# Kronos Tokenizer - Fine-tuned on Custom Dataset
This is a fine-tuned version of [Kronos](https://huggingface.co/NeoQuasar/Kronos-Tokenizer-base) tokenizer,
adapted for better performance on custom financial datasets.
## Model Details
- **Model Type**: Tokenizer
- **Base Model**: NeoQuasar/Kronos-Tokenizer-base
- **Fine-tuned For**: Financial Time Series Prediction
- **Architecture**: Transformer-based with custom tokenization
- **Input**: OHLCV (Open, High, Low, Close, Volume, Amount) data
- **Output**: Multi-step time series predictions
## Training Details
- **Training Data**: Crypto Dataset (BTC, ETH, SOL, XAU)
- **Time Range**: 2022-01-21 to 2025-09-16
- **Frequency**: 5-minute intervals
- **Sequence Length**: 90 historical points
- **Prediction Horizon**: 10 future points
## Usage
### For Tokenizer
```python
from model.kronos import KronosTokenizer
tokenizer = KronosTokenizer.from_pretrained("NeoQuasar/Kronos-Tokenizer-base")
# Your tokenization code here
```
### For Predictor
```python
from model.kronos import Kronos, KronosTokenizer, KronosPredictor
tokenizer = KronosTokenizer.from_pretrained("NeoQuasar/Kronos-Tokenizer-base")
model = Kronos.from_pretrained("NeoQuasar/Kronos-Tokenizer-base")
predictor = KronosPredictor(model, tokenizer, device="cuda")
# Your prediction code here
predictions = predictor.predict(...)
```
### With the Original Repository
```python
# Clone the Kronos repository
git clone https://github.com/shiyu-coder/Kronos.git
cd Kronos
# Use the fine-tuned models
python examples/use_finetuned_model.py \
--csv_data your_data.csv \
--lookback 400 \
--pred_len 120
```
## Performance
This fine-tuned model shows improved performance on the target domain compared to the base model:
- **Domain Adaptation**: Specialized for the training dataset characteristics
- **Numerical Stability**: Improved convergence during fine-tuning
- **Inference Speed**: Optimized for the target sequence lengths
## Limitations
- Optimized for 5-minute financial data intervals
- May require re-tuning for different time frequencies
- Performance may vary on datasets with different statistical properties
