Résumé

They affect diversity and candidate selection, while a predictable selection is not a guarantee that the generated claim or code is correct.

Plongeur bu xóot

A language model produces a score, called a logit, for each candidate token. Softmax converts these scores into probabilities, and a sampling procedure selects the next token. For positive temperature T, dividing logits by T changes the relative probability distribution before sampling. Values below one sharpen differences; values above one flatten them. If two logits differ by six, then division by temperature two gives a difference of three. That calculation describes the scores, not the truth of either candidate. Greedy decoding selects a highest-scoring token instead of sampling. It should be treated as a decoding rule rather than implemented by literally dividing logits by zero. A very small positive temperature concentrates probability but still differs conceptually from disabling sampling. Candidate filters offer another control. Top-k keeps a specified number of highest-probability tokens. Top-p, also called nucleus sampling, sorts candidates by probability and keeps the smallest leading set whose cumulative probability reaches or exceeds the chosen threshold. For probabilities 0.55, 0.30, 0.10, and 0.05 with top-p 0.80, the first two candidates are sufficient because they sum to 0.85. Their total need not equal the threshold exactly. These choices can influence diversity and repeatability, but no filter proves that an output is factual, safe, or syntactically valid. Generation behavior also depends on implementation and the rest of the decoding configuration, so record the actual settings when comparing results.

Sampling research examines how candidate filters and adaptive settings affect the quality and diversity of generated text. Evaluate settings for the actual task instead of assuming that one temperature always maximizes correctness. Comparisons should report the model, decoding mode, filters, and relevant constraints. For structured output, validation of the produced structure remains useful regardless of how predictable the token choices are. Generation controls shape selection; evidence checking and application validation establish whether the selected output is suitable.

What is Temperature and Sampling?

Temperature and sampling settings control how a generator selects tokens from model scores. They affect diversity and candidate selection, while a predictable selection is not a guarantee that the generated claim or code is correct.

What determines the candidate set in top-p sampling, compared with top-k?

The nucleus can exceed the cutoff slightly because whole tokens are retained.

For a structured-data task, what does choosing more predictable token selection fail to establish?

Predictability concerns selection behavior, while correctness and structural validity still need checks.

How does greedy decoding choose the next token?

Greedy decoding is a selection rule. Small positive temperature is not mathematically identical to division by zero.
