... between pareto vs. non-pareto points ignores the fact that 2nd-place non-pareto points may also lead to good practical solutions. A better approach may be to adopt a graded definition of Pareto optimality ... weight vector w, takes in a foreign sen- tence f and returns a translated hypothesis h. The argmax operates in vector space and our goal is to find w leading to hypotheses on the P...

... Thus, we also associate features to each Chinese token (characters or words) to reflect the likelihood of the token being part of the translation. We describe how to train a CRF model for identifying ... potentially be used to assist translators to find the most common translation for a given term, or to supplement a bilingual terminology bank (e.g., adding multilingual titl...

... it is her task to describe the path to the instruction follower, who cannot see the reference path. Our system learns to interpret these navigational direc- tions, without access to explicit linguistic ... θ T φ(s, a) most closely approximates E[R(s, a)]. To learn these weights θ we use SARSA (Sutton and Barto, 1998), an online learn- ing algorithm similar to Q-learning (Watkins a...

This paper de- scribes the development of an adaptive dialogue sys- tem that uses the feedback of users to automatically improve ... harder to detect than others, the system’s classification accuracy depends largely on the user’s barrier. To prevent classification accuracy distorting the user evaluations, we...
