The value is a double that ranges from 0
to MAX_DOUBLE
. The default is to not use L1
normalization. This parameter can't be used when L2
is specified. Use this parameter sparingly.
sgd.l2RegularizationAmount
- The 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

is stored in this location.
String dataRearrangement
A JSON string that represents the splitting and rearrangement processing to be applied to a
DataSource
. If the DataRearrangement
parameter is not provided, all of the input data
is used to create the Datasource
.
There are multiple parameters that control what data is used to create a datasource:
percentBegin
Use percentBegin
to indicate the beginning of the range of the data used to create the Datasource.
If you do not include percentBegin
and percentEnd
, Amazon ML includes all of the data
when creating the datasource.
percentEnd
Use percentEnd
to indicate the end of the range of the data used to create the Datasource. If you do
not include percentBegin
and percentEnd
, Amazon ML includes all of the data when
creating the datasource.
complement
The complement
parameter instructs Amazon ML to use the data that is not included in the range of
percentBegin
to percentEnd
to create a datasource. The complement
parameter is useful if you need to create complementary datasources for training and evaluation. To create a
complementary datasource, use the same values for percentBegin
and percentEnd
, along
with the complement
parameter.
For example, the following two datasources do not share any data, and can be used to train and evaluate a model. The first datasource has 25 percent of the data, and the second one has 75 percent of the data.
Datasource for evaluation: {"splitting":{"percentBegin":0, "percentEnd":25}}
Datasource for training: {"splitting":{"percentBegin":0, "percentEnd":25, "complement":"true"}}
strategy
To change how Amazon ML splits the data for a datasource, use the strategy
parameter.
The default value for the strategy
parameter is sequential
, meaning that Amazon ML
takes all of the data records between the percentBegin
and percentEnd
parameters for
the datasource, in the order that the records appear in the input data.
The following two DataRearrangement
lines are examples of sequentially ordered training and
evaluation datasources:
Datasource for evaluation:
{"splitting":{"percentBegin":70, "percentEnd":100, "strategy":"sequential"}}
Datasource for training:
{"splitting":{"percentBegin":70, "percentEnd":100, "strategy":"sequential", "complement":"true"}}
To randomly split the input data into the proportions indicated by the percentBegin and percentEnd parameters,
set the strategy
parameter to random
and provide a string that is used as the seed
value for the random data splitting (for example, you can use the S3 path to your data as the random seed
string). If you choose the random split strategy, Amazon ML assigns each row of data a pseudo-random number
between 0 and 100, and then selects the rows that have an assigned number between percentBegin
and
percentEnd
. Pseudo-random numbers are assigned using both the input seed string value and the byte
offset as a seed, so changing the data results in a different split. Any existing ordering is preserved. The
random splitting strategy ensures that variables in the training and evaluation data are distributed similarly.
It is useful in the cases where the input data may have an implicit sort order, which would otherwise result in
training and evaluation datasources containing non-similar data records.
The following two DataRearrangement
lines are examples of non-sequentially ordered training and
evaluation datasources:
Datasource for evaluation:
{"splitting":{"percentBegin":70, "percentEnd":100, "strategy":"random", "randomSeed"="s3://my_s3_path/bucket/file.csv"}}
Datasource for training:
{"splitting":{"percentBegin":70, "percentEnd":100, "strategy":"random", "randomSeed"="s3://my_s3_path/bucket/file.csv", "complement":"true"}}

value for the random data splitting (for example, you can use the S3 path to your data as the random seed
string). If you choose the random split strategy, Amazon ML assigns each row of data a pseudo-random number
between 0 and 100, and then selects the rows that have an assigned number between percentBegin
and
percentEnd
. Pseudo-random numbers are assigned using both the input seed string value and the byte
offset as a seed, so changing the data results in a different split. Any existing ordering is preserved. The
random splitting strategy ensures that variables in the training and evaluation data are distributed similarly.
It is useful in the cases where the input data may have an implicit sort order, which would otherwise result in
training and evaluation datasources containing non-similar data records.
The following two DataRearrangement
lines are examples of non-sequentially ordered training and
evaluation datasources:
Datasource for evaluation:
{"splitting":{"percentBegin":70, "percentEnd":100, "strategy":"random", "randomSeed"="s3://my_s3_path/bucket/file.csv"}}
Datasource for training:
{"splitting":{"percentBegin":70, "percentEnd":100, "strategy":"random", "randomSeed"="s3://my_s3_path/bucket/file.csv", "complement":"true"}}
String dataSchema
A JSON string that represents the schema for an Amazon S3 DataSource
. The DataSchema
defines the structure of the observation data in the data file(s) referenced in the DataSource
.
You must provide either the DataSchema
or the DataSchemaLocationS3
.
Define your DataSchema
as a series of key-value pairs. attributes
and
excludedVariableNames
have an array of key-value pairs for their value. Use the following format to
define your DataSchema
.
{ "version": "1.0",
"recordAnnotationFieldName": "F1",
"recordWeightFieldName": "F2",
"targetFieldName": "F3",
"dataFormat": "CSV",
"dataFileContainsHeader": true,
"attributes": [
{ "fieldName": "F1", "fieldType": "TEXT" }, { "fieldName": "F2", "fieldType": "NUMERIC" }, { "fieldName": "F3", "fieldType": "CATEGORICAL" }, { "fieldName": "F4", "fieldType": "NUMERIC" }, { "fieldName": "F5", "fieldType": "CATEGORICAL" }, { "fieldName": "F6", "fieldType": "TEXT" }, { "fieldName": "F7", "fieldType": "WEIGHTED_INT_SEQUENCE" }, { "fieldName": "F8", "fieldType": "WEIGHTED_STRING_SEQUENCE" } ],
"excludedVariableNames": [ "F6" ] }
String dataSchemaLocationS3
Describes the schema location in Amazon S3. You must provide either the DataSchema
or the
DataSchemaLocationS3
.
String key
A unique identifier for the tag. Valid characters include Unicode letters, digits, white space, _, ., /, =, +, -, %, and @.
String value
An optional string, typically used to describe or define the tag. Valid characters include Unicode letters, digits, white space, _, ., /, =, +, -, %, and @.
String batchPredictionId
The ID assigned to the BatchPrediction
during creation. This value should be identical to the value
of the BatchPredictionId
in the request.
String dataSourceId
The ID assigned to the DataSource
during creation. This value should be identical to the value of
the DataSourceID
in the request.
String evaluationId
The ID assigned to the Evaluation
during creation. This value should be identical to the value of
the Evaluation
in the request.
String mLModelId
The ID assigned to the MLModel
during creation.
String mLModelName
A user-supplied name or description of the MLModel
.
Float scoreThreshold
The ScoreThreshold
used in binary classification MLModel
that marks the boundary
between a positive prediction and a negative prediction.
Output values greater than or equal to the ScoreThreshold
receive a positive result from the
MLModel
, such as true
. Output values less than the ScoreThreshold
receive
a negative response from the MLModel
, such as false
.
String mLModelId
The ID assigned to the MLModel
during creation. This value should be identical to the value of the
MLModelID
in the request.
