"Wide-TSNet: A Novel Hybrid Approach for Bitcoin Price Movement Classification"
Overview
The paper introduces Wide-TSNet, a novel hybrid deep learning model designed for Bitcoin price prediction. Instead of using traditional numerical time-series analysis, the model transforms Bitcoin price data into images using Markov Transition Fields (MTFs). These images are then enhanced with histogram equalization and classified using Wide ResNets, a type of Convolutional Neural Network (CNN).
Key Contributions
✅ Image-Based Time-Series Analysis – Converts numerical Bitcoin price data into images to improve pattern recognition. ✅ Hybrid Deep Learning Model – Uses Wide ResNets, a powerful CNN architecture, for accurate classification. ✅ Tripartite Classification System – Unlike conventional models that only predict "Increase" or "Decrease," Wide-TSNet introduces a third class, "Stable," for more precise predictions. ✅ High Performance – Achieves 94% accuracy and an F1 score of 90%, outperforming traditional models like LSTM and ARIMA. ✅ Lightweight CNNs – The study compares Wide ResNets with SqueezeNet and EfficientNet, showing that even smaller models can perform well under specific conditions.
Methodology
Data Processing – Bitcoin price data is collected and pre-processed into a structured format.
Image Generation – The time-series data is transformed into MTF images, representing price transition probabilities.
Enhancement Layer – Histogram equalization is applied to improve contrast and pattern visibility.
Classification – The enhanced images are fed into a Wide ResNet CNN to classify price movements into Increase, Decrease, or Stable.
Experimental Validation – The model is tested against alternative deep learning techniques, proving its superior accuracy and efficiency.
Findings & Performance Comparison
Wide-TSNet achieved the highest accuracy (94%), outperforming other models.
RGB vs. Grayscale Testing – Grayscale images provided slightly better classification performance.
Resolution Impact – A 56×56 pixel size resulted in the best balance between accuracy and computational efficiency.
Computational Cost – Wide ResNet models require more memory (~15.3 GB), whereas SqueezeNet and EfficientNet are more resource-efficient but less accurate.
Conclusion & Future Research
Wide-TSNet provides a robust AI-powered approach for Bitcoin price forecasting, leveraging deep learning and computer vision. Future research will explore: 🔹 More lightweight CNN architectures for efficiency 🔹 Advanced feature extraction techniques 🔹 Real-world deployment for live crypto trading 🔹 Applications beyond Bitcoin, including other financial assets
Final Takeaway
The Wide-TSNet model represents a significant breakthrough in AI-based financial forecasting, offering a highly accurate and efficient method for predicting Bitcoin price movements.
