## Outline

This is an introductory course in machine learning (ML) that covers the basic **theory, algorithms, and applications**. ML is a key technology in Big Data, and in many financial, medical, commercial, and scientific applications. It enables computational systems to adaptively improve their performance with experience accumulated from the observed data. ML has become one of the hottest fields of study today, taken up by undergraduate and graduate students from 15 different majors at Caltech. This course balances theory and practice, and covers the mathematical as well as the heuristic aspects. The lectures below follow each other in a story-like fashion:

- What is learning?
- Can a machine learn?
- How to do it?
- How to do it well?
- Take-home lessons.

The 18 lectures are about 60 minutes each plus Q&A. The content of each lecture is color coded:

**theory; mathematical**

technique; practical

analysis; conceptual

technique; practical

analysis; conceptual

## Live Lectures

This course was broadcast live from the lecture hall at Caltech in April and May 2012. There was no 'Take 2' for the recorded videos. The lectures included live Q&A sessions with online audience participation. Here is a sample of a live lecture as the online audience saw it in real time.
