README

This is the vowpal wabbit fast online learning code.  It is Copyright
(c) 2009 Yahoo! Inc, and released for use under the BSD (revised) open
source license.

You can download the latest version from here:

https://github.com/JohnLangford/vowpal_wabbit/archives/master

Alternatively, the very latest version is available here:

git clone git://github.com/JohnLangford/vowpal_wabbit.git

You should be able to build it on posix systems with:
make
(make test)
make install

If 'make' fails, you are probably missing the dependency on boost program options.  Intall it and try again.

Be sure to read the wiki: https://github.com/JohnLangford/vowpal_wabbit/wiki
for the tutorial, command line options, etc.  

The 'cluster' directory has it's own documentation for cluster
parallel use, and the examples at the end of test/Runtests give some
example flags.
Something went wrong with that request. Please try again.
