gle order of differentiability.</p>
<p><code>num_knots</code> argument specifies the number of knot points for each
covariate and for each <code>max_degree</code>. Fewer knot points can
significantly decrease runtime, but might be overly simplistic. When
considering <code>smoothness_orders = 0</code>, too few knot points (e.g., &lt; 50)
can significantly reduce performance. When <code>smoothness_orders = 1</code> or
higher, then fewer knot points (e.g., 10-30) is actually better for
performance. We recommen
