- a)
- Create points from two intersecting lines and run the algorithm with option
*LineMix*and 2 clusters. Click repeatedly on*EM 1 Step*to run the algorithm. Repeat this experiment with different cutting angles of the lines and analyze if this has an effect on the number of iterations until convergence. - b)
- Create points in a ring around the center with the button
*RingPts*. Try to fit a mixture of lines model (with*EM Run*) to this distribution and analyze what happens when you change the number of lines. Do the same experiment with mixtures of Gaussians and describe what you find.
