Empirical Risk Minimization with Approximations of Probabilistic Grammars Shay B. Cohen Noah A. Smith 10.1184/R1/6473354.v1 https://kilthub.cmu.edu/articles/journal_contribution/Empirical_Risk_Minimization_with_Approximations_of_Probabilistic_Grammars/6473354 <p>Probabilistic grammars are generative statistical models that are useful for compositional and sequential structures. We present a framework, reminiscent of structural risk minimization, for empirical risk minimization of the parameters of a fixed probabilistic grammar using the log-loss. We derive sample complexity bounds in this framework that apply both to the supervised setting and the unsupervised setting.</p> 2010-12-01 00:00:00 Language Technologies
