What is the difference between data mining and machine learning?
30
Data mining involves supervised learning, while machine learning involves unsupervised learning.
Data mining is a process for organizing and storing data, while machine learning is a technique for visualizing data.
Data mining focuses on extracting useful patterns and knowledge from large datasets, while machine learning focuses on developing algorithms that can learn and make predictions from data.
Data mining is used for text mining, while machine learning is used for image recognition.
