emd-0.2.0.0: CHANGELOG.md
Changelog
=========
Version 0.2.0.0
---------------
*October 30, 2019*
<https://github.com/mstksg/emd/releases/tag/v0.2.0.0>
* Sift condition system totally revamped, allowing for custom sift
conditions.
Version 0.1.10.0
---------------
*October 19, 2019*
<https://github.com/mstksg/emd/releases/tag/v0.1.10.0>
* Sifting condition checking system has been revamped to be more flexible.
* New sift conditions added:
* Projections based on functions:
* Energy Difference function (for Energy Difference Tracking)
* Mean envelope RMS
* For the above, we can now stop sifting based on:
* Those projections reaching a certain value
* Successive values of those projections reaching a certain squared
difference (Cauchy-inspired convergence)
* S-Number Criterion
* Add test suites
Version 0.1.9.0
---------------
*October 9, 2019*
<https://github.com/mstksg/emd/releases/tag/v0.1.9.0>
* *Breaking*: `hlMags` field in `HHT v n a` now contains `n + 1` items,
instead of `n` items. Use `V.init` to regain the original behavior.
* Added `hlInitPhase` field to `HHTLine`, to denote the initial phase that an
HHT Line starts at.
* Added `hhtResidual` field to `HHT`, to store the residual of the original
EMD.
* Add `ihht` and `ihhtEmd`, to invert Hilbert-Huang Transform and reconstruct
the original series (or the original EMD).
* Begin benchmarking `hht` and `ihht`.
Version 0.1.8.0
---------------
*October 4, 2019*
<https://github.com/mstksg/emd/releases/tag/v0.1.8.0>
* Add `meanMarginal`
* Fix `degreeOfStationarity` for divide-by-zero errors.
* Add `foldFreq` for generalized folding on `HHT`, and rewrote other
functions in terms of it.
* Drop support for GHC 8.2 and lower.
* *0.1.8.1*: Exported `marginal` again; it was unexported by mistake.
Version 0.1.7.0
---------------
*September 24, 2019*
<https://github.com/mstksg/emd/releases/tag/v0.1.7.0>
* Rewrite `hilbert` using the *fft* library, matching the matlab
implementation. This means that the library now depends on *fftw*.
Version 0.1.6.0
---------------
*September 24, 2019*
<https://github.com/mstksg/emd/releases/tag/v0.1.6.0>
* Add `hilbertPhase` to *Numeric.HHT*.
Version 0.1.5.1
---------------
*September 3, 2019*
<https://github.com/mstksg/emd/releases/tag/v0.1.5.1>
* Remove dependency on *pure-fft*, using *statistics* instead.
Version 0.1.5.0
---------------
*August 31, 2019*
<https://github.com/mstksg/emd/releases/tag/v0.1.5.0>
* Add `NFData` instance for `EMD`, `HHTLine`, and `HTT`
* Add `iemd`, inverting `emd`.
Version 0.1.4.0
---------------
*August 20, 2018*
<https://github.com/mstksg/emd/releases/tag/v0.1.4.0>
* `hhtSparseSpectrum` added to *Numeric.HHT* module, for an alternate sparser
representation of the Hilbert Spectrum.
* `hhtDenseSpectrum` also added to *Numeric.HHT*, for an alternative denser
representation.
* `expectedFrequency` added to *Numeric.HHT* module, to calculate weighted
average of frequency contributions at each step in time.
* `dominantFrequency` also added to *Numeric.HHT* to calculate strongest
frequency at each step in time.
Version 0.1.3.0
---------------
*August 15, 2018*
<https://github.com/mstksg/emd/releases/tag/v0.1.3.0>
* `Default` instance for `SiftCondition` and `EMDOpts`, as a useful
alternative to `defaultEO` and `defaultSC` for those who prefer it.
* `Binary` instances for `EMD`, `HHT`, and related data types. These are
based on `Binary` instance for `v a`, so the user must bring the orphan
instance of their choice into scope. Not sure if this is the best way to
do this.
Version 0.1.2.1
---------------
*July 27, 2018*
<https://github.com/mstksg/emd/releases/tag/v0.1.2.1>
* *BUG FIX* Fixed behavior of frequency wrapping to wrap between 0 and 1,
instead of 0.5, as claimed!
Version 0.1.2.0
---------------
*July 27, 2018*
<https://github.com/mstksg/emd/releases/tag/v0.1.2.0>
* Actually implemented the Hilbert-Huang transform
* Allowed for other border handling behaviors during EMD
* Changed default stopping conditions for sifting process
* Added clamped spline end conditions.
* Removed unsized interface
* Sifting will now throw runtime exception for singular splining matrices,
instead of treating the result as a residual. This might change in the
future.
Version 0.1.1.0
---------------
*July 25, 2018*
<https://github.com/mstksg/emd/releases/tag/v0.1.1.0>
* Unsized interface added.
Version 0.1.0.0
---------------
*July 25, 2018*
<https://github.com/mstksg/emd/releases/tag/v0.1.0.0>
* Initial release
