A Analysis details for the linear model

Here, we provide details for the derivation of (9). Now, consider the determinants in (2). That is, we can enforce a looser restriction on firing rates by bounding the power used by the filter. In practice, we bound the square of this expression, which yields the continuous objective (9). As noted in Section 3.1 the optimal solution for (9) takes the form (10). Our starting point is (9).
