New CLOCK method offers advanced time series clustering for dynamical systems

Researchers have introduced the Clustering Occupation Kernel (CLOCK) method, a new framework for clustering time series data derived from dynamical systems. CLOCK embeds time series into a reproducing kernel Hilbert space using a time-averaged occupation kernel, allowing for comparison of trajectories based on their RKHS norm. This approach approximates the kernel mean embedding of the invariant Sinai-Ruelle-Bowen (SRB) measure, making the dissimilarity metric akin to the Maximum Mean Discrepancy (MMD) between attractors. The method is designed to handle trajectories of varying lengths and irregular data spacing, and has demonstrated superior performance on synthetic and real-world EEG datasets compared to existing benchmarks.
