-Usage: $executable [options] <ini file>
-
- $executable [options]
- Runs a complete MERT optimization. Required options are --weights,
- --devset, and --config.
-
-Options:
-
- --config <file> [-c <file>]
- The decoder configuration file.
-
- --devset <file> [-d <file>]
- The source *and* references for the development set.
-
- --weights <file> [-w <file>]
- A file specifying initial feature weights. The format is
- FeatureName_1 value1
- FeatureName_2 value2
- **All and only the weights listed in <file> will be optimized!**
-
- --metric <name>
- Metric to optimize.
- Example values: IBM_BLEU, NIST_BLEU, Koehn_BLEU, TER, Combi
-
- --iterations <M>
- Maximum number of iterations to run. If not specified, defaults
- to 10.
-
- --pass-suffix <S>
- If the decoder is doing multi-pass decoding, the pass suffix "2",
- "3", etc., is used to control what iteration of weights is set.
-
- --rand-directions <num>
- MERT will attempt to optimize along all of the principle directions,
- set this parameter to explore other directions. Defaults to 5.
-
- --output-dir <dir>
- Directory for intermediate and output files.
-
- --help
- Print this message and exit.
-
-Job control options:
-
- --jobs <I>
- Number of decoder processes to run in parallel. [default=$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)
