    Accelerated training of conditional random fields with stochastic gradient methods
    Download  people.cs.ubc.ca
    We apply Stochastic Meta-Descent (SMD), a stochastic gradient optimization method with gain vector adaptation, to the training of Conditional Random Fields (CRFs). On several larg...
