Computational insight extraction
Data science is the field that extracts insights from large datasets using statistics, programming, and machine learning.
It combines techniques from mathematics, computer science, and domain expertise to find patterns, make predictions, and inform decisions.
A data scientist might analyze customer behavior, detect fraud, or train algorithms to recognize images.
The field emerged as computing power and data collection exploded in the early 21st century.
