answer:Supervised machine learning algorithms are trained on labeled data, which means the data is already tagged with the correct output. The algorithm learns to predict the output for new unlabeled data, based on the patterns in the labeled data. Examples of supervised algorithms are linear regression, decision tree, and support vector machine (SVM). Unsupervised machine learning algorithms are trained on unlabeled data, which means the data is not already tagged with the correct output. The algorithm learns to discover hidden patterns, clusters and associations in the data. Examples of unsupervised algorithms are k-means clustering, hierarchical clustering, and principal component analysis (PCA).
