Abstract
In this work, we present some examples of applications of the so-called Rao-Blackwellised particle filter (RBPF). RBPFs are an extension to particle filters (PFs) which are applicable to conditionally linear-Gaussian state-space models. Although RBPF introductions and reviews may be found in many existing sources, going through the specific vocabulary and concepts of particle filtering can sometimes prove to be time-consuming for the non-initiated reader willing to experiment with alternative algorithms. The goal of the paper is to introduce RBPF-based methods in an accessible manner via a main algorithm, which is detailed enough to be readily applied to a wide range of problems. To illustrate the practicality and the convenience of the approach, the algorithm is then tailored to two examples from different fields. The first example is related to system identification, and the second is an application of speech enhancement

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
