Abstract: | This final degree project focuses on the application of supervised machine learning techniques, employing explainability and uncertainty quantification methods, specifically for binary classification to predict metabolic syndrome, a medical condition that increases the risk of cardiovascular disease and diabetes. The work begins with an exploratory data analysis of a dataset composed of demographic and clinical measurements from over two thousand individuals labeled with either the absence or diagnosis of metabolic syndrome. Various models, such as random forest and gradient boosting machines, are trained and evaluated, optimizing hyperparameters and decision thresholds. The selected model is a random forest, chosen not only for its good performance but also for its ability to minimize false negatives, which is crucial in clinical diagnosis. Explainability techniques (XAI), such as SHAP, LIME, and counterfactual explanations, are applied to interpret predictions and explain the model's decisions, identifying the most relevant features for diagnosing metabolic syndrome. Furthermore, uncertainty quantification is addressed using Conformal Prediction, which provides prediction intervals with coverage guarantees and calibrated probabilities. These approaches ensured transparency and reliability, essential in a medical environment regulated by frameworks such as the European Union AI Act. |
