Lecture 3 Blog, ECE662 Spring 2012, Prof. Boutin

Tuesday January 17, 2012 (Week 2)

This third lecture focused on how one can formalize the decision making process using two complementary approaches:

• finding a discriminant function (i.e., a real-valued function whose domain is the feature space);
• finding the decision boundary (i.e. a co-dimension one structure in the feature space).

We illustrated this using algebraic varieties, with an emphasis on hyperplanes (i.e. when the discriminant function is a degree one polynomial).
