Original Sequence for Masking and Deletion Examples
The sentence 'The puppies are frolicking outside the house .' serves as a base or original sequence for illustrating text corruption techniques. From this sentence, specific tokens can be selected to be either replaced with a [MASK] token (masking) or removed entirely (deletion), creating a noisy version for model training.

Training Objective of the Standard BERT Model
During a self-supervised pre-training process, a model is given an input sequence where one word has been replaced by a special symbol, for example: 'The quick brown [MASK] jumps over the lazy dog.' The model's objective is to predict the original word, 'fox'. Which of the following is the direct input used by the final output layer to make this specific prediction?

Consider the following two text sequences:
Sequence A: 'The puppies are frolicking outside the house .' Sequence B: 'The puppies are [MASK] outside [MASK] house .'
In the context of preparing data to train a language model, what is the primary purpose of creating Sequence B from Sequence A?
In the context of preparing data for language model training, an original sentence is often intentionally corrupted. Match each type of text sequence with its corresponding example.
