-zA-Z_-]{1,200}$

Required: Yes

DatasetSchema

The data schema for the machine learning model being created.

Type: DatasetSchema object

Required: No

EvaluationDataEndTime

Indicates the time reference in the dataset that should be used to end the subset of evaluation data for the machine learning model.

Type: Timestamp

Required: No

EvaluationDataStartTime

Indicates the time reference in the dataset that should be used to begin the subset of evaluation data for the machine learning model.

LabelsInputConfiguration

The input configuration for the labels being used for the machine learning model that's being created.

Type: LabelsInputConfiguration object

Required: No

ModelDiagnosticsOutputConfiguration

The Amazon S3 location where you want Amazon Lookout for Equipment to save the pointwise model diagnostics. You must also specify the RoleArn request parameter.

Type: ModelDiagnosticsOutputConfiguration object

Required: No

ModelName

The name for the machine learning model to be created.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 200.

Pattern: ^[0-9a-zA-Z_-]{1,200}$

Required: Yes

OffCondition

Indicates that the asset associated with this sensor has been shut off. As long as this condition is met, Lookout for Equipment will not use data from this asset for training, evaluation, or inference.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Required: No

RoleArn

The Amazon Resource Name (ARN) of a role with permission to access the data source being used to create the machine learning model.

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Pattern: arn:aws(-[^:]+)?:iam::[0-9]{12}:role/.+

Required: No

ServerSideKmsKeyId

Provides the identifier of the AWS KMS key used to encrypt model data by Amazon Lookout for Equipment.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Pattern: ^[A-Za-z0-9][A-Za-z0-9:_/+=,@.-]{0,2048}$

Required: No

Tags

Any tags associated with the machine learning model being created.

Type: Array of Tag objects

Array Members: Minimum number of 0 items. Maximum number of 200 items.

Required: No

TrainingDataEndTime

Indicates the time reference in the dataset that should be used to end the subset of training data for the machine learning model.

Type: Timestamp

Required: No

TrainingDataStartTime

Indicates the time reference in the dataset that should be used to begin the subset of training data for the machine learning model.

Type: Timestamp

Required: No

Response Syntax

{ "ModelArn": "string", "Status": "string" }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

ModelArn

The Amazon Resource Name (ARN) of the model being created.

Type: String
