public CreateAutoPredictorResult createAutoPredictor(CreateAutoPredictorRequest request)
AmazonForecast
Creates an Amazon Forecast predictor.
Amazon Forecast creates predictors with AutoPredictor, which involves applying the optimal combination of algorithms to each time series in your datasets. You can use CreateAutoPredictor to create new predictors or upgrade/retrain existing predictors.
Creating new predictors
The following parameters are required when creating a new predictor:
PredictorName
- A unique name for the predictor.
DatasetGroupArn
- The ARN of the dataset group used to train the predictor.
ForecastFrequency
- The granularity of your forecasts (hourly, daily, weekly, etc).
ForecastHorizon
- The number of time-steps that the model predicts. The forecast horizon is also
called the prediction length.
When creating a new predictor, do not specify a value for ReferencePredictorArn
.
Upgrading and retraining predictors
The following parameters are required when retraining or upgrading a predictor:
PredictorName
- A unique name for the predictor.
ReferencePredictorArn
- The ARN of the predictor to retrain or upgrade.
When upgrading or retraining a predictor, only specify values for the ReferencePredictorArn
and
PredictorName
.
createAutoPredictor
in interface AmazonForecast
public CreateDatasetResult createDataset(CreateDatasetRequest request)
AmazonForecast
Creates an Amazon Forecast dataset. The information about the dataset that you provide helps Forecast understand how to consume the data for model training. This includes the following:
DataFrequency
- How frequently your historical time-series data is collected.
Domain
and DatasetType
- Each dataset has an associated dataset
domain and a type within the domain. Amazon Forecast provides a list of predefined domains and types within each
domain. For each unique dataset domain and type within the domain, Amazon Forecast requires your data to include
a minimum set of predefined fields.
Schema
- A schema specifies the fields in the dataset, including the field name and data
type.
After creating a dataset, you import your training data into it and add the dataset to a dataset group. You use the dataset group to create a predictor. For more information, see Importing datasets.
To get a list of all your datasets, use the ListDatasets operation.
For example Forecast datasets, see the Amazon Forecast Sample GitHub repository.
The Status
of a dataset must be ACTIVE
before you can import training data. Use the DescribeDataset operation to
get the status.
createDataset
in interface AmazonForecast
public CreateDatasetGroupResult createDatasetGroup(CreateDatasetGroupRequest request)
AmazonForecast
Creates a dataset group, which holds a collection of related datasets. You can add datasets to the dataset group when you create the dataset group, or later by using the UpdateDatasetGroup operation.
After creating a dataset group and adding datasets, you use the dataset group when you create a predictor. For more information, see Dataset groups.
To get a list of all your datasets groups, use the ListDatasetGroups operation.
The Status
of a dataset group must be ACTIVE
before you can use the dataset group to
create a predictor. To get the status, use the DescribeDatasetGroup
operation.
createDatasetGroup
in interface AmazonForecast
public CreateDatasetImportJobResult createDatasetImportJob(CreateDatasetImportJobRequest request)
AmazonForecast
Imports your training data to an Amazon Forecast dataset. You provide the location of your training data in an Amazon Simple Storage Service (Amazon S3) bucket and the Amazon Resource Name (ARN) of the dataset that you want to import the data to.
You must specify a DataSource object that includes an Identity and Access Management (IAM) role that Amazon Forecast can assume to access the data, as Amazon Forecast makes a copy of your data and processes it in an internal Amazon Web Services system. For more information, see Set up permissions.
The training data must be in CSV or Parquet format. The delimiter must be a comma (,).
You can specify the path to a specific file, the S3 bucket, or to a folder in the S3 bucket. For the latter two cases, Amazon Forecast imports all files up to the limit of 10,000 files.
Because dataset imports are not aggregated, your most recent dataset import is the one that is used when training a predictor or generating a forecast. Make sure that your most recent dataset import contains all of the data you want to model off of, and not just the new data collected since the previous import.
To get a list of all your dataset import jobs, filtered by specified criteria, use the ListDatasetImportJobs operation.

public CreateExplainabilityResult createExplainability(CreateExplainabilityRequest request)
AmazonForecast
Explainability is only available for Forecasts and Predictors generated from an AutoPredictor (CreateAutoPredictor)
Creates an Amazon Forecast Explainability.
Explainability helps you better understand how the attributes in your datasets impact forecast. Amazon Forecast uses a metric called Impact scores to quantify the relative impact of each attribute and determine whether they increase or decrease forecast values.
To enable Forecast Explainability, your predictor must include at least one of the following: related time series, item metadata, or additional datasets like Holidays and the Weather Index.
CreateExplainability accepts either a Predictor ARN or Forecast ARN. To receive aggregated Impact scores for all time series and time points in your datasets, provide a Predictor ARN. To receive Impact scores for specific time series and time points, provide a Forecast ARN.
CreateExplainability with a Predictor ARN
You can only have one Explainability resource per predictor. If you already enabled ExplainPredictor
in CreateAutoPredictor, that predictor already has an Explainability resource.
The following parameters are required when providing a Predictor ARN:
ExplainabilityName
- A unique name for the Explainability.
ResourceArn
- The Arn of the predictor.
TimePointGranularity
- Must be set to “ALL”.
TimeSeriesGranularity
- Must be set to “ALL”.
Do not specify a value for the following parameters:
DataSource
- Only valid when TimeSeriesGranularity is “SPECIFIC”.
Schema
- Only valid when TimeSeriesGranularity is “SPECIFIC”.
StartDateTime
- Only valid when TimePointGranularity is “SPECIFIC”.
EndDateTime
- Only valid when TimePointGranularity is “SPECIFIC”.
CreateExplainability with a Forecast ARN
You can specify a maximum of 50 time series and 500 time points.
The following parameters are required when providing a Predictor ARN:
ExplainabilityName
- A unique name for the Explainability.
ResourceArn
- The Arn of the forecast.
TimePointGranularity
- Either “ALL” or “SPECIFIC”.
TimeSeriesGranularity
- Either “ALL” or “SPECIFIC”.
If you set TimeSeriesGranularity to “SPECIFIC”, you must also provide the following:
DataSource
- The S3 location of the CSV file specifying your time series.
Schema
- The Schema defines the attributes and attribute types listed in the Data Source.
If you set TimePointGranularity to “SPECIFIC”, you must also provide the following:
StartDateTime
- The first timestamp in the range of time points.
EndDateTime
- The last timestamp in the range of time points.

