HAELT: A Hybrid Attentive Ensemble Learning Transformer Framework for
High-Frequency Stock Price Forecasting
High-frequency stock price prediction is challenging due to non-stationarity,
noise, and volatility. To tackle these issues, we propose the Hybrid Attentive
Ensemble Learning Transformer (HAELT), a deep learning framework combining a
ResNet-based noise-mitigation module, temporal self-attention for dynamic focus
on relevant history, and a hybrid LSTM-Transformer core that captures both
local and long-range dependencies. These components are adaptively ensembled
based on recent performance. Evaluated on hourly Apple Inc. (AAPL) data from
Jan 2024 to May 2025, HAELT achieves the highest F1-Score on the test set,
effectively identifying both upward and downward price movements. This
demonstrates HAELT's potential for robust, practical financial forecasting and
algorithmic trading.
