CHANGELOG

This changelog is maintained starting from version 0.4.0.

0.4.0

  • Complete redesign of the backend using abstract types, structs, and function overloading, replacing the previous function-based implementation.
  • The input type of the distribution function has been changed to StateSpaceSet for time series, improving interoperability with DynamicalSystems.jl.
  • The output type of the distributions function has been changed to Probabilities, improving interoperability with ComplexityMeasures.jl
  • Added a new GPU backend based on KernelAbstractions.jl.
  • Implemented operations for computing microstate permutations.

BREAKING CHANGES

Version 0.4.0 is not backward compatible with v0.3.1. The backend has been redesigned from a function-based architecture to one based on abstract types, structs, and method overloading.

The overall usage of the distribution function remains similar, but its configuration options have changed. Significant changes were also introduced in RQA computation: the package now uses a unified measure interface and the QuantificationMeasure type instead of the standalone functions used previously.

Key changes:

  • The functions rentropy, rrate, determinism, laminarity, and disorder have been replaced by the generic measure function together with the corresponding subtypes of QuantificationMeasure.
  • The function find_parameters has been replaced by optimize using the Threshold type.
  • The function prepare has been removed, since this functionality is now provided by DynamicalSystems.jl.
  • The distribution function is no longer configured via keyword arguments for the microstate shape and recurrence function. These are now specified using the types MicrostateShape and RecurrenceExpression. The sampling mode and sampling ratio remain configurable via keyword arguments, but SamplingMode is now a type rather than a symbol, and the keyword sampling_mode has been renamed to sampling.
  • The inputs of distributions and histogram for time series are no longer Vector or Matrix. They must now be provided as a StateSpaceSet.
  • The sampling modes :columnwise and :triangleup have been temporarily removed.
  • The microstate shapes :square and :line were unified into the unique type Rect.
