Development of feline infectious peritonitis diagnosis system by using CatBoost algorithm.

This study employed machine learning techniques to predict the rate of feline infectious peritonitis (FIP) diagnoses, with a specific focus on mutations in the spike protein gene of the feline coronavirus (FCoV). FIP is a fatal viral disease affecting the peritoneum of cats and is primarily caused by mutations in FCoV. Its diagnosis largely relies on evaluations of various biomarkers and clinical symptoms. The current analysis of FCoV spike protein gene mutations exhibits certain limitations. To address this problem, the present study employed a large dataset-comprising information on FCoV copy numbers, spike protein mutation outcomes, and related clinical data-and used machine learning models to analyze the association between spike protein gene mutations and FIP diagnosis. Various algorithms were used to establish highly accurate predictive models, namely logistic regression, random forest, decision tree, neural network, support vector machine, gradient boosting tree, and categorical boosting (CatBoost) algorithms. The model obtained using the CatBoost algorithm was discovered to have accuracy of 0.9541. Accordingly, a highly accurate predictive model was developed to enable early diagnosis of FIP and improve the rate of survival in cats. The application of machine learning technology in this study yielded research findings that provide veterinarians with effective tools for managing and preventing FIP, a painful and deadly disease for cats. This study is a pioneering work in the systematic application of multiple machine learning models to the prediction of FIP and comparison of performance results to improve diagnostic accuracy and efficiency. This study is the first of its kind in the field of FIP.
