# Lab 9: Linear Categoriser

- Build a system that learns a linear classifier given data.
- Make a new java project.
- Put in an array of 2D points in two categories; the category can be
represented by a third integer point.
- Make a line that separates them. Remember, a line can be
represented many ways including by two points, and by the equation
x=my+b (where m is the slope constant and b is the offset from
the origin).
- In response to data, move the line. You can try the perceptron
learning rule, or just move it gradually.
- Try it with this data file.
- Try it with this data file.
- Can you make a plane for 3D?
