Rapid Open-World Adaptation by Adaptation Principles Learning

no code implementations18 Dec 2023 Cheng Xue, Ekaterina Nikonova, Peng Zhang, Jochen Renz

This is an important characteristic of intelligent agents, as it allows them to continue to function effectively in novel or unexpected situations, but still stands as a critical challenge for deep reinforcement learning (DRL).

NovPhy: A Testbed for Physical Reasoning in Open-world Environments

1 code implementation3 Mar 2023 Chathura Gamage, Vimukthini Pinto, Cheng Xue, Peng Zhang, Ekaterina Nikonova, Matthew Stephenson, Jochen Renz

But is it enough to only have physical reasoning capabilities to operate in a real physical environment?

Don't do it: Safer Reinforcement Learning With Rule-based Guidance

no code implementations28 Dec 2022 Ekaterina Nikonova, Cheng Xue, Jochen Renz

During training, reinforcement learning systems interact with the world without considering the safety of their actions.

Measuring Difficulty of Novelty Reaction

no code implementations28 Jul 2022 Ekaterina Nikonova, Cheng Xue, Vimukthini Pinto, Chathura Gamage, Peng Zhang, Jochen Renz

In this paper, we propose to define the novelty reaction difficulty as a relative difficulty of performing the known task after the introduction of the novelty.

Phy-Q as a measure for physical reasoning intelligence

1 code implementation31 Aug 2021 Cheng Xue, Vimukthini Pinto, Chathura Gamage, Ekaterina Nikonova, Peng Zhang, Jochen Renz

Inspired by how human IQ is calculated, we define the physical reasoning quotient (Phy-Q score) that reflects the physical reasoning intelligence of an agent using the physical scenarios we considered.

Deep Q-Network for Angry Birds

1 code implementation4 Oct 2019 Ekaterina Nikonova, Jakub Gemrot

Angry Birds is a popular video game in which the player is provided with a sequence of birds to shoot from a slingshot.

Learning Underlying Physical Properties From Observations For Trajectory Prediction

no code implementations25 Sep 2019 Ekaterina Nikonova, Jochen Renz

We show that by using physical laws together with deep learning we achieve a better human-interpretability of learned physical properties, transfer of knowledge to a game with similar physics and very accurate predictions for previously unseen data.
