EchoRob: Echo State Networks for Developing Language Robots
EchoRob is a research project developed in the Knowledge Technology group of Hamburg University funded by the Marie Curie IEF programme between March 2015 and February 2016.

Associates: J. Twiefel, Dr. S. Magg
Here, we propose to develop the Reservoir Computing (RC) paradigm — in particular Echo State Networks (ESN) with incremental learning — to model language comprehension at the sentence level given sequential inputs of words or phonemes. Based on our initial research, a model processing syntactic sentence structures was able to demonstrate generalisation and online prediction capabilities while processing sequential input.
For less frequent inputs, the model provided potential explanation for human electrophysiological data. Building on this research, a new model is proposed with the following objectives:
On Saturday 7 November 2015, Dr. X. Hinaut and J. Twiefel participated at the 6th Nacht des Wissens (Night of Science) in Hamburg. At their booth, they showed a demo with a Nao humanoid robot talking to visitors. They also showed a video explaining how a robot learns to name objects based on Convolutional Neural Networks, the DOCKS system and the sentence comprehension model central to the EchoRob project. Several motivated Bachelor and Master students helped as well to explain to numerous visitors how the whole system works (in German and English).
