Online representational expansion techniques have improved the learning speed of existing reinforcement learning (RL) algorithms in low dimensional domains, yet existing online expansion methods do not scale well to high dimensional problems. We conjecture that one of the main difficulties limiting this scaling is that features defined over the full-dimensional state space often generalize poor...

The objectives in the cold rolling process include improved sheet surface quality, enhanced steel mechanical strength, and better solidification operations. Given the increasing demand for higher steel...

In this paper, we propose a method of designing low-dimensional retrofit controllers for interconnected linear systems. In the proposed method, by retrofitting an additional low-dimensional controller to a preexisting control system, we aim at improving transient responses caused by spatially local state deflections, which can be regarded as a local fault occurring at a specific subsystem. It i...

In this article, we apply the improved (G′/G)-expansion method to construct some new exact traveling wave solutions including soliton and periodic solutions of the combined KdV-MKdV equation involving parameters. In this method, G′′+λG′+μG = 0 together with ( ) ( ) j m

Various methods to recognize assembly tasks using possible local displacement of objects have been proposed. To calculate this displacement, the screw theory is employed. It is equivalent to the first order Taylor expansion of the displacement. However, such methods can treat polyhedral objects only. Because the screw theory cannot treat curvature information of objects. In this paper, we propo...

We discuss the Taylor expansion approach to non-zero baryon chemical potential (μB) and present results on expanion coefficients of the pressure and energy density up to the 6-th order in μB. Calculations have been performed with (2+1)-flavor of improved staggerd fermions (p4fat3) and almost physical masses on lattices with temporal extent of four and six time slices. We use the expansion coeff...
