Epi is a humanoid robot developed by Lund University Cognitive Science Robotics Group. It
was designed to be used in experiments in developmental robotics and has proportions to …

Computational models of emotions for autonomous agents: major challenges

LF Rodríguez, F Ramos - Artificial Intelligence Review, 2015 - Springer
A great number of computational models of emotions (CMEs) have been developed to be
included in, or as part of, cognitive agent architectures. These computational models have …

First and second order dynamics in a hierarchical SOM system for action recognition

Z Gharaee, P Gärdenfors, M Johnsson - Applied Soft Computing, 2017 - Elsevier
Human recognition of the actions of other humans is very efficient and is based on patterns
of movements. Our theoretical starting point is that the dynamics of the joint movements is …

Sense of touch in robots with self-organizing maps

M Johnsson, C Balkenius - IEEE Transactions on Robotics, 2011 - ieeexplore.ieee.org
We review a number of self-organizing-robot systems that are able to extract features from
haptic sensory information. They are all based on self-organizing maps (SOMs). First, we …

A computational model of pupil dilation

B Johansson, C Balkenius - Connection Science, 2018 - Taylor & Francis
We present a system-level connectionist model of pupil control that includes brain regions
believed to influence the size of the pupil. It includes parts of the sympathetic and …

Myon, a new humanoid

M Hild, T Siedel, C Benckendorff, C Thiele… - Language grounding in …, 2012 - Springer
This chapter introduces the modular humanoid robot Myon, covering its mechatronical
design, embedded low-level software, distributed processing architecture, and the …

Associative self-organizing map

M Johnsson, C Balkenius, G Hesslow - International Conference on …, 2009 - scitepress.org
We present a study of a novel variant of the Self-Organizing Map (SOM) called the
Associative Self-Organizing Map (A-SOM). The A-SOM is similar to the SOM and thus …

The missing link between memory and reinforcement learning

C Balkenius, TA Tjøstheim, B Johansson… - Frontiers in …, 2020 - frontiersin.org
Reinforcement learning systems usually assume that a value function is defined over all
states (or state-action pairs) that can immediately give the value of a particular state or …

Hierarchies of self-organizing maps for action recognition

M Buonamente, H Dindo, M Johnsson - Cognitive Systems Research, 2016 - Elsevier
We propose a hierarchical neural architecture able to recognise observed human actions.
Each layer in the architecture represents increasingly complex human activity features. The …

A computational model of trust-, pupil-, and motivation dynamics

TA Tjøstheim, B Johansson, C Balkenius - Proceedings of the 7th …, 2019 - dl.acm.org
Autonomous machines are in the near future likely to increasingly interact with humans, and
carry out their functions outside controlled settings. Both of these developments increase the …