public CreateForecastResult createForecast(CreateForecastRequest request)
AmazonForecast
Creates a forecast for each item in the TARGET_TIME_SERIES
dataset that was used to train the
predictor. This is known as inference. To retrieve the forecast for a single item at low latency, use the
operation. To export the complete forecast into your Amazon Simple Storage Service (Amazon S3) bucket, use the
CreateForecastExportJob operation.
The range of the forecast is determined by the ForecastHorizon
value, which you specify in the
CreatePredictor request. When you query a forecast, you can request a specific date range within the
forecast.
To get a list of all your forecasts, use the ListForecasts operation.
The forecasts generated by Amazon Forecast are in the same time zone as the dataset that was used to create the predictor.
For more information, see howitworks-forecast.
The Status
of the forecast must be ACTIVE
before you can query or export the forecast.
Use the DescribeForecast operation to get the status.
By default, a forecast includes predictions for every item (item_id
) in the dataset group that was
used to train the predictor. However, you can use the TimeSeriesSelector
object to generate a
forecast on a subset of time series. Forecast creation is skipped for any time series that you specify that are
not in the input dataset. The forecast export file will not contain these time series or their forecasted values.

public CreatePredictorResult createPredictor(CreatePredictorRequest request)
AmazonForecast
This operation creates a legacy predictor that does not include all the predictor functionalities provided by Amazon Forecast. To create a predictor that is compatible with all aspects of Forecast, use CreateAutoPredictor.
Creates an Amazon Forecast predictor.
In the request, provide a dataset group and either specify an algorithm or let Amazon Forecast choose an algorithm for you using AutoML. If you specify an algorithm, you also can override algorithm-specific hyperparameters.
Amazon Forecast uses the algorithm to train a predictor using the latest version of the datasets in the specified dataset group. You can then generate a forecast using the CreateForecast operation.
To see the evaluation metrics, use the GetAccuracyMetrics operation.
You can specify a featurization configuration to fill and aggregate the data fields in the
TARGET_TIME_SERIES
dataset to improve model training. For more information, see
FeaturizationConfig.
For RELATED_TIME_SERIES datasets, CreatePredictor
verifies that the DataFrequency
specified when the dataset was created matches the ForecastFrequency
. TARGET_TIME_SERIES datasets
don't have this restriction. Amazon Forecast also verifies the delimiter and timestamp format. For more
information, see howitworks-datasets-groups.
By default, predictors are trained and evaluated at the 0.1 (P10), 0.5 (P50), and 0.9 (P90) quantiles. You can
choose custom forecast types to train and evaluate your predictor by setting the ForecastTypes
.
AutoML
If you want Amazon Forecast to evaluate each algorithm and choose the one that minimizes the
objective function
, set PerformAutoML
to true
. The
objective function
is defined as the mean of the weighted losses over the forecast types. By
default, these are the p10, p50, and p90 quantile losses. For more information, see EvaluationResult.
When AutoML is enabled, the following properties are disallowed:
AlgorithmArn
HPOConfig
PerformHPO

public CreateWhatIfAnalysisResult createWhatIfAnalysis(CreateWhatIfAnalysisRequest request)
AmazonForecast
What-if analysis is a scenario modeling technique where you make a hypothetical change to a time series and compare the forecasts generated by these changes against the baseline, unchanged time series. It is important to remember that the purpose of a what-if analysis is to understand how a forecast can change given different modifications to the baseline time series.
For example, imagine you are a clothing retailer who is considering an end of season sale to clear space for new styles. After creating a baseline forecast, you can use a what-if analysis to investigate how different sales tactics might affect your goals.
You could create a scenario where everything is given a 25% markdown, and another where everything is given a fixed dollar markdown. You could create a scenario where the sale lasts for one week and another where the sale lasts for one month. With a what-if analysis, you can compare many different scenarios against each other.
Note that a what-if analysis is meant to display what the forecasting model has learned and how it will behave in the scenarios that you are evaluating. Do not blindly use the results of the what-if analysis to make business decisions. For instance, forecasts might not be accurate for novel scenarios where there is no reference available to determine whether a forecast is good.
The TimeSeriesSelector object defines the items that you want in the what-if analysis.
