New extractive configuration separating azeotropic mixture in semi-batch way [PDF]

, 2006
A new variant of batch extractive distillation, the so-called inverse-fed batch extractive distillation is presented. The total amount of the entrainer is pre-loaded to the boiler, and the mixture charge to be separated is continuously fed to the column ...

Extract then Distill: Efficient and Effective Task-Agnostic BERT Distillation [PDF]

, 2021
Task-agnostic knowledge distillation, a teacher-student framework, has been proved effective for BERT compression. Although achieving promising results on NLP tasks, it requires enormous computational resources. In this paper, we propose Extract Then Distill (ETD), a generic and flexible strategy to reuse the teacher's parameters for efficient and ...
