You would need the following
files for your home work:
Description of the files:
All the six files are ascii files.
data.dat contains data for a regression problem, there
is only one variable and one target. It contains 100 data points
class.txt, class2.txt and class3.txt contain data for a two class classification problem.
Each point has 2 features and the last column represents the class label (1 for
class 1 and 0 for class2).
trgIris.dat is an ascii file
containing data for a classification problem. The first four columns contains
the 4 features and the remaining
3 columns are the class labels. Note that in this data problem class 1,
2 and 3 are denoted by the vectors (1 0 0), (0 1 0) and (0 0 1). This
representation has certain advantages which we shall see later.
wr.txt is also an ascii
file. It contains data for regression problem, the first column is the x and
the other one the y.
The homework involves writing
programs and drawing plots. It is very convenient to use MATLAB for this
purpose. But you may use any other tool of your choice.
