ACEFormer: Denoising and Attention for Financial Time-Series Forecasting

Summary

The article presents ACEFormer, a neural architecture for forecasting financial time series, especially noisy and irregular high-frequency data. Its pipeline first smooths inputs with convolutional filters, then applies an adaptive ensemble empirical mode decomposition method to remove the first intrinsic mode function, which is treated as high-frequency noise. The remaining series is processed with temporal awareness and attention components before a fully connected network produces forecasts.

The account also describes volatility and signal handling only in broad terms, while its main technical detail is the decomposition and probabilistic attention approach: attention scores are estimated from sampled keys so computation focuses on selected time steps, then later layers capture local patterns and wider context. The article outlines an MQL5 and OpenCL implementation, but the presented installment focuses on major components rather than a complete integrated model. It offers architectural reasoning and implementation discussion, not reported comparative performance or evidence that forecasts are profitable; claims about noise reduction and accuracy should therefore be treated as design aims rather than demonstrated trading results.

Key ideas

• ACEFormer combines signal denoising, temporal modeling, attention, and a neural prediction head.
• Its ACEEMD stage removes the first intrinsic mode function to suppress high-frequency oscillations.
• Probabilistic attention estimates which time steps matter and limits attention computation to selected positions.
• Convolution and max pooling extract local patterns, while a later attention layer can capture broader sequence context.
• The article describes implementation components but does not provide comparative performance evidence or establish profitability.
