Since managing enormous datasets in the real world is difficult, it is necessary to minimize the size of the data set, so that the accuracy of the original dataset is no longer impacted. In this study, the categorization of the white wine dataset is examined using a number of machine learning techniques, including Naive Bayes (NB), Support Vector Machine (SVM), Random Forest (RF), K Nearest Neighbour (KNN), and Logistic Regression (LR). Additionally, we utilized the stated dataset using the defined methodologies and presented the Sampling from Clusters (SC) approach. The white wine dataset is first clustered using our suggested method SC, and then 95% of the data from each cluster is removed and combined to create a standard dataset for classification process. For 90%, 85%, and 80% of the data, the same procedure is repeated. On the other hand, we used a random sampling (RS) technique to work with 95% of the data from the dataset in question, and we compared the results with SC using evaluation metrics like accuracy, precision, recall, F1-score, Receiver Operating Characteristic (ROC), Area under the Curve (AUC), binomial confidence interval (CI), and MSE. With 90%, 85%, and 80% of the datasets, the same procedure is repeated. According to statistics, confidence intervals CI become tighter as the quantity of test data N increases; they range from 0.72 to 0.76 for NB, 0.73 to 0.79 for SVM, 0.82 to 0.86 for RF, 0.75 to 0.77 for KNN, and 0.74 to 0.80 for LR.
