AI-MaxEntropy
view release on metacpan or search on metacpan
the concept 'feature'
0.11 Sat Feb 16 17:27:00 2008
- Optimize the XS code, now the the function 'learn' should run
at least twice faster than 0.10 version
- New functions in AI::MaxEntropy::Util, which allows the client
program manipulate samples more flexibly
- Replace Test::Differences with is_deeply in Test::More
0.10 Wed Feb 13 16:56:00 2008
- rewrite the log likelihood evaluation and smoothing by C, now
the ME learner should run more than 10 times faster than the
previous version
- add a new module AI::MaxEntropy::Util, which provides some
utilities for doing experiments with ME learners
- AI::MaxEntropy::see now accepts attribute-value style samples
- include Algorithm::Diff in the distribution for testing
0.02 Thu Feb 7 11:26:00 2008
- some tiny corrections :-P
