This study focuses on the development of a machine
learning–based approach for classifying the severity of malaria, with
particular attention to cerebral malaria. The dataset was compiled from
healthcare records and included both clinical symptoms such as seizures,
altered mental state, headache, vomiting, and focal neurological deficits and
indicators reflecting household burden, including financial strain and
caregiver stress. The data were carefully prepared and divided into training
and testing sets to ensure a reliable evaluation of the model’s performance. A
Random Forest classifier was employed to distinguish between cerebral and
non-cerebral malaria cases. By leveraging multiple decision trees, the model
was trained to recognize patterns within the data and accurately predict the
severity of the condition based on the observed features. The training process
involved optimizing the model to improve its predictive capability across
different symptom combinations and contextual factors. The results demonstrated
strong performance, with the model achieving an accuracy of 0.97. Additional
evaluation metrics further supported its effectiveness, with macro-average
precision, recall, and F1 scores of 0.94, 0.91, and 0.92 respectively. Analysis
of the dataset showed that 87.2% of cases were classified as non-cerebral
malaria, while 12.8% were identified as cerebral malaria, reflecting known
patterns in malaria-endemic regions. Importantly, symptoms such as seizures,
altered mental status, and focal neurological deficits were found to be key
indicators of severe malaria. Beyond clinical implications, the study also
highlights the broader impact of the disease, particularly the financial and
emotional burden placed on affected households. Overall, the findings suggest
that machine learning techniques, especially Random Forest models, can serve as
valuable tools in supporting more accurate diagnosis and improved management of
malaria.
