SipSmart: Elevating Palates with Machine Learning for Wine Quality Prediction

This study explores the request of Mechanism Education (ML) techniques for predicting wine quality, aiming to enhance the understanding and precision in assessing the characteristics of different wine varieties. The dataset utilized encompasses diverse oenological parameters, such as acidity, residual sugar, alcohol content, and more. Various ML algorithms, including regression and classification models, were employed to analyze and predict wine quality based on these features. The results demonstrate the effectiveness of ML in discerning patterns and providing accurate predictions, offering valuable insights for both connoisseurs and the wine industry.Wine classification poses a formidable challenge, exacerbated by the elusive criteria that define a good-tasting wine. Certification processes currently rely on subjective sensory analysis conducted by human tasters. To address this, our study aims to predict wine quality, offering a more objective approach. We leveraged a dataset featuring various physicochemical properties of red and white variantsof Portuguese “Vinho Verde” wine, sourced from Kaggle, and utilized Google Colab for analysis. Machine learning algorithms were employed to discern ex- ceptional or subpar wine qualities. Data preprocessing involved identifying and handling missing values, while One-Hot encoding transformed categorical values into numerical ones. Feature Scaling normalized the range of independent variables. Our predictive models, including Logistic Regression, Decision Tree Classifier, Random Forest Classifier, and Extra Trees Classifier, underwent training and evaluation. Comparisons of accuracyand precision guided the selection of the most effective machine learning algorithm. This process enables us to predict wine quality on a scale of 0–10 based on a given set of features. The results contribute to the refinement of wine quality assessment, offering a more standardized and data-driven approach than traditional sensory analysis
