Using a Variational Autoencoder to Learn Valid Search Spaces of Safely Monitored Autonomous Robots for Last-Mile Delivery

1 code implementation6 Mar 2023 Peter J. Bentley, Soo Ling Lim, Paolo Arcaini, Fuyuki Ishikawa

We also show that when COIL has learned its latent representation, it can optimize 10% faster than the GA, making it a good choice for daily re-optimization of robots where delivery requests for each day are allocated to robots while maintaining safe numbers of robots running at once.

The Agent-based Modelling for Human Behaviour Special Issue

no code implementations3 Feb 2023 Soo Ling Lim, Peter J. Bentley

If human societies are so complex, then how can we hope to understand them?

Temporally Extended Successor Representations

no code implementations25 Sep 2022 Matthew J. Sargent, Peter J. Bentley, Caswell Barry, William de Cothi

We show that in environments with dynamic reward structure, t-SR is able to leverage both the flexibility of the successor representation and the abstraction afforded by temporally extended actions.

Kill Chaos with Kindness: Agreeableness Improves Team Performance Under Uncertainty

no code implementations9 Aug 2022 Soo Ling Lim, Peter J. Bentley, Randall S. Peterson, Xiaoran Hu, JoEllyn Prouty McLaren

Our finding is that the dependency between team performance and Agreeableness is moderated by task uncertainty.

PiNet: Attention Pooling for Graph Classification

1 code implementation11 Aug 2020 Peter Meltzer, Marcelo Daniel Gutierrez Mallea, Peter J. Bentley

We propose PiNet, a generalised differentiable attention-based pooling mechanism for utilising graph convolution operations for graph level classification.

PiNet: A Permutation Invariant Graph Neural Network for Graph Classification

1 code implementation8 May 2019 Peter Meltzer, Marcelo Daniel Gutierrez Mallea, Peter J. Bentley

We propose an end-to-end deep learning learning model for graph classification and representation learning that is invariant to permutation of the nodes of the input graphs.

Capsule Neural Networks for Graph Classification using Explicit Tensorial Graph Representations

no code implementations22 Feb 2019 Marcelo Daniel Gutierrez Mallea, Peter Meltzer, Peter J. Bentley

Building on prior work combining explicit tensor representations with a standard image-based classifier, we propose a model to perform graph classification by extracting fixed size tensorial information from each graph in a given set, and using a Capsule Network to perform classification.
