stream_2.0-3

stream 2.0-3 (03/11/25)

Bugfix

• We check now the parameters for DSC_BICO (m-muecke).
• deparse1 requires R 4.0.0 (reported by m-muecke).

Changes

• Refactoring by m-muecke

stream_2.0-2

stream 2.0-2 (04/19/24)

New Features

• Added DSF_FeatureSelection.

Bugfix

• Fixed exports for get_macroclusters.DSC_DStream, get_macroweights.DSC_DStream
  and recluster.DSC
• predict for DSC now honors the formula in the DSC.

Changes

• Improved manual pages
• proxy is now imported and not attached globally.

stream 2.0-1 (02/28/23)

New Features

• Added DST_SlidingWindow to call functions on a sliding window.
• Added DSClassifier_SlidingWindow, DSRegressor_SlidingWindow, and DSC_SlidingWindow.
• Added get_model() for DST.
• DSF can now be used with DST interface (update(), etc.).
• DSD now also provides update().

Changes

• transitioned from C++11 to C++17.
• update() gained parameter return and lost assignment for DSC.
• DST_WriteStream and write_stream now flush after the write.
• DST_WriteStream gained close_stream().
• Added tests for DSD. get_points with n = 0 and n = -1 produce now consistent results.
• write_stream has now no default for n and accepts n = -1.

stream_2.0-0

stream 2.0-0 (09/01/22)

New Features

• We now support %>% and defining pipelines with the new class DST_Runner.
• New base class DSF for data stream filters with implementations for
  DSF_Downsample, DSF_Convolve, DSF_Func, DSF_dplyr
• New DST_Multi to run multiple tasks on a stream.
• New DSD_NULL
• New DSOutlier: DSOutlier_DBSTREAM, DSOutlier_DStream
• DSD_ReadCSV gained parameter col.names
• Added DSD_ReadStream as an alias for DSD_ReadCSV.
• Added DST_WriteStream to write streams using update().
• Added DSD_Mixture to combine streams.
• update() now returns information like cluster assignments as a data.frame.
• DSC implementations now have a formula argument to decide what variables should be used for
  clustering.
• DSD_ReadDB has now close_stream().
• DSD_Memory, DSD_ReadDB and DSD_ReadStream have now a parameter called outofpoints to handle
  the situation that get_points requests more points than available.

Changes

• stream now implements a standard predict function (get_assignment() is now deprecated).
• class information and extra information are now stored as columns starting with '.'
  instead of as attributes. See get_points().
• DSD_ScaleStream is now DSF_Scale and DSD_ScaleStream is deprecated.
• DSO is now called DSAggregate.
• The NAMESPACE is now managed using roxygen.
• evaluate is now a generic.
• noise and outliers are now the same concept. DS_Gaussian can make sure that noise points are
  separated from clusters.
• evaluate() is now called evaluate_static() and evaluate_cluster is evaluate_stream(), both are now generics.
• plot for DSC now automatically finds micro and macro-clusters to plot.

stream_1.5-1

Changes

• Removed registry in favor of using R Studio auto-complete.
• Outlier detectors are now in class DSOutlier class.
• We use now roxygen2 for man pages.
• Abstract classes now have constructors.

Bug Fixes

• Fixed typo in BIRCH interface: treshold -> threshold (by dinarior)

stream_1.5.0

New Features

• DSC implementations are now registered using DSC_registry.

Bug Fixes

• Fixed get_assignment.DSC_TwoStage when new data is available (reported by
  ozlempoyraz).

stream_1.4-0: Single phase + outlier clusterer support and other additions (#14)

New Features

• Added additional features to the DSD_Gaussians, now capable of using Mahalanobis distance and
  generating outliers.
• Updated evaluation procedure, now capable of performing external indices calculation using callbacks
• Added support for single-pass clusterers and outlier detectors
• Added outlier correctness assessment indices

stream_1.3-2

stream 1.3-2 (05/04/20)

Bug Fixes

• DBSTREAM: Fixed array index bug (reported by MatthiasCarnein)
• BIRCH: Fixed C++ this pointer problem.

stream_1.3.1

New Features

• Added DSC_evoStream and DSC_EA. Code by Matthias Carnein.

Changes

• Package animation is now only suggested since it requires package magick
  which may need the imagemagick++ libraries installed.

stream_1.3-0

• Added DSC_BIRCH. Code and Interface by Dennis Assenmacher and Matthias Carnein.
• Added DSC_BICO. Code by Hendrik Fichtenberger, Marc Gille, Melanie Schmidt,
  Chris Schwiegelshohn, Christian Sohler and Interface provided by Matthias
  Carnein and Dennis Assenmacher.
• DSD_ReadCSV: Fixed bug with streams that have no class/cluster label
  (reported by Matthias Carnein).
• animate_cluster: noise now accepts "class" or "exclude" ("ignore" is deprecated).

stream_1.2-4

• Use dbFetch in DSD_ReadDB (new version of RSQLite).
• Register native C routines.
