# EasyNLA warmstart data (non-compositional, Qwen3-8B layer 24)
Supervised warm-start data for [EasyNLA](https://github.com/asherps/EasyNLA) —
train a **natural-language autoencoder** on Qwen3-8B: an activation-verbalizer
(AV) that explains a layer-24 residual activation in natural language, and an
activation-reconstructor (AR) that maps the explanation back to the activation.
Each row carries one **raw** (unnormalized) layer-24 activation captured while
Qwen3-8B read a FineFineWeb document (position ≥ 50 tokens), plus a
Claude-written "gold" explanation of what the model was representing there.
| config | split | rows | docs |
|---|---|---|---|
| `av_sft` | train | 363,961 | 36,734 |
| `av_sft` | validation | 7,307 | 737 |
| `ar_sft` | train | 363,988 | 36,734 |
| `ar_sft` | validation | 7,405 | 747 |
## Columns
- `prompt` — chat messages for the AV (with the `<INJECT>` marker placeholder)
in `av_sft`; the AR critic prompt text in `ar_sft`
- `response` (`av_sft` only) — the gold explanation the AV imitates
- `activation_vector` — raw layer-24 residual, `list<float32>[4096]`
- `doc_id`, `n_raw_tokens`, `activation_layer`,
`detokenized_text_truncated` (the source text up to the extraction position)
Each parquet has a matching `<name>.parquet.nla_meta.yaml` **sidecar** — the
contract EasyNLA trainers assert at startup (marker token IDs, prompt
templates, `d_model`, scales). Keep them next to the parquets.
## Splits
Document-level and deterministic: a doc goes to **validation** iff
`zlib.crc32(doc_id) % 1000 < 20` (`nla/val_split.py::is_val_doc(doc_id, 20)`,
~2% of docs). No document's rows are split across train/validation, and the
`av_sft` / `ar_sft` configs come from disjoint document sets by construction
(stage-1 of the EasyNLA datagen pipeline).
## Use with EasyNLA
```bash
huggingface-cli download asher577/easynla-warmstart-data --repo-type dataset \
--local-dir <data>
python -m nla.train_sft --mode av --base-ckpt Qwen/Qwen3-8B \
--parquet <data>/av_sft_train.parquet --sidecar <data>/av_sft_train.parquet \
--heldout-parquet <data>/av_sft_val.parquet --save-dir <ckpts>/av
python -m nla.train_sft --mode ar --base-ckpt Qwen/Qwen3-8B \
--parquet <data>/ar_sft_train.parquet --sidecar <data>/ar_sft_train.parquet \
--heldout-parquet <data>/ar_sft_val.parquet --save-dir <ckpts>/ar
```
Provenance: source text from FineFineWeb (ODC-By); explanations generated with
Claude (claude-sonnet-4-6); activations from Qwen/Qwen3-8B. The `doc_id`
strings are opaque keys from the generating pipeline.
