Example of Causal Language Modeling
In causal language modeling, tokens are sequentially generated following their natural text order, without any initial source-side context. For example, to generate a sequence autonomously, the model produces the output tokens one by one: The kitten is chasing the ball .. The superscripts indicate the strict left-to-right autoregressive generation order on the target side.

Schematic of Probability Calculation in Causal Language Modeling
An auto-regressive language model is designed to calculate the probability of a sequence of tokens. A key characteristic of this model is that the probability of any given token is conditioned only on the tokens that appeared before it. Given the sequence
token_A, token_B, token_C, token_D, which expression correctly represents the calculation for the probability oftoken_C?A researcher designs a language model with a specific objective: to fill in a blank word in a sentence. For example, given the input 'The quick brown ___ jumps over the lazy dog', the model must predict 'fox'. To do this, the model's architecture allows it to consider the context from both the left ('The quick brown') and the right ('jumps over the lazy dog') simultaneously when making its prediction for the blank word. Which statement accurately classifies this model?
