Understanding the Answer

Let's break down why this is correct

Answer

The process begins by computing attention scores that measure how much each part of the input should influence the rest. These scores are then applied to the input sequence, weighting each element accordingly. The weighted sum produces a single context vector that summarizes the relevant information. Finally, this context vector is fed into the next part of the model for tasks such as prediction or classification. For example, a language model would use the context vector to decide the next word.

Detailed Explanation

The system first calculates attention scores to see how much each part of the input matters. Other options are incorrect because This order puts the context vector right after computing scores, then applies scores after that, which is impossible; It suggests applying scores before they are calculated, which defies logic.
