Interpretable deep convolutional model for nonlinear multivariate time series in complex systems
arXiv:2501.04339v2 Announce Type: replace-cross Abstract: We introduce the Deep Convolutional Interpreter for Time Series (DCIts), a deep-learning architecture for nonlinear multivariate time series that provides sample-specific, locally interpretable descriptions of the underlying interaction structure. Unlike standard black-box forecasters, DCIts learns a time- and lag-dependent transition tensor explicitly factorized into two components: a Focuser, which selects relevant source series and time lags via a sparse masking mechanism, and a Modeler, which assigns signed coefficients to these sel
The continuous drive for more transparent and explainable AI models, especially in complex systems like financial markets and climate science, necessitates new architectures addressing current black-box limitations.
This development offers a potential breakthrough in AI interpretability for time series data, crucial for high-stakes applications where understanding 'why' a prediction is made is as important as the prediction itself.
The ability to locally and sample-specifically interpret multivariate time series models moves away from purely predictive models towards those offering actionable insights into underlying causal or correlational structures.
