ProDG: Prototypes for Data-Free Generative Post-Hoc Explainability

Jacek Tabor, {\L}ukasz Struski, Magdalena Tr\k{e}dowicz, Piotr Borycki, Przemys{\l}aw Spurek

ProDG generates high-fidelity visual prototypes for explaining neural network decisions using only the model's weights and no real data.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

a novel framework that leverages generative models to synthesize pure, high-fidelity prototypes directly from the frozen model's weights, completely eliminating the dependency on any external data.

C2weakest assumption

That generative models can reliably produce prototypes whose visual and semantic properties match those that would have been selected from real data, and that these synthetic prototypes yield faithful explanations for the original model's decisions.

C3one line summary

ProDG uses generative models to create data-free prototypes from model weights for post-hoc explainability of image predictions.
