NAME
hfst-reweight - =Reweight transducer weights simply
SYNOPSIS
hfst-reweight [OPTIONS...] [INFILE]
DESCRIPTION
Reweight transducer weights simply
Common options:
-h, --help
Print help message
-V, --version
Print version info
-v, --verbose
Print verbosely while processing
-q, --quiet
Only print fatal erros and requested output
-s, --silent
Alias of --quiet
Input/Output options:
-i, --input=INFILE
Read input transducer from INFILE
-o, --output=OUTFILE
Write output transducer to OUTFILE
Reweighting options:
-a, --addition=AVAL
add AVAL to matching weights
-b, --multiplier=BVAL
multiply matching weights by BVAL
-F, --function=FNAME
operate matching weights by FNAME
-l, --lower-bound=LVAL
match weights greater than LVAL
-u, --upper-bound=UVAL
match weights less than UVAL
-I, --input-symbol=ISYM
match arcs with input symbol ISYM
-O, --output-symbol=OSYM
match arcs with output symbol OSYM
-S, --symbol=SYM
match arcs havins symbol SYM
-e, --end-states-only
match end states only, no arcs
-A, --arcs-only
match arcs only, no end states
-T, --tsv-file=TFILE
read reweighting rules from TFILE
If OUTFILE or INFILE is missing or -, standard streams will be used. Format of result
depends on format of INFILE If AVAL, BVAL or FNAME are omitted, they default to neutral
elements of addition, multiplication or identity function. If LVAL or UVAL are omitted,
they default to minimum and maximum values of the weight structure. If ISYM, OSYM or SYM
are omitted, they default to a value that matches all arcs.
Float values are parsed with strtod(3) and integers strtoul(3). The functions allowed for
FNAME are <cmath> float functions with parameter count of 1 and a matching return value:
abs, acos, asin, ... sqrt, tan, tanh
The precedence of operands follows the formula BVAL * FNAME(w) + AVAL. The formula is
applied iff: ((LVAL <= w) && (w <= UVAL)), where w is weight of arc, and (ISYM == i) &&
(OSYM == o) && ((SYM == i) || (SYM == o)) ^^ (end state && -e).
TFILE should contain lines with tab-separated pairs of SYM and AVAL or BVAL. AVAL values
must be preceded by a + character, BVAL should be given as plain digits. Comment lines
starting with # and empty lines are ignored.
Weights are by default modified for all arcs and end states, unless option
--end-states-only or --arcs-only is used.
