Gradient-following algorithms are deployed for efficient adaptation of exploration parameters in temporal-difference learning with discrete action spaces. Global and local variants are evaluated in discrete and continuous state spaces. The global variant is memory efficient in terms of requiring exploratory data only for starting states. In contrast, the local variant requires exploratory data ...

Haptic exploration with robotic ngers is accomplished by feature-guided exploration, where information about surface features such as cracks and ridges is used to guide the nger in an exploratory procedure. A local exploration strategy uses contact trajectory information from a tactile sensor to identify features while moving over and around them. Using an algorithm based on the Voronoi diagram...

taknar deposit is located about 28 km to the north-west of bardaskan in the khorasan-e-razavi province, which is situated in the north-eastern part of iran. this deposit is unique, formed within the taknar formation in the ordovician time. as a result, it is of much interest to many researchers working in this field. by choosing the lithogeochemical study performed to recognize new exploration ...

Efficient robotic exploration of an unknown, sensor limited, global-information-deficient environments poses unique challenges to path planning algorithms. In these difficult environments, no deterministic guarantees on path completion and mission success can be made in general. Integrated Exploration (IE), which strives to combine localization and exploration, must be solved in order to create...

Our civilization is based on metals, among other life supports. The existing ore deposits are becoming rapidly depleted by almost exponentially increasing demand and production and major new ore discoveries are needed. Mineral exploration is supported by modern tools and scientific ideas, but geological characteristics of orebodies and their rock associations have still to be visualized.The tim...

Network reconfiguration is a nonlinear optimization procedure which calculates a radial structure to optimize the power losses and improve the network reliability index while meeting practical constraints. In this paper, a multi-objective framework is proposed for optimal network reconfiguration with the objective functions of minimization of power losses and improvement of reliability index. T...
