comment Geometric interpretation of the addition of linear equations in general form
As I was studying the question of how to visualize the decision boundaries of a softmax regression model, I realized that the parameters of the decision boundary between class $i$ and $j$ can be computed as $\theta_i - \theta_j$, where the $\theta$s can be interpreted as the parameters of linear equations in general form (as is clear at least for the 2D example I've been studying: cjauvin.blogspot.ca/2013/10/softmax-regression-101.html). I've been trying really hard to find an intuitive way to understand this in geometric terms, to no avail.

comment Geometric interpretation of the addition of linear equations in general form
Thank you for this interesting answer! I was led to this question through a very indirect path (i.e. a machine learning problem), and I'm not sure if it makes sense to talk about it here, but I'll take a shot at it anyway..

comment Summing 2 to the power of the subset sums of a power set
Many thanks! I am puzzled and greatly impressed by your speed.. is that a reasoning that you made on the fly, or you had somehow thought about a related problem before?
