weekly roundup 22/5

Time flies by and so do the updates...

Additions

  • adams-timeseries: new TimeseriesAutocorrelation filter
  • added array statistic: ArrayLinearRegression computes slope/intercept
  • adams-weka now has a simple wizard for batch-filtering datasets
  • added overlays: LinearRegressionOverlay and LOWESSOverlay

Fixes

  • further fixes regarding locked files under Windows, reworked the text file readers in the process (used by the TextFileReader transformer)

Changes

  • Weka/MOA/Meka/Classifying/Clustering transformers now have a variable for monitoring purposes. Whenever this variable changes, the model gets reset and needs to be loaded again. Useful when using multiple models.
  • upgraded JSch library to 0.1.52 (used for ssh, scp, ...)
  • System property "adams.io.tmpdir" allows overriding of Java's default temp directory
  • added support for intercept/slope formulas in spreadsheets
  • the SimplePlot sink now allows to specify an overlay as well
  • adams-weka: the FixedClassifierErrorsPlot plugin for the Weka Explorer now allows the specifying of the meta-data attribute range and whether to overlay a "trend" (= a linear regression line derived from the data points)

Have a good weekend!
