Introduction to machine learning and data mining

How can a machine learn from experience, to become better at a given task? How can we automatically extract knowledge or make sense of massive quantities of data? These are the fundamental questions of machine learning. Machine learning and data mining algorithms use techniques from statistics, optimization, and computer science to create automated systems which can sift through large volumes of data at high speed to make predictions or decisions without human intervention.

Machine learning as a field is now incredibly pervasive, with applications from the web (search, advertisements, and suggestions) to national security, from analyzing biochemical interactions to traffic and emissions to astrophysics. Perhaps most famously, the $1M Netflix prize stirred up interest in learning algorithms in professionals, students, and hobbyists alike.

This class will familiarize you with a broad cross-section of models and algorithms for machine learning, and prepare you for research or industry application of machine learning techniques.

Background

We will assume basic familiarity with the concepts of probability and linear algebra. Some programming will be required; we will primarily use Matlab, but no prior experience with Matlab will be assumed. (Most or all code should be Octave compatible, so you may use Octave if you prefer.)

Textbook and Reading

There is no required textbook for the class. However, useful books on the subject for supplementary reading include Murphy's "Machine Learning: A Probabilistic Perspective", Duda, Hart & Stork, "Pattern Classification", and Hastie, Tibshirani, and Friedman, "The Elements of Statistical Learning".

Piazza

I use Piazza to manage student discussions and questions. Our class link is: http://piazza.com/uci/winter2015/cs178.

Matlab

Often we will write code for the course using the Matlab environment. Matlab is accessible through NACS computers at several campus locations (e.g., MSTB-A, MSTB-B, and the ICS lab), and student licenses are fairly inexpensive ($100) and even free for UCI students on personal machines; see here for instructions. If you use Octave, please be careful to use Matlab-compatible syntax (not Octave extensions), since otherwise I or the grader may be unable to interpret your code. For Octave, I suggest the SourceForge Octave binaries, e.g., Windows and Mac.

If you are not familiar with Matlab, there are a number of tutorials on the web:

• Union College / Cyclismo.Org tutorial, more complete
• TutorialsPoint
• A basic PDF guide by David Houcque
• A far more detailed PDF guide by Ed Overman

You may want to start with one of the very short tutorials, then use the longer ones as a reference during the rest of the term.

We will also use Matlab classes, including several classes that I've written for the course, to test and evaluate various classifiers. Here are some Notes on Matlab Object-Oriented Programming, using our k-nearest neighbor class as a working example.
