Benefits and limitations of a new hydraulic performance model

no code implementations28 Jul 2022 Fabian C. Weigend, Edward Gray, Oliver Obst, Jason Siegler

In this work, we hypothesised that the benefits of the model come at the cost of inaccurate predictions of metabolic responses to exercise such as $\dot{V}_{\mathrm{O}_2}$.

Analyzing Echo-state Networks Using Fractal Dimension

no code implementations19 May 2022 Norbert Michael Mayer, Oliver Obst

This connection between fractal dimension and network connectivity is an interesting new direction for recurrent neural network initialization and reservoir computing.

A Systematic Literature Review of Automated ICD Coding and Classification Systems using Discharge Summaries

1 code implementation12 Jul 2021 Rajvir Kaur, Jeewani Anupama Ginige, Oliver Obst

Efforts are still required to improve ICD code prediction accuracy, availability of large-scale de-identified clinical corpora with the latest version of the classification system.

A New Pathway to Approximate Energy Expenditure and Recovery of an Athlete

1 code implementation16 Apr 2021 Fabian Clemens Weigend, Jason Siegler, Oliver Obst

This work proposes to use evolutionary computation as a pathway to allow a new perspective on the modeling of energy expenditure and recovery of an individual athlete during exercise.

Information Maximizing Exploration with a Latent Dynamics Model

no code implementations4 Apr 2018 Trevor Barron, Oliver Obst, Heni Ben Amor

A key insight of our approach is that this dynamics model can be learned in the latent feature space of a value function, representing the dynamics of the agent and the environment.

RoboCupSimData: A RoboCup soccer research dataset

1 code implementation6 Nov 2017 Olivia Michael, Oliver Obst, Falk Schmidsberger, Frieder Stolzenburg

These data are made available as CSV files, as well as in the original soccer simulator formats.

Analysing Soccer Games with Clustering and Conceptors

no code implementations19 Aug 2017 Olivia Michael, Oliver Obst, Falk Schmidsberger, Frieder Stolzenburg

With the proposed approach, we can segment games into sequences of situations that are learnt in an unsupervised way, and learn conceptors that are useful for the prediction of the near future of the respective situation.

Simulation leagues: Analysis of competition formats

no code implementations17 Mar 2014 David Budden, Peter Wang, Oliver Obst, Mikhail Prokopenko

A proposed new competition format is found to reduce variation from the resultant statistically significant team performance rankings by 75% and 67%, when compared to the actual competition results from RoboCup 2012 and 2013 respectively.

Nano-scale reservoir computing

no code implementations6 Sep 2013 Oliver Obst, Adrian Trinchi, Simon G. Hardin, Matthew Chadwick, Ivan Cole, Tim H. Muster, Nigel Hoschke, Diet Ostry, Don Price, Khoa N. Pham, Tim Wark

This work describes preliminary steps towards nano-scale reservoir computing using quantum dots.

Guided Self-Organization of Input-Driven Recurrent Neural Networks

no code implementations6 Sep 2013 Oliver Obst, Joschka Boedecker

We review attempts that have been made towards understanding the computational properties and mechanisms of input-driven dynamical systems like RNNs, and reservoir computing networks in particular.
