Pricing credit derivatives under incomplete information: a nonlinear-filtering approach
This paper considers a general reduced form pricing model for credit derivatives where default intensities are driven by some factor process X. The process X is not directly observ...

Observed Lower Bounds for Random 3-SAT Phase Transition Density Using Linear Programming
We introduce two incomplete polynomial time algorithms to solve satisfiability problems which both use Linear Programming (LP) techniques. First, the FlipFlop LP attempts to simul...

Laser tracking of human body motion using adaptive shape modeling
— In this paper we present a method for determining body orientation and pose information from laser scanner data using particle filtering with an adaptive modeling algorithm. A...

Three-Valued 9-Intersection for Deriving Possible Topological Relations from Incomplete Observations
Topological relations, which concern how two objects intersect, are one of the most fundamental and well-studied spatial relations. Typically, topological relations are distinguis...
