Statistics for AI evaluation

Probability and statistics make AI evaluation trustworthy: confidence intervals on scores, significance of differences between models, calibration of predicted probabilities and sampling designs for audits. In this field they stop small test sets and noisy metrics from being over-read.

What probability and statistics does here.

Probability and statistics provide the mathematical framework for describing uncertainty and learning from data. They underpin estimation, testing and prediction in every risk discipline. In artificial intelligence and data and compute, statistical methods quantify the likelihood and uncertainty of losses across interconnected سیستەمە. They make the evidence behind risk decisions explicit and reproducible. The canonical description is on STEM Commons.

Uncertainty on benchmark scores

Bootstrap and analytical intervals are reported with every score, and differences between models are tested before rankings are stated.

Calibration assessment

Predicted probabilities are compared with observed outcomes to check whether a model’s confidence matches its accuracy.

Audit sampling

Samples of decisions are drawn with stated designs so that error rates for subgroups can be estimated with known precision.

Statistics for AI evaluation: Catastrophe model pipeline

Catastrophe models usually have hazard, vulnerability, exposure and financial modules, and produce loss tables, تێکڕای زیانی ساڵانە, exceedance curves, PML and TVaR.

  1. 01 Hazard

    1. 01Event catalogueDataset · Model developerThe hazard module holds a large catalogue of simulated events that represents a wide range of plausible scenarios.
    2. 03Hazard moduleModel · Model developerFor each event the hazard module gives the local hazard intensity that the vulnerability module reads.
  2. 02 Exposure and damage

    1. 02ڕووبەڕووبوونDataset · Incident responderThe exposure module houses the portfolio data, such as location-specific information.
    2. 04Vulnerability moduleModel · Model developerThe vulnerability module quantifies the expected damage to the exposures from an event.
  3. 03 Financial

    1. 05Financial moduleModel · Incident responderThe financial module calculates losses from all event scenarios. Ground-up, gross and net losses differ as shown below.
    2. 06Event loss tableDataset · Incident responderAn event loss table lists each event with its annual occurrence probability and its loss for the portfolio.
    3. 07Year loss tableDataset · Incident responderSome models also sample simulated years from event losses. This outline does not describe their format.
  4. 04 Metrics

    1. 08Exceedance probability curvesModel · Incident responderThe occurrence curve gives the chance that the largest loss in a year exceeds an amount. The aggregate curve does so for the sum of losses.
    2. 09AAL, PML and TVaRModel · Incident responderAverage annual loss sums event probability times loss. PML is one point on the occurrence curve.
  5. 05 Use of results

    1. 10Use of resultsDecision · Incident responderThe tail metrics are used when considering a portfolio’s exposure and the level of catastrophe reinsurance an insurer requires.

Outline of an external standard or method, from its public sources. It describes what the framework says, not a record of any run. It does not show that Nexus or any partner performs, certifies or approves a step. A gate is a step of the method, never a Nexus approval.

How results are checked.

Results are checked through diagnostics, cross-validation and sensitivity to assumptions. Independent replication confirms findings.

بپشکنەHow it is done
Interval reportingEvery metric is reported with its uncertainty
Multiple comparisonsComparisons across many tasks are corrected for multiple testing
Sample size planningAudit samples are sized to detect differences of stated magnitude

Inference depends on assumptions about independence, distribution and sampling that may not hold. Small or biased samples limit reliability.
