A Learning Based Vision Guided Robotic Agent Replanning Framework and a Case Study
نویسنده
چکیده
In this paper, a replanning framework and a case study based on our learning based robotic replanning framework that can handle unexpected events in dynamic worlds are presented. This study presents an original replanning method which uses an alternative based action selection mechanism to select the most efficient action path among possible alternative action paths. The method stores the costs of actions paths from previous executions as an experience and uses it for improving its future action selection decisions. The fact that a continous vision feedback is supplied to the symbolic planning level (highest level of abstraction) is also a contribution of this study since this way, the architecture detects the presence of unexpected events, generates an updated model of the environment and discards or modifies the existing obsolete action path in case of an unexpected event(s).

Organizational Learning and Knowledge Spillover in Innovation Networks: Agent-Based Approach (Extending SKIN Framework)
In knowledge-based economy, knowledge has a public good and non-rivalry nature. Firms build their own knowledge stock not only by means of internal R&D and collaboration with partners, but also by means of previously spilled over knowledge of other firms and public research laboratories (such as universities). Firms based on their absorptive capacity, and level of intra-industry and extra-indus...
متن کاملUtilizing Generalized Learning Automata for Finding Optimal Policies in MMDPs
Multi agent Markov decision processes (MMDPs), as the generalization of Markov decision processes to the multi agent case, have long been used for modeling multi agent system and are used as a suitable framework for Multi agent Reinforcement Learning. In this paper, a generalized learning automata based algorithm for finding optimal policies in MMDP is proposed. In the proposed algorithm, MMDP ...
متن کاملRobotic Vision System Based on Intelligent Agents
This paper presents a robotic vision mechanism based on a multiagent robotic system for controlling the behaviour of the agents. In this approach, we used the fuzzy technology which is very adequate in this study case. The combined mechanisms offer surveillance of the entire set of robots and contribute to an appropriate behaviour for them.
متن کاملImproving Agent Performance for Multi-Resource Negotiation Using Learning Automata and Case-Based Reasoning
In electronic commerce markets, agents often should acquire multiple resources to fulfil a high-level task. In order to attain such resources they need to compete with each other. In multi-agent environments, in which competition is involved, negotiation would be an interaction between agents in order to reach an agreement on resource allocation and to be coordinated with each other. In recent ...
متن کاملA Case-Based Approach To Imitation Learning in Robotic Agents
Learning by imitation is an essential process in human cognition. Recently, imitation learning has also become important in robotics research. We address the problem of learning by imitation in interactive, robotic agents using case-based reasoning. We describe two tasks for which case-based reasoning may be used: (i) interpretation, in which the robot interprets new skill demonstrations as bei...
