Federated Self-supervised Learning for Video Understanding

1 code implementation5 Jul 2022 Yasar Abbas Ur Rehman, Yan Gao, Jiajun Shen, Pedro Porto Buarque de Gusmao, Nicholas Lane

The ubiquity of camera-enabled mobile devices has lead to large amounts of unlabelled video data being produced at the edge.

A Channel Coding Benchmark for Meta-Learning

1 code implementation15 Jul 2021 Rui Li, Ondrej Bohdal, Rajesh Mishra, Hyeji Kim, Da Li, Nicholas Lane, Timothy Hospedales

We use our MetaCC benchmark to study several aspects of meta-learning, including the impact of task distribution breadth and shift, which can be controlled in the coding problem.


Predicting Patient Outcomes with Graph Representation Learning

1 code implementation11 Jan 2021 Emma Rocheteau, Catherine Tong, Petar Veličković, Nicholas Lane, Pietro Liò

Recent work on predicting patient outcomes in the Intensive Care Unit (ICU) has focused heavily on the physiological time series data, largely ignoring sparse data such as diagnoses and medications.

Single Shot Structured Pruning Before Training

no code implementations1 Jul 2020 Joost van Amersfoort, Milad Alizadeh, Sebastian Farquhar, Nicholas Lane, Yarin Gal

We introduce a method to speed up training by 2x and inference by 3x in deep neural networks using structured pruning applied before training.

Distilling Knowledge from Ensembles of Acoustic Models for Joint CTC-Attention End-to-End Speech Recognition

3 code implementations19 May 2020 Yan Gao, Titouan Parcollet, Nicholas Lane

In the specific context of Automatic Speech Recognition (ASR), distillation from ensembles of acoustic models has recently shown promising results in increasing recognition performance.

Quaternion Neural Networks for Multi-channel Distant Speech Recognition

1 code implementation18 May 2020 Xinchi Qiu, Titouan Parcollet, Mirco Ravanelli, Nicholas Lane, Mohamed Morchid

In this paper, we propose to capture these inter- and intra- structural dependencies with quaternion neural networks, which can jointly process multiple signals as whole quaternion entities.

The Surprising Behavior Of Graph Neural Networks

no code implementations25 Sep 2019 Vivek Kothari, Catherine Tong, Nicholas Lane

We highlight a lack of understanding of the behaviour of Graph Neural Networks (GNNs) in various topological contexts.

Robust Cross-View Gait Recognition with Evidence: A Discriminant Gait GAN (DiGGAN) Approach

1 code implementation26 Nov 2018 BingZhang Hu, Yu Guan, Yan Gao, Yang Long, Nicholas Lane, Thomas Ploetz

Gait as a biometric trait has attracted much attention in many security and privacy applications such as identity recognition and authentication, during the last few decades.
