問題4

How does the temperature setting in a decoding algorithm influence the probability distribution over the vocabulary?

A. Temperature has no effect on the probability distribution; it only changes the speed of decoding.

B. Decreasing temperature broadens the distribution, making less likely words more probable.

C. Increasing temperature flattens the distribution, allowing for more varied word choices.

D. Increasing temperature removes the impact of the most likely word.
