feat(training): LoRA pipeline with human-in-the-loop verification
- PEFT/LoRA fine-tuning (r=8, alpha=16) — only 1.2% params trainable - Data augmentation: templates + crypto slang (5x from 177→885 samples) - Human-in-the-loop CLI verification with persistent JSONL log - Disk-conscious: save_total_limit=1, ~6MB adapter size - CPU-friendly, single-file deployment - Tested: 1 epoch in ~4min on CPU, 6MB adapter

LoRA Fine-Tuning Pipeline for Crypto Sentiment & Emotion
|
||||
- PEFT/LoRA: trains only ~0.1% params (r=8, alpha=16)
|
||||
- Data augmentation from 145 labeled samples
|
||||
- Human-in-the-loop verification UI (CLI)
|
||||
- Disk-space conscious: streaming, no giant checkpoints
|
||||
- CPU-friendly, single-file deployment
