What is Machine Learning?

Programming vs. Machine Learning?

Programming?

“Given a specification of a function f, implement f that meets the specification.”

Machine Learning?

“Given example (x, y) pairs, induce f such that y = f(x) for given pairs and generalizes

well for unseen x”

–Peter Norvig (2014)

Why Python?

Popular

Easier

Java:

public class HelloWorld { public static void main(String[], args) { System.out.println("Hello, World!"); } }

Python:

print "Hello, World"

Flexible

Coding Environments and Editors
