Deep Generative Classification of Blood Cell Morphology

1 code implementation16 Aug 2024 Simon Deltadahl, Julian Gilbey, Christine Van Laer, Nancy Boeckx, Mathie Leers, Tanya Freeman, Laura Aiken, Timothy Farren, Matthew Smith, Mohamad Zeina, BloodCounts! Consortium, Concetta Piazzese, Joseph Taylor, Nicholas Gleadall, Carola-Bibiane Schönlieb, Suthesh Sivapalaratnam, Michael Roberts, Parashkev Nachev

Accurate classification of haematological cells is critical for diagnosing blood disorders, but presents significant challenges for machine automation owing to the complexity of cell morphology, heterogeneities of biological, pathological, and imaging characteristics, and the imbalance of cell type frequencies.

FedMAP: Unlocking Potential in Personalized Federated Learning through Bi-Level MAP Optimization

1 code implementation29 May 2024 Fan Zhang, Carlos Esteve-Yagüe, Sören Dittmer, Carola-Bibiane Schönlieb, Michael Roberts

This study contributes to PFL by establishing a solid theoretical foundation for the proposed method and offering a robust, ready-to-use framework that effectively addresses the challenges posed by non-IID data in FL.

Personalized Federated Learning

The curious case of the test set AUROC

1 code implementation19 Dec 2023 Michael Roberts, Alon Hazan, Sören Dittmer, James H. F. Rudd, Carola-Bibiane Schönlieb

Whilst the size and complexity of ML models have rapidly and significantly increased over the past decade, the methods for assessing their performance have not kept pace.

Estimating defection in subscription-type markets: empirical analysis from the scholarly publishing industry

no code implementations18 Nov 2022 Michael Roberts, J. Ignacio Deza, Hisham Ihshaish, Yanhui Zhu

We show that this approach can be both accurate as well as uniquely useful in the business-to-business context, with which the scholarly publishing business model shares similarities.

Navigating the challenges in creating complex data systems: a development philosophy

no code implementations21 Oct 2022 Sören Dittmer, Michael Roberts, Julian Gilbey, Ander Biguri, AIX-COVNET Collaboration, Jacobus Preller, James H. F. Rudd, John A. D. Aston, Carola-Bibiane Schönlieb

In this perspective, we argue that despite the democratization of powerful tools for data science and machine learning over the last decade, developing the code for a trustworthy and effective data science system (DSS) is getting harder.

Chan-Vese Reformulation for Selective Image Segmentation

no code implementations21 Nov 2018 Michael Roberts, Jack Spencer

Selective segmentation involves incorporating user input to partition an image into foreground and background, by discriminating between objects of a similar type.
