Random Cut Forest

The Amazon SageMaker Random Cut Forest algorithm.

class sagemaker.RandomCutForest(role=None, instance_count=None, instance_type=None, num_samples_per_tree=None, num_trees=None, eval_metrics=None, **kwargs)

Bases: AmazonAlgorithmEstimatorBase

An unsupervised algorithm for detecting anomalous data points within a data set.

These are observations which diverge from otherwise well-structured or patterned data. Anomalies can manifest as unexpected spikes in time series data, breaks in periodicity, or unclassifiable data points.

An Estimator class implementing a Random Cut Forest.

Typically used for anomaly detection, this Estimator may be fit via calls to fit(). It requires Amazon Record protobuf serialized data to be stored in S3. There is an utility record_set() that can be used to upload data to S3 and creates RecordSet to be passed to the fit call.

To learn more about the Amazon protobuf Record class and how to prepare bulk data in this format, please consult AWS technical documentation: https://docs.aws.amazon.com/sagemaker/latest/dg/cdf-training.html

After this Estimator is fit, model data is stored in S3. The model may be deployed to an Amazon SageMaker Endpoint by invoking deploy(). As well as deploying an Endpoint, deploy returns a RandomCutForestPredictor object that can be used for inference calls using the trained model hosted in the SageMaker Endpoint.

RandomCutForest Estimators can be configured by setting hyperparameters. The available hyperparameters for RandomCutForest are documented below.

For further information on the AWS Random Cut Forest algorithm, please consult AWS technical documentation: https://docs.aws.amazon.com/sagemaker/latest/dg/randomcutforest.html

Parameters
  • role (str) – An AWS IAM role (either name or full ARN). The Amazon SageMaker training jobs and APIs that create Amazon SageMaker endpoints use this role to access training data and model artifacts. After the endpoint is created, the inference code might use the IAM role, if accessing AWS resource.

  • instance_count (int or PipelineVariable) – Number of Amazon EC2 instances to use for training.

  • instance_type (str or PipelineVariable) – Type of EC2 instance to use for training, for example, ‘ml.c4.xlarge’.

  • num_samples_per_tree (int) – Optional. The number of samples used to build each tree in the forest. The total number of samples drawn from the train dataset is num_trees * num_samples_per_tree.

  • num_trees (int) – Optional. The number of trees used in the forest.

  • eval_metrics (list) – Optional. JSON list of metrics types to be used for reporting the score for the model. Allowed values are “accuracy”, “precision_recall_fscore”: positive and negative precision, recall, and f1 scores. If test data is provided, the score shall be reported in terms of all requested metrics.

  • **kwargs – base class keyword argument values.

Attach to an existing training job.

Create an Estimator bound to an existing training job, each subclass is responsible to implement _prepare_init_params_from_job_description() as this method delegates the actual conversion of a training job description to the arguments that the class constructor expects. After attaching, if the training job has a Complete status, it can be deploy() ed to create a SageMaker Endpoint and return a Predictor.

If the training job is in progress, attach will block until the training job completes, but logs of the training job will not display. To see the logs content, please call logs()

Examples

>>> my_estimator.fit(wait=False)
>>> training_job_name = my_estimator.latest_training_job.name

Training data is expected to be encoded as dense or sparse vectors in the “values” feature on each Record. If the data is labeled, the label is expected to be encoded as a list of scalas in the “values” feature of the Record label.

More information on the Amazon Record format is available at: https://docs.aws.amazon.com/sagemaker/latest/dg/cdf-training.html

See record_set() to construct a RecordSet object from ndarray arrays.

Parameters

The behavior of setting these keys is as follows: * If ExperimentName is supplied but TrialName is not a Trial will be automatically created and the job’s Trial Component associated with the Trial. * If TrialName is supplied and the Trial already exists the job’s Trial Component will be associated with the Trial. * If both ExperimentName and TrialName are not supplied the trial component will be unassociated. * TrialComponentDisplayName is used for display in Studio.

  • role (str) – An AWS IAM role (either name or full ARN). The Amazon SageMaker training jobs and APIs that create Amazon SageMaker endpoints use this role to access training data and model artifacts.

class sagemaker.RandomCutForestPredictor(endpoint_name, sagemaker_session=None, serializer=<sagemaker.amazon.common.RecordSerializer object>, deserializer=<sagemaker.amazon.common.RecordDeserializer object>, component_name=None)

Bases: Predictor

Assigns an anomaly score to each of the datapoints provided.

The implementation of predict() in this Predictor requires a numpy ndarray as input. The array should contain the same number of columns as the feature-dimension of the data used to fit the model this Predictor performs inference on.

predict() returns a list of Record objects (assuming the default recordio-protobuf deserializer is used), one for each row in the input. Each row’s score is stored in the key score of the Record.label field.

Initialization for RandomCutForestPredictor class.
