Systems and methods are provided for segmenting time-series data stored in data segments containing one or more data records. A combined segment error measure is determined based on a proposed combination of two candidate segments. An error cost to merge the two candidate segments is determined based on a difference between the combined segment error measure and a segment error measure of one of the segments. The two candidate segments are combined when the error cost to merge meets a merge threshold to generate a combined segment.

Computer-implemented systems and methods for flexible definition of time intervals

Computer-implemented systems and methods to process time-series data. As an example, a system and method can use a first data store to store time series data, and a second data store to store definitions of events. A dummy variable is generated when data from an event's definition is applied to time series data.
