Igor Mordatch, Kendall Lowrey, Galen Andrew, Zoran Popovic, Emanuel Todorov
2015 Neural Information Processing Systems  
We present a method for training recurrent neural networks to act as near-optimal feedback controllers.  ...  The controller is a neural network, having a large number of feed-forward units that learn elaborate state-action mappings, and a small number of recurrent units that implement memory states beyond the  ...  Conclusions and Future Work We have presented an automatic way of generating neural network parameters that represent a control policy for physically consistent interactive character control, only requiring  ...

Neural MoCon: Neural Motion Control for Physically Plausible Human Motion Capture [article]

Buzhen Huang, Liang Pan, Yuan Yang, Jingyi Ju, Yangang Wang
2022 arXiv   pre-print
Qualitative and quantitative results show that we can obtain physically plausible human motion with complex terrain interactions, human shape variations, and diverse behaviors.  ...  Finally, we regress the sampling distribution from the current state of the physical character with the trained prior and sample satisfied target poses to track the estimated reference motion.  ...  In addition, with the sampling, the neural motion control is more general to complex terrain, body shape variations, and diverse behaviors.  ...

Recognition and Generation of Sentences through Self-organizing Linguistic Hierarchy Using MTRNN [chapter]

Wataru Hinoshita, Hiroaki Arie, Jun Tani, Tetsuya Ogata, Hiroshi G. Okuno
2010 Lecture Notes in Computer Science  
These studies have found that some kinds of recurrent neural networks could learn grammar.  ...  We show that a Multiple Timescale Recurrent Neural Network (MTRNN) can acquire the capabilities of recognizing and generating sentences by self-organizing a hierarchical linguistic structure.  ...  This capability is essential for dealing with the diversity of expressions in language. Thus, it is also important to find whether a neural system can acquire such hierarchical structures.  ...

Neuroevolution: from architectures to learning

Dario Floreano, Peter Dürr, Claudio Mattiussi
2008 Evolutionary Intelligence  
Artificial neural networks (ANNs) are applied to many real-world problems, ranging from pattern classification to robot control.  ...  In order to design a neural network for a particular task, the choice of an architecture (including the choice of a neuron model), and the choice of a learning algorithm have to be addressed.  ...  Their results indicate that for tasks with memory dependent dynamics, spiking neural networks can provide less complex solutions.  ...
