Computational limits to the legibility of the imaged human brain

1 code implementation23 Aug 2023 James K Ruffle, Robert J Gray, Samia Mohinta, Guilherme Pombo, Chaitanya Kaul, Harpreet Hyare, Geraint Rees, Parashkev Nachev

It remains unknown whether the difficulty arises from the absence of individuating biological patterns within the brain, or from limited power to access them with the models and compute at our disposal.

mmSense: Detecting Concealed Weapons with a Miniature Radar Sensor

no code implementations28 Feb 2023 Kevin Mitchell, Khaled Kassem, Chaitanya Kaul, Valentin Kapitany, Philip Binner, Andrew Ramsay, Roderick Murray-Smith, Daniele Faccio

For widespread adoption, public security and surveillance systems must be accurate, portable, compact, and real-time, without impeding the privacy of the individuals being observed.

The Fully Convolutional Transformer for Medical Image Segmentation

2 code implementations1 Jun 2022 Athanasios Tragakis, Chaitanya Kaul, Roderick Murray-Smith, Dirk Husmeier

To address this shortcoming, we propose The Fully Convolutional Transformer (FCT), which builds on the proven ability of Convolutional Neural Networks to learn effective image representations, and combines them with the ability of Transformers to effectively capture long-term dependencies in its inputs.

Rotation Equivariant 3D Hand Mesh Generation from a Single RGB Image

no code implementations25 Nov 2021 Joshua Mitton, Chaitanya Kaul, Roderick Murray-Smith

Our rotation equivariant model outperforms state-of-the-art methods on a real-world dataset and we demonstrate that it accurately captures the shape and pose in the generated meshes under rotation of the input hand.

CpT: Convolutional Point Transformer for 3D Point Cloud Processing

no code implementations21 Nov 2021 Chaitanya Kaul, Joshua Mitton, Hang Dai, Roderick Murray-Smith

It achieves this feat due to its effectiveness in creating a novel and robust attention-based point set embedding through a convolutional projection layer crafted for processing dynamically local point set neighbourhoods.

Survey: Leakage and Privacy at Inference Time

no code implementations4 Jul 2021 Marija Jegorova, Chaitanya Kaul, Charlie Mayor, Alison Q. O'Neil, Alexander Weir, Roderick Murray-Smith, Sotirios A. Tsaftaris

Leakage of data from publicly available Machine Learning (ML) models is an area of growing significance as commercial and government applications of ML can draw on multiple sources of data, potentially including users' and clients' sensitive data.

FatNet: A Feature-attentive Network for 3D Point Cloud Processing

no code implementations7 Apr 2021 Chaitanya Kaul, Nick Pears, Suresh Manandhar

The application of deep learning to 3D point clouds is challenging due to its lack of order.
