Page 3: Basics of Machine Learning

Data is huge. People are expensive. Computation is cheap.

Page 4: Basics of Machine Learning

Use applied statistics to let the computers program themselves.

Regression vs Classification

Supervised Learning

Page 12: Basics of Machine Learning

RegressionUse continuous data to make a model that predicts where new data will fit.

Page 13: Basics of Machine Learning

ClassificationLabel data into "buckets", and make predictions on which bucket a new data point will fall into.
