An Optimal Approximation Algorithm for Bayesian Inference
Approximating the inference probability Pr X xjE e in any sense even for a single evidence node E is NP hard This result holds for belief networks that are allowed to contain extreme conditional probabilities that is conditional probabilities arbitrarily close to Nevertheless all previous approximation algorithms have failed to approximate e ciently many inferences even for belief networks with...
متن کاملAn Approximation to Discrete Optimal Feedback Controls
We study discrete solutions of nonlinear optimal control problems. By value functions , we construct difference equations to approximate the optimal control on each interval of " small " time. We aim to find a discrete optimal feedback control. An algorithm is proposed for computing the solution of the optimal control problem. 1. Introduction and statement of the problem. For nonlinear analytic...
متن کاملAn On-line Addendum to: “Strategic Commitments for an Optimal Capacity Decision Under Asymmetric Forecast Information”
Proof of Theorem 4. For wa ∈ [c + ck, rck w−c ], we have the boundary equilibrium. From its definition, yb(ξ) is decreasing in wa (that is, dyb(ξ) dwa < 0) and yb(ξ) = μ + ξ + G−1( r−c−ck r ) when wa = c + ck. The total supply chain profit at the boundary equilibrium is Πtot(yb(ξ), yb(ξ), ξ) = rEmin(μ + ξ + , yb(ξ)) − (c + ck)y(ξ) from Equations (16) and (17). This function is concave and incre...
متن کاملTinnitus neural substrates: an addendum.
Since its initial publication in 1995, the International Tinnitus] ournal (IT J) has been dedicated to providing its readers with state-of-the-art information, not only of basic science but of its integration and translation into clinical medicine for achieving a cure for all clinical types of tinnitus. A report that integrates the clinical and basic science identifying neural substrates and bi...
متن کاملOptimal Selection of Addendum Modification Coefficients of Involute Cylindrical Gears
Based on the principles of equalized sliding coefficients and equalized teeth bending strength, the optimization mathematical model for calculating and allocating the addendum modification coefficients of involute cylindrical gear is firstly established. Then the measures to calculate the tooth parameters in real-time during the optimization steps are achieved. Finally, the optimization program...
