✓ Portable graph bundle live · download bundle · merged state

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

Extensive experiments show that TVRN outperforms existing methods in reconstruction quality under industrial video compression settings.

C2weakest assumption

The surrogate network provides sufficiently accurate gradient approximations for non-differentiable lossy codecs so that end-to-end optimization remains stable and does not introduce artifacts that would not appear with the true codec.

C3one line summary

TVRN combines invertible wavelet-based networks with a surrogate gradient approximator and compression-aware asymmetric design to improve frame-rate rescaling quality under real codecs.
