- CreatedAt
-
Indicates the time and date at which the machine learning model was created.
Type: Timestamp
- 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, theTargetSamplingRate
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 PT1HType: DataPreProcessingConfiguration object
