Digital libraries and search engines are now well-equipped to find images of documents based on queries. Many images of music scores are now available, often mixed up with textual documents and images. For example, using the Google “images” search feature, a search for “Beethoven” will return a number of scores and manuscripts as well as pictures of the composer. In this paper we report on an i...

HIGHLIGHTS Pollen grains of ten sunflower inbred lines were evaluated under normal and high temperature stress conditions. Two treatments three treatment times used as factors viability, pollen germination percentage tube length decreased with increasing time period. RL-86 ORI-73 showed excellent ability to withstand stress.

There is surmounting evidence that reinforcement learning (RL) is a good model for the dopamine system of the brain and the prefrontal cortex. RL is also promising from the algorithmic point of view, because recent factored RL algorithms have favorable convergence and scaling properties and can counteract the curse of dimensionality problem, the major obstacle of practical applications of RL me...

Reinforcement learning (RL) problems come in many flavours, as do algorithms for solving them. It is currently not clear which of the commonly used RL benchmarks best measure an algorithm’s capacity for solving real-world problems. Similarly, it is not clear which types of RL algorithms are best suited to solve which kinds of RL problems. Here we present some dimensions along the axes of which ...

In this paper we present a reinforcement learning (RL) system based on neural circuits. The neural RL system is benchmarked against a Monte Carlo (MC) RL algorithm on two tasks. The first task is the classical n-armed bandit problem and the second task is path finding in a maze. The neural RL system performs equally well or better than the MC RL algorithm. The RL system presented is very flexib...

We define shell l in a network as the set of nodes at distance l with respect to a given node and define rl as the fraction of nodes outside shell l . In a transport process, information or disease usually diffuses from a random node and reach nodes shell after shell. Thus, understanding the shell structure is crucial for the study of the transport property of networks. We study the statistical...

Spoken dialogue systems typically do not manage the communication channel, instead using fixed values for such features as the amplitude and speaking rate. Yet, the quality of a dialogue can be compromised if the user has difficulty understanding the system. In this proof-of-concept research, we explore using reinforcement learning (RL) to create policies that manage the communication channel t...
