Researchers have developed a new method called DySIB to infer the underlying state variables of a system from high-dimensional time-series data without supervision. This technique, applied to experimental data of a physical pendulum, successfully recovered a two-dimensional representation that accurately reflects the system's phase space, including its dimensionality and geometry. The learned coordinates correspond to the pendulum's angle and angular velocity, demonstrating the method's ability to extract interpretable dynamical information directly from raw data. AI
