“Machine learning is a scientific discipline that explores the construction and study of algorithms that can learn from data.” (Wikipedia)
By studying and analysing accumulated big data, machine learning makes it possible to predict future behavioral patterns. For example, financial companies, by utilizing machine learning technology, can develop a program that can pre-emptively prevent financial frauds after analyzing massive data including credit card consumption and payment patterns.
For another instance, when a person living and consuming mainly in the metropolitan area suddenly moves to another area and purchases products that he or she has never bought before, credit card companies will automatically require additional identification verification procedure for security reasons.
The more data accumulates, the less possibility of error and more diverse services will be made possible.
