Details of Lecture 2, ECE662 Spring 2010
In the second lecture, we discussed the difference between finite and infinite feature spaces. We saw that, when the feature space of a decision problem is finite, then one does not necessarily need to use the decision theory techniques we will covered in ECE662. More specifically, if the feature space is relatively small, then one may be able to pre-compute the decisions for all possible feature values, and store the results in a look-up-table.
In the case of infinite feature spaces, we discuss the use of hypersurfaces in the feature space as a means of defining the separation between classes.
