# LLapDiff Checkpoints

This repository hosts checkpoint archives for the LLapDiffusion project.

## Archives

- `llapdiffusion_baseline_checkpoints.zip`: longest/default-horizon extrapolation baseline checkpoints. It contains 56 checkpoints across 7 datasets and 8 baselines.
- `llapdiffusion_longest_horizon_artifacts.zip`: LLapDiff longest-horizon artifacts trained from commit `59f4427b3a0c71e941f6ff4f7f047f80cad2dfd6`.
- `llapdiffusion_x0_diffusion_checkpoints.zip`: x0-parameterized LLapDiff diffusion checkpoints for the same seven longest/default horizons. This archive is separate from the v-prediction LLapDiff artifact archive and does not include VAE or summarizer checkpoints.

## Baseline archive

The baseline archive has two completion groups:

- 35 full-loop checkpoints for `dlinear`, `mtan`, `patchtst`, `t_patchgnn`, and `timegrad`.
- 21 very heavy checkpoints for `neuralcde`, `mr-diff`, and `contiformer`.

The one-batch checkpoints are included for completeness and load/evaluation plumbing checks; they are not comparable full-training baseline results.
Checkpoint names follow `checkpoints/<dataset>_h<horizon>_<method>.pt`.
`MANIFEST.csv` records file sizes, SHA256 checksums, and `completion_mode`.

Current `llapdiffusion_baseline_checkpoints.zip` SHA256: `3afc405489dd061a92bb5b66d82cca4c12ae56b43fefc12e6a191ded9d22d3f4`

## LLapDiff artifact archive

The LLapDiff artifact archive covers `bms_air h168`, `uci_air h168`, `physionet h12`, `noaa_us h168`, `noaa_uk h168`, `us_equity h100`, and `crypto h100`.
For each dataset, it includes VAE ELBO/reconstruction best checkpoints, summarizer best, and LLapDiff best.

Historical Hugging Face revisions may contain earlier archive states.

## LLapDiff x0 Diffusion Checkpoints

`llapdiffusion_x0_diffusion_checkpoints.zip` contains x0 LLapDiff diffusion checkpoints only: `best` and `last` checkpoints for `bms_air h168`, `uci_air h168`, `physionet h12`, `noaa_us h168`, `noaa_uk h168`, `us_equity h100`, and `crypto h100`.

The archive preserves repo-relative paths under `ldt/output/<dataset>/mode-x0/pred-<horizon>/` and includes `metadata/x0_manifest.json`, `metadata/sha256sums.txt`, and the seven `ldt/results/x0/*.json` summary files. Reuse VAE and summarizer artifacts from `llapdiffusion_longest_horizon_artifacts.zip`.

Current `llapdiffusion_x0_diffusion_checkpoints.zip` SHA256: `9f64af580ea81a11fab2616de5e5d1125405906ce79fa6ed7b03e18e3477cea4`

## CSDI 30% Imputation Checkpoints

`llapdiffusion_csdi_mask30_imputation_checkpoints.zip` contains CSDI target-horizon imputation checkpoints for PhysioNet h12, Crypto h100, and NOAA UK h168. These were trained/evaluated with a random 30% observed-target holdout and 25 evaluation samples. The archive is separate from the extrapolation baseline archive and the LLapDiff artifact archive.
