Self-Reproduction and Evolution in Cellular Automata: 25 Years after Evoloops

no code implementations6 Feb 2024 Hiroki Sayama, Chrystopher L. Nehaniv

The year of 2024 marks the 25th anniversary of the publication of evoloops, an evolutionary variant of Chris Langton's self-reproducing loops which proved that Darwinian evolution of self-reproducing organisms by variation and natural selection is possible within deterministic cellular automata.

How Do Human Users Teach a Continual Learning Robot in Repeated Interactions?

1 code implementation30 Jun 2023 Ali Ayub, Jainish Mehta, Zachary De Francesco, Patrick Holthaus, Kerstin Dautenhahn, Chrystopher L. Nehaniv

Continual learning (CL) has emerged as an important avenue of research in recent years, at the intersection of Machine Learning (ML) and Human-Robot Interaction (HRI), to allow robots to continually learn in their environments over long-term interactions with humans.

A Personalized Household Assistive Robot that Learns and Creates New Breakfast Options through Human-Robot Interaction

no code implementations30 Jun 2023 Ali Ayub, Chrystopher L. Nehaniv, Kerstin Dautenhahn

In this paper, we present a cognitive architecture for a household assistive robot that can learn personalized breakfast options from its users and then use the learned knowledge to set up a table for breakfast.

Continual Learning through Human-Robot Interaction -- Human Perceptions of a Continual Learning Robot in Repeated Interactions

1 code implementation22 May 2023 Ali Ayub, Zachary De Francesco, Patrick Holthaus, Chrystopher L. Nehaniv, Kerstin Dautenhahn

Our results suggest that participants' perceptions of trust, competence, and usability of a continual learning robot significantly decrease over multiple sessions if the robot forgets previously learned objects.

Don't Forget to Buy Milk: Contextually Aware Grocery Reminder Household Robot

no code implementations19 Jul 2022 Ali Ayub, Chrystopher L. Nehaniv, Kerstin Dautenhahn

The robot can also use the learned knowledge to correctly predict missing items over multiple weeks and it is robust against sensory and perceptual errors.

Measuring Time with Minimal Clocks

no code implementations17 Jun 2019 Andrei D. Robu, Christoph Salge, Chrystopher L. Nehaniv, Daniel Polani

Clock cascades show a "condensation effect" and the composite clock shows various regimes of markedly different dynamics.

Computational Understanding and Manipulation of Symmetries

no code implementations21 Aug 2009 Attila Egri-Nagy, Chrystopher L. Nehaniv

For natural and artificial systems with some symmetry structure, computational understanding and manipulation can be achieved without learning by exploiting the algebraic structure.
