DESCRIPTION
Definition of the public APIs exposed by Amazon Machine Learning
METHODS
CreateBatchPrediction(BatchPredictionDataSourceId => Str, BatchPredictionId => Str, MLModelId => Str, OutputUri => Str, [BatchPredictionName => Str])
Each argument is described in detail in: Paws::MachineLearning::CreateBatchPrediction
Returns: a Paws::MachineLearning::CreateBatchPredictionOutput instance
Generates predictions for a group of observations. The observations to
process exist in one or more data files referenced by a C<DataSource>.
This operation creates a new C<BatchPrediction>, and uses an C<MLModel>
and the data files referenced by the C<DataSource> as information
sources.
CreateBatchPrediction
is an asynchronous operation. In response to CreateBatchPrediction
, Amazon Machine Learning (Amazon ML) immediately returns and sets the BatchPrediction
status to PENDING
. After the BatchPrediction
completes, Amazon ML sets the status to COMPLETED
.
You can poll for status updates by using the GetBatchPrediction operation and checking the Status
parameter of the result. After the COMPLETED
status appears, the results are available in the location specified by the OutputUri
parameter.
CreateDataSourceFromRDS(DataSourceId => Str, RDSData => Paws::MachineLearning::RDSDataSpec, RoleARN => Str, [ComputeStatistics => Bool, DataSourceName => Str])
Each argument is described in detail in: Paws::MachineLearning::CreateDataSourceFromRDS
Returns: a Paws::MachineLearning::CreateDataSourceFromRDSOutput instance
Creates a C<DataSource> object from an Amazon Relational Database
Service (Amazon RDS). A C<DataSource> references data that can be used
to perform CreateMLModel, CreateEvaluation, or CreateBatchPrediction
operations.
CreateDataSourceFromRDS
is an asynchronous operation. In response to CreateDataSourceFromRDS
, Amazon Machine Learning (Amazon ML) immediately returns and sets the DataSource
status to PENDING
. After the DataSource
is created and ready for use, Amazon ML sets the Status
parameter to COMPLETED
. DataSource
in COMPLETED
or PENDING
status can only be used to perform CreateMLModel, CreateEvaluation, or CreateBatchPrediction operations.
If Amazon ML cannot accept the input source, it sets the Status
parameter to FAILED
and includes an error message in the Message
attribute of the GetDataSource operation response.
CreateDataSourceFromRedshift(DataSourceId => Str, DataSpec => Paws::MachineLearning::RedshiftDataSpec, RoleARN => Str, [ComputeStatistics => Bool, DataSourceName => Str])
Each argument is described in detail in: Paws::MachineLearning::CreateDataSourceFromRedshift
Returns: a Paws::MachineLearning::CreateDataSourceFromRedshiftOutput instance
Creates a C<DataSource> from Amazon Redshift. A C<DataSource>
references data that can be used to perform either CreateMLModel,
CreateEvaluation or CreateBatchPrediction operations.
CreateDataSourceFromRedshift
is an asynchronous operation. In response to CreateDataSourceFromRedshift
, Amazon Machine Learning (Amazon ML) immediately returns and sets the DataSource
status to PENDING
. After the DataSource
is created and ready for use, Amazon ML sets the Status
parameter to COMPLETED
. DataSource
in COMPLETED
or PENDING
status can only be used to perform CreateMLModel, CreateEvaluation, or CreateBatchPrediction operations.
If Amazon ML cannot accept the input source, it sets the Status
parameter to FAILED
and includes an error message in the Message
attribute of the GetDataSource operation response.
The observations should exist in the database hosted on an Amazon Redshift cluster and should be specified by a SelectSqlQuery
. Amazon ML executes Unload command in Amazon Redshift to transfer the result set of SelectSqlQuery
to S3StagingLocation.
After the DataSource
is created, it's ready for use in evaluations and batch predictions. If you plan to use the DataSource
to train an MLModel
, the DataSource
requires another item -- a recipe. A recipe describes the observation variables that participate in training an MLModel
. A recipe describes how each input variable will be used in training. Will the variable be included or excluded from training? Will the variable be manipulated, for example, combined with another variable or split apart into word combinations? The recipe provides answers to these questions. For more information, see the Amazon Machine Learning Developer Guide.
