Probability Distribution Formula for an Encoder-Softmax Language Model
A pre-trained sequence encoding model processes the input sentence 'The quick fox'. After tokenization, the input is a sequence of 3 tokens: {'The', 'quick', 'fox'}. The model then generates a numerical representation, H, which is a matrix of real-valued vectors. Based on the typical function of such a model, which statement best describes the output matrix H?
Contextual Representation Analysis
Consider a pre-trained sequence encoding model that generates a numerical representation H = {h_0, h_1, ..., h_m} for an input sequence of tokens x = {x_0, x_1, ..., x_m}. The vector h_i representing the token x_i will be the same regardless of the other tokens that appear alongside it in the input sequence.

A data scientist is working with a language model that has already been fully trained on a massive text corpus, and its internal configuration is now fixed. The scientist's goal is to take a new sentence, represented by the variable , and use this finalized model to convert it into a matrix of numerical vectors, represented by the variable . Which of the following equations correctly represents this specific operation?
The equation describes how a pre-trained model generates a numerical representation from an input sequence. Match each symbol from the equation to its correct description.
