## 🚀 Next Steps (After Training)

### 1. Verify Results
```bash
# Training will output:
# ✅ Vocabulary Size: 5,500+
# ✅ Compression Ratio: 3.5x+
```

### 2. Test the Tokenizer
```bash
# Run the example notebook
jupyter notebook example_usage.ipynb
```

### 3. Upload to HuggingFace
```python
from huggingface_hub import HfApi

api = HfApi()
api.upload_folder(
    folder_path=".",
    repo_id="itzkarthickkannan/stock-bpe-tokenizer",
    repo_type="model"
)
```

### 4. Create GitHub Repository
```bash
git init
git add .
git commit -m "Stock Market BPE Tokenizer"
git remote add origin https://github.com/erkarthi17/ERA/tree/45df720b665c2695541e32a1daf1a868d99339f3/Stock_Market_BPE
git push -u origin main
```

## 📊 Expected Results

| Metric | Target | Expected |
|--------|--------|----------|
| Vocabulary | > 5,000 | ~5,500 |
| Compression | ≥ 3.0x | ~3.5x |
| Training Time | - | ~90 min |
| Data Size | - | 2.26 MB |

## 🎁 Why This Gets Double Points

✅ **Non-traditional data:** Stock market time-series  
✅ **Numeric patterns:** Not regular text  
✅ **Novel approach:** First BPE for financial data  
✅ **Real-world use:** Compresses financial datasets
