Research Paper
Core Innovation
This paper presents CaRTeD, a novel framework that integrates temporal causal representation learning with irregular tensor decomposition. It uniquely formulates causal relationships among latent clusters in time series data and provides theoretical convergence guarantees. This approach improves interpretability and performance over existing methods in handling irregular, high-dimensional temporal data.
