Homework 3
From
this page
you can find the USPS data (both training
and testing) in a "sparse format."
Use read.matrix.csr of the R e1071 package to
read it. Then
run your decision tree code used for HW 1 and 2
to do training and testing.
This data has 10 classes. Please make sure that
your decision tree code can handle such multi-class
problems.
Write a short report (<= 2 pages in English) to show
what you find.
