Improved machine learning performances with transfer learning to predicting need for hospitalization in arboviral infections against the small dataset

Abstract: The prediction of hospital patients and outpatients with suspected arboviral infection individuals in research-limited settings of the urban areas is defined as a challenging process for clinicians. Dengue, Chikungunya, and Zika arboviruses have gained attention in recent years because of the high prevalence in the society and financial burden of major global health systems. In this study, we proposed a machine learning algorithm based prediction model over retrospective medical records, which are named as SIS… Show more

“…AUC is an essential indicator to evaluate the performance of ML models, which could be affected by various factors. Generally, the original dataset is a decisive factor for the value of AUC, and a dataset of high quality and a larger sample size guarantees an authoritative AUC, otherwise missing values or unbalanced data may lead to a lower AUC [39,40]. Additionally, factors resulting in false negative errors also produce a lower AUC value, especially in predictive studies; for example, a shorter follow-up time means a lower probability for a model to learn positive events and thereby causes data unbalance and false negative errors [41].…”

“…Several reports have demonstrated potential arbovirus hospitalization based on various risk factors by utilizing ML algorithms ( Sippy et al., 2020 ; Ozer et al., 2021 ). Our previous study developed a severe dengue prognosis model for rapid triage using demographic information and dengue antigen/antibody rapid test results from dengue patients ( Huang S. W. et al., 2020 ); however, 75% (18 in 24 false cases) of anti-dengue antibody negative cases were incorrectly discriminated.…”

“…The datasets contain images which are usually unrelated to the transfer learning task. However, since they reuse the weights of a complex model, transfer learning models are able to achieve high accuracy with limited amounts of data [13]. This approach offers a better starting point for machine learning tasks and thus requires a shorter amount of time to train a model [14].…”
