Overview
This algorithm is a technique for detecting unusual patterns that differ from common patterns in a data set, and considers individual data points as outliers when they differ significantly from surrounding data. Various machine learning algorithms can find outliers that match the algorithm's characteristics, and they learn to receive higher scores as the distance between the distribution of normal data and the distribution of abnormal data increases, and as the proportion of abnormal data decreases. The machine learning algorithm with the highest final score is selected, and the parameters optimized for it are determined.

Delivery details
Amazon SageMaker algorithm
An Amazon SageMaker algorithm is a machine learning model that requires your training data to make predictions. Use the included training algorithm to generate your unique model artifact. Then deploy the model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.
Version release notes
Required input parameters must be entered to enable model learning to prevent malfunction.

Inputs
- Summary
You need to input time series unstructured data in csv format. Specify the time and target columns in the hyperparameters. The data index must be at least 300. Below is the method for setting hyperparameters.
- time_column: indicates time column name (format: %Y-%m-%d T%H:%M:%S).
- x_column: indicates the column name for detecting.
- index_column: epresents a column name that means a separator to create different models for each group.
- Input MIME type
- text/csv
Input data descriptions
The following table describes supported input data fields for real-time inference and batch transform.
Field name | Description | Constraints | Required |
|---|---|---|---|
value | If you do not change target_column and time_column with hyperparameters, the column name as shown below is recognized as default and the existence of the column is checked in the input data.
- value: target column (single column)
- timestamp: time format data (UTC format) | Type: Continuous | Yes |
timestamp | If you do not change target_column and time_column with hyperparameters, the column name as shown below is recognized as default and the existence of the column is checked in the input data.
