Analyzing a Model's Architecture
Consider a system designed to determine the logical relationship between two sentences. The system's first step is to compute an alignment score for every possible pair of words, one from each sentence. These scores, which represent how strongly each word from the first sentence relates to each word in the second, are then aggregated and processed by subsequent layers to produce a final classification. Based on this architectural description, explain why this system is designed to capture inter-sentence interactions directly as its initial step, rather than comparing two pre-compiled sentence summaries.

Encoding Sentences for Pairwise Tasks
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?
