Generating synthetic time series datasets having change points

A method comprising:

• receiving a user input comprising a command to generate a synthetic time series dataset;
• generating data points for a plurality of consecutive time slots of the synthetic time series dataset using functions, wherein a first plurality of data points is generated using a first function from a first plurality of available functions and a second plurality of data points is generated using a second function from a second plurality of available functions, and wherein one of the first function or the second function is harmonic and another one of the first function or the second function denotes trend;
• modifying one or more parameters of the second function to generate a third function, wherein the third function is a harmonic function or a trend function that is different from the second function;
• generating a change point for the synthetic time series dataset by replacing, for a subset of the plurality of consecutive time slots, corresponding data points of the second plurality of data points with a corresponding third plurality of data points generated using the third function;
• and
• generating the synthetic time series dataset comprising the change point by combining (i) the first plurality of data points and the second plurality of data points for corresponding time slots of the plurality of consecutive time slots and (ii) the first plurality of data points and the corresponding third plurality of data points for the subset of the plurality of consecutive time slots.

One or more non-transitory, computer-readable media storing instructions that, when executed by one or more processors, cause operations comprising:

• receiving a user input comprising a command to generate a synthetic time series dataset;
• generating, for a plurality of consecutive time slots of the synthetic time series dataset, a first plurality of data points using a first function from a first plurality of available functions and a second plurality of data points using a second function from a second plurality of available functions, wherein the second function is different from the first function;
• modifying one or more parameters of the second function to generate a third function, wherein the third function is different from the second function;
• generating a change point for the synthetic time series dataset by replacing, for a subset of the plurality of consecutive time slots, corresponding data points of the second plurality of data points with a corresponding third plurality of data points generated using the third function;
• and
• generating the synthetic time series dataset comprising the change point by combining (i) the first plurality of data points and the second plurality of data points for the plurality of consecutive time slots and (ii) the first plurality of data points and the corresponding third plurality of data points for the subset of the plurality of consecutive time slots.
