Learning algorithmsof large datasets
Field of study that gives computers the ability to learn without being explicitly programmed.- Arthur Samuel (1959)
Training DataLearning
Algorithm
Hypothesis
(Mathematical model)
Predicted y(feedback)
Test Data
- Derives from AI theories
- Machine Learning is NOT pattern matching!
- Mathematical induction with certain confidence intervals in mind
Natural Language Processing
I shot an elephant wearing my pajamas
Supervised Learning
Supervised Learning
- ‘right’ answers were given already
Unsupervised Learning
Unsupervised Learning
- No test data- You need to find the structure yourself
