Résumé
Some decoding policies use it to adapt sampling, but entropy is not a calibrated measure of factual confidence and does not by itself show that an answer is wrong.
Plongeur bu xóot
Standard decoding uses a fixed temperature and top-p across an entire generation, but the model's uncertainty varies wildly token to token: it is near-certain after 'New York' but uncertain at the start of a creative sentence. Entropy-based sampling measures the Shannon entropy of the next-token probability distribution (and sometimes the entropy of the attention or logit 'varentropy') and uses it to modulate decoding. Low entropy means probability mass is concentrated; high entropy means it is more spread out. Neither value establishes factual correctness. Some research prototypes use entropy or related statistics to trigger different decoding actions, such as branching or retrieval, but these are heuristics whose effects require task-specific evaluation.

Adaptive, uncertainty-aware decoding is likely to merge with reasoning and tool use: a system could use distribution statistics as one signal for choosing another decoding strategy or requesting external evidence. Entropy alone should not be presented as calibrated confidence or a truth detector; any routing policy needs validation for its task and users.

Luy échantillonnage bu sukkandiko ci entropie?
Entropy summarizes how spread out a model’s next-token probability distribution is. Some decoding policies use it to adapt sampling, but entropy is not a calibrated measure of factual confidence and does not by itself show that an answer is wrong.
What does next-token entropy measure in an entropy-aware decoder?
Shannon entropy summarizes the distribution’s spread; it is not a direct truth or correctness measurement.
What does varentropy measure in some entropy-aware decoding schemes?
Varentropy is a distribution statistic about surprise variation, not an independent factuality label.
When an entropy-aware system sees a high-entropy next-token distribution, what can it reasonably conclude?
High entropy indicates uncertainty in the next-token distribution, but does not establish the truth of a claim.
What is a practical limit of using entropy to guide generation?
Entropy-guided decoding changes token selection, but factuality and calibration require separate evaluation.
A low-entropy model answer agrees with a user’s false claim. What does the entropy value establish?
Entropy is calculated from the model distribution and is not external evidence about a factual claim.
