Researchers have developed a new method called Embedded Polygon Symbolic Transfer Entropy (EPSTE) to better estimate directed information flow between neural systems from EEG and MEG data. This approach reframes the estimation as a learnable problem by converting time series into symbolic tokens based on geometric primitives of waveform structure. A recurrent neural network with attention is trained to predict transfer entropy values from these symbolic representations, showing improved accuracy and stability compared to existing methods, particularly in recovering directed dependencies in neuroimaging data.
