Encoding Process in Permuted Language Modeling
While standard pre-training tasks typically employ an encoding process where each token can attend to the entire sequence via self-attention, permuted language modeling deviates from this norm. To facilitate an autoregressive generation process within an encoder-only architecture, permuted language modeling implements its sequence prediction by applying specific attention masks on the encoder side.

Consider two different training objectives for a language model. In Objective 1, the model learns by predicting a few randomly obscured words in a sentence, using all the other visible words as context. In Objective 2, the model is given a sentence's words in a randomly shuffled order and must predict them one by one according to that shuffled sequence, only using the words that have already appeared in that sequence as context. Which of the following statements best analyzes the key advantage of Objective 2?
A language model is trained using an objective where it predicts words from an input sentence one by one, but in a randomly shuffled order. For the sentence 'The quick brown fox', the model is given the prediction order [3, 1, 4, 2], corresponding to the original word positions. Arrange the following prediction tasks in the correct sequence that the model would perform.
