## Problem 231 — rank:34

**Title:** T-cell-receptor recognition code

**Added binding assumptions (LaTeX):**

```latex
For finite uniform log-loss guarantees, restrict predictions to $[\epsilon_0,1-\epsilon_0]$ with fixed $0<\epsilon_0<1/2$, or impose an explicit integrability condition; otherwise a single confidently wrong prediction has infinite loss. Hold out entire correlated receptor and antigen families, not merely rows. Selection correction requires a positivity or sensitivity condition for genuinely assayed negatives and positives under the target sampling law.