CreateDataSourceFromS3(DataSourceId => Str, DataSpec => Paws::MachineLearning::S3DataSpec, [ComputeStatistics => Bool, DataSourceName => Str])
Each argument is described in detail in: Paws::MachineLearning::CreateDataSourceFromS3
Returns: a Paws::MachineLearning::CreateDataSourceFromS3Output instance
Creates a C<DataSource> object. A C<DataSource> references data that
can be used to perform CreateMLModel, CreateEvaluation, or
CreateBatchPrediction operations.
CreateDataSourceFromS3
is an asynchronous operation. In response to CreateDataSourceFromS3
, Amazon Machine Learning (Amazon ML) immediately returns and sets the DataSource
status to PENDING
. After the DataSource
is created and ready for use, Amazon ML sets the Status
parameter to COMPLETED
. DataSource
in COMPLETED
or PENDING
status can only be used to perform CreateMLModel, CreateEvaluation or CreateBatchPrediction operations.
If Amazon ML cannot accept the input source, it sets the Status
parameter to FAILED
and includes an error message in the Message
attribute of the GetDataSource operation response.
The observation data used in a DataSource
should be ready to use; that is, it should have a consistent structure, and missing data values should be kept to a minimum. The observation data must reside in one or more CSV files in an Amazon Simple Storage Service (Amazon S3) bucket, along with a schema that describes the data items by name and type. The same schema must be used for all of the data files referenced by the DataSource
.
After the DataSource
has been created, it's ready to use in evaluations and batch predictions. If you plan to use the DataSource
to train an MLModel
, the DataSource
requires another item: a recipe. A recipe describes the observation variables that participate in training an MLModel
. A recipe describes how each input variable will be used in training. Will the variable be included or excluded from training? Will the variable be manipulated, for example, combined with another variable, or split apart into word combinations? The recipe provides answers to these questions. For more information, see the Amazon Machine Learning Developer Guide.
CreateEvaluation(EvaluationDataSourceId => Str, EvaluationId => Str, MLModelId => Str, [EvaluationName => Str])
Each argument is described in detail in: Paws::MachineLearning::CreateEvaluation
Returns: a Paws::MachineLearning::CreateEvaluationOutput instance
Creates a new C<Evaluation> of an C<MLModel>. An C<MLModel> is
evaluated on a set of observations associated to a C<DataSource>. Like
a C<DataSource> for an C<MLModel>, the C<DataSource> for an
C<Evaluation> contains values for the Target Variable. The
C<Evaluation> compares the predicted result for each observation to the
actual outcome and provides a summary so that you know how effective
the C<MLModel> functions on the test data. Evaluation generates a
relevant performance metric such as BinaryAUC, RegressionRMSE or
MulticlassAvgFScore based on the corresponding C<MLModelType>:
C<BINARY>, C<REGRESSION> or C<MULTICLASS>.
CreateEvaluation
is an asynchronous operation. In response to CreateEvaluation
, Amazon Machine Learning (Amazon ML) immediately returns and sets the evaluation status to PENDING
. After the Evaluation
is created and ready for use, Amazon ML sets the status to COMPLETED
.
You can use the GetEvaluation operation to check progress of the evaluation during the creation operation.
CreateMLModel(MLModelId => Str, MLModelType => Str, TrainingDataSourceId => Str, [MLModelName => Str, Parameters => Paws::MachineLearning::TrainingParameters, Recipe => Str, RecipeUri => Str])
Each argument is described in detail in: Paws::MachineLearning::CreateMLModel
Returns: a Paws::MachineLearning::CreateMLModelOutput instance
Creates a new C<MLModel> using the data files and the recipe as
information sources.
An MLModel
is nearly immutable. Users can only update the MLModelName
and the ScoreThreshold
in an MLModel
without creating a new MLModel
.
CreateMLModel
is an asynchronous operation. In response to CreateMLModel
, Amazon Machine Learning (Amazon ML) immediately returns and sets the MLModel
status to PENDING
. After the MLModel
is created and ready for use, Amazon ML sets the status to COMPLETED
.
You can use the GetMLModel operation to check progress of the MLModel
during the creation operation.
CreateMLModel requires a DataSource
with computed statistics, which can be created by setting ComputeStatistics
to true
in CreateDataSourceFromRDS, CreateDataSourceFromS3, or CreateDataSourceFromRedshift operations.
CreateRealtimeEndpoint(MLModelId => Str)
Each argument is described in detail in: Paws::MachineLearning::CreateRealtimeEndpoint
