fst-train - learning transducer weights

pages of fst-infl2.

fst-train is used to learn statistical weights for the transducers
transitions based on training data. Training is either unsupervised
(default) or supervised (option -b).
In supervised mode, the input contains fully disambiguated data with
the surface and the analysis form. The format restrictions are
identical to those applying for lexicon entries, i.e. all operators
other than the colon operator (:) are interpreted literally.
In unsupervised mode, the input data consists of surface strings. The
format is identical to the input format of fst-infl and fst-infl2.
The transducer weights are stored in files whose names are obtained by
appending .prob to the names of the transducer files.
No bugs are known so far.
