lora-wave-session-dataset
Training data for Maelstrome/lora-wave-session — a Gemma 4 E2B fine-tune for the WAVE wellness/companion app. Three structured-output surfaces unified into one dataset.
Surfaces
| Surface | Examples | What it does |
|---|---|---|
check_in |
1,534 | Multi-turn patient check-in with structured turn sequencing |
phase_narration |
1,553 | Six-line patient-facing phase narration |
reflection |
1,190 | Reflection plan with a concrete next step |
| Total | 4,277 |
All three surfaces emit strict JSON, no markdown, no analysis voice, in patient-facing tone.
Structure
Each row is a JSON object with:
{
"id": "<uuid>",
"splitKey": "<group key for stratification>",
"surface": "check_in | phase_narration | reflection",
"sourceLoraId": "lora-check-in-1 | lora-check-in-2 | ... | lora-phase-narration | lora-reflection",
"sourceStatus": "draft | ready | synthetic_draft",
"input": { ... },
"output": { ... }
}
The input/output schemas are surface-specific; the LoRA learns to map input → JSON-stringified output per the gemma-4 chat template.
Splits
The training run uses an 80/10/10 stratified split (seed 7, stratified by splitKey):
| Split | Count | check_in | phase_narration | reflection |
|---|---|---|---|---|
| Train | 3,421 | 1,225 | 1,251 | 945 |
| Validation | 428 | 165 | 155 | 108 |
| Test | 428 | 144 | 147 | 137 |
This is computed at training time, not pre-baked in the file. To reproduce, use the same seed and stratification key.
Source LoRAs
Earlier WAVE iterations had per-surface LoRAs (lora-check-in-1 through lora-check-in-5, lora-phase-narration, lora-reflection). This dataset unifies their training data so a single adapter can serve all surfaces.
| Source LoRA | Count |
|---|---|
lora-phase-narration |
1,553 |
lora-reflection |
1,190 |
lora-check-in-1 |
288 |
lora-check-in-2 |
336 |
lora-check-in-3 |
335 |
lora-check-in-4 |
335 |
lora-check-in-5 |
240 |
Status mix
| Status | Count | Note |
|---|---|---|
synthetic_draft |
2,645 | Synthetic, model-generated draft data |
draft |
1,574 | Human-drafted but not clinician-validated |
ready |
58 | Clinician-validated |
Token-length stats (Gemma 4 tokenizer)
| Stat | Tokens |
|---|---|
| p50 | 518 |
| p90 | 1,752 |
| p95 | 1,833 |
| p99 | 2,104 |
| max | 2,227 |
max_seq_length=3072 is comfortable; 2048 would truncate the longest ~5%.
Provenance and intended use
Synthetic and draft training data assembled for the WAVE app, a wellness/reflection tool. No real PHI. Not a clinical dataset, not validated for medical decision-support, not a substitute for professional advice.
Limitations
- Mostly synthetic and draft-status data. Only ~1% is clinician-reviewed.
- English only.
- The structured JSON schemas are WAVE-specific; consumers should expect to either accept those schemas or transform them.
- Wellness scope only — see model card for downstream use limitations.
