Query: Low-Rank Hidden State Embeddings for Viterbi Sequence Labeling   In textual information extraction and other sequence labeling tasks it is now
common to use recurrent neural networks (such as LSTM) to form rich embedded
representations of long-term input co-occurrence patterns. Representation of
output co-occurrence patterns is typically limited to a hand-designed graphical
model, such as a linear-chain CRF representing short-term Markov dependencies
among successive labels. This paper presents a method that learns embedded
representations of latent output structure in sequence data. Our model takes
the form of a finite-state machine with a large number of latent states per
label (a latent variable CRF), where the state-transition matrix is
factorized---effectively forming an embedded representation of
state-transitions capable of enforcing long-term label dependencies, while
supporting exact Viterbi inference over output labels. We demonstrate accuracy
improvements and interpretable latent structure in a synthetic but complex task
based on CoNLL named entity recognition.
