Reasoning about shadows in a mobile robot environment
(2013)
This paper describes a logic-based formalism for qualitative spatial reasoning with cast shadows (Perceptual Qualitative Relations on Shadows, or PQRS) and presents results of a mobile robot qualitative self-localisation ...
Reasoning about depth and motion from an observer's viewpoint
(2007)
The goal of this paper is to present a logic-based formalism for representing knowledge about objects in space and their movements, and show how this knowledge could be built up from the viewpoint of an observer immersed ...
Heuristically Accelerated Reinforcement Learning by Means of Case-Based Reasoning and Transfer Learning
(2018)
© 2017, Springer Science+Business Media B.V.Reinforcement Learning (RL) is a well-known technique for learning the solutions of control problems from the interactions of an agent in its domain. However, RL is known to be ...
Formalising the fisherman's folly puzzle
(2011)
This paper investigates the challenging problem of encoding the common sense knowledge involved in the manipulation of spatial objects from a reasoning about actions and change perspective. In particular, we propose a ...
Transferring knowledge as heuristics in reinforcement learning: A case-based approach
(2015)
© 2015 Elsevier B.V.Abstract The goal of this paper is to propose and analyse a transfer learning meta-algorithm that allows the implementation of distinct methods using heuristics to accelerate a Reinforcement Learning ...
Protocols from perceptual observations
(2005)
This paper presents a cognitive vision system capable of autonomously learning protocols from perceptual observations of dynamic scenes. The work is motivated by the aim of creating a synthetic agent that can observe a ...
The space within fisherman's folly: Playing with a puzzle in mereotopology
(2008)
In this paper we propose a spatial ontology for reasoning about holes, rigid objects and a string, taking a classical puzzle as a motivating example. In this ontology the domain is composed of spatial regions whereby a ...
The perception and content of cast shadows: An interdisciplinary review
(2011)
Recently, psychologists have turned their attention to the study of cast shadows and demonstrated that the human perceptual system values information from shadows very highly in the perception of spatial qualities, sometimes ...
