Many real-world tasks involve multiple agents with partial observability and limited communication. Learning is challenging in these settings due to local viewpoints of agents, which perceive the world as non-stationary due to concurrentlyexploring teammates. Approaches that learn specialized policies for individual tasks face problems when applied to the real world: not only do agents have to ...

The purpose of this paper is to describe the testing of a new scale to assess the perceived attributes of a federal drug prevention policy. The 17-item scale was administered to 107 Safe and Drug Free Schools (SDFS) coordinators in 12 states as a part of a larger investigation examining the diffusion of a federal drug prevention policy. In developing this scale, the authors drew from theory, pr...

We consider the partial observability model for multi-armed bandits, introducedby Mannor and Shamir [11]. Our main result is a characterization of regret inthe directed observability model in terms of the dominating and independencenumbers of the observability graph. We also show that in the undirected case, thelearner can achieve optimal regret without even accessing the observ...

Several concepts on the measure of observability, reachability, and robustness are defined and illustrated for both linear and nonlinear control systems. Defined by using computational dynamic optimization, these concepts are applicable to a wide spectrum of problems. Some questions addressed include the observability based on userinformation, the determination of strong observability vs. weak ...

Infinite–dimensional linear dynamic systems, with output, are studied. They are described by row-finite infinite matrices. Observability of such systems is investigated. It is shown that observability is equivalent to the property that one can calculate the value of each state variable using only finitely many rows of Kalman observability matrix. Different necessary or sufficient conditions of ...

Reachability and observability criteria are obtained for 2D continuous-discrete time-variable Attasi type systems by using suitable 2D reachability and observability Gramians. Necessary and sufficient conditions of reachability and observability are derived for time-invariant systems. The duality between the two concepts is emphasized as well as their connection with the minimality of these sys...

Positive reachability and positive observability of positive linear systems on time scales are studied. Differential and integral calculus on time scales allows for unified treatment of continuousand discrete-time systems. Reachability and observability graphs for positive systems are introduced. They are used to characterize positive reachability and positive observability for systems on homog...

Rice is a staple food for Indonesian people, but the loss of crop yields still relatively high. The can be reduced by making improvements to application technology. Technological innovation in agriculture increase agricultural productivity. process accepting technological defined as adoption. Farmer’s adoption technology determined characteristic innovation, including relative advantage, compat...
