Event-based decision process (EDP) has provided a general framework for many event-based control, decision making, and optimization problems. Since the number of events could increase only linearly w.r.t. the system scale, EDP provides a computationally feasible way for many problems, which are time-consuming to solve in the Markov decision process (MDP) framework. Because the event sequence usually is not Markovian, policies that only depend on the current observable event usually are not optimal. In this paper, we develop a rollout method for finite-stage EDP, which uses simulation under a base policy to estimate the performances of action candidates. We show that this leads to a policy better than the base policy. This rollout method is easy to implement. The advantage is also demonstrated through a node activation policy optimization problem in wireless sensor network.

This paper introduces an interactive method to design intuitive and simple surface appearance of 3D computer graphics shapes. Texture mapping is widely used to improve the visual richness of 3D surfaces. Designing texture patterns can be a technique to search a pattern which is adequate for the target 3D shapes in the specific scene physically and psychologically. We apply Interactive Evolutionary Computation (IEC) framework to find the pleasant color texture pattern for 3D surfaces. This method generates multiple texture patterns obtained by various image processing and allows users to evaluate them sensitively.
In this paper, we present an unconstrained visual gaze estimation system. The proposed method extracts the visual field of view of a person looking at a target scene in order to estimate the approximate location of in...
