Tsfel

=============
- Changes
- Replaced the ``Histogram`` feature with ``Histogram mode`` (`167 <https://github.com/fraunhoferportugal/tsfel/pull/167>`_)

- Improvements
- The ``correlated_features`` method now supports returning a filtered feature vector (`163 <https://github.com/fraunhoferportugal/tsfel/pull/163>`_)

- Documentation
- Set up a Slack community invite (`164 <https://github.com/fraunhoferportugal/tsfel/issues/164>`_)
- Enhanced documentation for ``the time_series_feature_extraction`` and ``get_features_by_domain functions``
- Updated the main example notebook on Human Activity Recognition (`159 <https://github.com/fraunhoferportugal/tsfel/issues/159>`_)

=============
- New Features
- Added a new Datasets module with convenient methods to load single-problem datasets (`156 <https://github.com/fraunhoferportugal/tsfel/pull/156>`_)
- Improved the ``get_features_by_domain`` method, allowing easier selection of multiple feature domain combinations

- Improvements
- Significantly reduced the computational time for the LPCC feature (`156 <https://github.com/fraunhoferportugal/tsfel/pull/153>`_)
- Resolved deprecation issues with SciPy Wavelets by switching to PyWavelets for features that rely on wavelets (`147 <https://github.com/fraunhoferportugal/tsfel/pull/147>`_)
- Renamed the ``fft_mean_coefficient`` feature to ``spectrogram_mean_coefficient`` for descriptive correctness (`145 <https://github.com/fraunhoferportugal/tsfel/pull/145>`_)

- Bugfixes
- Fixed a bug causing a circular import issue (`154 <https://github.com/fraunhoferportugal/tsfel/pull/154>`_)
- Fixed a ResourceWarning when loading the feature configuration file (`152 <https://github.com/fraunhoferportugal/tsfel/pull/152>`_)
- Removed the use of ``eval`` (`150 <https://github.com/fraunhoferportugal/tsfel/pull/150>`_)

- Documentation
- Major documentation updates, including detailed explanations of the expected input and output data formats

=============
- New features
- Implemented the Lempel-Ziv-Complexity in the temporal domain (`146 <https://github.com/fraunhoferportugal/tsfel/pull/146>`_)
- Added the fractal domain with the following features (`144 <https://github.com/fraunhoferportugal/tsfel/pull/144>`_):
- Detrended fluctuation analysis (DFA)
- Higuchi fractal dimension
- Hurst exponent
- Maximum fractal length
- Multiscale entropy (MSE)
- Petrosian fractal dimension

- Changes
- Changed the ``autocorrelation`` logic. It now measures the first lag below (1/e) from the ACF (`142 <https://github.com/fraunhoferportugal/tsfel/issues/142>`_).

=============
- Changes
- Feature ``total energy`` changed name to ``average power``
- Features ``peak to peak``, ``absolute energy`` and ``entropy`` are now classified as statistical

- Bugfixes
- Fixed a bug on numpy bool usage (`133 <https://github.com/fraunhoferportugal/tsfel/issues/133>`_)
- Fixed a bug on features' header names

- Improvements
- Correlated features are now computed using absolute value
- Unit tests improvements
- Refactoring of some code sections and overall improved stability\

=============
- Bugfixes
- Fixed a bug on scipy function median_absolute_deviation to median_abs_deviation (`128 <https://github.com/fraunhoferportugal/tsfel/pull/128>`_)
- Fixed on pandas function df.append to pd.concat (`120 <https://github.com/fraunhoferportugal/tsfel/pull/120>`_)

=============
- Bugfixes
- Fixed a bug on the progress bar not being displayed if the signal is passed already divided into windows (`49 <https://github.com/fraunhoferportugal/tsfel/issues/49>`_)
- Fixed a bug on the ``distance`` feature (`54 <https://github.com/fraunhoferportugal/tsfel/issues/54>`_)
- Fixed a bug raising zero division in the ECDF slope feature (`57 <https://github.com/fraunhoferportugal/tsfel/pull/57>`_)
- Fixed a bug when adding customised features using the JSON
- Fixed a bug on LPC was returning inconsistent values (`58 <https://github.com/fraunhoferportugal/tsfel/pull/58>`_)
- Fixed a bug on normalised autocorrelation (`64 <https://github.com/fraunhoferportugal/tsfel/pull/64>`_)

- Improvements
- Refactoring of some code sections and overall improved stability
- The documentation has been improved and a FAQ section was created
- The ``window_splitter`` parameter is now deprecated. If the user selected a ``window_size`` it is assumed that the signal must be divided into windows.
- Unit tests improvements

- New features
- Added to return the size of the feature vector from the configuration dictionary (`50 <https://github.com/fraunhoferportugal/tsfel/issues/50>`_)
