Temporal sequence learning, prediction, and control: a review of different models and their relation to biological mechanisms

F Wörgötter, B Porr - Neural computation, 2005 - ieeexplore.ieee.org
In this review, we compare methods for temporal sequence learning (TSL) across the disciplines
machine-control, classical conditioning, neuronal models for TSL as well as spike-timing…

Fast biped walking with a sensor-driven neuronal controller and real-time online learning

T Geng, B Porr, F Wörgötter - The International Journal of …, 2006 - journals.sagepub.com
In this paper, we present our design and experiments on a planar biped robot under the control
of a pure sensor-driven controller. This design has some special mechanical features, for …

[HTML][HTML] Adaptive, fast walking in a biped robot under neuronal control and learning

…, T Geng, T Kulvicius, B Porr… - PLoS Computational …, 2007 - journals.plos.org
Human walking is a dynamic, partly self-stabilizing process relying on the interaction of the
biomechanical design with its neuronal control. The coordination of this process is a very …

[HTML][HTML] Reinforcement learning

F Woergoetter, B Porr - Scholarpedia, 2008 - var.scholarpedia.org
Reinforcement learning (RL) is learning by interacting with an environment. An RL agent
learns from the consequences of its actions, rather than from being explicitly taught and it …

Cognitive agents—a procedural perspective relying on the predictability of Object-Action-Complexes (OACs)

…, A Agostini, N Krüger, N Shylo, B Porr - Robotics and Autonomous …, 2009 - Elsevier
Embodied cognition suggests that complex cognitive traits can only arise when agents have
a body situated in the world. The aspects of embodiment and situatedness are being …

Isotropic sequence order learning

B Porr, F Wörgötter - Neural Computation, 2003 - direct.mit.edu
In this article, we present an isotropic unsupervised algorithm for temporal sequence learning.
No special reward signal is used such that all inputs are completely isotropic. All input …

Strongly improved stability and faster convergence of temporal sequence learning by using input correlations only

B Porr, F Wörgötter - Neural computation, 2006 - direct.mit.edu
Currently all important, low-level, unsupervised network learning algorithms follow the
paradigm of Hebb, where input and output activity are correlated to change the connection …

How the shape of pre-and postsynaptic signals can influence STDP: a biophysical model

A Saudargiene, B Porr, F Wörgötter - Neural Computation, 2004 - ieeexplore.ieee.org
Spike-timing-dependent plasticity (STDP) is described by long-term potentiation (LTP),
when a presynaptic event precedes a postsynaptic event, and by long-term depression (LTD), …

[HTML][HTML] R-peak detector stress test with a new noisy ECG database reveals significant performance differences amongst popular detectors

B Porr, L Howell - BioRxiv, 2019 - biorxiv.org
The R peak detection of an ECG signal is the basis of virtually any further processing and
any error caused by this detection will propagate to further processing stages. Despite this, R …

SaBer DBS: a fully programmable, rechargeable, bilateral, charge-balanced preclinical microstimulator for long-term neural stimulation

SG Ewing, B Porr, J Riddell, C Winter… - Journal of neuroscience …, 2013 - Elsevier
To effectively study the mechanisms by which deep brain stimulation (DBS) produces its
therapeutic benefit and to evaluate new therapeutic indications, it is vital to administer DBS over …
