Query: BERT2DNN: BERT Distillation with Massive Unlabeled Data for Online
  E-Commerce Search   Relevance has significant impact on user experience and business profit for
e-commerce search platform. In this work, we propose a data-driven framework
for search relevance prediction, by distilling knowledge from BERT and related
multi-layer Transformer teacher models into simple feed-forward networks with
large amount of unlabeled data. The distillation process produces a student
model that recovers more than 97\% test accuracy of teacher models on new
queries, at a serving cost that's several magnitude lower (latency 150x lower
than BERT-Base and 15x lower than the most efficient BERT variant, TinyBERT).
The applications of temperature rescaling and teacher model stacking further
boost model accuracy, without increasing the student model complexity.
  We present experimental results on both in-house e-commerce search relevance
data as well as a public data set on sentiment analysis from the GLUE
benchmark. The latter takes advantage of another related public data set of
much larger scale, while disregarding its potentially noisy labels. Embedding
analysis and case study on the in-house data further highlight the strength of
the resulting model. By making the data processing and model training source
code public, we hope the techniques presented here can help reduce energy
consumption of the state of the art Transformer models and also level the
playing field for small organizations lacking access to cutting edge machine
learning hardwares.
