Question 18

+3 marksOne correct option

You are performing Beam Search with K=2 to generate a sequence.

Step 1: The model predicts probabilities for the first word:

text
    "A": 0.5


    "The": 0.4


    "It": 0.1

Step 2: You expand the K=2 hypotheses ("A" and "The").

Given "A", P(next word): {"dog": 0.6, "cat": 0.3, ...}

Given "The", P(next word): {"dog": 0.5, "cat": 0.4, ...}

After Step 2, what are the sequences (beams) that you will keep for Step 3?

  1. A
  2. B
