Researchers have developed a new online least squares method for predicting outcomes in marginally stable, partially observed linear dynamical systems. This method aims to minimize cumulative squared prediction loss and compete with the best hindsight predictors. By incorporating predictive hints, the approach achieves logarithmic regret even with unbounded trajectories, offering an adaptive and instance-wise optimal predictor compared to traditional fixed-gain observers.
