Timeseries Features DSLedit

Defines how time series data must be aggregated into features for learning and inference.

Features define how to aggregate numerical data from a measurement A measurement defines an object type in the data source:

  • For Elasticsearch data source, the measurement is the object _type field value
  • For InfluxDB data source, the measurement is the series measurement name

The list below defines the aggregation operators can be used to define features. These values can be extracted by using numeric fields in the data source documents.

Note

This version does not support feature generation by a provided script, nor extracting features from categories ie, non numeric fields.

The operators that are supported consist of: count, min, max, sum, avg, sum_of_squares, variance, and std_deviation.

Note

This version supports the following additional operators with InfluxDB: derivative, integral, spread, mode, 5percentile, 10percentile, 90percentile, 95percentile, stddev
