Researchers have developed a novel approach for monitoring dynamic processes in high-dimensional data by integrating topological data analysis (TDA) with machine learning. This method represents multivariate time-series data as manifolds, using topological descriptors to capture structural information. A neural ordinary differential equation is then employed to model the evolution of these topological structures over time. Experiments on industrial process data demonstrate the effectiveness of this trajectory-based event detection system, showing superior performance compared to reconstruction-based methods like principal component analysis and autoencoders, as well as a Koopman autoencoder approach.
