Check out the new article: Neural Networks in Trading: Adaptive Perception of Market Dynamics (STE-FlowNet).
The STE-FlowNet framework is built around the concept of spatiotemporal recurrent event processing, which enables the analysis of complex data sequences with a high degree of accuracy. The model receives a stream of events from the cameras and gradually builds an internal representation of motion, taking each new event into account and constantly updating its internal memory.
Each block of the model processes short sequences of events, carefully analyzing them in terms of their spatial and temporal dependencies. This makes it possible to detect motion even at high speeds and in dynamically complex scenes, where traditional methods often miss important details.
A stable representation of the dynamics is gradually formed, making it possible to predict future developments with a high degree of accuracy. The network's internal state contains local and global characteristics of motion, which enables the model to capture complex structures and predict patterns across various time scales.
The representation of the input data in STE-FlowNet is based on the operating principles of event cameras, which respond to changes in the logarithm of brightness intensity that exceed a specified threshold θ. Each event records the pixel coordinates, timestamp, and polarity of the change (increase or decrease in brightness), which can be written as e = {x, t, p}. In the context of financial markets, an analogy can be drawn to the execution of a trade, which results in a change in price or volume. Each entry contains critically important information about the system's current state and can serve as a signal for analyzing market dynamics. This makes the event stream a rich source of data capable of identifying even subtle trends and sharp fluctuations.
