	// used to create the Datasource. If you do not include percentBegin and

	// * 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

	//
	//     * 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

	// {"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

	// A JSON string that represents the splitting and rearrangement processing to be

	// 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", "strategyParams": {"randomSeed":"RANDOMSEED"}}} Datasource
