Abstract
This value τ (x) can be found by evaluating the minimum likelihood values fmin 0 (x) and fmin 0 (x). Unfortunately, it remains intractable to find the exact values of fmin 0 (x) and fmin 1 (x). To demonstrate this fact, we consider the Gaussian parametric setting as in Section 4, and evaluating the minimum likelihood in this case is equivalent to solving min−(µ− x) Σ− 1 (µ− x)− log det Σ st µ∈ Rd, Σ∈ Sd
