::PRISM: one backbone, three signal types, no per-modality tuning.
Hybrid linear-recurrent backbones win on language, but their design choices are language-specific. PRISM interleaves Mamba-2-style SSD blocks with Gated Delta Rule blocks at 3:1 and applies the same backbone — identical hyperparameters — to 12-lead ECG, spoken commands, and sequential images. Both mixers are implemented from scratch and held honest by numerical-equivalence tests against the production kernels.
The follow-up, MoM, lets a per-token router choose which memory primitive handles each token instead of fixing the ratio by hand. The first spike gate failed: routing doesn't collapse, but recall lags the GDR-only baseline. That's the current problem.
Pipeline validation — PTB-XL super-diag, val macro-AUC
hidden 64 · 4 layers · 2 epochs · 1 seed · RTX 5060. Pipeline validation, not the paper's numbers — the full matrix runs at ~8M params, 3 seeds.
Projects — an index
::everything above is original work — no forks. the full list, including the experiments that didn't make the cut, is on github.
Toolbox
::the laptop runs NixOS; two of the repos are just dotfiles. PRISM trains on a single RTX 5060 — small hardware is a feature: if the architecture doesn't fit in 8 GB, the architecture changes.
