Open-ended search for environments and adapted agents using MAP-Elites

1 code implementation2 May 2023 Emma Stensby Norstein, Kai Olav Ellefsen, Kyrre Glette

We want to move one step closer to creating simulated environments similar to the diverse real world, where agents can both find solvable tasks, and adapt to them.

Co-optimising Robot Morphology and Controller in a Simulated Open-Ended Environment

1 code implementation7 Apr 2021 Emma Hjellbrekke Stensby, Kai Olav Ellefsen, Kyrre Glette

We compare the diversity, fitness and robustness of agents evolving in environments generated by POET to agents evolved in handcrafted curricula of environments.

A Model of WiFi Performance With Bounded Latency

no code implementations29 Jan 2021 Bjørn Ivar Teigen, Neil Davies, Kai Olav Ellefsen, Tor Skeie, Jim Torresen

Instead of computing throughput numbers from a steady-state analysis of a Markov chain, we explicitly model latency and packet loss.

Quality and Diversity in Evolutionary Modular Robotics

no code implementations5 Aug 2020 Jørgen Nordmoen, Frank Veenstra, Kai Olav Ellefsen, Kyrre Glette

In this paper we compare a single objective Evolutionary Algorithm with two diversity promoting search algorithms; a Multi-Objective Evolutionary Algorithm and MAP-Elites a Quality Diversity algorithm, for the difficult problem of evolving control and morphology in modular robotics.

Self-Adapting Goals Allow Transfer of Predictive Models to New Tasks

no code implementations4 Apr 2019 Kai Olav Ellefsen, Jim Torresen

In this paper, we extend a recent deep learning architecture which learns a predictive model of the environment that aims to predict only the value of a few key measurements, which are be indicative of an agent's performance.

Guiding Neuroevolution with Structural Objectives

no code implementations12 Feb 2019 Kai Olav Ellefsen, Joost Huizinga, Jim Torresen

However, on a problem where the optimal decomposition is less obvious, the structural diversity objective is found to outcompete other structural objectives -- and this technique can even increase performance on problems without any decomposable structure at all.

How do Mixture Density RNNs Predict the Future?

no code implementations23 Jan 2019 Kai Olav Ellefsen, Charles Patrick Martin, Jim Torresen

Gaining a better understanding of how and what machine learning systems learn is important to increase confidence in their decisions and catalyze further research.

Multiobjective Coverage Path Planning: Enabling Automated Inspection of Complex, Real-World Structures

no code implementations22 Jan 2019 Kai Olav Ellefsen, Herman A. Lepikson, Jan C. Albiez

We here test our method on a set of inspection targets with large variation in size and complexity, and compare its performance with two state-of-the-art methods for complete coverage path planning.

Deep Predictive Models in Interactive Music

no code implementations31 Jan 2018 Charles P. Martin, Kai Olav Ellefsen, Jim Torresen

Musical performance requires prediction to operate instruments, to perform in groups and to improvise.
