Effect of Candidate Pool Size on Text Generation
A language model is tasked with completing the sentence 'The sun began to set over the...'. It uses a decoding strategy where, at each step, it considers only a fixed number ('k') of the most likely next words to choose from. Below are two outputs generated by the model using two different settings for 'k'.
Output A: '...ocean. The waves crashed on the shore. The sky turned orange.'
Output B: '...crystal spires. The air hummed with forgotten magic. The sky bled purple.'
Analyze the two outputs. Which output was likely generated using a very small value for 'k' (e.g., k=3), and which was likely generated using a much larger value (e.g., k=50)? Justify your reasoning by explaining the relationship between the size of the candidate word pool and the characteristics of the generated text.

Top-k Sampling Process
Comparison of Top-p and Top-k Sampling
A language model is generating text and has calculated the following probabilities for potential next tokens:
mat(0.45),rug(0.25),floor(0.15),table(0.10), andwindow(0.03). If the model uses a decoding strategy where it first identifies the 3 most probable tokens and then randomly samples one token from only that reduced group, which of the following statements is true?Effect of Candidate Pool Size on Text Generation
A language model is configured to generate text by first selecting a fixed number of the most probable next tokens and then sampling from only that reduced set. If the fixed number of tokens to consider is significantly decreased (e.g., from 100 to 5), what is the most likely impact on the generated text?
