In this part, we will review autoencoding model alternatives that slightly modify the original BERT. These alternative re-implementations aim to get better downstream tasks by exploiting many sources: optimizing the pretraining process and the number of layers or heads, improving data quality, designing better objective functions, and so forth. The source of improvements roughly falls into two parts: better architectural design choice and pretraining control.
Many effective alternatives have been shared lately, so it is impossible to understand and explain them all here. We can take a look at some of the most cited models in the literature and the most used ones on NLP benchmarks. Let’s start with A Lite BERT (ALBERT) as a re-implementation of BERT that focuses especially on architectural design choice.
The performance of language models is considered to improve as their size gets bigger. However, training such models is...
