XLM and mBERT

We have picked two models to explain in this section: mBERT and XLM. We selected these models because they correspond to the two best multilingual types as of writing this article. mBERT is a multilingual model trained on a different corpus of various languages using MLM modeling. It can operate separately for many languages. On the other hand, XLM is trained on different corpora using MLM, CLM, and TLM language modeling, and can solve cross-lingual tasks. For instance, it can measure the similarity of the sentences in two different languages by mapping them in a common vector space, which is not possible with mBERT.

mBERT

You are familiar with the BERT autoencoder model from Chapter 3, Autoencoding Language Models, and how to train it using MLM on a specified corpus. Imagine a case where a wide and huge corpus is provided not from a single language, but from 104 languages instead. Training on such a corpus would result in a multilingual version of BERT. However...
