PRISM-BN - CPD-KL: leaderboard
Metric: CPD KL divergence (column-wise KL from the reference conditional probability table to the predicted one, Laplace-smoothed with epsilon 1e-6 and averaged over parent-state columns, then over all correctly recovered edges of all five domains; lower is better; zero-shot extraction of a parameterized Bayesian network from each of the 5,054 PRISM-BN text descriptions through the four-phase prompt pipeline; predicted node and state names are aligned one-to-one with the reference by a Llama 3.3 70B semantic judge). Source: arxiv.org. Saturation forecast: Around December 2026. 6 models tracked.
