Toward collision-free trajectory for autonomous and pilot-controlled unmanned aerial vehicles

no code implementations18 Sep 2023 Kaya Kuru, John Michael Pinder, Benjamin Jon Watkinson, Darren Ansell, Keith Vinning, Lee Moore, Chris Gilbert, Aadithya Sujit, David Jones

For drones, as safety-critical systems, there is an increasing need for onboard detect & avoid (DAA) technology i) to see, sense or detect conflicting traffic or imminent non-cooperative threats due to their high mobility with multiple degrees of freedom and the complexity of deployed unstructured environments, and subsequently ii) to take the appropriate actions to avoid collisions depending upon the level of autonomy.

Causal Estimation of User Learning in Personalized Systems

no code implementations1 Jun 2023 Evan Munro, David Jones, Jennifer Brennan, Roland Nelet, Vahab Mirrokni, Jean Pouget-Abadie

In online platforms, the impact of a treatment on an observed outcome may change over time as 1) users learn about the intervention, and 2) the system personalization, such as individualized recommendations, change over time.

A lightweight Transformer-based model for fish landmark detection

no code implementations13 Sep 2022 Alzayat Saleh, David Jones, Dean Jerry, Mostafa Rahimi Azghadi

Transformer-based models, such as the Vision Transformer (ViT), can outperform onvolutional Neural Networks (CNNs) in some vision tasks when there is sufficient training data.

Using AntiPatterns to avoid MLOps Mistakes

no code implementations30 Jun 2021 Nikhil Muralidhar, Sathappah Muthiah, Patrick Butler, Manish Jain, Yu Yu, Katy Burne, Weipeng Li, David Jones, Prakash Arunachalam, Hays 'Skip' McCormick, Naren Ramakrishnan

We describe lessons learned from developing and deploying machine learning models at scale across the enterprise in a range of financial analytics applications.

Distinguishing artefacts: evaluating the saturation point of convolutional neural networks

no code implementations21 May 2021 Ric Real, James Gopsill, David Jones, Chris Snider, Ben Hicks

Prior work has shown Convolutional Neural Networks (CNNs) trained on surrogate Computer Aided Design (CAD) models are able to detect and classify real-world artefacts from photographs.

Intensity Harmonization for Airborne LiDAR

no code implementations4 May 2021 David Jones, Nathan Jacobs

We show that our method performs as well as the best baseline in areas with similar intensity distributions, and outperforms all baselines in areas with different intensity distributions.

Physics of Eclipsing Binaries. V. General Framework for Solving the Inverse Problem

1 code implementation30 Jun 2020 Kyle E Conroy, Angela Kochoska, Daniel Hey, Herbert Pablo, Kelly M Hambleton, David Jones, Joseph Giammarco, Michael Abdul-Masih, Andrej Prsa

The inverse problem, obtaining orbital and stellar parameters given observational data, is more complicated and computationally expensive as it requires generating a large set of forward-models to determine which set of parameters and uncertainties best represent the available observational data.

Evolutionary Deep Learning to Identify Galaxies in the Zone of Avoidance

no code implementations6 Mar 2019 David Jones, Anja Schroeder, Geoff Nitschke

The Zone of Avoidance makes it difficult for astronomers to catalogue galaxies at low latitudes to our galactic plane due to high star densities and extinction.
