Key result
Proposed Monte Carlo simulation model detects the degree of carbohydrate metabolism disorder from ECGs.
Why the study?
To develop a method for constructing classification models for three or more ordered classes when the initial sample only suffices to build a binary classifier recognizing the top and bottom classes.
A novel missing sample simulation modeling technique using the Monte Carlo approach enables the construction of multi-class classification models from binary classifiers, demonstrated by detecting carbohydrate metabolism disorder severity from ECGs.

Monte Carlo simulation may enable multi-class ECG classification from limited data; leaves open prospective validation before clinical adoption.
In this paper, we propose a method for constructing classification models for three or more ordered classes when the initial sample is sufficient only to construct a binary classifier capable of recognizing the top and bottom classes relative to the class order. The classification model is constructed based on the available information about the distribution of all classes in the general population and the information about the frequency of positive result occurrence in the existing binary classifier for each ordered class. This method is based on the missing sample simulation modeling technique, which uses the Monte Carlo approach. To illustrate the proposed method, we consider a model that solves the problem of detecting the degree of carbohydrate metabolism disorder (CMD) across three classes with sufficiently high quality, based on a series of electrocardiograms (ECGs) with 11 or more ECG measurements per patient.
