Data mining juga dipakai di dalam banyak aspek seperti dalam computer, sains dan teknik, pemerintahan, penegakan hukum, obat-obatan, olahraga, dan masih banyak lainnya. Ada tiga metode dari data mining yaitu, Prediction, Association, dan Segmentation. Tipe Prediction terbelah menjadi tiga yaitu Classification, Regression, dan Time Series.
Data Science Metodologi Ringkas
Predictive modeling is a process that uses data mining and probability to forecast outcomes; for example, a predictive model might be used to determine whether an email is a spam or not. For predictive modeling, data scientists use a training set that is a set of historical data in which the outcomes are already known. This step can be repeated.
