DinoBloom: A Foundation Model for Generalizable Cell Embeddings in Hematology

2 code implementations7 Apr 2024 Valentin Koch, Sophia J. Wagner, Salome Kazeminia, Ece Sancar, Matthias Hehr, Julia Schnabel, Tingying Peng, Carsten Marr

In hematology, computational models offer significant potential to improve diagnostic accuracy, streamline workflows, and reduce the tedious work of analyzing single cells in peripheral blood or bone marrow smears.

Low-resource finetuning of foundation models beats state-of-the-art in histopathology

1 code implementation9 Jan 2024 Benedikt Roth, Valentin Koch, Sophia J. Wagner, Julia A. Schnabel, Carsten Marr, Tingying Peng

Recently, foundation models in computer vision showed that leveraging huge amounts of data through supervised or self-supervised learning improves feature quality and generalizability for a variety of tasks.

Local Attention Graph-based Transformer for Multi-target Genetic Alteration Prediction

1 code implementation13 May 2022 Daniel Reisenbüchler, Sophia J. Wagner, Melanie Boxberg, Tingying Peng

Classical multiple instance learning (MIL) methods are often based on the identical and independent distributed assumption between instances, hence neglecting the potentially rich contextual information beyond individual entities.

S5CL: Unifying Fully-Supervised, Self-Supervised, and Semi-Supervised Learning Through Hierarchical Contrastive Learning

1 code implementation14 Mar 2022 Manuel Tran, Sophia J. Wagner, Melanie Boxberg, Tingying Peng

Evaluations of our framework on two public histopathological datasets show strong improvements in the case of sparse labels: for a H&E-stained colorectal cancer dataset, the accuracy increases by up to 9% compared to supervised cross-entropy loss; for a highly imbalanced dataset of single white blood cells from leukemia patient blood smears, the F1-score increases by up to 6%.
