Validity and efficiency of the conformal CUSUM procedure
Vladimir Vovk, Ilia Nouretdinov, Alex Gammerman
In this paper we study the validity and efficiency of a conformal version of the CUSUM procedure for change detection both experimentally and theoretically.
Conformal testing: binary case with Markov alternatives
Vladimir Vovk, Ilia Nouretdinov, Alex Gammerman
We continue study of conformal testing in binary model situations. In this note we consider Markov alternatives to the null hypothesis of exchangeability. We propose two new classe…
Retrain or not retrain: Conformal test martingales for change-point detection
Vladimir Vovk, Ivan Petej, Ilia Nouretdinov +3
We argue for supplementing the process of training a prediction algorithm by setting up a scheme for detecting the moment when the distribution of the data changes and the algorith…
Conformal e-testing
Vladimir Vovk, Ilia Nouretdinov, Alex Gammerman
There is a useful counterpart of conformal prediction for e-values, called conformal e-prediction. Conformal prediction can serve as basis for testing the assumption of exchangeabi…
Computationally efficient versions of conformal predictive distributions
Vladimir Vovk, Ivan Petej, Ilia Nouretdinov +2
Conformal predictive systems are a recent modification of conformal predictors that output, in regression problems, probability distributions for labels of test observations rather…
Multi-level conformal clustering: A distribution-free technique for clustering and anomaly detection
Ilia Nouretdinov, James Gammerman, Matteo Fontana +1
In this work we present a clustering technique called \textit{multi-level conformal clustering (MLCC)}. The technique is hierarchical in nature because it can be performed at multi…
