Examining Modality Incongruity in Multimodal Federated Learning for Medical Vision and Language-based Disease Detection

no code implementations7 Feb 2024 Pramit Saha, Divyanshu Mishra, Felix Wagner, Konstantinos Kamnitsas, J. Alison Noble

Secondly, we introduce a modality imputation network (MIN) pre-trained in a multimodal client for modality translation in unimodal clients and investigate its potential towards mitigating the missing modality problem.

Federated Learning Imputation

The built environment and induced transport CO2 emissions: A double machine learning approach to account for residential self-selection

no code implementations7 Dec 2023 Florian Nachtigall, Felix Wagner, Peter Berrill, Felix Creutzig

Understanding why travel behavior differs between residents of urban centers and suburbs is key to sustainable urban planning.

Post-Deployment Adaptation with Access to Source Data via Federated Learning and Source-Target Remote Gradient Alignment

1 code implementation31 Aug 2023 Felix Wagner, Zeju Li, Pramit Saha, Konstantinos Kamnitsas

This paper challenges this assumption and introduces FedPDA, a novel adaptation framework that brings the utility of learning from remote data from Federated Learning into PDA.

Federated Learning Lesion Classification +1

Using machine learning to understand causal relationships between urban form and travel CO2 emissions across continents

1 code implementation31 Aug 2023 Felix Wagner, Florian Nachtigall, Lukas Franken, Nikola Milojevic-Dupont, Rafael H. M. Pereira, Nicolas Koch, Jakob Runge, Marta Gonzalez, Felix Creutzig

Here, we address all three gaps via causal graph discovery and explainable machine learning to detect urban form effects on intra-city car travel, based on mobility data of six cities across three continents.

Causal Discovery Specificity

Modality Cycles with Masked Conditional Diffusion for Unsupervised Anomaly Segmentation in MRI

1 code implementation30 Aug 2023 Ziyun Liang, Harry Anthony, Felix Wagner, Konstantinos Kamnitsas

Furthermore, we combine image translation with a masked conditional diffusion model, which attempts to `imagine' what tissue exists under a masked area, further exposing unknown patterns as the generative model fails to recreate them.

Nonlinear pile-up separation with LSTM neural networks for cryogenic particle detectors

no code implementations13 Dec 2021 Felix Wagner

In high-background or calibration measurements with cryogenic particle detectors, a significant share of the exposure is lost due to pile-up of recoil events.
