-
-Usage: $executable [options] <ini file>
-
- $executable [options] <ini file>
- Runs a complete PRO optimization using the ini file specified.
-
-Required:
-
- --ref-files <files>
- Dev set ref files. This option takes only a single string argument.
- To use multiple files (including file globbing), this argument should
- be quoted.
-
- --source-file <file>
- Dev set source file.
-
- --weights <file>
- Initial weights file (use empty file to start from 0)
-
-General options:
-
- --help
- Print this message and exit.
-
- --dont-accumulate
- Don't accumulate k-best lists from multiple iterations.
-
- --max-iterations <M>
- Maximum number of iterations to run. If not specified, defaults
- to $default_max_iter.
-
- --metric <method>
- Metric to optimize.
- Example values: IBM_BLEU, NIST_BLEU, Koehn_BLEU, TER, Combi
-
- --pass-suffix <S>
- If the decoder is doing multi-pass decoding, the pass suffix "2",
- "3", etc., is used to control what iteration of weights is set.
-
- --workdir <dir>
- Directory for intermediate and output files. If not specified, the
- name is derived from the ini filename. Assuming that the ini
- filename begins with the decoder name and ends with ini, the default
- name of the working directory is inferred from the middle part of
- the filename. E.g. an ini file named decoder.foo.ini would have
- a default working directory name foo.
-
-Regularization options:
-
- --reg <F>
- l2 regularization strength [default=500]. The greater this value,
- the closer to zero the weights will be.
-
-Job control options:
-
- --jobs <I>
- Number of decoder processes to run in parallel. [default=$default_jobs]
-
- --qsub
- Use qsub to run jobs in parallel (qsub must be configured in
- environment/LocalEnvironment.pm)
-
- --pmem <N>
- Amount of physical memory requested for parallel decoding jobs
- (used with qsub requests only)
