Robust reliability-based topology optimization under random-field material model
Trung Pham, Christopher Hoyle
This paper proposes an algorithm to find robust reliability-based topology optimized designs under a random-field material model. The initial design domain is made of linear elasti…
Reliability-based topology optimization under random-field material model
Trung Pham, Christopher Hoyle
This paper presents an algorithm for reliability-based topology optimization of linear elastic continua under random-field material model. The modelling random field is discretized…
Host galaxies and electromagnetic counterparts to binary neutron star mergers across the cosmic time: Detectability of GW170817-like events
Rosalba Perna, M. Celeste Artale, Yi-Han Wang +4
The detection of electromagnetic radiation (EM) accompanying the gravitational wave (GW) signal from the binary neutron star (BNS) merger GW170817 has revealed that these systems c…
Text Counterfactuals via Latent Optimization and Shapley-Guided Search
Quintin Pope, Xiaoli Z. Fern
We study the problem of generating counterfactual text for a classifier as a means for understanding and debugging classification. Given a textual input and a classification model,…
Optimal Sequential Stochastic Deployment of Multiple Passenger Robots
Chris, Lee, Graeme Best +1
We present a new algorithm for deploying passenger robots in marsupial robot systems. A marsupial robot system consists of a carrier robot (e.g., a ground vehicle), which is highly…
Dynamic probabilistic logic models for effective abstractions in RL
Harsha Kokel, Arjun Manoharan, Sriraam Natarajan +2
State abstraction enables sample-efficient learning and better task transfer in complex reinforcement learning environments. Recently, we proposed RePReL (Kokel et al. 2021), a hie…
