What is Machine Learning?
/məˈʃiːn ˈlɜːnɪŋ/
Everyday Example
Spotify's "Discover Weekly" playlist uses machine learning — it analyses your listening history and patterns from millions of other users to predict songs you'll enjoy. It gets better the more you use it.
publicReal-World Application
“Google Translate improved more in a single year after switching to machine learning (2016) than in its entire previous decade of rule-based programming. The system learned from billions of translated sentences.”
Did you know?
Arthur Samuel coined the term "machine learning" in 1959, defining it as giving computers "the ability to learn without being explicitly programmed." The field lay dormant until computing power and big data made it practical in the 2010s.
Key Insight
Machine learning doesn't understand — it correlates. A model that predicts cancer from X-rays doesn't know what cancer is; it's found pixel patterns that correlate with diagnoses. This distinction matters enormously for knowing when to trust it.
