**Question:** On the slide 6/23 why do we have flat regions on the graph?

**Answer:** Chances are, that during this flat regions, we don't change the classification of any point. We may change the coefficients on some steps, but most of the time we are just looking at the points, which are classified correctly, so we even don't change any coefficients (and probably we count these steps as iterations too and, therefore, getting flat regions in the graph of

and

for hundreds of iterations).
