用于加密货币价格预测的自适应时序融合变换器

文章 arXiv papers · 作者: Arash Peik et al.

总结

本文提出一种自适应时序融合变换器方法,用于短期加密货币价格预测。为应对非平稳性和剧烈价格变化,研究将时间序列划分为长度可变的子序列,并以相对最大值作为结尾:即从此前最低点算起的涨幅超过某个阈值的点。此方法旨在标记有意义的上涨阶段,同时滤除部分噪声。一个片段末尾的固定长度模式决定下一个片段的类别,从而根据先前条件对后续价格路径分组。

研究为每个类别分别训练一个 TFT,根据下一片段的初始观察值预测其走势。实验使用 ETH-USDT 的十分钟数据,测试期为两个月。本文报告称,与固定长度的 TFT 和 LSTM 基准相比,该方法的预测准确度和模拟交易盈利能力更高。结果仅适用于所述资产、时间间隔和测试期;本文未证明该方法能够迁移至其他加密货币、市场状态,或计入执行成本后的实盘交易。

核心观点

  • 当从此前最低点算起的涨幅超过阈值时,长度可变的片段结束。
  • 一个片段末尾的固定长度模式为下一个片段确定类别。
  • 针对每种模式类别分别训练 TFT 模型,以预测后续片段。
  • 报告称,ETH-USDT 测试在准确度和模拟盈利能力方面优于固定长度的 TFT 和 LSTM 基准。
  • 证据仅限于所述资产、采样间隔和测试期。

# Adaptive Temporal Fusion Transformers for Cryptocurrency Price Prediction









Precise short-term price prediction in the highly volatile cryptocurrency market is critical for informed trading strategies. Although Temporal Fusion Transformers (TFTs) have shown potential, their direct use often struggles in the face of the market's non-stationary nature and extreme volatility. This paper introduces an adaptive TFT modeling approach leveraging dynamic subseries lengths and pattern-based categorization to enhance short-term forecasting. We propose a novel segmentation method where subseries end at relative maxima, identified when the price increase from the preceding minimum surpasses a threshold, thus capturing significant upward movements, which act as key markers for the end of a growth phase, while potentially filtering the noise. Crucially, the fixed-length pattern ending each subseries determines the category assigned to the subsequent variable-length subseries, grouping typical market responses that follow similar preceding conditions. A distinct TFT model trained for each category is specialized in predicting the evolution of these subsequent subseries based on their initial steps after the preceding peak. Experimental results on ETH-USDT 10-minute data over a two-month test period demonstrate that our adaptive approach significantly outperforms baseline fixed-length TFT and LSTM models in prediction accuracy and simulated trading profitability. Our combination of adaptive segmentation and pattern-conditioned forecasting enables more robust and responsive cryptocurrency price prediction.
