Many machine learning approaches in robotics, based on reinforcement learning, inverse optimal control or direct policy learning, critically rely on robot simulators. This paper investigates a simulatorfree direct policy learning, called Preference-based Policy Learning (PPL). PPL iterates a four-step process: the robot demonstrates a candidate policy; the expert ranks this policy comparatively...

Many potential applications for agent technology require humans and agents to work together to achieve complex tasks effectively. In contrast, most of the work in the agents community to date has focused on technologies for fully autonomous agent systems. This paper presents a framework for the directability of agents, in which a human supervisor can define policies to influence agent activitie...

as putin regained the power in russia, the situation gave a second chance to this country to avoid both the west and the benefits of convergence with its foreign policy and regional and trans-regional equations. this can take advantages from other side. approach of russia to divergence and independence with the west will increase level of russian hegemony on international arena. the main questi...

This paper aims to investigate the role of each aggregate spending component in the monetary policy transmission in Indonesia. It assesses the relative strength of the role of each spending component in the monetary policy transmission. In so doing, this study employs the contribution analysis, which is calculated based on the cumulative impulse response of each component of GDP to a monetary p...

As energy models become more and powerful, they are increasingly used to support policymaking. Although modelling has been for policy advice many years, there is little knowledge about how computer-based actually influence policymaking, what extent policymakers the process. Here, we empirically investigate (i) whether, when policymaking process, (ii) design, use results of modelling. We analyse...

in literature about inflation targeting, main factor is interest rate. in new surveys, price of some assets as housing is important in inflation targeting. iran inflation targeting is based on money changes and is not based on interest rate and housing price. in this paper, we want to survey problems of wrong policy of iran policy makers. we reveal that, using rate of deposit profit and growth ...

this paper presents a new formulation for warehouse inventory management in a stochastic situation. the primary source of this formulation is derived from fp model, which has been proposed by fletcher and ponnambalam for reservoir management. the new proposed mathematical model is based on the first and the second moments of storage as a stochastic variable. using this model, the expected value...

the acceptance of the right project which leads to the realization of the set objectives is one of the most important issues in project-oriented companies. therefore, corporate managers prefer to work on those projects which ensures the achievement of goals such as increasing financial profits or being the top brands in their rivals market. the present  research aimed at introducing  a systemat...
