Changes in version 1.2-3 (08/07/16)

  • fixed saveDSC for DBStream.
  • fixed handling of data with d=1 (reported by Ilana Lichtenstein).
  • plot now automatically determines if the data supports a class attribute.

Changes in version 1.2-2 (10/28/15)

  • evaluate now reports noise information.

Changes in version 1.2-1 (09/08/15)

  • fixed problem with failing test under Windows.

Changes in version 1.2-0 (09/06/15)

  • generic and methods for description() added to exact descriptions from
    DSD, DSC and DSO objects.
  • write_stream() gained parameter append and now throws an error if it
    would overwrite a file.
  • DSC objects can now be saved and loaded using saveDSC and readDSC.
  • we use now DBSCAN from package dbscan.
  • DSC_DBSTREAM gained parameter metric and now also supports
    Manhattan and Maximum norm.
  • DSC_DBSTREAM gained parameter assignments and function
    get_cluster_assignments() to retrieve the MC assignment of the
    clustered data points.
  • cleaned up interface for animate_cluster() and animate_data().
  • DSD_ReadCSV was completely rewritten to be more reliable. Lost argument d
    which is now figured out automatically.
  • write_stream has now an argument called header (former name was col.names)
    to be consistent with DSD_ReadCSV.

Changes in version 1.1-5 (07/02/15)

  • NAMESPACE now imports non-standard packages correctly.
  • DSC_DBSTREAM uses now Cm instead of noise.
  • fixed iterator bug for DSC_DBSTREAM.
  • evaluate gains argument noise to control if noise is ignored

Changes in version 1.1-4 (05/24/15)

  • evaluate checks if DSD has cluster labels for external
    evaluation measures.
  • DSD_mlbenchmarkGenerator now shuffles data points.
  • DSC_ReadCSV gains arguments skip and header.
  • DSC_DStream: was reimplemented in C++ (Rcpp),
    number of grids N can now be fixed by the user.
  • DSC_tNN was renamed DSC_DBSTREAM. Uses now SOM-style micro-cluster update
    and was reimplemented in C++ (Rcpp).

Changes in version 1.1-1 (01/15/15)

  • DSC_DStream: fixed bug with removing too many sporadic grids
  • DSD_ReadCSV now uses readLine so it can read properly from URLs
  • updated vignette

Changes in version 1.1-0 (12/18/14)

  • update now directly dispatches
  • DSC_Memory replaces DSD_Wrapper
  • DSD_ReadCSV replaces DSD_ReadStream. Improved handling of blocking and
    end of stream.
  • added DSD_ReadDB (DBI interface)
  • get_points can now produce cluster and class information

Changes in version 1.0-3 (07/14/14)

  • Fixed precision and recall calculation
  • Added DSC_TwoStage

Changes in version 1.0-2 (06/16/14)

  • Warning for reclusterers removed.
  • plot can now show micro-cluster assignment areas using assignment=TRUE

Changes in version 1.0-1 (06/12/14)

  • Improved documentation
  • Improved DSD_MG
  • plot gained a dim argument to plot only selected dimensions
  • get_assignment gained a threshold argument
  • DSC_Window added
  • DSC_Sample gained a biased argument for biased sampling
  • DSC_Wrapper can now wrap matrix-like objects (e.g., from package ff and
    bigmemory)

Changes in version 1.0-0 (5/24/14)

  • added D-Stream (with attraction)
  • improved support for creating animations
  • tnn: new decay models, tNN without shared density now reclusters
    using density reachability
  • plot gained the type "both" that plots micro and macro-clusters
  • DSC_Hierarchical and DSC_Kmeans gained min_weight to filter low weight
    micro-clusters before reclustering
  • removed default radius, etc. for most clustering algorithms
  • Added DSD_MG for simulating streams with concept drift
  • moved MOA related code to streamMOA
  • suspended DSC_BIRCH because of memory issues
  • reset_stream gained a pos argument

Changes in version 0.2-0 (2/21/14)

  • major restructuring

Initial version 0.1-1 (8/16/13)
