Encoding Sentences for Pairwise Tasks
In natural language processing tasks that involve comparing or analyzing two sentences, each sentence is first converted into a numerical representation or vector. For example, one sentence can be encoded as a vector and the second sentence as a vector , allowing models to process and compare them mathematically.

A system is being designed to determine the semantic relationship between two sentences, Sentence A and Sentence B. Two different processing methods are proposed:
Method 1: The system processes Sentence A and Sentence B independently, converting each into its own fixed-size numerical summary. These two summaries are then compared to determine the final relationship.
Method 2: The system processes both sentences together, using a mechanism to calculate how each word in Sentence A relates to every word in Sentence B. This rich set of cross-sentence relationships is then combined to determine the final output.
Which method is fundamentally structured to capture and aggregate the granular, word-by-word interactions between the two sentences as a core part of its process?

Analyzing an Initial Model Step for Sentence Comparison
An AI developer is building a model to determine if two sentences are paraphrases of each other. The model must be able to perform a mathematical comparison of the sentences' meanings. What is the essential initial step to prepare the two sentences for this type of model?
