Causal Learning by a Robot with Semantic-Episodic Memory in an Aesop's Fable Experiment [article]

Ajaz A. Bhat, Vishwanathan Mohan
2020 arXiv   pre-print
We address this question by re-enacting the Aesop's Fable task on a robot and present a) a brain-guided neural model of semantic-episodic memory; with b) four task-agnostic learning rules that compare  ...  expectations from recalled past episodes with the current scenario to progressively extract the hidden causal relations.  ...  While the former relates to the motor affordance of an object, the latter relates to motion planning details, and interested reader may refer to Bhat et al. (2017) for details related to motion planning  ...

Changes in balance coordination and transfer to an unlearned balance task after slackline training: a self-organizing map analysis

Ben Serrien, Erich Hohenauer, Ron Clijsen, Wolfgang Taube, Jean-Pierre Baeyens, Ursula Küng
2017 Experimental Brain Research  
The SOM analysis, followed by a k-means clustering and marginal homogeneity test, showed that the balance coordination pattern was significantly different between pre-and post-test for the slackline task  ...  The shift in balance coordination on the slackline could be characterized by an increase in range of motion and a decrease in velocity and frequency in nearly all degrees of freedom simultaneously.  ...  Compliance with ethical standards Conflict of interest All authors declare that they have no conflict of interest that may have biased the findings in this article.  ...
