TY - CONF T1 - From Continuous Affective Space to Continuous Expression Space: Non-Verbal Behaviour Recognition and Generation T2 - Proc. 4th Joint IEEE International Conference on Development and Learning and on Epigenetic Robotics (ICDL-Epirob 2014) Y1 - 2014 A1 - Junpei Zhong A1 - Lola Cañamero AB - In this research, a recurrent neural network with parametric bias (RNNPB) was adopted to construct a continuous expression space from emotion caused human behaviours. 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.

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.

These conflicts can be resolved either via competition, following a “winner-take-all” approach, or via cooperation in a “voting-based” 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. We have framed this study within the context of the “two-resource problem,” as it provides a widely used standard that favors systematic experimentation, analysis, and comparison of results.
