# Bayesian Inference
**Entity class:** Probabilistic And Inverse-Problem Layer concept
**Bayesian Inference** is a probabilistic construct for updating uncertainty about hidden states or competing explanations when evidence arrives. The operational value of Bayesian Inference lies in preserving time, provenance, confidence, and alternative explanations.

The page records capability and analytic function. Any claim of a named operational deployment remains subject to the [[wiki/Counterterrorism Predictive Graph Evidence Ladder|evidence ladder]]. The analytic state should distinguish ground truth, observed evidence, inferred state, and predicted state.

## Austin defense-technology role
A probabilistic model updates beliefs in light of observations. The article names the method among Oden's tools for reconstructing hidden physical conditions and qualifying predictions.
Oden develops mathematical and computational methods for reconstructing, predicting, and influencing complex systems. The article identifies named interfaces with ARL:UT, DTRA-funded radiation modeling, and Meyers-group biosurveillance. Shared methods connect the domains; a documented project, sponsor, or transfer establishes each particular institutional relationship.
