• 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

from model.kronos import KronosTokenizer

tokenizer = KronosTokenizer.from_pretrained("NeoQuasar/Kronos-Tokenizer-base")
# Your tokenization code here

For Predictor

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(...)

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
