DESCRIPTION

Marginalize ngram model from input model file.

SYNOPSIS

ngrammarginalize [--options] [in.fst [out.fst]]

OPTIONS

--backoff_label: type = int64, default = 0

Backoff label

--check_consistency: type = bool, default = false

Check model consistency

--iterations: type = int32, default = 1

Iterations of steady state prob calculation

--max_bo_updates: type = int32, default = 10

Max iterations of backoff re-calculation

--norm_eps: type = double, default = 0.001

Normalization check epsilon

--output_each_iteration: type = bool, default = false

Output model after each iteration

--steady_state_file: type = string, default = ""

Read steady state probs from file

--help: type = bool, default = false

show usage information

--helpshort: type = bool, default = false

show brief usage information

--tmpdir: type = string, default = "/tmp"

temporary directory

--v: type = int32, default = 0

verbose level

--fst_align: type = bool, default = false

Write FST data aligned where appropriate

--fst_default_cache_gc: type = bool, default = true

Enable garbage collection of cache

--fst_default_cache_gc_limit: type = int64, default = 1048576

Cache byte size that triggers garbage collection

--fst_read_mode: type = string, default = "read"

Default file reading mode for mappable files

--fst_verify_properties: type = bool, default = false

Verify fst properties queried by TestProperties

--fst_weight_parentheses: type = string, default = ""

Characters enclosing the first weight of a printed composite weight (e.g. pair weight, tuple weight and derived classes) to ensure proper I/O of nested composite weights; must have size 0 (none) or 2 (open and close parenthesis)

--fst_weight_separator: type = string, default = ","

Character separator between printed composite weights; must be a single character

--save_relabel_ipairs: type = string, default = ""

Save input relabel pairs to file

--save_relabel_opairs: type = string, default = ""

Save output relabel pairs to file

--end_symbol: type = string, default = "</s>"

Class label for sentence start

--start_symbol: type = string, default = "<s>"

Class label for sentence start

--fst_compat_symbols: type = bool, default = true

Require symbol tables to match when appropriate

--fst_field_separator: type = string, default = " "

Set of characters used as a separator between printed fields

--fst_error_fatal: type = bool, default = true

FST errors are fatal; o.w. return objects flagged as bad:

e.g., FSTs - kError prop. true, FST weights - not a Member()

--ngram_error_fatal: type = bool, default = true

NGram errors are fatal; o.w. return objects flagged as bad:

e.g., NGramModel::Error() returns true.
