How should a fixed audit budget be split between gold-labelled and noisy audits?
research/ambient-auditbudget
How to split a fixed audit budget between gold and noisy audits when gold costs 3 to 30 times more: all-noisy is worst or near-worst in all 12 cells, 25% on gold with a joint EM fit is within 0.0009 of the best, and all-gold loses when gold is expensive (stylised)
What it found
Extending the stylised gold-audit model with a price: a gold audit costs 3, 10 or 30 noisy audits, with budgets of 200 and 1000. Spending everything on noisy audits read as truth is the worst or near-worst split in all 12 cells (0.387–0.388 at label accuracy 0.7). There is no single best share, but 25% of the budget on gold, fitted jointly with the noisy audits by EM, is within 0.0009 of the best in every cell and 50% within 0.0016. When gold is expensive, all-gold is worse (0.3843 at B = 200, cost 30). Stylised: uniform-error matrices, one auditor accuracy, round-number utilities.

- Can an assistant learn its urgency label’s reliability from two noisy auditors, and what does a wrongly assumed auditor accuracy cost?Can the assistant learn its urgency label's reliability from two noisy auditors with no accuracy known (Dawid-Skene), and what does a wrong assumed auditor accuracy cost: over-trusting the auditor loses 31% of a 0.9 label's gain, and Dawid-Skene reaches within 0.0005 of the oracle at n = 1000 (stylised)
- What does Dawid–Skene do when the two auditors share their errors?What does Dawid-Skene do when the two auditors share their errors: it over-trusts them (auditor accuracy read as 0.909 for a true 0.8 at half shared) and loses part of its edge over trusting one auditor, falling to equal it when the second auditor is a copy, never below it (stylised)
- What if the two auditors only share errors on hard messages, and can a hardness-aware EM fix Dawid–Skene?What if the auditors only share errors on hard messages: Dawid-Skene's cost is much smaller than with copying (policy utility 0.4060 vs 0.4066 at 30% hard messages), reaching the naive estimator only in an extreme cell, and a hardness-aware EM recovers the classifier but cannot identify the hard share (stylised)
- Does a third auditor identify the hard-message share, and does it help plain Dawid–Skene?Does a third auditor identify the hard-message share: yes at the population level (P(hard) 0.300 from informed starts), only loosely at n=1000 (sd 0.07), and in the extreme cell plain Dawid-Skene with three auditors falls below the naive estimator (0.3912 vs 0.3992) while the hardness-aware EM does not (stylised)
- Does a likelihood-ranked multi-start make the hardness-aware EM robust to a poor start?Does a likelihood-ranked multi-start make hardness-aware Dawid-Skene robust to a poor start: at the population level yes (P(hard) 0.300, vs 0.500 and a lower likelihood from a poor single start), at finite n it matches one informed start, and where hardness is absent the hard share is not identified (stylised)
- How many starts does the likelihood-ranked multi-start need, and are grid starts better than random ones?How many starts does a likelihood-ranked multi-start need, and are grid starts better than random ones: one start is nearly enough with strong hardness or n = 1000, 4 starts reach the best optimum in most cells, more help only in the weak-hardness and null cells, and policy utility barely moves (stylised)
