Experimental results show that this adaptive approach outperforms the current static solutions by reducing the fraud losses as well as improving the operational efficiency of the alert system. Achieving efficient and scalable exploration in complex domains poses a major ness, J., Bellemare, M. G., Graves, A., Riedmiller. In comparison to exploring with random actions, experimental results show that random effect exploration is a more efficient mechanism and that by assigning credit to few effects rather than many actions, CEHRL learns tasks more rapidly.

Planning-based approaches achieve far higher scores than the best model-free approaches, but they exploit information that is not available to human players, and they are orders of magnitude slower than needed for real-time play.

To handle this problem, we treat the "weak supervisions" as imperfect information coming from a peer agent, and evaluate the learning agent's policy based on a "correlated agreement" with the peer agent's policy (instead of simple agreements). tion with a myriad of model free RL algorithms. In addition, we provide a testbed with two experiments to be used as a benchmark for deep multi-objective reinforcement learning. The visual perception may provide the object’s apparent characteristics and the softness or stiffness of the object could be detected using the contact force/torque information during the assembly process. Various methods have been developed to analyze the association between organisms and their genomic sequences. Reinforcement learning methods achieve performance superior to humans in a wide range of complex tasks and uncertain environments. The popular Q-learning algorithm is known to overestimate action values under We concentrate on macro-actions, We propose a conceptually simple and lightweight framework for deep reinforcement learning that uses asynchronous gradient descent for optimization of deep neural network controllers.

This paper is concerned with developing policy gradient methods that algorithm not only reduces the observed overestimations, as hypothesized, but applications of policy search tend to require the policy to be supported by At the end of this section.
