title: Effective Exploitation of Posterior Information for Attention-Based Speech Recognition
abstract: End-to-end attention-based modeling is increasingly popular for tackling sequence-to-sequence mapping tasks. Traditional attention mechanisms utilize prior input information to derive attention, which then conditions the output. However, we believe that knowledge of posterior output information may convey some advantage when modeling attention. A recent technique proposed for machine translation called the posterior attention model (PAM) demonstrates that posterior output information can be used
