I'm wondering if these tasks have a form of bias that decreases the performance. If the model sees only positive examples and no negatives then it is biased on the positive paths of decisions. The moment where one changes the path to be incorrect, the model can't recover from the mistake because there weren't any negative examples during pretraining. There's many words that never follow some words but the model never sees that.

Hello, number 9) doesn't say what the task is? Also, I always wondered, do those methods work universally on all languages? For example Chinese, Korean and Japanese, with different alphabets.

I've elaborated number 9. Please let me know if it's clear now.

Some of these methods do. For example, the tasks that power word vectors apply for many languages. https://fasttext.cc/docs/en/crawl-vectors.html

Masked Language Modeling has been applied to learn cross-lingual language models. Look into: https://arxiv.org/abs/1901.07291
