- Supervised Learning

- Unsupervised Learning

- PredictionIO

Page 3: Machine learning

Learning algorithmsof large datasets

Page 4: Machine learning

Field of study that gives computers the ability to learn without being explicitly programmed.- Arthur Samuel (1959)

Page 5: Machine learning

Training DataLearning

Algorithm

Hypothesis

(Mathematical model)

Predicted y(feedback)

Test Data

Page 6: Machine learning

- Derives from AI theories

- Machine Learning is NOT pattern matching!

- Mathematical induction with certain confidence intervals in mind

Unsupervised Learning

Page 20: Machine learning
Page 21: Machine learning

Unsupervised Learning

- No test data- You need to find the structure yourself
