NAME

CHANGES - Revision history of SenseClusters

DESCRIPTION

1.01

Released April 6, 2008 (All changes by TDP)

• Relaxed test conditions for svdpackout and install.sh to simply check if SVDPACKC is producing results.

• Removed diagnostic warning from mat2harbo.pl that gave guidelines on setting las2.h parameters. A version of las2.h is now being provided in /External with fairly large values pre-set, thus making these warnings somewhat less necessary.

• Changed the interpretation of the --negatives option below to mean that if this option is on, then any negative values in svdpackout.pl output will be set to zero. By default then, square root values are not taken, and negatives are not smoothed.

• Introduced --sqrt option for svdpackout.pl to request that values in S matrix have their square root taken before recombination. This was previously the default, but will not be any longer.

• Updated svdpackout.pl to include the following changes, provided by Richard Wicentowski in November 2006 (via senseclusters-developers list)

  • Added feature to output the component U, S, and V' matrices.

  • Added a new command-line option "--output" with three options:

    • reconstruct - reconstructs the rank-k matrix (default)

    • rowonly - same as --rowonly

    • components - output U, S, V' matrices to U.txt, S.txt, VT.txt

  • Added a new command-line option "--negatives": Allows negative values; otherwise all negative values are set to 0 (except in component output).

  • New options maintain backward compatibility

  • Updated the documentation.

  • Passes all tests (testA1-A4,B1-B2)

1.00

Released March 29, 2008 (All changes by TDP) This is a development release, meaning that "regular" users should still use 0.95, our last stable release

• Updated SYNOPSIS examples in many of the Toolkit programs to make their stand alone use more clear

• Removed dependency on Math::BigInt, Math::BigFloat, as that has been added to Algorithm::RandomMatrixGeneration as of 0.06 (which is required).

• Raised Text-NSP version requirement to 1.09, since there are a few bugs in the test cases for 1.07 and below for 64 bit architectures.

• Changed CPAN module prereqs to require modules that only require Perl 5.6 or better. This relaxes SenseClusters from requiring Perl 5.8.5 to 5.6.

0.98

Released March 25, 2008 (All changes by TDP) This is a development release, meaning that "regular" users should still use 0.95, our last stable release

• Inserted a /t directory for 'make test'. This is just a stub to be built upon.

• Modified README.Toolkit to (hopefully) include links to source code documentation while displaying all the programs in a single page. This is intended to be our replacement for the HTML pages we no longer generate.

• Modified Makefile.PL to create man pages only of core SenseClusters programs. Reduced the number of programs put into /bin as well, only including core SenseClusters programs and those needed for testing.

• Modified /Testing script completely. Removed alltests.sh subtests.sh and the many normal-op.sh and error-op.sh scripts and replaced with a single script called ALL-TESTS.sh (using same name as NSP). Historically we've had some trouble with the test scripts not running due to file permissions and path issues, so I hope this fixes that once and for all. The test*.sh files in the subdirectories of /Testing are called directly via ALL-TESTS.sh using 'csh ./testA*.sh' after the script has changed to the current directory of the test script. This does not require that the scripts be executable and path issues are minimized. This also allows us to not install altests.sh and subtests.sh in /bin (which was our solution to path problems, but that seemed a bit extreme).

• Added copyright information to .pl files in Web directory, also minimal perldoc.

• Added short labels to each of the programs in Toolkit, so that these descriptions appear in CPAN listing

• Removed HTML directory and support from /Docs, since we'll get nicely formatted documentation from CPAN. Removed /Docs, which has been replaced with /doc

• Removed samples from /Docs for regex, stoplist, and token files, since those also exist in Demos

• Added a directory /External that includes a modified form of the SVDPACKC program las2 that we use for SVD. This can be installed via a script External/install.sh that will also attempt to retrieve and install the Cluto programs scluster and vcluster.

• Moved Docs/Flows to doc/Flowcharts, depricated flowchart.fig and .pdf in favor of more recent versions

• Moved INSTALL from top level to /doc and converted into pod.

• Created doc directory which will be home of pod that is stored in top level in plain text form. /doc/update-pod.sh will be used to convert pod to plain text which should be considered read only.

• Added stubs to /lib and /t to provide basic modular framework should we decided to develop modules in future

• Moved current contents of Changes to /doc/Changelogs and then began a new file CHANGES.pod that will be used in future

0.96

Released March 22, 2008 (All modifications by TDP) This is a development release, meaning that "regular" users should still use 0.95, our last stable release

• version 0.95 uploaded to CPAN to see how indexing looked. not released on sourceforge or announced since strictly a development view.
