Developing Affect-Modulated Behaviors: Stability, Exploration, Exploitation or Imitation?
Exploring the environment is essential for autonomous agents to learn new things and to consolidate past experiences and apply them to improve behavior. However, exploration is also risky as it exposes the agent to unknown, potentially overwhelming or dangerous situations. A trade-off must hence exist between activities such as seeking stability, autonomous exploration of the environment, imita...
متن کاملBiasing Neural Networks Towards Exploration or Exploitation Using Neuromodulation
Taking neuromodulation as a mechanism underlying emotions, this paper investigates how such a mechanism can bias an artificial neural network towards exploration of new courses of action, as seems to be the case in positive emotions, or exploitation of known possibilities, as in negative emotions such as predatory fear. We use neural networks of spiking leaky integrate-and-fire neurons acting a...
متن کاملGroup-Level Exploration and Exploitation
Organisational research has studied the tension between exploration and exploitation for years. In essence, this body of research agrees on the necessity of a balance between explorative and exploitative processes to prevent an organisation from falling into a learning trap. Thus, to enhance the active management of this balance in organisations, a deeper theoretical understanding of the factor...
متن کاملOn Evolutionary Exploration and Exploitation
Exploration and exploitation are the two cornerstones of problem solving by search. The common opinion about evolutionary algorithms is that they explore the search space by the (genetic) search operators, while exploitation is done by selection. This opinion is, however, questionable. In this paper we give a survey of diierent operators, review existing viewpoints on exploration and exploitati...
متن کاملExploration / Exploitation in Adaptive Recommender
Interactive information systems are often designed on the basis of little knowledge about users goals and about the final content of the information base. In addition users vary widely in their interests. This makes it useful to give such systems the ability to dynamically adapt to its users. Here we focus on ”recommending” systems that help a user navigate through the information system. In pa...
