The Latent Truth: Why Prototype Explanations Need a Reality Check
The Latent Truth: Why Prototype Explanations Need a Reality Check Opening — Why this matters now Prototype-based neural networks have enjoyed a comfortable reputation in the XAI world: interpretable by design, or so the pitch goes. Their tidy habit of pointing at learned prototypes—“this looks like that”—has made them poster children for explainability. But 2025’s regulatory mood is unforgiving. In safety‑critical domains, interpretability must mean guarantees, not vibes.
