We thank all reviewers for the careful reviews. All four recommend acceptance. Most questions ask for analyses of results we already have, plus a few new runs. Every result below, with tables and videos, is on one anonymous page: https://memorizon-rebuttal.pages.dev/
New in this response
- Retrieval hit rate and training distribution for 100 / 200 / 400 s (btN3): https://memorizon-rebuttal.pages.dev/e1/. Longer spans add available first visits (83% -> 91% -> 96% of scored chunks have one in range). Given one is available, top-6 retrieves it about 90% of the time at every span.
- Bank-content ablation on the 200 s and 400 s models (btN3): https://memorizon-rebuttal.pages.dev/e2/. With no bank, or a bank from another video, Gain falls to about zero; random frames from the same video recover about a third.
- Camera following with CaR, and returns stratified by realized yaw error (btN3): https://memorizon-rebuttal.pages.dev/e3/. Among well-aligned returns, CaR is within seed noise of our 100 s and 400 s models and about 0.06 Revisit below the 200 s model. We report this plainly and no longer claim an advantage over CaR in camera following (the two follow the path equally well).
- Cost (m2mq, MjTC): https://memorizon-rebuttal.pages.dev/e5/. Pose scoring takes 32 ms per chunk at 400 s of history on one CPU thread, about 1% of the 3.2 s needed to generate a chunk. Chunk latency is flat from 10 s to 400 s of history, and peak allocated GPU memory equals a sliding window (22.6 GB).
- Zero-shot on real capture (KgbX, m2mq): https://memorizon-rebuttal.pages.dev/e6/. 20 DL3DV-10K scenes from one real first frame and the scene's own camera path. The path is followed (correlation 0.79 / 0.73); we do not claim pixel fidelity.
- Occlusion of retrieved frames (MjTC), measured with monocular depth: https://memorizon-rebuttal.pages.dev/e7/. 24-49% of the in-frustum content of retrieved frames is occluded, versus 38-65% for random frames that pass the same frustum test.
- Independent training seeds and bank noise [PENDING: G2, G1]: runs finished training, results to be posted in a follow-up comment.
Changes to the paper
- Camera following moves into Sec. 4.2; the cross-system ranking is called indicative, and within-backbone ablations are the primary evidence for memory.
- The 400 s explanation in Sec. 4.3 is now a hypothesis; 200 s is best in our tested setup.
- The abstract reads "bounded by k x K"; novelty claims in Sec. 1 are narrowed to the union-bank mechanism.
