Abstract
A key component in monitoring and controlling of power systems is state estimation (SE). The state-of-the art SE technologies today operate on the basis of slow varying dynamics of the current network and make simplifying linearity assumptions. However, due to the non-linear/non-Gaussian nature of power grid, there is need for more accurate and real-time algorithms. In this paper, we introduce a new SE method, the Belief Condensation Filter (BCF), that aims to achieve these measures by approximating the true distribution of the state variables, rather than a linearized version as done for instance in Kalman filtering. Through simulations we show that in the presence of non-linearities and non-Gaussian noise, our general SE framework improves accuracy over best known Kalman-like filters, such as Unscented Kalman Filter (UKF) and asymptotically exact estimators, such as the particle filter (PF). We provide two sets of experimental results. Our analysis demonstrates the advantage of using BCF over UKF in (maximum entropy) non-Gaussian noise scenarios and over PF in terms of complexity and computation time.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
