-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2011-15576 2011-11-10 16:41:56 --------------------------------------------------------------------------------
Name : openfst Product : Fedora 16 Version : 1.2.8 Release : 1.fc16 URL : http://www.openfst.org/ Summary : Weighted finite-state transducer library Description : OpenFst is a library for constructing, combining, optimizing, and searching weighted finite-state transducers (FSTs). Weighted finite-state transducers are automata where each transition has an input label, an output label, and a weight. The more familiar finite-state acceptor is represented as a transducer with each transition's input and output label equal. Finite-state acceptors are used to represent sets of strings (specifically, regular or rational sets); finite-state transducers are used to represent binary relations between pairs of strings (specifically, rational transductions). The weights can be used to represent the cost of taking a particular transition. FSTs have key applications in speech recognition and synthesis, machine translation, optical character recognition, pattern matching, string processing, machine learning, information extraction and retrieval among others. Often a weighted transducer is used to represent a probabilistic model (e.g., an n-gram model, pronunciation model). FSTs can be optimized by determinization and minimization, models can be applied to hypothesis sets (also represented as automata) or cascaded by finite-state composition, and the best results can be selected by shortest-path algorithms. -------------------------------------------------------------------------------- Update Information: Upstream notes on this release: * Added Log64Weight and Log64Arc to FST library throughout, including support throughout scripts/bins/dsos * Added delayed RandGenFst that outputs tree of paths weighted by count * Made "fstmap" handle semiring conversion by adding "to_std", "to_log" and "to_log64" as supported 'map_type' arguments * Made the destructive implementation of RmEpsilon skip over states admitting no non-epsilon incoming transition * Fixed bugs: - SymbolTable memory leak in Invert() - Added escaping of " and \ in labels in fstdraw, needed for dot to function properly - Fixed handling of final weight of start state in fstpush * Finite-state archive (FAR) utilities: added stlist format supporting writing/reading to/from standard out/in at the library-level -------------------------------------------------------------------------------- ChangeLog: * Wed Nov 9 2011 Jerry James <[email protected]> - 1.2.8-1 - New upstream version - Drop unnecessary spec file elements (%clean, etc.) * Thu Sep 8 2011 Jerry James <[email protected]> - 1.2.7-3 - Rebuild for new icu. -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
