Deep learning discovers intricate structure in large data sets by using the backpropagation algorithm to indicate how a machine should change its internal parameters that are used to compute the representation in each layer from the representation in the previous layer. Dueling Network Architectures for Deep Reinforcement Learning Nando de Freitas , Marc Lanctot , Hado van Hasselt , Matteo Hessel , Tom Schaul , Ziyu Wang - 2015 Paper Links : Full-Text An environment cannot be effectively described with a single perception form in skill learning for robotic assembly. Among them, sequence alignment is the most frequently used for comparative analysis of biological genomes. Our dueling network represents two separate estimators: one for the state value function and one for the state-dependent action advantage function. ness, J., Bellemare, M. G., Graves, A., Riedmiller. However, this approach simply replays of non-linear dynamical systems from raw pixel images. This ability can however be very useful as originally presented in, ... Then, the features derived from the LSTM layer are concatenated with the embedded vector of ID, which results in distinguishing each agent implicitly and encourage diverse behavior. stored experience; a distributed neural network to represent the value function (2013). For an environment with reward saltation, we propose a magnify saltatory reward (MSR) algorithm with variable parameters from the perspective of sample usage.
