InstructTime v2.1

What's New

Cross-Domain Autoregressive Pretraining

• Added run_pretrain_universal.py for multi-domain joint pretraining across all five signal domains (ECG, EEG, FD, HAR, RWC)
• Supports weighted domain sampling for balanced cross-domain training
• Mixed-precision training with cosine warmup scheduling and early stopping
• Deterministic reproducibility setup for consistent results

Bug Fixes

• Fixed off-by-one error in average loss and metric calculation in TStokenizer Trainer class (loss_sum / idx → loss_sum / (idx + 1))

Documentation

• Updated README to reflect the correct three-stage training pipeline:
  1. TStokenizer training
  2. Cross-domain autoregressive pretraining (run_pretrain_universal.py)
  3. Supervised fine-tuning (Universal + Adaptation)
• Added run_pretrain_universal.py to project structure

Changed Files

• run_pretrain_universal.py (new)
• TStokenizer/process.py
• README.md
