“…Murphree et al applied a stacking mechanism to predict the likelihood of adverse reactions induced by blood transfusions [49]. Pernia-Espinoza et al applied stacking to predict the three key points of a comprehensive force-displacement curve for bolted joints in steel structures [50]. Stacking provides a natural and effective method of combining various (often conflicting) findings from independent research activities.…”

“…To select the best prediction model to patients' no-show in future CT appointments we applied the principle of parsimony (i.e. simpler models should be chosen over more complex ones), since the both models displayed similar performance [20]. The eight predictors of no-show to CT exam appointments selected by the penalized logistic regression model are: race, marital status, month, number of no-shows to exams and consultations in the previous year, distance, lead-time and number of exams scheduled in previous year.…”

“…In the literature on machine learning algorithms, there is an agreement that, among several accurate predictive models, the one with the least complexity should be selected. Such a model will probably be more robust for new data (Pernia-Espinoza et al, 2018). The complexity of a model can be assessed from different perspectives, including the model's internal structure (Seni and Elder, 2010), the degrees of freedom (Ye, 1998), the Vapnik-Chervonenkis dimension (Vapnik and Chervonenkis, 2015), or the number of features selected for model construction (Pernia-Espinoza et al, 2018).…”

“…It is widely accepted that feeding a model with too many features not only negatively impacts the computational time, but also compromises its generalization capability. A generalization capability of a predictive model is its ability to predict the response of unseen data (Kohavi and John, 1997;Pernia-Espinoza et al, 2018). Moreover, thanks to Electronic Health Records (EHR) data, an unprecedented source of information has become available to data science researchers, which can help them to discover new influential features (Gallego et al, 2013).…”
