Increasing model size when pretraining natural language representations often\nresults in improved performance on downstream tasks. However, at some point\nfurther model increases become harder due to GPU/TPU memory limitations and\nlonger training times. To address these problems, we present two\nparameter-reduction techniques to lower memory consumption and increase the\ntraining speed of BERT. Comprehensive empirical evidence shows that our\nproposed methods lead to models that scale much better compared to the original\nBERT. We also use a self-supervised loss that focuses on modeling\nin…
