Experiments
What we ran, in plain words, with the numbers behind each call.
The idea
Not a run. Anchor, sticky-note memory, what we test, and what we do not claim.
Read the ideaHow the model works
Not a run. Snapshot, notepad, and the write network Adam actually trains.

Not a run. Mixed results, the next steps in order, the baselines, and which datasets can support a claim.

Keep the notepad, 3 seeds
We re-ran keep-the-pad versus wipe-and-rebuild at two new training seeds on the same MIND-small split. All three seeds agree: keeping the notepad beats wiping it. For ~90% of users, the top recommendation was the same whether you kept or wiped the pad — the two strategies are nearly equivalent in what they recommend, but keep-the-pad scores slightly higher overall.
OpenRank-16 notepad on MIND
Factoring the notepad to rank 16 cuts per-user memory from 33 KB to 16.7 KB at a cost of 0.001 NDCG@10. Keep still beats wipe. Agreement with a full rebuild drops to 85.5%. Speed is unchanged because the rank-16 path is not yet optimised.
OpenMIND keep the notepad, confirmation
We reran the keep-the-pad test on a university RTX 4080 SUPER. Same MIND-small setup, one seed, validation only. Keeping the notepad again beat wiping it. This time the run finished: a checkpoint was written, and the keep-versus-wipe score check completed. Test split stayed sealed.
OpenMIND keep the notepad
On MIND-small we trained the snapshot-plus-notepad model two ways: wipe the notepad and rebuild it from the last twenty clicks, or keep it across visits like a live app. Keeping the pad ranked better on validation. One seed. Training stopped early after the score peaked.
OpenMIND snapshot and notepad
On MIND-small news ranking we freeze each user's first training clicks as a stable snapshot, then let a small notepad of fast weights adapt on later clicks. Across three model seeds, snapshot plus notepad beat a moving history mean. Validation only. The held-out test split stayed sealed.
OpenAmazon snapshot and notepad
On Amazon reviews we used the same four-row design with frozen product embeddings. The notepad still added a large ranking gain. A moving profile beat the earliest-product snapshot when memory was on. One seed only. A stale shopping snapshot may be the wrong slow state for this task.
