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 ...

Extracting the Essence of Distillation [PDF]
, 2010 In this paper, we give a re-formulation of our previously defined distillation algorithm, which can automatically transform higher-order functional programs into equivalent tail-recursive programs. Our re-formulation simplifies the presentation of the transformation and hopefully makes it easier to understand.

Application of Ionic Liquids in Extractive Distillation of Ethanol – Water System
Chemical Engineering Transactions, 2015 Extractive distillation is one of the most common processes used to separate components of azeotropic mixtures. Its most distinct constrains are the tremendous energy costs required to achieve a fluid phase system.
