    • A Computational Model for the Acquisition and Use of Phonological Knowledge 

      Yip, Kenneth; Sussman, Gerald Jay (1996-03-01)
      Does knowledge of language consist of symbolic rules? How do children learn and use their linguistic knowledge? To elucidate these questions, we present a computational model that acquires phonological knowledge from a ...

    • Computing Upper and Lower Bounds on Likelihoods in Intractable Networks 

      Jaakkola, Tommi S.; Jordan, Michael I. (1996-03-01)
      We present techniques for computing upper and lower bounds on the likelihoods of partial instantiations of variables in sigmoid and noisy-OR networks. The bounds determine confidence intervals for the desired likelihoods ...

    • Mean Field Theory for Sigmoid Belief Networks 

      Saul, Lawrence K.; Jaakkola, Tommi; Jordan, Michael I. (1996-08-01)
      We develop a mean field theory for sigmoid belief networks based on ideas from statistical mechanics. Our mean field theory provides a tractable approximation to the true probability distribution in these networks; it ...
