Applying Different Resampling Strategies In Random Forest Algorithm To
Predict Lumpy Skin Disease

Lumpy Skin Disease, Machine Learning, Oversampling, Random Forest, Random Undersampling

The spread of Lumpy Skin Disease (LSD) that infects livestock is increasingly widespread in various parts of the world. Early
detection of the disease’s spread is necessary so that the economic losses caused by LSD are not higher. The use of machine
learning algorithms to predict the presence of a disease has been carried out, including in the field of animal health. The study
aims to predict the presence of LSD in an area by utilizing the LSD dataset obtained from Mendeley Data. The number of
lumpy infected cases is so low that it creates imbalanced data, posing a challenge in training machine learning models.
Handling the unbalanced data is performed by sampling technique using the Random Under-sampling technique and Synthetic
Minority Oversampling Technique (SMOTE). The Random Forest classification model was trained on sample data to predict
cases of lumpy infection. The Random Forest classifier performs very well on both under-sampling and oversampling data.
Measurement of performance metrics shows that SMOTE has a superior score of 1-2% compared to the use of Random
Undersampling. Furthermore, Re-call rate, which is the metric we want to maximize in identifying lumpy cases, is superior
when using SMOTE and has slightly better precision than Random Undersampling. This research only focuses on how to
balance unbalanced data classes so that the optimization of the model has not been implemented, which creates opportunities
for further research in the future
