Improving the objective function in minimum error rate training [PDF]

open access: yes, 2009
In Minimum Error Rate Training (MERT), the parameters of an SMT system are tuned on a certain evaluation metric to improve translation quality. In this paper, we present empirical results in which parameters tuned on one metric (e.g.

Dealing with Integer-valued Variables in Bayesian Optimization with Gaussian Processes [PDF]

open access: yes, 2017
Bayesian optimization (BO) methods are useful for optimizing functions that are expensive to evaluate, lack an analytical expression and whose evaluations can be contaminated by noise. These methods rely on a probabilistic model of the objective function,
