deltakit.core.decoding_graphs.EdgeRecord.from_loglikelihood

classmethod EdgeRecord.from_loglikelihood(weight: float) → EdgeRecord

Create a EdgeRecord from a loglikelihood weight rather than a p_err.

Parameters:

weight (float) – Edge weight as a loglikelihood, defined as w=ln((1-p)/p) where w is the weight, p is error probability and ln is the natural log.

Return type:

EdgeRecord
