Coordinated Reinforcement Learning

We present several new algorithms for multiagent reinforcement learning. A common feature of these algorithms is a parameterized, structured representation of a policy or value function. This structure is leveraged in an approach we call coordinated reinforcement learning, by which agents coordinate both their action selection activities and their parameter updates. Within the limits of our par...

Efficient Deep Web Crawling Using Reinforcement Learning

Deep web refers to the hidden part of the Web that remains unavailable for standard Web crawlers. To obtain content of Deep Web is challenging and has been acknowledged as a significant gap in the coverage of search engines. To this end, the paper proposes a novel deep web crawling framework based on reinforcement learning, in which the crawler is regarded as an agent and deep web database as t...

Coordinated Exploration in Concurrent Reinforcement Learning

We consider a team of reinforcement learning agents that concurrently learn to operate in a common environment. We identify three properties – adaptivity, commitment, and diversity – which are necessary for efficient coordinated exploration and demonstrate that straightforward extensions to single-agent optimistic and posterior sampling approaches fail to satisfy them. As an alternative, we pro...

Reinforcement Learning for Coordinated Reactive Control

The demands of rapid response and the complexity of many environments make it diicult to decompose, tune and coordinate reactive behaviors while ensuring consistency. Reinforcement learning networks can address the tuning problem, but do not address the problem of decomposition and coordination. We hypothesize that interacting reactions can often be decomposed into separate control tasks reside...

FICA: A novel intelligent crawling algorithm based on reinforcement learning

The web is a huge and highly dynamic environment which is growing exponentially in content and developing fast in structure. No search engine can cover the whole web, thus it has to focus on the most valuable pages for crawling. So an efficient crawling algorithm for retrieving the most important pages remains a challenging issue. Several algorithms like PageRank and OPIC have been proposed. Un...
