## Problem 102 — rank:76

**Title:** What computation does a neural circuit perform?

**Added binding assumptions (LaTeX):**

```latex
State whether $P_{M_i}$ uses fixed parameters, posterior predictive laws or a composite family. A uniform mechanism-discrimination claim requires a minimum over the allowed nuisance parameters, as in Problem~45. Positive-scale objective normalization does not remove every inverse-control equivalence. Report the experimentally distinguishable computation class rather than a unique verbal interpretation of the circuit.
