Cluster Metric Sensitivity to Irrelevant Features

no code implementations19 Feb 2024 Miles McCrory, Spencer A. Thomas

We observe a resilience to very high proportions of irrelevant features for adjusted rand index (ARI) and normalised mutual information (NMI) when the irrelevant features are Gaussian distributed.

A Generic Self-Supervised Framework of Learning Invariant Discriminative Features

no code implementations14 Feb 2022 Foivos Ntelemis, Yaochu Jin, Spencer A. Thomas

Specifically, the prior transformation functions are replaced with a self-transformation mechanism, derived through an unsupervised training process of adversarial training, for imposing invariant representations.

Enhanced Transfer Learning Through Medical Imaging and Patient Demographic Data Fusion

no code implementations29 Nov 2021 Spencer A. Thomas

In this work we examine the performance enhancement in classification of medical imaging data when image features are combined with associated non-image data.

Combining Image Features and Patient Metadata to Enhance Transfer Learning

no code implementations8 Oct 2021 Spencer A. Thomas

In this work, we compare the performance of six state-of-the-art deep neural networks in classification tasks when using only image features, to when these are combined with patient metadata.

Information Maximization Clustering via Multi-View Self-Labelling

1 code implementation12 Mar 2021 Foivos Ntelemis, Yaochu Jin, Spencer A. Thomas

Specifically, the proposed clustering objective employs mutual information, and maximizes the dependency between the integrated discrete representation and a discrete probability distribution.

Image Clustering using an Augmented Generative Adversarial Network and Information Maximization

1 code implementation8 Nov 2020 Foivos Ntelemis, Yaochu Jin, Spencer A. Thomas

Image clustering has recently attracted significant attention due to the increased availability of unlabelled datasets.
