Assignment 1

CS60050

 The purpose of this assignment is to force you to get familiar with Matlab.

1. Familiarize yourself with basics of Matlab.
2. The files q1x.dat and q1y.dat contain the inputs  x⁽ⁱ⁾  where each x⁽ⁱ⁾ is a real number, and outputs y which is a binary number (0 or 1) respectively for a binary classification problem, with one training example per row. Find a straight line which acts to separate the data. This is called the decision boundary.
   Plot the training data (your axes should be x1 and x2, corresponding to the two coordinates of the inputs, and you should use a different symbol for each point plotted to indicate whether the example had label 1 or 0).
   Also plot on the same figure the decision boundary.
3. The files q2x.dat and q2y.dat contain the inputs and outputs for a regression problem, with one training example per row. Implement linear regression on this dataset. Plot on the same figure the data and the straight line resulting from the fit.
