Data Troubles in Sentence Level Confidence Estimation for Machine Translation

no code implementations26 Oct 2020 Ciprian Chelba, Junpei Zhou, Yuezhang, Li, Hideto Kazawa, Jeff Klingner, Mengmeng Niu

For an English-Spanish translation model operating at $SACC = 0. 89$ according to a non-expert annotator pool we can derive a confidence estimate that labels 0. 5-0. 6 of the $good$ translations in an "in-domain" test set with 0. 95 Precision.

Learning Energy-Based Models as Generative ConvNets via Multi-grid Modeling and Sampling

no code implementations CVPR 2018 Ruiqi Gao, Yang Lu, Junpei Zhou, Song-Chun Zhu, Ying Nian Wu

Within each iteration of our learning algorithm, for each observed training image, we generate synthesized images at multiple grids by initializing the finite-step MCMC sampling from a minimal 1 x 1 version of the training image.
