v0.5.0

Improved

• Performance improvement in Visvalingam algorithm.
• Input arrays now are passed by const reference.
• Functions on C interface accepts input parameters by value instead of pointer.
• Improved error handling capabilities in JNI and C bindings.

Fixed

• Leaks when retrieving memory from device to host.
• Fixes from clang tidy static analysis.

v0.4.0

Added

• MatrixProfileLR. This version only checks occurrences of a given query either forward or backwards on the sequence.
• MatrixProfile implementation based on SCAMP method from Zach Zimmerman.
• getChains method, it is based on Eaamon Keogh's research group version.

Improved

• Error handling capabilities, our core and bindings now throw exceptions when an error occurs.
• Performance improvement in our Visvalingam method up to 3x.

Fixed

• Precision fixes on Stddev method.
• Fix in findBestNOcurrences.

Updated

• Travis base image to Ubuntu Bionic.
• khiva is published as a dynamic library from now on.

v0.3.0

Added

• mass (Mueen's Algorithm for Similarity Search) function with a proper public interface.
• findBestNOccurrences function.
• setDeviceMemoryInGB function has been added to the Library namespace. It allows to set the device memory in order to scale some hard-coded values that have been found out for a 4GB device.

Improved

• STOMP (self-join) performance has been improved by a ~54%.

Fixed

• STOMP unit tests failing for some backends.
• STOMP (self-join) doesn't crash in batched mode for long time series.

Removed

• Some internal functions in the Matrix namespace used to compute intermediate results have been removed from the public API.

v0.2.3

Fixed

• Check and retain arrays in the JNI binding

v0.2.2

Added

• Join function in the array namespace. This function joins two given arrays along the specified dimension.

v0.2.1

Fixed

v0.2.0

Added

• KMeans algorithm.
• KShape Algorithm.
• Added Ljung-Box test.
• Installation script for Windows.
• SBD distance function.
• Header checks in all header files from core library and bindings.

Changed

• Implementation improvement of stomp function and find motifs and discords functions.
• Readme and installation Guide have been improved.

Fixed

• PAA method for non divisible number of points.
• Crosscorrelation function to work with several time series.
• Conan script to work with new conan version.
• Documentation generator to work with new PIP version.
• Cmake path for windows in installation guide.

v0.1.0

Added
