Creates a new 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.

Request lenses
cmlmMLModelId :: Lens' CreateMLModel Text Source
A user-supplied ID that uniquely identifies the MLModel
.
cmlmMLModelName :: Lens' CreateMLModel (Maybe Text) Source
A user-supplied name or description of the MLModel
.
cmlmMLModelType :: Lens' CreateMLModel MLModelType Source
The category of supervised learning that this MLModel
will address. Choose
from the following types:
Choose REGRESSION
if the MLModel
will be used to predict a numeric value. Choose
BINARY
if the MLModel
result has two possible values. Choose MULTICLASS
if
the MLModel
result has a limited number of values. For more information,
see the Amazon Machine Learning Developer Guide.
cmlmParameters :: Lens' CreateMLModel (HashMap Text Text) Source
A list of the training parameters in the MLModel
. The list is implemented as
a map of key/value pairs.
The following is the current set of training parameters:
'sgd.l1RegularizationAmount' - Coefficient regularization L1 norm. It controls overfitting the data by penalizing large coefficients. This tends to drive coefficients to zero, resulting in sparse feature set. If you use this parameter, start by specifying a small value such as 1.0E-08.
The value is a double that ranges from 0 to MAX_DOUBLE. The default is not
to use L1 normalization. The parameter cannot be used when L2
is specified.
Use this parameter sparingly.
'sgd.l2RegularizationAmount' - Coefficient regularization L2 norm. It controls overfitting the data by penalizing large coefficients. This tends to drive coefficients to small, nonzero values. If you use this parameter, start by specifying a small value such as 1.0E-08.
The valuseis a double that ranges from 0 to MAX_DOUBLE. The default is not
to use L2 normalization. This cannot be used when L1
is specified. Use this
parameter sparingly.
'sgd.maxPasses' - Number of times that the training process traverses the
observations to build the MLModel
. The value is an integer that ranges from 1
to 10000. The default value is 10.
'sgd.maxMLModelSizeInBytes' - Maximum allowed size of the model. Depending on the input data, the size of the model might affect its performance.
The value is an integer that ranges from 100000 to 2147483648. The default value is 33554432.
cmlmRecipe :: Lens' CreateMLModel (Maybe Text) Source
The data recipe for creating MLModel
. You must specify either the recipe or
its URI. If you don’t specify a recipe or its URI, Amazon ML creates a
default.
cmlmRecipeUri :: Lens' CreateMLModel (Maybe Text) Source
The Amazon Simple Storage Service (Amazon S3) location and file name that
contains the MLModel
recipe. You must specify either the recipe or its URI.
If you don’t specify a recipe or its URI, Amazon ML creates a default.
cmlmTrainingDataSourceId :: Lens' CreateMLModel Text Source
The DataSource
that points to the training data.
Response
Response constructor
createMLModelResponse :: CreateMLModelResponse Source
CreateMLModelResponse
constructor.
The fields accessible through corresponding lenses are:
Response lenses
cmlmrMLModelId :: Lens' CreateMLModelResponse (Maybe Text) Source
A user-supplied ID that uniquely identifies the MLModel
. This value should be
identical to the value of the MLModelId
in the request.
