Prediction of Foodborne Diseases Pathogens: A Machine Learning Approach
Foodborne diseases, as a type of disease with a high global incidence, place a heavy burden on public health and social economy. Foodborne pathogens, as the main factor of foodborne diseases, play an important role in the treatment and prevention of foodborne diseases. However, foodborne diseases caused by different pathogens lack specificity in the clinical features, then there is a low proportion of clinically actual pathogen detection in real life.
Analyzing the data of foodborne disease cases, selecting appropriate features based on the analysis results, and using machine learning methods to classify foodborne disease pathogens, so as to predict the pathogens of foodborne diseases which have not been tested.
Extracting features such as space, time, and food exposure from the data of foodborne disease cases, analyzing the relationship between these features and the pathogens of foodborne diseases, using a variety of machine learning methods to classify the pathogens of foodborne diseases, and comparing the results to obtain the optimal pathogen prediction model with the highest accuracy.
By comparing the results of four models we used, the GBDT model obtains the highest accuracy, which is almost 69% in identifying four pathogenic bacteria including Salmonella, Norovirus, Escherichia coli, and Vibrio parahaemolyticus. And by evaluating the importance of features, we find that the time of illness, geographical longitude and latitude, diarrhea frequency and so on, play important roles in classifying the foodborne disease pathogens.
Related data analysis can reflect the distribution of some features of foodborne diseases and the relationship among the features. The classification of pathogens based on the analysis results and machine learning methods can provide beneficial support for clinical auxiliary diagnosis and treatment of foodborne diseases.
