Abstract
Day by day, Bayesian networks are getting popular for solving real-life problems. However, it is difficult to build Bayesian decision networks (BNs) to solve large scale real world problems. Using object-oriented Bayesian networks (OOBNs) is one strategy to deal with the scalability issue. OOBNs make it possible by providing researchers with the facility to design classes and build models with a modular and hierarchical architecture, which increases reuse and maintenance facilities. Sharing properties down the hierarchy of classes, known as “inheritance” in OO-paradigm, is a key idea to increase the reusability and tackle scalability issue. It means that one can share or reuse components and behaviors of an entity known as object or class. Previously, a framework of OOBN was proposed to contain inheritance and all other aspects of OO-paradigm. Recently, in 2022, an extension was proposed to learn hierarchy of OOBN classes. However, such an extension is still suboptimal. In this paper, we identify some scopes to improve the learning technique. We propose and implement a new algorithm and then analyze it empirically and asymptotically. We use both synthetic and real-world data in the empirical analysis. The analysis shows that our proposed algorithm is more effective and efficient, especially in terms of reusability.

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
