Query: E-LANG: Energy-Based Joint Inferencing of Super and Swift Language
  Models   Building huge and highly capable language models has been a trend in the past
years. Despite their great performance, they incur high computational cost. A
common solution is to apply model compression or choose light-weight
architectures, which often need a separate fixed-size model for each desirable
computational budget, and may lose performance in case of heavy compression.
This paper proposes an effective dynamic inference approach, called E-LANG,
which distributes the inference between large accurate Super-models and
light-weight Swift models. To this end, a decision making module routes the
inputs to Super or Swift models based on the energy characteristics of the
representations in the latent space. This method is easily adoptable and
architecture agnostic. As such, it can be applied to black-box pre-trained
models without a need for architectural manipulations, reassembling of modules,
or re-training. Unlike existing methods that are only applicable to
encoder-only backbones and classification tasks, our method also works for
encoder-decoder structures and sequence-to-sequence tasks such as translation.
The E-LANG performance is verified through a set of experiments with T5 and
BERT backbones on GLUE, SuperGLUE, and WMT. In particular, we outperform T5-11B
with an average computations speed-up of 3.3$\times$ on GLUE and 2.9$\times$ on
SuperGLUE. We also achieve BERT-based SOTA on GLUE with 3.2$\times$ less
computations. Code and demo are available in the supplementary materials.
