Elastic Architecture Search for Efficient Language Models
As large pre-trained language models become increasingly critical to natural language understanding (NLU) tasks, their substantial computational and memory requirements have raised significant economic and environmental concerns. Addressing these challenges, this paper introduces the Elastic Language Model (ELM), a novel neural architecture search (NAS) method optimized for compact language models. ELM extends existing NAS approaches by introducing a flexible search space with efficient transformer blocks and dynamic modules for dimension and head number adjustment. These innovations enhance the efficiency and flexibility of the search process, which facilitates more thorough and effective exploration of model architectures. We also introduce novel knowledge distillation losses that preserve the unique characteristics of each block, in order to improve the discrimination between architectural choices during the search process. Experiments on masked language modeling and causal language modeling tasks demonstrate that models discovered by ELM significantly outperform existing methods.
Executive Impact
The Elastic Language Model (ELM) addresses critical challenges in deploying large language models by significantly improving efficiency without sacrificing performance. This breakthrough enables enterprises to leverage advanced NLP capabilities at a fraction of the traditional computational cost, accelerating innovation and expanding accessibility.
