AUTOCLASS C VERSION 2.5 NOTES
======================================================================
======================================================================
Documentation:
------------------------------
1. autoclass-c/doc/reports-c.text -
Minor typographical changes. Added new report generation
parameter: order_attributes_by_influence_p. Its default
value is true. The file extension of the influence values
report has been changed from ".influ-text-1" to ".influ-o-text-1"
when order_attributes_by_influence_p = true, and to
".influ-no-text-1" when order_attributes_by_influence_p = false.
2. autoclass-c/doc/interpretation-c.text -
Minor changes to the text.
3. autoclass-c/sample/imports-85c.influ-o-text-1
Influence values report has been significantly revised and
reformatted.
4. autoclass-c/doc/search-c.text -
Corrected definition of fixed_j.
Programming:
------------------------------
1. autoclass-c/prog/globals.c -
Update "G_ac_version" to 2.5.
2. autoclass-c/prog/intf-reports.c, utils.c -
Formatting change to "format_real_attribute" for multiple
multivariate attribute groups.
Remove covariance matrix output and reformat the correlation
matrix output to fixed decimal point notation.
For the influence values report, sort real valued attributes
of the same model group by the first significance value, if
that group is multi_normal_cn.
For discrete attributes: relabel the headers "Prob", rather than
"Mean"; and correct the instance value significance computation
to be "local_prob * log( local_prob / global_prob)".
3. autoclass-c/prog/autoclass.h -
Add #ifndef for MAXPATHLEN.
4. autoclass-c/prog/io-results.c -
In "validate_data_pathname", "validate_results_pathname", &
"make_and_validate_pathname", only do fclose, if fopen returns
non-NULL.
5. autoclass-c/prog/search-control-2.c -
Add "pad" argument to "print_search_try".
6. autoclass-c/prog/intf-extensions.c -
Formatting change to "get_models_source_info".
7. autoclass-c/load-ac,
autoclass-c/prog/autoclass.make.sun.gcc, autoclass.make.sun.acc,
autoclass.make.sun.cc, autoclass.make.sgi -
(remove autoclass.make.sun)
Add SunOS/Solaris C compiler support.
8. autoclass-c/prog/io-results.c, io-read-model.c, io-read-data.c,
utils.c, intf-reports.c, getparmas.c -
Cast return values of "strlen" to int.
9. autoclass-c/prog/model-transforms.c -
In "generate_singleton_transform", correct segmentation fault
which occurs when more than 25 type = real, subtype = scalar
attributes are defined in the ".hd2" & ".model" files.
10. autoclass-c/prog/struct-data.c, io-results.c, io-results-bin.c -
Properly initialize att_info array when it exceeds preallocated
size.
11. autoclass-c/load-ac,
autoclass-c/prog/autoclass.make.linux.gcc, autoclass.make.sun.*,
autoclass.make.sgi, fcntlcom-ac.h -
Thanks to Andrew Lewycky <plewycky@oise.on.ca>, added mods for
port to Linux version 1.2.10, GCC version 2.5.8, libc version
4.6.25.
12. autoclass-c/prog/model-single-multitnomial.c -
In "sm_params_influence_fn", add check for out-of-bounds
arguments to the log function to prevent "log domain" errors.
