incerto.llm.SequenceProbability

class incerto.llm.SequenceProbability

Bases: object

Joint probability of the entire sequence.

Computed as the product of individual token probabilities. Lower values indicate higher uncertainty.

Methods

__init__()
compute(logits, token_ids[, dim])	Compute sequence probability.

static compute(logits, token_ids, dim=-1)

Compute sequence probability.

Parameters:

• logits (Tensor) – Token logits of shape (batch, seq_len, vocab_size)

• token_ids (Tensor) – Generated token IDs of shape (batch, seq_len)

• dim (int) – Dimension to compute softmax over (default: -1)

Return type:

Tensor

Returns:

Sequence probabilities of shape (batch,)
