Check out the new article: Neural Networks in Trading: Time Series Forecasting Using Adaptive Modal Decomposition (ACEFormer).

We invite you to explore the ACEFormer architecture — a modern solution that combines the effectiveness of probabilistic attention with adaptive time series decomposition. This article will be useful for those seeking a balance between computational performance and forecast accuracy in financial markets.

Efforts to develop predictive models date back to the late twentieth century. Early neural network architectures demonstrated that it was, in principle, possible to train models to forecast market movements. However, these approaches were unable to retain information over long time horizons and quickly lost track of events that had occurred only a short time earlier.

The introduction of LSTM networks improved this situation. Thanks to their memory mechanisms, LSTM models were capable of preserving important patterns over extended periods. They quickly became widely adopted for time series forecasting. Nevertheless, it is not that straightforward. Financial time series present differ from conventional sequential data. They are irregular, often with uneven intervals between ticks. They contain a large number of short-lived spikes that carry little meaningful information about the underlying market trend.

High-frequency trading poses an especially significant challenge. It generates what is commonly referred to as market noise — repeated quote fluctuations occurring within extremely short time intervals. These fluctuations obscure genuine trends, increase data instability, and overwhelm predictive models with insignificant events. As a result, even sophisticated neural architectures may begin focusing on distracting short-term variations rather than the information that truly matters.

To address these challenges, the paper "An End-to-End Structure with Novel Position Mechanism and Improved EMD for Stock Forecasting", introduces the ACEFormer framework — an integrated architecture for financial time series analysis specifically designed for high-frequency trading environments. Rather than representing a single predictive model, ACEFormer combines several complementary components, each addressing a distinct task: noise filtering, irregular temporal interval modeling, and selective attention to the most informative market movements.
