Flexibility of Masked Language Modeling for Encoder-Decoder Training
The Masked Language Modeling (MLM) framework offers significant flexibility for training encoder-decoder models. Different training objectives can be created by adjusting various parameters, such as the percentage of tokens that are masked and the maximum length of the text spans that are replaced by a mask token. This adaptability allows the training to range from a BERT-style objective with partial masking to a full language modeling task where the entire sequence is generated.

BART Model's Use of Diverse Input Corruption Methods
An encoder-decoder model is being trained using the following example:
- Input to Encoder: "The scientist carefully [MASK] the solution into the beaker."
- Target Output for Decoder: "The scientist carefully poured the solution into the beaker."

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During a self-supervised pre-training process, a model is given an input sequence where one word has been replaced by a special symbol, for example: 'The quick brown [MASK] jumps over the lazy dog.'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?

Example of Full Sequence Generation via 100% Masking
A research team is pre-training two separate encoder-decoder models using different variations of a masked language modeling objective.
- Model A is trained by masking 15% of the input tokens, with each mask covering only a single token. The model's objective is to predict the original token for each masked position.
- Model B is trained by masking 50% of the input tokens, with masks covering contiguous spans of up to 10 tokens. The model's objective is to predict the entire original text span.
Which of the following statements most accurately analyzes the likely capabilities these two models will develop based on their pre-training objectives?
