This work describes a robot visual homing model that employs, for the first time, the conjugate gradient Temporal Difference (TD-conj) method. TD-conj was proved to be equivalent to a gradient TD method with a variable λ, denoted as (TD(λt(conj))), when both are used with function approximation techniques. This fact is employed in the model to improve its performance. Based on visual input that is...
Topological maps are used by biological species for navigation in complex and cluttered environments with very primitive sensory inputs and limited computational abilities. The core aspect of topological maps are the properties (usually some environmental features) used to define the nodes of the map. In this paper we use a well known technique adopted by desert ants called visual piloting for autonomous...
