name: crf-chain1-constrained version: 0.6.0 synopsis: First-order, constrained, linear-chain conditional random fields description: The library provides efficient implementation of the first-order, linear-chain conditional random fields (CRFs) with position-wise constraints imposed over label values. . It is strongly related to the simpler library where constraints are not taken into account and all features which are not included in the CRF model are considered to have probability of 0. Here, on the other hand, such features do not influence the overall probability of the (sentence, labels) pair - they are assigned the default potential of 0. . Efficient algorithm for determining marginal probabilities of individual labels is provided. The tagging is performed with respect to marginal probabilities. -- The argmax algorithm (finding -- the most probable label sequence satisfying the given constraints) -- is less efficient, since we cannot use the sparse -- forward-backward recursions optimization. license: BSD3 license-file: LICENSE cabal-version: >= 1.6 copyright: Copyright (c) 2012-2018 Jakub Waszczuk, IPI PAN author: Jakub Waszczuk maintainer: waszczuk.kuba@gmail.com stability: experimental category: Math homepage: https://github.com/kawu/crf-chain1-constrained build-type: Simple extra-source-files: changelog library hs-source-dirs: src build-depends: base >= 4 && < 5 , containers >= 0.4 && < 0.6 , vector >= 0.10 && < 0.13 , array >= 0.4 && < 0.6 , random >= 1.0 && < 1.2 , parallel >= 3.2 && < 3.3 , logfloat >= 0.12.1 && < 0.14 , monad-codec >= 0.2 && < 0.3 , binary >= 0.5 && < 0.9 , vector-binary >= 0.1 && < 0.2 , data-lens >= 2.10 && < 2.12 , sgd >= 0.4.0 && < 0.5 , vector-th-unbox >= 0.2.1 && < 0.3 , pedestrian-dag >= 0.2 && < 0.3 , data-memocombinators >= 0.5 && < 0.6 exposed-modules: Data.CRF.Chain1.Constrained , Data.CRF.Chain1.Constrained.Core , Data.CRF.Chain1.Constrained.Dataset.Internal , Data.CRF.Chain1.Constrained.Dataset.External , Data.CRF.Chain1.Constrained.Dataset.Codec , Data.CRF.Chain1.Constrained.Feature , Data.CRF.Chain1.Constrained.Feature.Present , Data.CRF.Chain1.Constrained.Feature.Hidden , Data.CRF.Chain1.Constrained.Model , Data.CRF.Chain1.Constrained.Inference , Data.CRF.Chain1.Constrained.Train , Data.CRF.Chain1.Constrained.DAG -- , Data.CRF.Chain1.Constrained.DAG.Dataset.Internal , Data.CRF.Chain1.Constrained.DAG.Dataset.External , Data.CRF.Chain1.Constrained.DAG.Dataset.Codec , Data.CRF.Chain1.Constrained.DAG.Feature , Data.CRF.Chain1.Constrained.DAG.Feature.Present , Data.CRF.Chain1.Constrained.DAG.Feature.Hidden , Data.CRF.Chain1.Constrained.DAG.Inference , Data.CRF.Chain1.Constrained.DAG.Probs , Data.CRF.Chain1.Constrained.DAG.Train other-modules: Data.CRF.Chain1.Constrained.DP , Data.CRF.Chain1.Constrained.Util , Data.CRF.Chain1.Constrained.Intersect ghc-options: -Wall -O2 source-repository head type: git location: git://github.com/kawu/crf-chain1-constrained.git
