It made use of the short-term memory ability of the recurrent weights to store spatio-temporal sequences features, while the attached parametric bias units were trained in a self-organizing way and represented as a low-dimensional expression space to capture these non-linear features of the sequences. Three demonstrations were given: training and recognition performances were examined in computer simulations, while the network generated both trained and novel movements were shown in a three-dimensional avatar demonstrations.}, doi = {10.1109/DEVLRN.2014.6982957}, url = {http://ieeexplore.ieee.org/document/6982957/}, author = {Junpei Zhong and Lola Ca{\~n}amero} } @inproceedings {2008, title = {Towards a Hormone-Modulated Model for Emotion Expression in a Socially Interactive Robot Head}, booktitle = {Workshop "The role of Emotion in Adaptive Behavior and Cognitive Robotics" held in conjunction with 10th International Conference on Simulation of Adaptive Behavior (SAB 2008)}, year = {2008}, month = {07/2008}, address = {Osaka, Japan}, abstract = {In this paper we present a robot head ERWIN capable of human-robot interaction, endowed with interactive mechanisms for allowing the emotional state and expression of the robot to be directly influenced by the social interaction process. Allowing the interaction process to influence the expression of the robot head can in turn influence the way the user interacts with the robot, in addition to allowing the user to better understand the intentions of the robot during this process. We discuss some of the interactions that are possible with ERWIN and how this can affect the response of the system. We show an example scenario where the interaction process makes the robot go through several different emotions.}, url = {http://image.ece.ntua.gr/projects/feelix/system/files/Murray_SAB_final-1.pdf}, author = {John C Murray and Lola Ca{\~n}amero}, editor = {Robert Lowe and Morse, A and Ziemke, T} } @inproceedings {2003, title = {Analyzing the Performance of "Winner-Take-All" and "Voting-Based" Action Selection Policies within the Two-Resource Problem}, booktitle = {Advances in Artificial Life: 7th European Conference, ECAL 2003}, series = {Lecture Notes in Artificial Intelligence}, volume = {2801}, year = {2003}, note = {Download}, month = {09/2003}, pages = {733{\textendash}742}, publisher = {Springer}, organization = {Springer}, address = {Dortmund, Germany}, abstract = {The problem of action selection for an autonomous creature implies resolving conflicts between competing behavioral alternatives. These conflicts can be resolved either via competition, following a {\textquotedblleft}winner-take-all{\textquotedblright} approach, or via cooperation in a {\textquotedblleft}voting-based{\textquotedblright} approach. In this paper we present two robotic architectures implementing these approaches, and report on experiments we have performed to compare their underlying optimization policies.
