Distributional Gaussian Processes Layers for Out-of-Distribution Detection

no code implementations27 Jun 2022 Sebastian G. Popescu, David J. Sharp, James H. Cole, Konstantinos Kamnitsas, Ben Glocker

Moreover, by applying the same segmentation model to out-of-distribution data (i. e., images with pathology such as brain tumors), we show that our uncertainty estimates result in out-of-distribution detection that outperforms the capabilities of previous Bayesian networks and reconstruction-based approaches that learn normative distributions.

Continual Learning Using Task Conditional Neural Networks

no code implementations29 Sep 2021 Honglin Li, Frieder Ganz, David J. Sharp, Payam M. Barnaghi

The proposed model can continually learn and embed new tasks into the model without losing the information about previously learned tasks.

Distributional Gaussian Process Layers for Outlier Detection in Image Segmentation

no code implementations28 Apr 2021 Sebastian G. Popescu, David J. Sharp, James H. Cole, Konstantinos Kamnitsas, Ben Glocker

We propose a parameter efficient Bayesian layer for hierarchical convolutional Gaussian Processes that incorporates Gaussian Processes operating in Wasserstein-2 space to reliably propagate uncertainty.

An attention model to analyse the risk of agitation and urinary tract infections in people with dementia

1 code implementation18 Jan 2021 Honglin Li, Roonak Rezvani, Magdalena Anita Kolanko, David J. Sharp, Maitreyee Wairagkar, Ravi Vaidyanathan, Ramin Nilforooshan, Payam Barnaghi

We have developed an integrated platform to collect in-home sensor data and performed an observational study to apply machine learning models for agitation and UTI risk analysis.
