Adds one or more tags to an object, up to a limit of 10.
Each tag consists of a key
and an optional value. If you add a tag using a key that is already associated
with the ML object,
AddTags
updates the tag's value.
Generates predictions for a group of observations.
The observations to process exist in one or more data files referenced
by a DataSource
. This operation creates a new BatchPrediction
, and uses an
MLModel
and the data
files referenced by the 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.
Creates a DataSource
object from an Amazon Relational Database Service (Amazon RDS).
A 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 the COMPLETED
or PENDING
state can
be used only 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.
Creates a DataSource
from a database hosted on an Amazon Redshift cluster.
A
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
states can be
used to perform only CreateMLModel
, CreateEvaluation
, or
CreateBatchPrediction
operations.
If Amazon ML can't 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 be contained in the database hosted on an Amazon
Redshift cluster
and should be specified by a SelectSqlQuery
query. Amazon ML executes an
Unload
command in Amazon Redshift to transfer the result set of
the SelectSqlQuery
query to S3StagingLocation
.
After the DataSource
has been created, it's ready for use in evaluations and
batch predictions. If you plan to use the DataSource
to train an
MLModel
, the DataSource
also requires a recipe. A recipe
describes how each input variable will be used in training an MLModel
. Will
the variable be included or excluded from training? Will the variable be
manipulated;
for example, will it be combined with another variable or will it be split apart
into
word combinations? The recipe provides answers to these questions.
You can't change an existing datasource, but you can copy and modify the
settings from an
existing Amazon Redshift datasource to create a new datasource. To do so, call
GetDataSource
for an existing datasource and copy the values to a
CreateDataSource
call. Change the settings that you want to change and
make sure that all required fields have the appropriate values.
Creates a DataSource
object.
A 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
has been created and is ready for use, Amazon ML sets the
Status
parameter to COMPLETED
. DataSource
in
the COMPLETED
or PENDING
state can be used to perform only
CreateMLModel
, CreateEvaluation
or
CreateBatchPrediction
operations.
If Amazon ML can't 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) location, 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
also needs a recipe. A recipe
describes how each input variable will be used in training an MLModel
. Will
the variable be included or excluded from training? Will the variable be
manipulated;
for example, will it be combined with another variable or will it be split apart
into
word combinations? The recipe provides answers to these questions.
Creates a new Evaluation
of an MLModel
.
An MLModel
is evaluated on a set of observations associated to a DataSource
.
Like a DataSource
for an MLModel
, the DataSource
for an Evaluation
contains values for the
Target Variable
. The Evaluation
compares the predicted result for each
observation to the actual outcome and provides a
summary so that you know how effective the MLModel
functions on the test
data. Evaluation generates a relevant performance metric, such as BinaryAUC,
RegressionRMSE or MulticlassAvgFScore based on the corresponding MLModelType
:
BINARY
, REGRESSION
or 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.
Creates a new MLModel
using the DataSource
and the recipe as
information sources.
An MLModel
is nearly immutable. Users can update only 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
has been created and ready is for use, Amazon ML sets the
status to COMPLETED
.
You can use the GetMLModel
operation to check the 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.
Creates a real-time endpoint for the MLModel
.
The endpoint contains the URI of the MLModel
; that is, the location to send
real-time prediction requests for the specified MLModel
.
Assigns the DELETED status to a BatchPrediction
, rendering it unusable.
After using the DeleteBatchPrediction
operation, you can use the
GetBatchPrediction
operation to verify that the status of the BatchPrediction
changed to DELETED.
Caution: The result of the DeleteBatchPrediction
operation is
irreversible.
Assigns the DELETED status to a DataSource
, rendering it unusable.
After using the DeleteDataSource
operation, you can use the GetDataSource
operation to verify that the status of the DataSource
changed to DELETED.
Caution: The results of the DeleteDataSource
operation are irreversible.
Assigns the DELETED
status to an Evaluation
, rendering it unusable.
After invoking the DeleteEvaluation
operation, you can use the
GetEvaluation
operation to verify that the status of the Evaluation
changed
to DELETED
.
Caution: The results of the DeleteEvaluation
operation are irreversible.
Assigns the DELETED
status to an MLModel
, rendering it unusable.
After using the DeleteMLModel
operation, you can use the
GetMLModel
operation to verify that the status of the MLModel
changed to
DELETED.
